From Malta comes this look inside the new studios of RTK 103FM, courtesy of AEQ. The facility features AoIP infrastructure and visual radio elements.

RTK Ltd. is the media company of the Catholic Church in Malta; it is owned by Beacon Media Group.

A team from DAB Electronica Ltd. led by Alan Gatt led the technical infrastructures and studio build.

“Studying different alternatives, eventually the system decided upon was entirely audio over IP based, except for the local inputs and outputs in terms of microphones, headphones and monitoring,” AEQ reported in a project summary.

Exhibo of Italy installed two auto-control operated studios using 12-fader AEQ Forum Split IP consoles. Studio One is a main studio with provision for three guests; Studio Two allows for am anchor or DJ to host up to six guests.

“Either studio can be controlled form either console thanks to the possibility to share all the stations audio resources over the AoIP network,” AEQ wrote.

“To make antennae, studio and playout switching simpler and automated, a NetBox32 MX with RTC option was installed, thus providing a 64×64 non-blocking routing Matrix for AoIP, analog and digital audio sources. This unit is used for format conversion, thus allowing for any analog or digital source to become part of the AoIP Multi-channel network.”

Automation, scheduling and playout are from WideOrbit and connected to the AoIP network with Dante Virtual Soundcards.

“As Wideorbit allows embedding third-party commands as objects in their lists and schedules, the Virtual GPO protocols for AEQ equipment can trigger macros and salvos for any of AEQ’s AoIP networked equipment,” AEQ said.

“This becomes very handy when general programming is switching for news on the hour. The other way around, it allows the DJ to trigger the play-out, cue a song etc., directly form the console control surface or to start the control of the microphones in the other studio, etc.”

The studios use Sennheiser MK4 Condenser Mics and HM300 Headphones, as well as an AEQ Systel IP 16 Talk-show and phone-in system with three SystelSet+.

Visual radio support is provided by BroadcastPix video switchers. Each studio has three JVC HD PTZ cameras. Any channel or audio source in the installation can trigger a camera setting, video clip, transition or sequence available on the Broadcast Pix system.

AEQ Phoenix ALIO portable devices are used for remote/OB work, connected via 4G router or standard internet. “Normally Opus encoding is used for either voice-quality of full-bandwidth music.” Connectivity at the station is by a Phoenix Venus 3 with AoIP networking; the ControlPhoenix application allows a technician at the studio to control the local and remote codecs.

Two Phoenix Venus 3s with AoIP are used to create the studio-transmitter link and return telemetry.

DHD Audio has introduced a firmware update for its broadcast audio mixing consoles, routers and control interfaces.

“New functions have been integrated to make operation easier, faster and more flexible,” the company stated. “Also being introduced are flat table-mount versions of the RX2 and SX2 mixers.”

DHD makes five audio consoles that can be paired with several cores of different capacities and equipped with a variety of interface modules. International Sales Manager Christoph Gottert said these products are used by both radio and TV stations.

“Our latest firmware additions expand the capabilities of version 9.1 which we announced in Q1. That update included support for Unicode character sets such as Chinese, Russian, Japanese and Korean, Snapshots App and Labels App, enhanced log-in, hot configuration and refinements to the DHD REST API,” he was quoted saying.

“We are now introducing two additional web apps, Assist App and System App, plus an advanced SNMP interface.”

Assist App is a browser-based application allowing remote operation of a DHD mixing desk from a tablet, laptop or desktop PC. The remote user can control fader and central modules and view the integral displays.

“Assist App enables a technician to support DJs during their daily operation without being on-site,” the company said. It’s compatible with DHD RX2 and SX2 mixers and TX touch panels.

System App provides control to configure and supervise a DHD system. Its interface includes IP address assignment and web connection management. “Detailed information for each module connected to the core is displayed, including serial numbers, temperature and uptime.” Local and IP-connected remote devices can be seen.

SNMP is for use where the mixers and routers are part of a large infrastructure and where devices are centrally managed. It’s available for XC2, XD2 and XS2 cores, and will be available for AES67/Ravenna interfaces this year.

