Figure 8. Use this chart to find a copper-wire gauge that will exhibit no
more
than a 0.5 volt drop for a desired cable length . If aluminum or
tinned wire is used, select an even larger gauge size to compensate for
material difference. NOTE: Cable-size calculations take into account
,, terminal connection resistance.
SETTING GAIN
After completing the installation, follow these steps to set the amplifier's
GAIN control:
1. Tum GAIN and BASS EXTENDER controls full left to their
minimum positions. Set FILTER to OFF .
2. Tum the vehicle 's ignition switch to the ON position. Then tum on the
source unit. Set all tone or equalization controls to "flat" po s itions and
tum loudness off.
3. Play a CD or tape and set the volume control at 75 % of full level.
4. Verify that the POWER indicator on the amplifier comes on .
NOTE: When using an equalizer, set its frequency controls
to"flat."
5. If appropriate, set the fader control (on the source unit) to feed the
amplifier at full level. Slowly increase the GAIN. Stop when you hear a
slight distortion of
audio.

USING THE HP /LP FILTER
NOTE: Clarion recommends turning the amplifi er r4/ I e, /(Jre clWllMillf{ mt
switch position to eliminate any possible darna ge Jimn trr111sie111 .1· 1,ik e. 1· to
the amplifier or speaker system.
1. Depending on your application , slide the FILTER swilch lo HP (high -
pass) or LP (low-pass).
NOTE: If your application does not require a high - pass or low - pass filter,
slide the FILTER switch to OFF
2. Set the FREQ control set to the recommended crossover point from the
speaker manufacturer.
3. Listen to a variety of music styles (Rock, Rap, etc.) and sl ightly i. ncr ease
or decrease the FREQ control until the best performance is realized.
USING THE BASS EXTENDER
1. Initially set the BASS EXTENDER control to its full left posilion (i.e.,
OdB).
2. Listen to a variety of music styles (e .g., Rock, Rap, etc.) and s lowly
increase the BASS EXTENDER control until a noticeable incr ase in
low bass response is perceived.
3. Slowly adjust the BASS EXTENDER gain control (up or d wn) to
realize the best bass response.
CAUTION: If you hear a "pop" (due to speaker over - excursion), lower
the BASS EXTENDER to prevent speaker damage. If the system sounds
muddy and distorted (due to amplifier clipping), lower BASS
EXTENDER to avoid shutdown from overheating.
