SPEAKER SETUP
Selecting the SETUP menu SPEAKERS option opens the SPEAKER SETUP menu, which can be used to configure the audio output connectors for
the desired speaker setup, set speaker distances and calibrate output levels. The AV1 has eight audio output connectors labeled Front L/R, Cen-
ter, Subwoofer, Side L/R and Rear L/R.
CUSTOM SPEAKER SETUPS
Selecting the SPEAKER SETUP menu CUSTOM SETUP option opens
the CUSTOM SETUP menu, which is used to configure the audio
output connectors for a custom speaker setup. The CUSTOM
SETUP menu allows the selection of independent crossover points
for each audio output connector.
DETERMINING CROSSOVER POINTS
The CUSTOM SETUP menu allows independent crossover points to
be assigned for each audio output connector. Crossover points are
selected in 10Hz increments within a 30Hz to 120Hz range. With
the exception of THX 80Hz, all crossover points activate a 24dB
per-octave filter. The graphs on the next page indicate the fre-
quency response of these crossover points.
The THX 80Hz crossover point activates a 12dB per-octave filter for
the audio output connectors labeled Front L/R, Center, Side L/R
and Rear L/R, and a 24dB-per-octave filter for the audio output
connector labeled Subwoofer.
For each audio output connector, select the crossover point closest
to the low-frequency rating of the associated speaker. For the out-
put connector labeled Subwoofer, select the crossover point equal
to the lowest crossover point of the other speakers.
