The D-RLC2 is the ideal choice where levels are to be controlled from a single, or from multiple control locations, and visual level indication is desired.The D-RLC2 is designed to directly interface with RDL control modules, such as the STICK-ON® series ST-RG1 Ramp Generator, or RACK-UP® series RU-VCA2A Digitally Controlled Audio Attenuator. The D-RLC2 has two momentary pushbuttons, UP and DOWN. Pushing each button sends the appropriate signal back to the RDL control module. When connected to the RU-VCA2A, pushing both buttons on the D-RLC2 simultaneously causes the level to return to the PRESET level on the RU-VCA2A.In installations where ULTRASTYLE™ wall controls are preferred, use the RLC-10R Rotary Level Control.
