Using The Hp/Lp Filter.18; Using The Bass Extender.18 - Clarion APA4203 Operation & Installation Manual

Clarion APA4203/APA4I62
USING THE HP/LP FILTERS
NOTE: Clarion recommends turning the amplifier off before changing any
switch position to eliminate any possible damage from transient spikes to
the amplifier or speaker system.
1. Depending on your application, slide the FILTER CH 1/2 and FILTER
CH 3/4 switches to HP (high-pass), LP (low-pass), or OFF positions.
NOTE: If your application does not require a high-pass or low-pass
filters, slide the CH 1/2 FILTER and CH 3/4 FILTER to OFF.
2. Set the FILTER CH 1/2 and FILTER CH 3/4 controls to the
recommended crossover points from the speaker manufacturer.
3. Listen to a variety of music styles (Rock, Rap, etc.) and slightly increase
or decrease each filter control until the best performance is realized.
USING THE BASS EXTENDER
1. Initially set the BASS EXTENDER control to its full left position (i.e.,
OdB).
2. Listen to a variety of music styles (e.g., Rock, Rap, etc.) and slowly
increase the BASS EXTENDER control until a noticeable increase in
low bass response is perceived.
3. Slowly adjust the BASS EXTENDER gain control (up or down) 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.