DHD posted a video demo about these firmware features:

Please let me add my 2 cents’ worth regarding music tracks that have been clipped and trashed with “brick-wall” audio processing (May 27, Opinion section).

The next time your radio station receives a CD or file that has been brick-wall limited, simply return it to the sender with an impersonal form letter saying “The music you have supplied is defective and/or unsuitable for broadcast. We do not air any material that is detrimental to our listenership,” or words to that effect.

If a few hundred radio stations return a few thousand, refusing to air them, perhaps the music producers and record labels will fix the problem.

We can only hope!

CGR Radio Networks and the Northwest Audio Information Service in Vancouver, Wash., serve blind, visually impaired and older listeners with news and entertainment programming.

We told you about these services shortly after owner Gerald Gaule launched them seven years ago. He describes them as a labor of love.

Gaule worked under the late Jerry Delaunay at the former Golden Hours radio reading service of Oregon Public Broadcasting for 13 years. He credits him with helping influence his interest in public service broadcasting. Gaule is not only the owner of CGR/NAIS but the program director, music director and chief engineer, running these streams from his home.

Now a member of the International Association of Audio Information Services, CGR-NWAIS Radio has three online streams, all heard on the Voscast online platform. The main service also is carried on FM subcarriers of KFAE(FM) in Richland, Wash., and KPBX(FM) Spokane.

We caught up with Gaule to ask about how the project is going.

Radio World: Describe your operations.

Gerald Gaule: There are three services. Number One is the main service, offering news, information, community, educational and entertainment programming from many sources such as The IAAIS Program Share, ACB Radio, Pacifica Archives and more, as well as programming in over 40 languages for the blind from book readings, etc. Old-time radio and nostalgia are offered.

CGR Number 2 is more arts, entertainment and secondary reading services. Number 3 is a new Spanish service for the blind and visually prepared.

I also offer local news and programming that is not offered by any LPFM, and I try to think outside the box.

RW: How many people do you think you reach?

Gaule: I would say 900 to 1,200 listeners per day between the stations.

The numbers are nice, but even if there is only one and if I make a difference for a few minutes, if something they like made their day, it is priceless.

Listener ages are anywhere from 54 to 90.

RW: These seem like hard times for radio reading services. What’s your secret?

Gaule: It is very hard times. My operations are run from my apartment; I handle all the roles, from engineer to MP, PD, OM and all; and I work from here due to health and disability issues. Overhead is very low.

RW: How has the pandemic affected what you do?

Gaule: It has not affected me that since I work from home and even before it.

RW: What else should we know?

Gaule: It is a simple operation trying to go above and beyond. I am always looking to expand, to grow beyond the two FM stations KFAE and KPBX on their 67 kHz SCAs. I’d like to partner with any cable access channel or even through a TV digital sub channel, even for a few hours a day.

The National Association of Broadcasters has decided to move the 2021 NAB Show from April to October of next year.

President/CEO Gordon Smith broke the news in an announcement to the industry. The new dates are Oct. 9 to 13, 2021, in Las Vegas.

Also announced: the 2021 fall Radio Show will be held concurrently in Vegas.

The question of what NAB might do in 2021 with the huge spring event — after cancelling it in 2020 just a few weeks before the show in the face of COVID-19 — has been a pressing and closely watched one as the industry moved into autumn for the Northern Hemisphere and as organizations began planning next year’s travel (or lack of it) without clarity on when the world health situation would ease.

The decision affects a lot of people. Registration at the most recent physical NAB Show in 2019 was reported by the association at around 91,460 people, more than a quarter of them from abroad.

Smith said NAB was aware of “a good deal of reluctance around participating in large events in the first half of next year.” He wrote that the pandemic “remains a significant threat and the evidence suggests it will be well into next year before it could be under control in the U.S.”

He said NAB also had concerns “around being able to deliver the type of event in April that will not only drive results, but one that can be produced safely for all involved and without significant limitations on the experience.”

“Moving NAB Show to October means we are considering alternative 2021 dates for NAB Show New York, held annually in October,” Smith wrote.

“On the plus side, the 2021 Radio Show will co-locate with NAB Show in Las Vegas, as will NAB’s Sales and Management Television Exchange; and there is opportunity to add additional partner events.” (Next year’s Radio Show had been slated for New Orleans.)

