Sound Devices Unveils A20-RX Wireless Receiver With SpectraBand Technology

Sound Devices A20-RX propped on a rock.Reedsburg, Wisc.-based Sound Devices announced the shipping of the A20-RX. Per the company, it is a two channel, true diversity receiver with industry-exclusive SpectraBand technology. SpectraBand gives the A20-RX receiver and A20-Mini transmitter an expansive tuning range: 470 MHz – 1525 MHz. The A20-RX also features high-discrimination front end filtering for better performance in noisy RF environments. Moreover, it has Frequency AutoAssign for faster setup.

Upgrade Program

The receiver is compatible with both A20-Mini and A10-TX transmitters. Sound professionals with the previous model, A10-RX, can upgrade the hardware of their receivers to the A20-RX for $995. Or they can go for a reduced price of $750 if they purchased their A10-RX within the last 12 months or an A20-Mini since June 1, 2022. The upgrade program lasts until the end of 2022.

“As wireless spectrum becomes increasingly crowded, sound professionals need flexibility when it comes to tuning range. The A20-RX is the first receiver on the market that can tune not only in common UHF TV bands around 470 – 608 MHz, but far above that,” said Gary Trenda, RF applications engineer at Sound Devices. “We’re excited to offer the A20-RX and an upgrade path for our A10-RX customers.”

Features of A20-RX

SpectraBand eliminates the need for purchasing different wireless receivers dedicated to specific frequency bands, the company adds. In the U.S., the A20-RX can tune to the 600 MHz guard band (614-616 MHz), 600 MHz duplex gap (653-663 MHz), 900 MHz ISM Band (902-928MHz), 900 MHz STL Band (941.5-960 MHz), and, with the appropriate license, the 1.5 GHz AFTRCC band (1435-1525 MHz). This is in addition to the core USA UHF TV band from 470-608 MHz that’s commonly available. Overall, this totals approximately 285 MHz of available spectrum.

The A20-RX is the second product in Sound Devices’ first wireless product line. The first product, the A20-Mini transmitter, is receiving a free firmware upgrade to enable SpectraBand when used with the A20-RX. The A20-RX is also compatible with all tuning ranges of the full-size A10-TX and is SuperSlot compatible with an SL-2 SuperSlot Wireless Module and 8-Series mixer-recorder.

Two other notable features of the A20-RX are its front-end filtering and Frequency AutoAssign. While tracking filters are common in wireless receivers, the A20-RX uses superior low-loss, brick-wall SAW filters to deliver excellent performance in noisy RF environments. These built-in filters also provide excellent immunity from nearby IFB or camera hop transmitters without the need for external filters or extra cabling.

The AutoAssign feature scans a user-designated tuning band and selects available frequencies for the A20-RX’s two channels. This feature is designed to make frequency selection and setting quick and easy.

Per a statement, the release of the A20-RX coincides with supporting firmware for the A20-Mini, A10-TX, 8-Series, SD-Utility and A20-Remote.

Audiovisual Projects

When Advanced Medical Transport (AMT) wanted to build a new simulation and training center at its Peoria-based headquarters, the provider of emergency and scheduled ambulance services in Central and Western Illinois selected Pearl Technology to provide the new state-of-the-art facilities audiovisual components. Pearl Technology, a custom audiovisual integration technology and services company, realized it needed miniature and flexible cameras for operation. Thus, it selected the CV630-IP PTZ and CV503 Miniature Full-HD cameras from Marshall Electronics. Marshall is of course, the Torrance, Calif.-based manufacturer of broadcast and pro AV cameras and equipment.

This provides instructors, EMTs and trainees the opportunity to develop and practice physical skills, critical thinking, decision-making, collaboration and communication in a safe yet realistic environment.

The new facility also allows for the dedicated recording and playback of all audio and video and can also stream the simulations in a live environment. The space features four spaces. All rooms now have Marshall cameras, hidden microphones to capture room audio and in-ceiling speakers to allow for paging from the control room back into the small simulation room.

Choosing the Right Setup

For Jeremy Caldera, senior vice president, Audiovisual Solutions, Pearl Technology, the decision to go with Marshall was based on previous experience. “I selected Marshall because I’ve done other medical simulation facilities over the years using their cameras and the results have been great. The Marshall cameras have always exceeded our expectations with crisp, clear pictures,” says Caldera. “I’m a big fan of their products. The versatility of the miniature and PTZ cameras allows me to have a lot of flexibility in the space. The ability to have multiple control stations with multiple Marshall PTZ controllers helps as well.”

Marshall Cameras perched in corner of ambulance.The new training center includes four simulation areas (three rooms and an ambulance simulation space). It also has one main control room with transmission of audio and video to two remote spaces. Two smaller simulation rooms each have one CV630-IP PTZ camera mounted in the far corner of the room. Thus, it is not obtrusive to the environment. These two rooms also have one CV503 fixed ceiling camera respectively.

Capturing all Angles

The facilities’ larger simulation room features two CV630-IP PTZ cameras to capture detailed images from different angles. The room has a 75-inch flat panel display mounted on the wall showing video from the CV630-IP cameras throughout the simulation space. The ambulance simulation area includes two CV503’s mounted in the far corners of the ambulance. This provides the ability to capture the interior of the emergency services vehicle.

Monitors displaying feed from AMT facility rooms.In addition to the simulation rooms, Pearl Technology created a control room with three workstations. Each workstation includes a Marshall VS-PTC-IP PTZ camera controller allowing for remote operation from the CV630-IP PTZ in each respective room. The VS-PTC-IP camera controller is designed to operate seamlessly across multiple camera protocols on a single network.

“I have been very pleased with the versatility of the Marshall cameras and how easily they integrate into the most basic or advanced systems designs,” adds Caldera. “The quality of the image produced by these cameras at their price point is very impressive. Marshall is always great to work with.”
