APPLICATION: The D-RLC3 is the ideal choice where sound levels are to be controlled from a single remote

location, and where predetermined preset levels are desired.

The D-RLC3 is designed to directly interface with RDL control modules which feature a 0 to 10 Vdc control
input utilizing an external 10 k resistive control, such as the ST-VCA3, RU-VCA2A and RU-VCA6A voltage
controlled amplifiers. The D-RLC3 has four momentary pushbuttons, each corresponding to one of four levels
selected. The LEDs next to each pushbutton indicate which level is presently selected.

In a typical installation, the D-RLC3 is wired to an RDL VCA. The D-RLC3 runs from the same power
supply as the VCA. When power is applied, the D-RLC3 defaults to the NORM level. One higher level,
HIGH, and two lower levels, LOW and MIN, are then available for selection. When the D-RLC3 is
set to the HIGH position, the VCA is at maximum gain. The NORM, LOW, and MIN levels are each
adjustable by the installer using trimmers on the front of the D-RLC3. Once installed, the adjustments are
concealed from the user.

The D-RLC3 is the ideal choice in stores, meeting rooms and facilities where continuous user control of levels
is not permitted or desired. The system designer can decide how much overall boost or cut should be
available. The MIN level may be set to full attenuation, allowing the system level to be stepped the prescribed
amount above normal, below normal, or off. As supplied from RDL, HIGH is nominally 4 dB above NORM,
LOW is 4 dB below NORM, and MIN is set to off.

The D-RLC3 is constructed on a durable polycarbonate-faced, powder-coated steel panel. Electronics are
housed in a metal enclosure featuring a rear panel detachable terminal block for easy wiring. The attractive
front-panel graphics and quality construction make the D-RLC3 the ideal choice in any high quality and
economical wall-mounted remote control installation.
