SAT-2 Stereo Signal Attenuator
Stereo Audio Attenuator & Monitor Controller
The SAT-2? is a passive stereo audio device that provides you with a transparent level control wherever you may need it, either at the output of a pair of high-gain mic preamps, or between your recording interface and a pair of powered speakers as a compact desktop monitor controller.
Level control for a pair of powered speakers
Attenuates hot signal levels to prevent clipping
Passive audio circuit, no power required
Transparent operation without signal coloration
Ultra-quiet monitor controller
When using the SAT-2 as a monitor controller, simply connect it in between your playback device and a pair of powered speakers for an easy-access master volume control. Mute and mono switches allow you to silence the outputs or check mixes for mono phase compatibility, while a handy dim switch with adjustable level control allows you to temporarily lower the output volume without losing the main volume setting.
Attenuation in the studio
The SAT-2 can also be used to attenuate signals before sending them to your audio interface, so you can drive your mic preamps hard for coloration without clipping the inputs of the digital audio converter. A high quality 4-pole rotary knob ensures consistent L-R tracking over the entire range of the trim pot, fully maintaining the left-right balance of stereo sources.
