Rockford Fosgate Punch 100.2 Installation & Operation Manual page 11

1. Cast Aluminum Heatsink – The cast aluminum heatsink of the Punch
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 – These gold-plated connectors are used for
the connection of speaker and power wire and are immune to corro-
sion that can cause signal degradation. The Punch 120 and Punch
160 utilize a barrier strip that will accept #10 spade lugs or bare
speaker and power wires sized from 10-18 AWG. The Punch 250,
Punch 360, Punch 500, and Punch 800 utilize heavy duty terminal
block connectors that will accept bare wires size from 8-18AWG.
3. REM Terminal – This spade terminal is used to remotely turn-on and
turn-off the amplifier when +12V DC is applied.
4. RCA Input Jacks – The industry standard RCA jack provides an easy
connection for signal level input. They are gold-plated to resist the
signal degradation caused by corrosion.
5. High Level Inputs – The high level inputs use a detachable connector
terminated with 20 AWG leads. These inputs should be used if the
source unit has only speaker line (high level) outputs and not RCA
outputs.
6. Gain Control – The input gain control is preset to match the output
of most source units. They can be adjusted to match output levels
from a variety of source units. For assistance setting the gain correctly,
contact Technical Support at 1-800-669-9899.
7. Punch Bass – The Punch Bass helps correct for acoustical deficiencies
in the listening environment. The Punch Bass allows a narrow band
adjustment at 45Hz to help reproduce full range sound without exces-
sive boost. The Punch 120 utilizes a switch that is adjustable at
0dB/+6dB/+12dB increments. The Punch 160, Punch 250, Punch
360, Punch 500, and Punch 800 utilize a Remote Bass control that is
variable from 0dB to +18dB.
8. Internal Crossover – The internal crossover is used to delegate a spe-
cific range of frequencies to the speaker system for optimum perform-
ance. The crossover can perform three functions: High-Pass (HP),
Low-Pass (LP), or Full Range (FULL). The Punch 120 and Punch 160
utilize a 12dB/octave Butterworth crossover fixed at 120Hz HP and
80Hz LP. The Punch 250, Punch 360, Punch 500, and Punch 800 uti-
lize a 12dB/octave Butterworth crossover variable from 50Hz to
210Hz.
9. LED Power Indicator – The LED illuminates when the unit is turned on.
