Rockford Fosgate 1000 - Manual (Page 11)

– 6 –
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 conven-
tional extrusion heatsink designs.
2. Speaker/Power Terminals – The heavy duty, gold-plated terminal block
connectors (+ 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 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.
