The 405 is designed to remotely adjust the volume of multiple amplifiers or powered speakers, either individually or in groups. The input of the 405 is connected to a PA mixer’s line-level output (the 405 will accept the output of two mixers) and the power amps and/or powered speakers are connected to the 405’s zone outputs.
Features
- Left and right sets of balanced source 1 & 2 inputs can also accept a mono signal source
- Source 1 & 2 input channels are internally routed to the five zone channels
- Each zone channel features source 1 & 2 level controls and balanced L / R output connectors
- Stereo/mono selector button on each zone separates the L / R signals in stereo mode or combines them in mono mode, so all signals are present at both outputs
- Mono indicator LED on each zone channel
- Clip and signal LEDs on each zone channel indicate the onset of clipping distortion and signal activity
- Source 1 & 2 indicator LEDs tell you which source channel is in use
