Rockford Fosgate 250, 360, 400, 500, 600, 800, 1000 manual Design Features

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 5–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.
