Description
RDL RU-VCA6A - Digitally Controlled Six-Channel Audio Attenuator
The RDL RU-VCA6A is a professional studio-grade six-channel audio attenuator designed for local and remote control of balanced or unbalanced line-level signals. It is ideal for surround sound (5.1) systems or applications requiring independent control of multiple audio channels.
The RU-VCA6A provides precise 0.5 dB step adjustments using noiseless zero-crossing digital attenuators, ensuring reliable, click-free operation. Each channel features accurate level tracking, and inputs/outputs can be configured as balanced or unbalanced.
The unit operates in two selectable modes: MOM (momentary) and 0–10 VDC. MOM mode allows control via pushbuttons or pulses, with independently adjustable ramp-up and ramp-down times. In 0-10 VDC mode, level is controlled by a 10 kΩ potentiometer or voltage input. Both modes offer control outputs for level displays and loudness equalizers.
Multiple remote control points are supported, and the RU-VCA6A can function as a MASTER to control additional RU-VCA2A or RU-VCA6A modules in SLAVE mode. A front-panel LED display indicates the current audio level.
