The Punch 3X and the Punch 5X both have Dual Filter sections. The
Dual Filter is a two stage cascaded filter which uses two cards. The first
card determines the initial action and the second, the subsequent
action. The most common usage would be to use a low-pass module
in the first position followed by a high-pass module in the second to
build a bandpass function. By using two cards of the same action at
the same frequency the filter slope is increased to 24dB per octave.
Both sockets must be used for a simple 12dB per octave filter. Install
the card in the second position for full range operation.
The operation of each filter section is determined by the use of plug
in cards. These multifunctional cards are available for a multitude of
operational frequencies, and their orientation in the socket deter-
mines their function. Each socket has a blank plastic side which
positions the card against the spring loaded contacts. The front, or
active, face of the card is marked with arrows to indicate which edge
plugs into the socket. Orient the card with the chosen face toward the
contacts and plug it into the socket of the appropriate filter operation.
The rear face of the card is for full range operation and either edge can
be used.
