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)
COLD GND
2 1
3
HOT
2. European system (Pin 2 = HOT, Pin 3 = COLD)
GND
2 1
HOT
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.
