Non-crossover plugins
Two plugins provide specialized audio processing functions.
Rear/Center Channel
The
Rear/Center Channel
plugin provides a summed (L+R) or difference (L-R or R-L) signal for
use in deriving center or rear channels from a stereo signal. It also provides a 31-band graphic
EQ, high pass and low pass filters, and long delay (total 31 ms). For more information, see the
datasheet
.
Mixer
The
Mixer
plugin mixes the two input channels to the four output channels in arbitrary
combinations. Each input channel also has a 31-band graphic EQ and high pass and low pass
filters. For more information, see the
datasheet
.

Subwoofer applications
For subwoofer applications, we usually recommend the use of the
2x4 Advanced
plugin, because of its flexibility
and ability to handle many different subwoofer configurations. This flexibility is provided by the use of the
matrix mixer, which maps and mixes input channels to output channels. Here are four common subwoofer
scenarios and the recommended routing for each.
Mono subwoofer from stereo signal, and high passed speakers
In this configuration, the miniDSP Balanced 2x4 or Balanced Kit is used to generate a single mono subwoofer
feed from a stereo signal, as well as to high-pass the main speakers. The connection diagram is shown as
follows:
To accomplish this configuration, use the matrix mixer to mix input channels 1 and 2 to output 1, and to send
input 1 to output 3, and input 2 to output 4:
