A Gyrator based Punch EQ that eliminates frequency
shift with boost. This works along with the crossover
switch on the ampliﬁer.
The power and ground will accommodate 4 AWG,
while the remote will accommodate 12 AWG.(The
REM terminal is used to remotely turn-on and
turn-off the ampliﬁer when +12V DC is applied.)
2/4 Channel Switch
Setting this switch to the 2CH. position, switches the
inputs to a 2-channel mode, allowing connection to
only the front inputs with a 4-channel output. (P400X4,
Selectable switch for High-Pass (HP) or
All Pass (AP) or Low-Pass (LP)
Is a built-in 12dB/octave Butterworth ﬁlter with
a crossover point variable from 50Hz to 250Hz.
Remote Punch Level Control - In/Out
Remotely control the output level of the ampliﬁer. The
PLC-OUT is used to daisy-chain additional ampliﬁers
controlled by a single remote.
A ﬁxed 28Hz 12dB/octave ﬁlter designed to prevent
frequencies below the audio range from being applied
to the subwoofer from the ampliﬁer. Consequently
improving subwoofer performance and power han-
dling, particularly in vented enclosures. (P500X1BD,
Remote Punch Level Switch
When activated, this allows the use of a optional re-
mote Punch Level Controller. (P500X1BD, P10001BD,
2CH. - 4CH.
