Design Features
1. Cast Aluminum Heatsink The cast aluminum heatsink of the Power amplifier
dissipates heat generated by the amplifier's circuitry. The inherent advantage of
casting provides a 30% improvement of cooling over conventional extrusion
heatsink designs.
2. Speaker/Power Terminals The heavy duty, gold-plated terminal block con-
nectors (+ and ) will accept 4 gauge cable and are immune to corrosion that
can cause signal degradation.
3. REM Terminal This spade terminal is used to remotely turn on and turn off the
amplifier when +12V DC is applied.
4. Signal Input Switch (Power 400, Power 800 4-channel & 600 5channel
amplifiers)
This switch allows the amplifier to be driven with either 2 or 4
pairs of inputs.
5. RCA Input Jacks The industry standard RCA jacks provide an easy connection
for signal level input. They are gold-plated to resist the signal degradation
caused by corrosion.
6. RCA Pass-Thru Jacks The Pass-Thru provides a convenient source for daisy-
chaining an additional amplifier without running an extra set of RCA cables
from the front of the vehicle to the rear amplifier location.
7. Gain Control The input gain control is preset to match the output of most
source units. It can be adjusted to match output levels from a variety of source
units.
8. Remote Punch Bass The Punch Bass helps correct for acoustical deficiencies
in the listening environment by helping reproduce full range sound without
adding excessive boost. The Punch Bass control is a narrow band adjustment
centered at 45Hz variable from 0dB to +18dB. Connection is made with a
cable using RJ-45 and can be installed under the dash for remote control access.
9. Internal Crossover The internal crossover is a 24dB/octave Butterworth filter
selectable for High-Pass (HP), Full Range (FULL), or Low-Pass (LP) operation
variable from 50Hz to 210Hz.
10. LED Power Indicator The LED illuminates when the unit is turned on.
11. Phase Warp (Power 1000 2-channel amplifier) The phase warp is a variable
control used to adjust the phase of the output signal relative to the phase of the
input signal. The phase warp is most noticable when the system is playing a
sine wave (test tone). When used with the proper test equipment, this feature
can increase the relative SPL in a system.
