Radial Engineering SAT-2 & MIX 2:1 Studio Tools By Adam Gallant T SAT-2 Stereo Audio Attenuator & Monitor Controller he SAT-2 by Radial Engineering is designed primarily as a studio monitor controller to connect between your audio interface and powered studio speakers; however, its simple design gives this box a whole host of other, equally useful applications. I’ll run down a few features then give examples of how we put it to use in our studio. Like all of Radial’s products, this unit is robust enough for use on the road and built to last a lifetime. The case is built from 14-gauge solid steel with a lip that protects the front panel switches from damage. The finish is a quality glossy black and very clearly labeled. The back panel features both TRS and XLR inputs as well as XLR outputs. The front panel consists of a mono switch, mute switch, volume knob, and a DIM switch with adjustable level control. When I’m mixing, I like to avoid touching the playback volume as much as possible. Having the master volume remain constant by using the DIM switch for checking at low levels has allowed my ears to trust a certain volume threshold, which has been great for bringing in new elements to a working mix. The DIM level control is also recessed to avoid accidental adjustment. The SAT-2 is completely passive, requiring no power source and offering a transparent sound. As a studio monitor controller, the SAT-2 is zero fuss and much cleaner sounding than the small-format mixer I’m used to using. The SAT-2’s volume knob is of high quality and ensures consistent left to right tracking over the entire range of the trim pot. With lower quality trim pots on stereo material, you’ll often find a slight pan to one side as you attenuate; the SAT-2 is void of this issue, offering a consistent stereo image all the way down to zero volume. The mute, mono, and DIM switches are silent as well. As a simple volume attenuator, the SAT-2 can solve a lot of gain staging challenges. We have a pair of the traditional API 512c pre- amps at our studio and they are often run at a very safe input level to avoid clipping the input side of our interface’s A to D converters. The SAT-2 can be added to the output of any preamp to attenu- ate the signal, allowing for colouration of the microphone preamp’s input while keeping within safe limits on the interface side. Hearing the APIs driven for the first time was great and I suspect tube pre- amps would be given an extra level of versatility with the attenua- tor in the chain. MIX 2:1 Two-Channel Audio Combiner & Mixer The MIX 2:1 by Radial is a two-channel passive mixer that essentially allows you to take two mono sources and sum them to one mono signal with clarity and detail.
