INTRODUCTION

Rockford engineers designed the Punch 2-channel amplifiers to withstand
the rugged automotive environment while delivering superior sound quali­ty in a flexible, reliable, and efficient package. TRANS•ANA is a low volt­age circuit in the preamp stage of all Punch amplifiers that lets the music
sound crystal clear and very real, even when played at high volume levels.
This is matched with TOPAZ, a unique grounding circuit used to eliminate
noise problems associated with car audio systems and their installation.
Flexibility is accomplished with the use of a built-in crossover. The use of a
protection circuit called NOMAD, along with MOSFET and DSM (Discrete
Surface Mount) technologies improve amplifier efficiency. The result of
these components give the Punch amplifier awesome sound quality in a
“Bullet Proof” package. An explanation of these technologies, most of
which are exclusively designed and patented by Rockford, are described in
the Technical Design Features.

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 corro­sion 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 exces­sive 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 perform­ance. 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 uti­lize a 12dB/octave Butterworth crossover variable from 50Hz to
210Hz.

9. LED Power Indicator – The LED illuminates when the unit is turned on.
