position. Depending on the crossover point and
slope of the source unit/processor's filter, you
may wish to engage the 500/5's sub low-pass
filter to fine-tune the sub-bass response.
• If you are using a high-quality outboard active
crossover, you can defeat all of the 500/5's filters
by selecting the “Off” position on the “Sub LP
Filter” switch in the “Subwoofer Channel
Control Section”, the “High-Pass Filter” switch
in the Rear Filter Section and the “Filter Mode”
switch in the Front Filter Section.
L-R Ambience Control:
This switch, located in the “Rear Filter Section”,
performs a very useful function when operating the
amplifier in bi-amp mode. By switching this circuit to
the “On” position, all signal common to both left
and right channels is removed from the signal
feeding the rear channels of the 500/5.When the
circuit is “On”, the rear channels will only reproduce
the extreme left and right information in the
recording, creating a realistic ambient effect from the
rear channels without detracting from the imaging
of the front speaker system. Experiment with this
switch to determine if this feature enhances the
sound of your system.

Some source units and processors with
subwoofer preamp outputs provide low-pass
filtering on these outputs, while others have a full-
range output. Consult your source unit or processor
owner's manual to determine the properties of the
subwoofer preamp output.
• If your sub preamp output is full-range, engage
the 500/5's sub low-pass filter by selecting the
“12dB” or “24dB” position on the “Sub LP
Filter” switch.This configuration is illustrated in
the setup diagram.
IMPORTANT
!
• If your sub preamp output has a choice between
full-range and low-pass modes, select the full-
range mode and use the 500/5's (likely more
sophisticated) sub low-pass filter by selecting the
“12dB” or “24dB” position on the “Sub LP
Filter” switch. This configuration is illustrated in
the setup diagram.
• If the source unit/processor sub preamp output
has a low-pass filter which is not defeatable, you
can turn the 500/5's low-pass filter off by going
to the “Subwoofer Channel Control Section” /
“Sub LP Filter” switch and selecting the “Off”

C) Two pairs of inputs connected to the rear and subwoofer inputs of the 500/5 (a source unit or processor with front and rear
outputs is required).In this mode,the source unit or processor fader adjusts the relative level of the subwoofer channel vs.all four
satellite channels as a whole.The relative level of the front and rear channels is pre-set with the amplifier input sensitivity controls
and cannot be adjusted from the source unit.
