n XLR connector PIN arrangement
ew q
q GND (Ground)
w HOT (Hot)
e COLD (Cold)
The PIN arrangement in this device uses the European method.
In the USA method,
w
is COLD, and
e
is HOT.
When connecting a device that utilizes the USA type of PIN arrangement, replace
the
w
and
e
plugs on one side of the balanced cable.
NOTE
Do not short the HOT and GND or COLD and GND for use.
Speaker connections
Carefully check the channels of the speakers to be
connected to this unit (L/R/SL/SR/C) and + (red), –
(black), and connect like poles together.
Connecting the speaker cables
Peel off about 10 mm of sheathing from the tip
of the speaker cable, then either twist the core
wire tightly or terminate it.
NOTE
• Connect so that the speaker cable core wires
do not protrude from the speaker terminal.
The protection circuit may be activated if the
core wires touch the rear panel or if the + and –
sides touch each other (vpage10 “Protection
circuit”).
• Never touch the speaker terminals while the
power supply is connected. Doing so could
result in electric shock.
• Use speakers with impedance of 6 ohms or
more.
