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
