The black DB-RLC3 Remote Level Control, Preset Level from RDL is designed to directly interface with control modules which feature a 0 to 10 VDC control input utilizing an external 10kΩ resistive control, such as the ST-VCA3, RU-VCA2A and RU-VA6A voltage controlled amplifiers. The DB-RLC3 has four momentary push buttons, each corresponding to one of four levels selected.
In a typical installation, the DB-RLC3 is wired to a RDL VCA. The DB-RLC3 runs from the same power supply as the VCA. When power is applied, the unit defaults to the NORM level. One higher level, HIGH, and two lower levels, LOW and MIN, are then available for selection. When the device is set to the HIGH position, the VCA is at maximum gain. The NORM, LOW, and MIN levels are each adjustable using trim pots on the side of the level control. The adjustments are concealed once the unit is installed.
The DB-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.