An NAB spokeswoman told Radio World that the following year’s spring show schedule is not affected; that convention is scheduled for April 23-27, 2022.

Smith didn’t mention other shows by name but wrote, “We have done our best to avoid direct conflicts with other domestic and international events, and have reached out to allied organizations and partners to both share our thinking in advance and to offer to work collaboratively toward turning this into an opportunity for all.” The IBC Show is another large event around that time of year; it is slated next year for mid-September.

Earlier, planners of another big Vegas show, the 2021 CES, announced that their event this coming January would be held virtually

Also today, Chris Brown, NAB’s EVP of conventions, wrote to exhibitor partners, “We did not make this decision lightly and we’d like to thank you for your continued support and guidance over the last few months as we considered your feedback while also monitoring the ongoing health and safety concerns around the fight to contain the pandemic in the U.S., the projected state of the economy and travel restrictions around the world.”

Brown told exhibitors that the NAB Show staff “will be in touch in the coming weeks to review next steps to reserve your participation in the 2021 NAB Show.” 

The full text of Gordon Smith’s announcement is below:

Dear NAB Show community,

I hope that you and your loved ones are well and staying safe. Although we truly miss seeing you in person, it has been fantastic to observe the industry come together in many ways to work through these challenging times, and it has been our pleasure to do our part to create connections via our new digital initiatives.

As we look ahead to 2021 and beyond, our top priority is to deliver a successful NAB Show. We recognize the vital role NAB Show plays as a driver of innovation and an economic engine for the global media and entertainment industry. With that in mind, it is critical we act on your behalf and in a way that will best serve the long-term interests of the industry. We have worked diligently over the last few weeks and months monitoring a range of variables, including health and safety concerns, economic indicators, industry developments and travel restrictions, to gain an understanding of overall trends and future conditions for holding a major event in 2021. We have also reached out extensively to the show community to collect feedback.

Through all of this we have witnessed growing concern and uncertainty over what the next six months will bring; enough that there appears to be a good deal of reluctance around participating in large events in the first half of next year. The pandemic remains a significant threat and the evidence suggests it will be well into next year before it could be under control in the U.S. We also have our own concerns around being able to deliver the type of event in April that will not only drive results, but one that can be produced safely for all involved and without significant limitations on the experience.

Taking all of this into account and in the interest of supporting the business, health and safety concerns of our show community we have decided to move the 2021 NAB Show, previously scheduled for April 11–14, to October 9–13, 2021 in Las Vegas.

With any difficult decision, there are trade-offs. Moving NAB Show to October means we are considering alternative 2021 dates for NAB Show New York, held annually in October. On the plus side, the 2021 Radio Show will co-locate with NAB Show in Las Vegas as will NAB’s Sales and Management Television Exchange; and there is opportunity to add additional partner events. Beyond this, we have done our best to avoid direct conflicts with other domestic and international events, and have reached out to allied organizations and partners to both share our thinking in advance and to offer to work collaboratively toward turning this into an opportunity for all.

With a new date set for the 2021 NAB Show we are looking at the entirety of the calendar next year with fresh eyes. We plan to continue bringing the industry together in a number of ways. In the short-term, we are excited about the online events planned for next month – the Radio Show (October 5–9) and NAB’s Sales and Management Television Exchange (October 14–15). These signature events, combined with our virtual NAB Show New York (October 19–29), offer dynamic content and engagement opportunities all month long to bring the industry together to restart, reengage and refocus.

We are also committed to creating new and meaningful experiences to engage and connect with you throughout the year on NAB Amplify. This dynamic, year-round digital platform will extend the impact of NAB Show throughout the year by providing opportunities for networking, discovery and education.

Since the early stages of the current global crisis, we have done our best to balance our decision-making with the long-term interest of NAB members and the wider media and entertainment industry. We have not made this decision lightly and have relied on a great deal of feedback from the NAB Show community. We are grateful to our stakeholders and partners for engaging with us and supporting our decision. Amidst all of this, we have been reminded of what a great industry we serve. As always, we look forward to working with you to provide vital events and services to support these efforts, and to invigorate and propel the industry forward.

