■ Complete Bi-Amp Connection
Enhance the connection 2, by having one more control Amp.
SC-7S1, this is a wiring which
separates Mid / High (MF/HF) signal and Low (LF) signal from
Pre-Amp section.
In this event, SC-7S1 is used as Monaural Amps. And sepa-
rate Left/Right channels from output terminal of CD players.
As a result, influences between L channel and R channel Mid
/ High signal and Low signal will be eliminated.
By connection with remote cabel, maiximamly 6 pcs can be
interlock operated.
Caution
In the event of setting mode switch as , B chan-
nel input terminals can’t be used.
■ Balanced terminal
q The balanced output connector uses a XLR connector.
w The XLR connector for professional use is internally
wired in either of the following two systems.
1. USA system (Pin 2 = COLD, Pin 3 = HOT)
2. European system (Pin 2 = HOT, Pin 3 = COLD)
e The MA-9S1 uses the USA system of 1.
When a preamp or main amplifier adopting the European
system is connected using a cable with XLR balanced
connectors, the reproduced signal may be inverted of
phase.
In this case, correct the wiring of the one of the XLR con-
nectors on the extremities of the cable to the USA system
by exchanging the connections of pins 2 and 3. This will
make it possible to play the signal with the correct phase.
