The Punch 4020 is a 4-channel amplifier which offers 20 Watts
per channel when driven into 4 Ohms. The amplifier utilizes a 2/
4 input selector switch and XCard crossovers.
When building a 4-channel amplifier, a major design challenge
is to maintain sound quality in a limited space. For the Punch
4020, Rockford Fosgate Engineers designed the Trans•
Ana
to-
pology which is a fast, short loop circuit allowing the output stage
to be driven with a low voltage drive signal. With the addition of
a 2/4 input selector switch and XCard crossovers, the 4020 can
be configured in many popular system designs without the added
cost of external processors. The result is an excellent sounding
amplifier in a physically compact area.
The Punch 4020 satisfies the need for a powerful 4-channel
amplifier at a competitive price.
We strongly recommend you have your Authorized Rockford
Fosgate Dealer install the new Punch 4020 amplifier. If you do
choose to install it yourself, please be sure to read the entire
manual before beginning.
