4ch Amplifier equipped with a Sound Field Composer. I am equipped
with a Sound Field Composer circuit where you can enjoy the atmosphere
of 4ch in 2ch source. By a device to reproduce the pseudo 4ch, is output
from the speakers of another reverberation only component that is
included in the 2ch source, this circuit is aimed to reproduce the sense
of reality.
It uses a 2ch-4ch complementary circuit by BTL Type of actuation in
the MCA-V7, to drive each speaker in the SEPP circuit four sets 4ch
playback, I get a high-powered by BTL connection 2ch time. I have
adopted a quasi-complementary ITL · OTL circuit to circuit
configuration. In addition, with the aim of noise reduction by adopting
a low-noise silicon transistor. Equalizer circuit has become a
two-stage, and is stopping the transistor noise by using a PNP
transistor in the first stage. 4ch and two inputs, it is equipped with
the 4ch recording and playback terminal.
It is equipped with an pre-out main-in terminal of 4ch, it can be
used independently of the main amplifier and preamplifier.
