COMPLETE BI-AMP CONNECTION
Enhance connection 2, by having one more control Amp. SC-
7S2, this is a Complete Bi-Amp connection which separates
Mid / High (MF/HF) signal and Low (LF) signal from Pre-Amp
section.
In this event, SC-7S2 is using as Monaural Amps. And separate
Left/Right channels from the output terminal of CD players.
As a result, influences between L channel and R channel Mid
/ High signal and Low signal will be eliminated.
A maximum of 6 SC-7S2s, can be connected to each other,
via remote cables.
Caution:
In the event of setting mode switch as <Bi-Amp>, B channel
input terminals can’t be used.
BALANCED TERMINAL
q The balanced output connector uses a XLR connector.
w The XLR connector 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-9S2 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
connectors 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.
