{"product_id":"rdl-ru-vca6a","title":"RDL RU-VCA6A","description":"\u003ch3\u003eOverview\u003c\/h3\u003e\u003cp\u003eThe RU-VCA6A is a full-featured studio-quality six-channel audio attenuator module for local and\/or remote control of balanced or unbalanced line-level sources. The RU-VCA6A 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.\u003c\/p\u003e\u003cp\u003eAudio 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 the RU VCA6A suited to level adjustment in the most demanding applications. Rear-panel inputs and outputs may each be wired balanced or unbalanced.\u003c\/p\u003e\u003cp\u003eThe RU-VCA6A powers up in one of two operating modes set by a rear-panel switch.\u003c\/p\u003e\u003cp\u003e\u003cu\u003eMOM (momentary) Mode\u003c\/u\u003e\u003c\/p\u003e\u003cp\u003eIn the \u003cstrong\u003eMOM\u003c\/strong\u003e (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 (\u0026lt; 0.5 second), the audio will increment one step. The time of both the \u003cstrong\u003eUP\u003c\/strong\u003e and \u003cstrong\u003eDOWN\u003c\/strong\u003e ramps is individually adjustable on the front panel. Pushing remote \u003cstrong\u003eUP\u003c\/strong\u003e and \u003cstrong\u003eDOWN\u003c\/strong\u003e buttons simultaneously, or pressing the front-panel \u003cstrong\u003eGO TO PRESET\u003c\/strong\u003e 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 \u003cstrong\u003ePRESET\u003c\/strong\u003e 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).\u003c\/p\u003e\u003cp\u003e\u003cu\u003e0 to 10 VDC Mode\u003c\/u\u003e\u003c\/p\u003e\u003cp\u003eIn the \u003cstrong\u003e0 to 10 VDC\u003c\/strong\u003e mode the preset function is disabled and the audio level is controlled by a remote 10 k? linear taper pot or by 0 to 10 Vdc. A single remote control location is possible using a remote 10 k? pot.\u003c\/p\u003e\u003cp\u003eIn both operating modes, two separate 0 to 10 Vdc outputs are provided. The linear \u003cstrong\u003eRAMP\u003c\/strong\u003e output drives the level display on RDL remote controls; the \u003cstrong\u003eEQ RAMP\u003c\/strong\u003e output is used to control an automatic RDL Loudness Equalizer (see ST LEQ1). A front-panel 10-LED string display indicates the relative audio level. Control expansion is possible using the \u003cstrong\u003eEXTERNAL CONTROL DATA\u003c\/strong\u003e jacks. One module can be set as a \u003cstrong\u003eMASTER\u003c\/strong\u003e module to control the level of one or more additional RU-VCA2A or RU VCA6A modules set to the SLAVE mode.\u003c\/p\u003e\u003cp\u003eUse the RU-VCA6A individually, or combine it with other RDL products as part of a complete system.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eLocal or Remote Audio Level Control\u003c\/li\u003e\n\u003cli\u003eSix Channel \/ Surround Attenuation\u003c\/li\u003e\n\u003cli\u003eNoiseless Zero-Crossing Adjustment Steps\u003c\/li\u003e\n\u003cli\u003e96 dB Attenuation Range in 0.5 dB Steps\u003c\/li\u003e\n\u003cli\u003eData Bus Provides Adjustment of Multiple Modules \u003c\/li\u003e\n\u003cli\u003eMultiple Remote Control Locations Possible\u003c\/li\u003e\n\u003cli\u003ePrecise Level Tracking on Each Channel\u003c\/li\u003e\n\u003cli\u003eBalanced or Unbalanced Line Inputs\/Outputs\u003c\/li\u003e\n\u003cli\u003eAdjustable Ramp Up\/Down Rates\u003c\/li\u003e\n\u003cli\u003eControllable Using Various RDL Remote Controls\u003c\/li\u003e\n\u003cli\u003eSelectable Level Control Options:\u003cbr\u003e    Pushbuttons (Internal or External)\u003cbr\u003e    Momentary Pulses (External\/Rotary Encoder)\u003cbr\u003e    0 to10 Vdc or 10 kΩ Potentiometer\u003c\/li\u003e\n\u003cli\u003eSelectable Power-Up Return to PRESET or LAST Level\u003c\/li\u003e\n\u003cli\u003eSelectable MASTER\/SLAVE Mode for Control Expansion\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable class=\"table1\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eInputs (6)\u003c\/td\u003e\n\u003ctd\u003e\u0026gt;10 k?
