Punch 4-Channel amplifiers are rated for safe operation
into loads of 2Q, or greater in stereo mode or 4Q in
bridged/mono configurations. The primary loads on any
amplifier come from directly connected speakers without
using capacitors. The measured resistance for each side
should not be less than 2Q stereo or 4R bridged/mono,
The Punch 4-Channel amplifiers are capable of bridged/
mono configurations.
This configuration enables you to:
Run amplifier as a separate 2 channel subwoofer or
l
satellite amplifier.
Create a high power stereo system
l
Run 2 channels with a bridged mono woofer and the
l
other 2 as a high-frequency stereo amp, etc.
Note: Both Punch 4-Channel amplifiers allow the
above 3 configurations all in one.
For more information refer to the wiring diagrams begin-
ning on page 18.
Note: To bridge the amplifier use the L+ and R-
speaker connectors.
Caution! Punch 4-Channel
mended for impedance loads below 2Q stereo or 4R
bridged/mono.
Be sure to observe proper speaker terminal polarity
throughout the system. It is critical for the Punch 4-
Channel to use the correct negative terminals for
right and left channels, since the RIGHT NEGATIVE
(-) terminal is the "hot" terminal for the right speaker.
DO NOT chassis ground any of the speaker leads as
unstable operation may result.
A passive crossover is a circuit that employs capacitors
and/or coils and is placed on speaker leads between the
amplifier and speaker to delegate frequencies in the
speaker's optimum performance range.
