The Punch 2-channel amplifiers offer unmatched quality and reliabil-
ity in high performancesound systems. The Punch amplifiers are built
using integrated Discrete Surface Mount
(DSM) technology. All
components are mounted directly on the main circuit board. This
shortens the signal path resulting in improved sound quality and
reliability. Features include:
Input level Controls -The adjustable input level controls are preset
atthefactoryto match with most popular source units. However, they
may be adjusted to allow precise matching with a wide range of
sources.
Punch Equalization Controls
-
The Punch bass and treble are finely
calibrated equalizer controls which are designed to correct for
frequency response problems found in most automobile interiors.
These controls make it possible to fine tune and adjust for the listening
environment when you are not using an external equalizer. When
used in combination with an equalizer the Punch controls should be
set to the flat position, fully counterclockwise.
Cast Aluminum
Heatsink
-
The oversized heatsink used on all the
Punch amplifiers is of cast aluminum construction. This provides
better heat dissipation to protect the circuit from thermal damage and
improve long term reliability.
End Caps- The bolt-on end caps add a visually symmetrical finish to
the amplifier. After the installation is complete, use the end caps to
cover the wires and give your system a clean, uncluttered look.
