Caution:
When Subwoofer starts "pop" (electrical overload), please lower gain control volume and avoid the
damage to subwoofer. If the sound of subwoofer begins to produce muddiness and distortion
(amplifier allophone), please lower gain control volume, avoid that amplifier lapses into a regular
functional stop state by fault load, and wait to recover clear low-pitched sound region sensitivity.

Adjustment of an electronic crossover function (HP / LP):
Caution:
Clarion recommends turning the amplifier off before changing any switch position.
This will eliminate any possible damage from transient spikes to the amplifier or speaker system
while changing the switch setting.
(1) HP filter functional (mid-range / high region speaker correspondence) setup :
LPF/HPF control set to 125Hz is recommended. Listen to a variety of music style (Rock, Rap,
R&B, etc- -) and slowly increase or decrease the LPF/HPF control until the best performance is
realized. For most a mid range speaker, the crossover point tends to be around 100Hz. Setting
the crossover frequency too low may cause distortion is produced on a high reproduction level.
In addition to it, there is a possibility of damaging usage's speaker. If such a situation occurs,
please raise crossover frequency (please turn LPF/HPF control unit adjustment volume
clockwise), and reduce distortion.
(2) LP filter function (subwoofer correspondence) setup :
■ Speaker Level Input
When you connect with a car audio without a RCA output terminal, please use a
speaker level input terminal.
Caution:
Noise or pop sound may be made by a car audio to combine with this amplifier or by a position
of a level of gain of this amplifier.
