4. Connections
4.1 Inputs:
The inputs CH 1 INPUT (1) and CH 2 INPUT (2)
are equipped with XLR/jack compound sockets,
wired for balanced operation (see fig.3). These
inputs must be wired to the outputs of the mixer
(e.g. STAC M 810 / EM 810). If needed, more units
like active crossovers ore equalizers can be added
to the setup by connecting them between mixer
and power amplifier.
The FORCE 180 offers both XLR and 1/4" inputs
for matching the outputs of other units (see fig.
2.1).
If the BRIDGE switch (14) of the FORCE 180 has
been activated to run the amplifier mono (see also
chapter 5.4), use only the CH 1 INPUT (1).
4.2 Outputs (Fig. 4):
The outputs CH 1 OUTPUT (3) and CH 2 OUTPUT
(4) are equipped with Speakon and binding-post
connectors. For stereo operation, either Speakon
or binding-post outputs can be used for connection
of speakers (see fig. 4.1 and 4.2), depending on
the connectors used on the speakers. When
connecting speakers, always watch for correct
polarity for the left and the right side to avoid
sound cancellations. If the amplifier has been
switched to monaural bridge mode (see chapter
5.4), only the BRIDGE output (5) can be used (see
fig. 4.3).
4.3 Mains supply:
Mains connection is provided by a euro-style
mains cable which must be connected to the AC
INPUT socket (16). The FORCE 180 is configured
for 230 VAC / 50Hz mains supply voltage.
For overcurrent protection, the FORCE 180 is
equipped with a reset-fuse that does not require
one-way fuses. If the automatic fuse is triggered by
overcurrent, resetting it brings the FORCE 180
back to operation.