To celebrate 100 years of broadcasting, a Southern California radio station will take its listeners on a 10-decade listening ride — an audio time travel trip that will let it reimage itself using memorable jingles, audio sounders and soundbites from the past 100 years.

 It was in 1920 that KNX 1070 News Radio first launched when Fred Christian started station 6ADZ for the customers of his Electric Supply Co. Twenty months later, the electric supply company was issued the call sign KNX. Today, KNX reaches more than 1.24 million listeners across Southern California.

[Read John Schneider’s story “KNX: A Centennial Station”]

 This week the Entercom station has aired “KNX: A Century of Covering Southern California,” an eight-part on-air series commemorating its centennial anniversary and paying tribute to former employees who helped grow KNX 1070 News Radio into the only 24-hour news and traffic station in Southern California.

On the station’s official anniversary, Sept. 10, the station will take listeners down memory lane with everything from old advertisements to trendy jingles.

“The history of Southern California, this county and our world have been painted by so many legendary broadcasters over the years, which is a daily reminder of the historic brand that KNX is,” said Jeff Federman, regional president of Entercom Southern California.

[Read more stories about radio’s centennial celebrations]

KNX 1070 News Radio was a Southern California institution — it was on air before the Hollywood Sign appeared, the Santa Monica Pier and the Rose Bowl, according Ken Charles, brand manager for the station. “Just as iconic as any of our local treasures, KNX is a consistent part of the fabric of Southern California, serving as a breaking news resource for our communities, first responders and the nation,” he said.

Listeners can tune in to the celebration on KNX 1070 News Radio on air, as well as nationwide on the Radio.com app and online. Fans are also encouraged to connect with the station on social media.

Scott Dorsey wrote about a supposed Carrington event in 1972. I won’t dispute that. Maybe the solar activity was on that level.

I don’t think he meant to imply that due to our getting through the 1972 event, we have nothing to worry about now; but it is still important to point out that communications technology then was nowhere near as fragile and vulnerable to induced voltages on conductors as it is today.

The number of satellites in orbit at that time was relatively small. GPS was not in use or didn’t even exist.

Consumer electronics still consisted of a lot of vacuum tube circuitry. And telephones were all on twisted pair copper from central offices with Western Electric equipment, everything built to survive an atomic bomb blast.

Just look around right now and you’ll see that today we are substantially more at risk.

We now know that audio processing is needed for streaming, and for many of the same reasons that processing is needed for on-air. We also know that we can’t paint streaming with the same audio processing brush.

Here is why:

Fast time constants can interfere with the codec. The conventional approach of applying multiband gain control followed by fast compression to build uniform loudness and density from one music source to the next works beautifully for on-air, but it doesn’t work for streaming. This is because applying fast compression time constants increases the intermodulation and other distortion products that causes codecs to make mistakes and remove or add frequencies that it shouldn’t.

That can be bad for any stream, but it’s especially bad for low-bitrate streams that don’t have a lot of data bits to begin with. Processors designed for streaming applications use adaptive algorithms and other less extreme measures to create uniform loudness between songs.

Peak Overshoot is a problem. Unlike analog, digital audio gets ugly once it tries to go past 0 dBFS, the point at which there are simply no more bits left and nasty distortion ensues.

The recommended peak input level for most codecs is around –3 dBFS so a limiter is necessary to ensure that level is never exceeded. But not any old limiter will do. Aggressive limiting and its byproducts can be problematic because codecs can multiply the audibility of limiting to the point of being objectionable, and often at the expense of removing frequencies that add to the quality of music.

A good streaming processor will avoid aggressive limiting altogether. This is why in the case of StreamBlade, we designed the processor to anticipate overshoots earlier in the processing stages and designed specialized final limiters that don’t add the program density that can set off issues with the codec.

Nope. Just nope. We learned quickly that clipping is not a good idea for peak control of program streams because it creates harmonics that aren’t in the original program and because the encoder doesn’t know what to do with that. In some cases, it throws bits at the bad harmonics, so you actually get more … bad harmonics.

