Mt. Marion, NY (May 7, 2020)—Marking its 45th anniversary this year, cabling and audio interface manufacturer Sescom has introduced a plethora of new products for use in live sound, installation and house of worship settings.

The new SES-RCA-LVL-ST Stereo Single RCA Volume Control provides volume control for any device, with a passive design that provides a single level control for left & right RCA I/Os, all housed in an anodized aluminum casing. Similarly, the SES-RCA-LVL-LR Stereo Dual RCA Left / Right Volume Control does the same thing, except for dual RCA inputs to dual RCA outputs.

Sescom Bows Attenuating Line-to-Mic-Level Cables

The SES-TRRS-AB 3.5mm A/B Switch with Center Off Switch offers bidirectional, two-source audio switching or one-source audio splitting, based around three 3.5 mm female TRRS connections. The unit provides ground loop noise elimination and can be used to connect dual computers, smartphones or MP3 Players to a house system; switch line level inputs and/or outputs between amplifiers, mixers or PCs; and other uses.

Sescom’s SES-EZ-MIX-01 Two-Channel Stereo Audio Mixer with Separate Volume Control provides two 3.5 mm inputs and a single 3.5 mm output, allowing users to run multiple audio sources into one input.

Elsewhere, the SES-BUB-1206 Active 1-Channel Balanced XLR to Unbalanced RCA Audio Converter is self-explanatory, featuring an active design intended to reduce loss via its low noise, low distortion circuitry. The unit includes a power supply. For those going the other direction, there’s also the new SES-UBB-1646 Active 1-Channel Unbalanced RCA to Balanced XLR Audio Converter.

Lastly, there’s the company’s new SES-AUD-TRS-BAL Stereo Unbalanced Audio to Balanced Converter for 3.5mm TRS To Left & Right Male XLRs. The unit is not compatible with phantom powered devices.

Universal Audio Apollo x4 Interface: A Real-World Review


Universal Audio Apollo x4 Interface
Universal Audio Apollo x4 Interface, on location in St. John, U.S. Virgin Islands.

Every mobile session needs a central brain to run the show. On a recent recording trip, it was the Universal Audio Apollo x4—and that was for good reason. We won’t go into every detail of what is included; instead, I’ll talk about how we used it. Connecting to my MacBook Pro via a single Thunderbolt 3 cable, Apollo x4 includes four Unison mic preamps and two Unison Hi-Z instrument inputs. While you can have up to eight channels of additional digital input via optical ADAT/SPDIF input, we kept it simple and just used the four channels and Hi-Z inputs.

PhantomFocus System Studio Monitors Review

We connected one of the two independent headphone outputs to an external headphone amp; we used the second one for the pair of cans worn by whoever was running the laptop. It was very useful to have the Monitor button on the front, enabling access to each of the HP1 and HP2 outputs, so we could quickly change levels with the large rotary knob. By clicking a third time, “Monitor” lights up on the front panel and the rotary knob then controls the two TRS L R monitor outputs on the back, which were connected to our main monitors.

There are a few functions on the X4 that became useful during the sessions. The Preamp button on the front allows easy access to switch between CH1, CH2 and CH3/4, from which you could choose Mic or Line. There’s also a button for 48V phantom and a talkback button, which we didn’t need as we were very close to each other. We did use the dim button during playback to communicate ideas to each other (at a lower volume!).

Where the X4 really shined was during guitar and bass tracking, when we used the Unison features to dial up any number of amps, from the Marshall Plexi Classic to the Ampeg SVT VR (which are both included). Having near-zero latency is critical to me as a player, and the ability to get the feel and sponginess of the amps because they are Unison-enabled made a big difference in the quality of the parts. We also were glad to have quad-core processing because we ran a lot of plug-ins, such as the Lexicon 480L, AMS RMX16, 610B Tube Preamp and the Avalon VT737, which we used on a lot of tracks.

The Apollo X4 was undeniably a critical piece in the production chain, and the ability to have too much power and flexibility in a product with such a small footprint made it one of the stars of the show.

Radial Debuts USB-Mobile Interface/DI

Radial's USB-Mobile is a digital interface and direct box for mobile devices.
Radial’s USB-Mobile is a digital interface and direct box for mobile devices.

Vancouver, Canada (March 16, 2020)—Radial Engineering has introduced a new device, the USB-Mobile, a digital interface and direct box for mobile devices.

Radial Ships SW8-USB Switcher/Playback Interface

Usable with typical consumer mobile devices, including smartphones, tablets, and other media players, the Mobile-USB digital interface and direct box allows users to connect a device directly using a USB cable. The result is that users can provide high-quality playback, sending two channels of balanced analog outputs over XLR connectors to feed a PA system or a set of powered speakers.

The unit provides a USB-A input connector and stereo XLR outputs, as well as a level control to operate the DI in mic or line level. It also auto connects to most mobile devices.

The USB-Mobile is iOS compatible, and has the added benefit of charging the devices while they are used for audio playback. The unit is priced at $299 US.
