London, UK (June 14, 2021)—Shure has introduced its new Axient Digital ADX5D Portable Receiver, expanding its flagship digital wireless line with a dual-channel, portable wireless slot receiver—a new portable form factor that makes the line more applicable to film and TV production.

While to date the Axient Digital line has been primarily used onstage in event and tour production, the new ADX5D is intended for use in sports/events broadcasting, electronic news gathering (ENG), film/episodic television, and electronic field production (EFP)—all of which rely on location sound.

The ADX5D uses true digital diversity technology, aiming to prevent signal fades and dropouts, while offering AES-256 encryption and 2 ms latency from the mic transducer to the analog output. A wide tuning band ensures reliable operation in any environment.

The ADX5D’s form factor is intended to make it an on-the-go wireless receiver, allowing it to slot inside and connect directly to the audio inputs of a professional broadcast camera. The portability is also intended to aid film and TV sound mixers who often have discrete powering, audio-routing, and/or RF-distributing gear in their portable recording bags.

ADX5D incorporates Shure’s ShowLink technology, which allows for real-time control of transmitter parameters, interference detection and avoidance. Intended for remote, hybrid, or on-location sound environments, ShowLink aids use of back-up frequencies, provides remote control directly to linked transmitters and is compatible with Shure’s Wireless Workbench software.

“The ADX5D Portable Receiver is an incredible tool to have at my disposal while on set,” said Jon Ailetcher, CAS, Production Sound Mixer on Chicago PD. “We move very fast on our show, and with ADX5D, I can easily transition from my cart to my bag, whether we’re on location or in the studio, without affecting my workflow.”

ADX5D is shipping globally this summer.

Wedemark, Germany (June 2, 2021)—Taking aim at the entry-level wireless mic market, Sennheiser has introduced its Evolution Wireless Digital series of live sound microphones, which are managed using an app-based workflow.

Aiming to simplify use and adoption of wireless mics for musicians and emerging engineers,  Evolution Wireless Digital (EW-D) offers various features that are controlled by the accompanying Smart Assist App, which guides users through system set-up. Using the app, users can create wireless connections, name channels to stay organize, and have access to all system settings. Bluetooth Low Energy allows for remote access to the system, and the app also includes tutorial videos as necessary.

Evolution Wireless Digital transmitters have an input dynamic range of 134 dB. The receiver has been set to a gain value covering most applications, according to Sennheiser, but can be changed if desired.

In terms of managing RF and conflicting signals, the Smart Assist App will scan the environment to find open frequencies. Adapting tech from Sennheiser’s Digital 6000 and Digital 9000 series, the wireless microphone systems reportedly do not generate any significant intermodulation products. This not only makes for more room in a given frequency window, but the app can also simply set the wireless links at 600 kHz intervals without any frequency calculation.

EW-D has latency of 1.9 milliseconds and a transmitter battery life of up to 12 hours with the BA 70 rechargeable battery pack. It additionally offers a bandwidth of 56 MHz with up to 90 channels per band.

EW-D handheld transmitters couple with any Sennheiser or Neumann wireless capsule.

Los Angeles, CA (May 24, 2021)—The Hallmark Channel’s Home & Family, now in its ninth season, recently upgraded to a Lectrosonics all-digital D Squared wireless mic system.

“We had been using three Lectrosonics Venue racks and SM-series transmitters since the show started in 2012,” says audio supervisor Mike Dooley, whose CV includes The Biggest Loser and The Price Is Right. “I loved how well supported they were. But when we changed rental houses, to SAV Entertainment out of Glendale, we took the opportunity to go all digital. I have to say that while the range and sound quality of the Digital Hybrid stuff was fantastic, the fully digital gear is even more amazing.”

With the RF spectrum available for TV production ever tightening, one feature that attracted Dooley’s immediate attention was the D Squared system’s built-in encryption. “NBC Universal has a frequency coordinator who assigns all our frequencies and has mostly kept us safe,” he explains. “But talent and guests wear their mics all day on this show, and of course talk privately off-set. Sometimes it’s possible that a mic is picked up somewhere it shouldn’t be. With the encryption, I no longer have to worry about that.”

“Working with a frequency coordinator also makes wideband important,” adds Joe Casanova, co-founder of SAV, along with Brady Belavek. “The DSQD receiver is tunable from 470 to 608 MHz, so there’s no need to switch out modules for different blocks if the coordinator gives you something unexpected. I’m also not aware of any other receiver that has four channels in a half-rack, which let them pack 16 channels into just two rack spaces. Between that; the Dante, Ethernet, and USB connectivity; the super low latency; and the built-in multi-coupler, the DSQD really checked all of our boxes.”

