When using low impedance connections with
Double Power mode
If you use Double Power mode, input/output will be dis-
abled for channels B, D, F and H.
Depending on the impedance (4Ω or 8Ω) of the connected
speakers, set the [SPEAKERS] DIP switches as follows.
When using high impedance connections
Depending on the specifications (70V or 100V) of the
system in which this unit is being installed, set the
[SPEAKERS] DIP switches as follows.
Connecting Speaker Cables
The [SPEAKERS] output connectors (page 15) on the rear
panel are barrier strip type connectors. We will explain con-
nections using a spade lug and connections using a bare con-
ductor.
If using a spade lug
From below, insert the spade lug all the way, and tighten
the screw.
If using a bare conductor
Wrap the conductor around the barrier strip terminal as
shown below, and tighten the screw. Be sure that the bare
wire does not touch the chassis.
Connecting the Power Cord
Connect the included power cord to the [AC IN] connector
(page 15) on the rear panel. First connect the AC power cord
to the connector on this unit, then plug it into an appropriate
AC power outlet.
