DESCRIPnON
The Clanon APX400.4 4-channel car audio amplifier
IS
an excellent choice for
creatmg a vanety
of
multi-channel sound systems.
It
features built-m system
deSign flexibility that allows you to create a 2, 3 or 4 channel amplifier
With
a
flip
of
a sWitch.
You
can also configure the front or rear amplifier sectIOns for a
mixed mode operatIOn to dnve a set
of
satellite speakers and/or subwoofer.
The built-m
12
dB per octave electrOnIc crossover lets you custom tailor the
sound
of
the front and rear channels, usmg two mdependent filters
With
adjustable crossover frequencies for high-pass or low-pass filtermg.
The amplifier also uses an unregulated MOSFET power supply for supenor
control
of
output wattage. A torOid-coil transformer yields maximum power
transfer
With
minImum heat loss. Careful
CirCUit
deSign keeps AM RFI at low
levels, so you
won't
hear unwanted
nOise

IS
cranked up.
ProtectIOn
CirCUits
safeguard the amplifier when overheatmg and speaker shorts
or Improper load conditIOns occur.
All connections and controls are on the end panels and are easy to understand.
We
use gold-plated RCA and

connectors to ensure the best electncal
connectIOn for your system. Included are external automotive type fuses that