“Agreed,” Dooley replies. “With the way the DSQD uses the spectrum, Universal has been able to give us the best frequency coordination we’ve ever had.”

Dooley maintains a commanding view of the entire system’s status and performance via Lectrosonics Wireless Designer software. “I have an A2 [assistant mixer] but he’s running around and not always able to sit with the receiver rack,” he explains. “Right from the mix room, I can see the activity on all the frequencies and the transmitter battery levels in Wireless Designer. This comes in on a dedicated Ethernet port so there’s absolutely no latency in terms of the information being up-to-the-second.”

Post-Pandemic Wireless System Care: The Show Must Go ‘On’

As live events start to come back, it’s crucial to get wireless audio gear back in working order long before you need it.
As live events start to come back, it’s crucial to get every wireless system back in working order long before you need it.

When COVID-19 cases spiked last March, most people figured that we were looking at a limited shutdown—perhaps a few months. This happened just as sound companies and rental houses were preparing for the summer concert season. The global lockdown was extremely trying for everyone, and the pro audio community felt its share of the impact in 2020.

The past year has been a pretty rough time for the music industry, especially in live events. No tours, no venues, no festivals—for a full year. Now, with vaccines being distributed, live events are being tentatively planned, venues are slowly being reopened, and equipment in storage is being readied for normal use.

For most equipment, standard downtime procedures apply: Pull out that gear, dust it off, set it up, and make sure it’s sounding good and ready for action. Check your cables, lubricate wheels and hinges, tighten screws and bolts.

But while most sound companies and rental houses have solid procedures for off-season storage and reboot, one year is a long time, especially for batteries. Most of today’s wireless systems—microphones, in-ears, and intercoms—are designed for constant usage via lithium ion rechargeable batteries. The problem? No company plans for its gear to spend a full year offline.

Here’s a key fact: Even when not plugged in or powered up, all battery cells remain electrically active. That means a small, steady loss of power over time that, potentially, can affect performance. While in theory, everything should be fine, you’ll want to confirm that everything is working properly before your wireless system is back in service. So, just as you will need fresh frequency scans for your wireless systems, it’s equally important to make sure their batteries are performing properly.

Companies to Watch 2021

Many a wireless system today features advanced lithium ion rechargeable batteries. These are marvels of engineering, highly resistant to memory effects and degradation. Assuming they were stored at room temperature range, it’s unlikely there will be any issue. Still, storing batteries for a full year was never part of the plan. Fortunately, the engineers at Shure have been studying the situation.

If your battery charger offers a Storage Mode, use it! This feature charges the batteries to a slightly depleted state, optimal for long-term storage. Several Shure chargers offer this feature. For example, the AXT900 charger can put the batteries in storage mode. This puts the voltage of the battery at a mid-range point (3.8 volts), which is best for the battery.

Also, keep the battery from getting too hot or too cold. Lithium ion batteries can lose health when stored in cold or hot areas. For best performance, store the batteries in normal room temperatures.

If you haven’t used your rechargeable batteries in a while, don’t wait; do the following now: Put your lithium ion batteries through several power cycles—at least two—before being returned to routine service. This serves to physically demonstrate the run time while simultaneously stabilizing the electrochemical properties of the batteries. Please review your owner’s manual and documentation and follow all other safety recommendations for handling lithium ion batteries. If your battery fails to charge after the power cycles, contact the manufacturer for further guidelines.

We’re all excited at the prospect of the live events industry working again. At the same time, we urge everyone to be patient, stay safe, and follow appropriate protocols.

Shure Petitions FCC for Dedicated Wireless Mic Channel

FCCChicago, IL (February 4, 2021)—In recent years, RF audio pros have faced increasing difficulties as the amount of usable spectrum available to wireless microphones has steadily vanished—first in 2010 as the FCC bumped pro audio out of the 700 MHz band (roughly 698-806 MHz) requisitioning that range for the use of public safety, and then again in 2017, as it auctioned off most of the 600 MHz service band (617-652 MHz and 663-698 MHz). While the FCC some conciliatory stabs at ensuring space for wireless audio gear were made at the time, those rulings recently fell by the wayside, and now wireless mic manufacturer Shure has petitioned the FCC to reverse its recent decision and ensure that at least one “vacant” 6 MHz UHF channel is designated in each market for wireless microphone use.

