Operating Manual - NE Multi Channel Power Amplifier
4) Pluggable Input DSP Tools - Six boxes are available for custom configuration of pluggable DSP processing
blocks. Available DSP blocks include Dynamics controls, Gain functions, Graphic and Parametric EQ, Cross
over functions, Delay, Metering, and a signal generator.
5) Input/Output Matrix Router - Any input can be routed to any or all outputs. Click and drag from the input to
output to assign routing. To delete a route, right click on the routing line and delete.
6) Output Mixer - For a given amplifier output channel, all inputs that have been routed in the matrix router are
mixed together here.
7) Pluggable Output DSP Tools - Output DSP tools are the same as those available to the inputs.
8) Output Mute Button - Mutes the output.
9) Output Channel Name - The user can name each output channel.
10) Output Channel Number - Right click on this to bring up Clear, Copy, Link, and Sub Preset functions for that
output channel.
