PC36 frequency range must be set according to the cut-off frequency chosen for HI-PASS filter it must be used with.
PC36 module is able to vary relative phase
between two ways of a multiamplified system. Its
purpose is to make the emission of a speakers
system, located in different places in car, more
homogeneous. Generally speaking, PC36
module allows you to put the HI-PASS filtered way with electronic crossover in phase with regards to the one which
is LO-PASS filtered in a bi-amplified system. It is possible to use two PC36 in a three way amplified system: one to
align tweeters with regards to midwoofers and one to align midwoofers with regards to subwoofer.
Used into VRx4 and VRx6, PC36 allows the front system phase alignment with regards to subwoofer. Applied into
VRx2 and VRx1, it permits to put all crosses of a multiamplified system in phase if it is used together with HI-PASS
sections of HL12, HL24, BH12 modules or with BAND-PASS sections of BH12.
Pre-select frequencies ranges through jumpers according
to cut-off frequencies of the HI-PASS filter it is used with.
PC36 is originally set on 40 ÷ 200 Hz.

WARNING
The use of PC36 into VRx1 and VRx2 depends
on the installation of HL12, BH12, HL24
multichannel extensions, since PC36 acts only
on HI-PASS section.

Measures were realised through a test-set consisting of Rohde & Schwarz UPD audio analyser, HP 6453A power supply
(200A continuous) and 14F capacitive booster made with audison cable Superfarad capacitors.
Please always choose a fuse of equal or slightly higher value (max 10%) than indicated.
Note:
The use of MAC2 cooling system is strongly recommended when the amplifier is employed at full power with 1 Ohm
stereo or 2 Ohm bridged loads.
