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.

NOTE: Wiring between VCA and RLC-10R must be electrically shielded, either by installation in
a metal conduit or using shielded cable. When shielded cable is used without conduit (or in
nonmetallic conduit), the shield should be connected to the RLC-10R mounting enclosure.

NOTE: This equipment has been tested and found to
comply with the limits for a Class B digital device, pursuant
to part 15 of the FCC Rule. These limits are designed to
provide reasonable protection against harmful interference
in a residential installation. The equipment generates,
uses and can radiate radio frequency energy and, if not
installed and used in accordance with the instructions,
may cause harmful interference to radio communications.
However, there is no guarantee that interference will not
occur in a particular installation. If this equipment does
cause harmful interference to radio or television reception,
which can be determined by turning the equipment off an
on, the user is encouraged to try to correct the
interference by one or more of the following measures:
Reorient or relocate the receiving antenna
Increase the separation between the equipment
and receiver
Connect the equipment into an outlet on a circuit
different from that which the receiver is
connected.
Consult the dealer or an experienced radio/TV
technician for help.
