5.1 SPEAKER SETUP

If a source component, such as a Blu-ray player or media streamer, also offers bass management and time alignment,
be sure to disable the source device's built-in bass management and time alignment. Do this by setting all channels to
"large" and setting identical values for distance to the listener (your source doesn't need to handle these settings
since the MRX/AVM performs these tasks). Performing these processes twice will degrade audio quality.

Amp Matrixing
This option allows you to assign amplifier channels to different channels of information. This is meant to allow you to
replace certain amp channels with external amplification and still be able to use the amplifier channels to power other
speakers, for example it is common to use an external amplifier to power the Front Left and Front Right speakers if
they require more power, you can use this menu to assign the amplifier channels originally used for these speakers to
power other speakers such as Height or Zone 2. The Centre channel cannot be reassigned because it is a single
channel while everything else is a pair.
Bi-Amp
This option allows you to use unused channels to apply extra amplification to your front speakers, this should only be
used if your front speakers have the connections that allow bi-amping. Bi-amping is useful for separating the high-
frequencies on a speaker from the low-frequencies, this is especially useful if there is any audible distortion in the
bass section. Note that bi-amping does not "double" the power to the speaker, it applies the same amount to your
speaker in two different areas.
Zone 2 on Demand
When "Zone 2 on Demand" is ON then Back speakers will be set to Zone 2 when Zone 2 is powered on, when Zone 2
is powered off, the Back speakers will revert to their option chosen in the Amp Matrixing menu. When "Zone 2 on
Demand" is OFF, the Back speakers will follow the Amp Matrixing selection always.
