XO
"XO" (Crossover) allows you to apply low pass and high pass filters to the SA-
600W's outputs. This is most useful in a dedicated 2 channel system for proper
integration of your stereo satellites and subwoofer system.
The SA-600W also features individual, left and right, unbalanced RCA-type
connectors (HIGH PASS OUTPUTS) to feed a separate amplifier powering your
main stereo speakers or a second SA-600W (with Crossover set to OFF.)
OFF (default): The "High-Pass Outputs" are a buffered duplicate of the input
signal (full range). These outputs can be used to drive the inputs to another SA-
600W or other equipment.
ON: Enables selection of either a "12 dB" or "24 dB" per octave slope for the
internal filter and adjustable filter frequency (30 Hz to 130.1 Hz) using the UP
Delay
and DOWN arrow keys.

Generally speaking, the steeper slope (24 dB/octave) is preferred as this allows

As a rule of thumb, start at 80 Hz (79.9 Hz on the SA-600W) and experiment 0.0 0.0
from there. Avoid crossover frequencies below 60 Hz. Since you own a top-notch

subwoofer system, allow it to do its job and remove the low-frequency burden from

your satellites. Removing the low frequencies from your satellites will improve your
system's dynamic range and clarify the satellite's mid-range performance. Higher
crossover frequencies (above 120 Hz) can cause localization of the subwoofers due to
high-frequency bleed through.
EQ
The "EQ" (Equalizer) section gives you 3 fully-adjustable bands of equalization to
address specific in-room response problems.
OFF (default): No EQ bands are in the signal path
ON: Allows application of up to three EQ bands to the signal path. To make
adjustments, use the UP and DOWN arrows to move between parameters, and use
the LEFT and RIGHT arrows to make numerical adjustments.
Each EQ band includes the following adjustable parameter ranges:
Frequency range: 20Hz to 160Hz | Frequency step: 1Hz

Once you have saved or canceled changes, press HOME again to return to

your adjustments will be discarded (the same as if you pressed the "CANCEL
