Set the 1X – 10X frequency multiplier switch to the setting that is appropriate for your application. A setting of
X10 will set the range of the HI-PASS crossover (FRONT) to 100–5,000Hz and the LO-PASS crossover (REAR/
SURROUND) to 500–5,000Hz.
The SLOPE switch may be set to 12dB, 24dB, or 48dB of rolloff per octave. Use this setting to adjust how
sharply the audio level increases/decreases at the crossover points.
Adjustable Subsonic Filter (SUB): The variable subsonic fi lter will provide a cut-off point for lower frequencies
(10–80Hz) that could potentially damage your speakers from over-excursion, along with wasting your amplifi er's
power. The setting for this control should be set relative to your speaker's low-frequency capability.
Output Level: Each section of the Front Row has its own OUTPUT LEVEL control. Be sure your INPUT GAIN
controls have been properly set and your crossover points selected before proceeding with this step. To properly
set the output level controls, start with the gain controls on your amplifi ers set at their lowest position and the
OUTPUT LEVEL controls on the Front Row also turned all the way down (fully counter-clockwise). With a strong
source of music playing, set your head unit's volume up to 3/4. Starting with the FRONT OUTPUT LEVEL, slowly
turn the knob clockwise until you hear your amplifi er playing very loudly, and distortion coming from your front
speakers. Turn the knob counter-clockwise slightly until the distortion is gone. Repeat this process for each
OUTPUT LEVEL section (FRONT, REAR/SURROUND, and SUBWOOFER).
If you turn the OUTPUT LEVEL control all the way up and do not get very loud output or detect distortion from
your amplifi er, then turn it all the way back down, increase the gain on your amplifi er slightly and repeat the
process. The goal is to always introduce as little gain as possible while achieving full output. This will give you the
highest possible signal-to-noise ratio for your audio system.
