Crossover Frequency Setting
Small speakers cannot reproduce the bass sound very well. So, if
you have used a small speaker for any of the front, center, and rear
channels, this receiver automatically reallocate the bass elements,
originally assigned to the channel for which you have connected the
small speaker, to another channel (for which you have connected the
large speaker).
To use this function properly, you need to set the crossover
frequency level according to the size of the small speaker connected.
• If you have selected "LARGE" for all speakers (see page 24), this
function is set to "OFF" and cannot be adjusted.
On the front panel ONLY:
1. Press SETTING repeatedly until
"CROSSOVER FRQ" (Crossover
Frequency) appears on the display.
The display changes to show the current setting.
2. Turn MULTI JOG to select the
crossover frequency level
according to the size of the small
speaker connected.
• As you turn it, the display changes to show the following:
80Hz 100Hz
• Use the following comments as reference when adjusting.
80Hz: Select this when the cone speaker unit built in the
speaker is about 4
100Hz: Select this when the cone speaker unit built in the

120Hz: Select this when the cone speaker unit built in the
speaker is about 3