Clipping byproducts can sound much, much worse once a codec gets a hold of them. The good news is that streaming doesn’t need the pre-emphasis can of worms that got FM broadcasters into heavy clipping to be competitive, so clipping isn’t necessary or even desired for keeping peak levels in check.  

Stereo, not so much. Big swings in L–R can trick certain codecs into disproportionately encoding stereo energy rather than more “up front” and audible program content. We experimented with various codecs and bitrates in our lab and in the field, and we found that stereo can be applied in most cases if it’s done consistently and without the big L–R swings that skew the codec algorithm in favor of L–R over original content. The exception is extremely low bitrates, in which case mono is preferable.

The author of this tech tips commentary is director of sales engineering for RCS.

Zetta is a modern enterprise piece of radio automation software build by RCS, the worldwide leader in radio software, that can ingest mp3, wav and AAC files, convert them to a default audio format, automatically set the trim in, time out and segue points, and nondestructively normalize all audio with pitchless stretch and squeeze.

Needless to say, it’s a very powerful piece of software that can cater to any broadcaster.

So let’s dive into five things you may not have known that you can do in Zetta.

1.) Starting with customizing your Zetta user experience, did you know that users can have their own layouts, color schemes, attributes, and Library folders, and Administrators can control their staff with proper user right restrictions?

Configure Zetta the way you interpret Zetta. Create multiple layouts — one for on-air and another for production.

Users can define their own asset types (see above) or folders within the Library:

Configuration | System | Asset Types

as well as their own custom fields, like an “Outcue for Spots”:

Configuration | System | Custom Fields

For Administrators, define a user Role and Organization, then assign it to a specific User:

Configuration | Roles, Organization, Users

2.) What about integration? The majority of RCS products can make live, real-time updates within Zetta.

Users can automatically send their Aquira traffic log to Zetta with Aquira Sync, remotely broadcast live with Revma’s Conference App and keep your library and schedules in sync with 100% live GSelector Music Scheduling integration. Maximize your staff’s efficiency by adding audio, metadata and schedule changes — including live reconciliation, which are instantly reflected in GSelector or vice versa.

Users are no longer forced to make a change in automation and then repeat the process for your music scheduler.

3.) Zetta also allows markets to stay connected and share assets with Site Replication or Z-Cast. Simply put, think of Site Replication as a “pull,” in which users can share audio and metadata.

If Market A would like to be in sync with Market B, then we would configure Site Replication. If Market A merely wanted to send Market B certain audio, like spots, then they could utilize Z-Cast, which acts as a “push,” sending Market B Market A’s audio and metadata.

4.) As we continue to develop remote workflows, Zetta is equipped with Zetta2GO. It’s not an app or a download from an app store but a simple URL.

Zetta2GO allows users to continue to control the on-air product, broadcast live, add audio, make changes to the schedule and voice track from any device that has access to the Internet and proper securities, like a VPN.

Is your company limited on studio space? While in the office, quickly access Zetta2GO from any desk or have your production director work from home, importing mass audio files that are instantly available in your Library while your talent is safely broadcasting from the studio. Start with a Location:

Configuration | System | Location

and create a Zetta Auto Import folder:

Configuration | System | Auto Load

5.) Next, it’s time to talk about the cloud, specifically, Zetta Cloud Based Disaster Recovery.

Available now, create a next level of redundancy by automatically backing up your audio, metadata, schedules and SQL backups directly to the Cloud. Zetta Cloud is not a Virtual Machine, but rather designed using Amazon Web services, following best practices and securities.

When a disaster strikes — be it a natural disaster like a fire or flood or a malicious cryptoware attack —users can quickly pivot to Zetta Cloud and enable the sequencer from their phone, getting your product back on the air, allowing your staff to properly assess the situation.

Meanwhile, programmers can continue to control the air product, voice track and add new audio. When the disaster has passed, disable Zetta Cloud and return to normal operations.

Shortly, users will also be able to bypass their VPN, voice track from Zetta Cloud Based Disaster Recovery and the asset will properly land in your local Zetta Library.

Between user customizations, integration, market synergy, remote workflows and embracing the future of the Cloud, it’s easy to see why Zetta is a modern, flexible, and powerful piece of radio software.
