Built-in Crossover
The California amplifiers include a built-in variable **high and low pass crossovers. The
crossover features a variable frequency selection of (80 Hz ~ 1.2k Hz) for precise high pass
filter and (50 Hz ~ 250 Hz) for low pass filter.
** AP2000, AP700M, and AP1000M models only have a 50 Hz ~ 250 Hz low pass filter.

EATURES AND BENEFITS
Treble Boost
For added high frequency performance two 4 channel amplifier models, AP740 & AP1040,
are equipped with a variable 0~12 dB treble boost @ 8k Hz on channels 1 & 2.
Bass Level Remote Control
Models AP1200, AP2000, AP700M, and AP1000M are equipped with a wired (16.4 ft.) bass
level remote control that can be mounted under dash to remotely control the level of the
bass.
Subsonic Filter
Models AP2000, AP700M, and AP1000M are equipped with a variable 20~50 Hz subsonic
filter. This filter avoids the reproduction of inaudible low frequencies on the amplifier
which could damage the subwoofers because they can generate over-displacement of the
subwoofer cone.
Phase Control
Mono subwoofer amplifier models, AP700M and AP1000M, are equipped with a continuously
adjustable phase lag control on the subwoofer(s) from 0 to 180 degrees.
This control helps to align the phase shift of a subwoofer for a smooth blending.
Bass Boost
For added low frequency performance the amplifiers are equipped with a variable 0~12 dB
bass boost @ 45Hz.
External High To Low Level Converter
This adapter converts high (speaker) level signal to low (RCA) level and used when installing
an amplifier to a factory radio without pre-amp (RCA) output.
