A properly setup Home Theater Surround Sound System
should have all Loudspeaker levels adjusted to the same
starting reference volume level in the Listening/Viewing
Area. The MX134 includes a built-in test signal generator,
which can have its output switched into each Loudspeaker,
either automatically or manually. The desired test signal
volume levels of each Loudspeaker can be determined, in
the Listening/Viewing area, either by listening or with a
sound pressure meter. Level adjustments are made in 1dB
steps by using the MX134 Remote Control Left
and
Right
Directional Push-buttons. The level can be ad-
justed over a plus or minus 12dB range.
Notes: Before adjusting the SPEAKER LEVELs, you FIRST
must have performed the SPEAKER SIZE and

aid in adjusting the Loudspeaker levels.
