The RDL RU-VCA2A 2-Channel Digitally Controlled Attenuator is a full-featured, studio-quality, dual-channel audio attenuator module for local and/or remote control of balanced or unbalanced line-level sources. This module can be remote controlled from a single or multiple locations. Rear-panel terminals provide flexible control options using a variety of remote controls or OEM equipment.
Audio levels are controlled in 0.5 dB steps using noiseless, zero-crossing digital attenuators for optimum reliability, precise tracking, and long-term, click-free service. Exceptional wide-band, low-noise performance makes this attenuator suited to level adjustment in demanding applications. Rear-panel inputs and outputs may each be wired balanced or unbalanced. The RU-VCA2A Attenuator powers up in one of 2 operating modes (MOM and 0 to 10VDC modes) set by a rear-panel switch.
