The RLC-10R is part of the group of remote control accessories from Radio Design Labs. The rugged high quality
construction and professional styling make the RLC-10R the optimum choice for level control in critical high quality
installations.
APPLICATION: The RLC-10R is the ideal choice for 0 to 10 Vdc or pulsed control from a remote location. Control is
based on optical encoder technology to produce long-term trouble-free operation.
Two output modes are simultaneously available. The 0 to 10 Vdc output operates continuously. Up and down pulses
from the optical encoder are also provided on the rear barrier block. The 0 to 10 V output is used to control RDL VCA
products, and may be connected to a wide range of other industry 0 to 10 Vdc controlled equipment. This mode is used
for single point control. If multiple control points are desired, the pulse outputs may be connected to RDL RU-VCA
products and various other industry products. A rear-panel jumper sets the PULSE outputs to either produce +15 Vdc
pulses or momentary open collector pulses.
Control is incremented up or down when the large front-panel knob is rotated. Acceleration is provided so the rate of
change is faster when the knob is rotated more rapidly, yielding a responsive feel.
The LED ring display encircling the control knob operates as a virtual pointer. The input to this display is a 0 to 10 Vdc
signal. A strap on the module rear barrier block determines if the display operates from the internally generated control
voltage or from an external control voltage. Typically, if the 0 to 10 Vdc control voltage from the RLC-10R is being used to
control a VCA, the internal voltage is also used for the display. If the RLC-10R pulse outputs are used with RDL RU-VCA
modules, the 0 to 10 Vdc EQRAMP from the VCA module is fed back to the RLC-10R. Therefore, multiple RLC-10R
modules may be connected together with all modules providing the same level indication.
In the event of power loss, internal non-volatile memory stores the last level value. When power returns, the 0 to 10 V
output will return to the operating level present when power was lost.
Wherever the highest quality, durability, performance and appearance are required in remote level control, the
RLC-10R is the ideal choice. Use the RLC-10R individually, or combine it with other RDL products as part of a complete
audio/video system.
