The DB-RLC3 is designed to directly interface
with RDL control modules which feature a 0 to 10 Vdc control input utilizing an external 10 kΩ resistive control, such as the ST-VCA3
, RU-VCA2 and RU-VCA2D voltage
controlled amplifiers. The DB-RLC3 has four momentary pushbuttons, each corresponding to one of four levels selected.
In a typical installation, the DB-RLC3 is wired to an RDL VCA
. The DB-RLC3 runs from the same power
supply as the VCA
. When power
is applied, the DB-RLC3 defaults to the NORM level
. One higher level
, HIGH, and two lower levels, LOW and MIN, are then available for selection. When the DB-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 trimpots on each side of the DB-RLC3's body. Once installed, the adjustments are concealed from the user.
