An interview from the 2022 NAB Show New York with Greg Boren of Marshall Electronics. Marshall Broadcast & AV is a globally recognized and award-winning brand for providing high performance and reliable products for live broadcast TV, integrated AV, and cinema production.

The Marshall AR-DM5-1B is a digital audio monitor designed for news vans, remote OB vans, equipment rooms, and more. It sports multiple input types for video and audio, including HDMI and 3G SDI with looping output.

Audio connections are possible via balanced or unbalanced connections. For balanced connections, use the XLR jacks; unbalanced terminations are handled by RCA stereo I/O. You can output audio digitally via XLR jacks carrying the AES/EBU format, or make use of the unbalanced RCA line-level outputs for analog.

In addition to stereo level metering, the unit provides a 2" video monitor, which can offer confidence images of selected HDMI or SDI sources. You'll also note the text overlay that displays the input source, the selected audio channels, and the source video parameter. A 3.5mm headphone jack for private monitoring is found on the front panel, where you'll also find control buttons for left, right, mute, solo, input, and mix down, as well as a volume/mute knob.
On the rear of the device you'll find all your connections. These include an HDMI in, a 9-pin D-sub input for RS-232 serial control, an Ethernet RJ45 port, SDI input and loop out, XLR I/O (both analog and AES/EBU), and RCA jacks.

The AR-DM51-B's 1 RU construction is designed to save space, packing features found in many 2 RU units into a smaller sizer. The device is controllable via Ethernet or RS-232, with a control application downloadable from Marshall's website.

The Marshall Electronics AR-DM61-BT-64DT is an active, multichannel rackmount digital audio monitoring system in a 1-RU chassis featuring a 10" LCD touchscreen. This configuration includes a pre-installed 64-channel Dante module for digital audio networking. The system is ready for installation in tight spaces in TV stations, broadcast trucks, house-of-worship facilities, and transfer stations where powerful monitoring is required.

The front panel features high-powered stereo speakers, capable of 100 dB output levels, along with a 1/4" headphone jack, volume control, and the full-color LCD touchscreen. The touchscreen displays up to 64 channels vertically or can be switched to 96-step, high-precision horizontal bars; it also offers a live video preview monitor.

On the back of the AR-DM61-BT-64DT are two dedicated, MADI-compatible 3G-SDI inputs with loop-through, four AES stereo inputs and outputs on D-sub connectors as well as eight analog inputs and outputs on D-sub connectors. Two RJ45 ports support Ethernet networking. The included 64-channel Dante module adds two additional RJ45 ports for Dante A&B networks.
