User manual for the RDL RU-VCA6A Digitally Controlled Six Channel Audio RU-VCA6A
The user manual for the RDL RU-VCA6A Digitally Controlled Six Channel Audio RU-VCA6A provides
necessary instructions for the proper use of the product Pro Audio - Installation Sound - System Processors.
The Radio Design Labs RU-VCA6A Digitally Controlled Six Channel Audio Attenuator is a six-channel audio attenuator module for local and/or remote control of balanced or unbalanced line-level sources. The unit has six audio channels for level control of surround sound (5.1) or six individual analog audio channels. Each module can be remote controlled from a single or multiple locations. Rear-panel terminals provide flexible control options using a variety of RDL 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. Wide-band low-noise performance makes the attenuator suited to level adjustment in the most demanding applications. Rear-panel inputs and outputs may each be wired balanced or unbalanced.
The RU-VCA6A powers up in one of two operating modes set by a rear-panel switch. In the MOM (momentary) mode, audio level is controlled by momentary pushbuttons or pulses. Remote terminals and front-panel pushbuttons are provided for up and down ramping control. If either button is held in, the audio will ramp automatically. If a button is pulsed (< 0.5 second), the audio will increment one step. The time of both the UP and DOWN ramps is individually adjustable on the front panel.
Pushing remote UP and DOWN buttons simultaneously, or pressing the front-panel GO TO PRESET button, returns the audio to a preset level. The preset level is stored by adjusting the desired level using the UP and DOWN buttons, then pressing and holding the front-panel PRESET button for 3 seconds. A rear-panel switch sets the audio power-up level to either the preset level or the last level setting used. Multiple remote control locations are possible in the MOM mode. External control pulses may be either of positive polarity or pulled-to-ground (open-collector).
In the 0 to 10 VDC mode, the preset function is disabled and the audio level is controlled by a remote 10 kΩ linear taper pot or by 0 to 10 VDC. A single remote control location is possible using a remote 10 kΩ pot.
In both operating modes, two separate 0 to 10 VDC outputs are provided. The linear RAMP output drives the level display on RDL remote controls; the EQ RAMP output is used to control an automatic RDL Loudness Equalizer. A front-panel 10-LED string display indicates the relative audio level. Control expansion is possible using the EXTERNAL CONTROL DATA jacks. One module can be set as a MASTER module to control the level of one or more additional RU-VCA2A or RU VCA6A modules set to the SLAVE mode.
The unit can be used individually, or combined with other RDL products as part of a complete system.