The petition comes just weeks after longtime FCC Chairman Ajit Pai stepped down on January 20 as President Biden was inaugurated (Jessica Rosenworcel has since been appointed acting FCC chair). Pai’s occasionally contentious stint atop the FCC began in 2012; among the last events taking place under his stewardship, in early December, 2020, the FCC terminated the “Vacant Channels” rulemaking that was opened during the 600 MHz incentive auction and declined to authorize a dedicated UHF TV channel for wireless microphone use. Shure disagrees with the FCC conclusions and rationale for terminating the proceeding and has asked the Commission to reverse the decision.

Shure’s petition argues the wireless microphone community needs clear spectrum now more than ever, as the 600 MHz band has been reallocated to mobile phone use and the DTV repack has moved many TV stations into the 500 MHz spectrum. At the same time, broadcast, performance and sporting productions continue to demand more channels of wireless microphones than ever before.

According to Shure, the “alternative” frequencies identified by the FCC in 2017 for wireless microphone use at 900 MHz, 1.4 GHz, and 7 GHz fall short of addressing the needs of wireless microphone users, as they are less flexible than UHF frequencies. Because these bands are occupied by licensed users in other industries, access to these bands for wireless microphone use is conditioned on sharing requests, which can be lengthy and ultimately denied.

The company noted that ensuring the presence of at least one dedicated channel in a market is important to meet demand for wireless microphone use, and that channel would also be important for applications that include intercom, IFB and others.

“The amount of available UHF spectrum for wireless microphone use continues to shrink,” said Ahren Hartman, vice president, Corporate Quality, Shure. “With the loss of 700 MHz, 600 MHz, and the DTV repack into 500 MHz, we are at an all-time low for access to UHF spectrum. However, the need for open and clear wireless microphone spectrum is higher than ever before.”

The petition marks one of Shure’s first forays back into lobbying following the unexpected death last October of longtime Shure executive Mark Brunner, VP of Global Corporate & Government Relations. Brunner previously led the company’s lobbying efforts in Washington D.C. to promote industry interests in wireless device regulation, frequency spectrum allocation and more.

FCC Announces Repack Complete, Spectrum Open for Wireless

T-Mobile purchased the 600 MHz space at auction in June, 2017 for nearly $8 billion, and wasted no time taking over the spectrum, lighting up its first network site, seen here, in Cheyenne, WY barely two months later.

Washington, DC (July 15, 2020)—After 39 months, the FCC has announced that the post-incentive auction transition, which saw many TV stations take part in the repack from their pre-auction channels, has been successfully completed. As of July 13, the 600 MHz spectrum, which numerous models of wireless RF microphones and other pro audio devices were allowed to operate within before the auction, has officially been vacated. The spectrum that was sold during the broadcast incentive auction is now available for use by wireless mobile broadband services.

Can RF Mics Be Harmonized Globally?

The announcement came 10 days after phase 10 of the repack was scheduled to conclude on July 3. During the repack, 987 full-power and Class A TV stations were reassigned to new TV channels. To date, the commission says that 99% of those stations have successfully transitioned; those that have not yet made the move were granted short extensions due to unforeseen circumstances, but are still scheduled to complete the repack by the end of the summer. These remaining stations are currently located in the portion of the band allocated for broadcast TV or the duplex gap, and none are expected to delay the deployment of wireless services in the 600 MHz band.

The FCC will continue to work with stations on distributing their reimbursements for relocation expenses from the $2.75 billion TV Broadcaster Relocation Fund.

With the now-available spectrum, the FCC says millions of Americans will benefit as the allotment will now be used for the development and promotion of 5G, to help close the digital divide in rural America, ease congestion on wireless networks and spur job creation and economic growth.

“Today represents a milestone in the commission’s effort to repurpose spectrum to meet the demands of wireless consumers,” said FCC Chairman Ajit Pai. “I want to thank the broadcast and wireless industries, the tower crews, the equipment manufacturers and the radio frequency engineers who support them for the hard work they have done over the past 39 months to make the benefits of the broadcast incentive auction a reality.”

The National Association of Broadcasters’ President and CEO Gordon Smith also provided a statement on the official end of the repack: “I am incredibly proud of the broadcast television industry for its herculean efforts to meet the FCC’s aggressive repacking deadlines, despite complex and extenuating circumstances.

“NAB thanks the FCC staff for their flexibility in working with stations to facilitate transitions and grant extensions when possible. We are also grateful to Congress for allocating the additional funds needed to fully reimburse broadcasters for costs associated with these mandatory moves.

“There is still much work to be done. To meet FCC deadlines, many stations have been required to operate on temporary facilities that do not serve all station viewers. NAB will continue to work with the FCC to ensure that these stations are made whole and that affected viewers regain access to their local channels. In this uncertain time, it is vital that TV viewers have access to local news, entertainment and lifeline information.”
