The Lectrosonics RCWPB4 is a compact and intuitive wallplate control interface designed specifically for use with Lectrosonics DM Series processors. Housed in a durable stainless steel faceplate, it provides users with a convenient way to trigger remote control operations such as launching macros or recalling presets. With four clearly labeled push buttons and corresponding LEDs, the RCWPB4 allows for immediate visual feedback—each button press activates a command on the processor and lights up the associated LED to indicate the current state. This streamlined design is ideal for setups requiring quick and reliable changes, like room combining or event presets. Installation is straightforward, with the unit connecting via a 25-pin D-sub connector to the back of a DM Series processor. Each button on the wallplate sends a pulse to the processor, while the LED remains lit until a different button is pressed, serving as a real-time state indicator. The RCWPB4 also offers flexibility for more advanced configurations: certain LEDs (specifically LED 1 and LED 3) can be controlled directly by the DM processor instead of the button press. This allows the system to display status indicators for processor-driven events—ideal for complex automation scenarios like macros or dynamic room configurations.
