XLR inputs connectors

These balanced XLR-3-31 type connectors are used to

connect input signals.

The pins are wired as shown below (IEC 60268).

Hot

* In bridged mode, only the ﬁrst channel in the pair is

active; i.e., channel A of pair A/B, and channel C of

pair C/D. Make sure not to input an audio signal to

an inactive input terminal.

Euroblock connectors

These balanced Euroblock connectors are used to con-

nect input signals.

HPF switches

These switches are used to turn on and off the HPF

(High Pass Filter) for channels A-B or C-D. When this

is set to 20Hz or 55Hz, frequencies below the respective

settings are ﬁltered using a 12 dB/octave high pass ﬁlter.

MODE switch

STEREO mode

In STEREO mode, channels A , B, C and D are com-

pletely independent.

PARALLEL mode

In PARALLEL mode, the channel A input signal is

sent both to the channel A power amp and the channel

B power amp. In this case, loads are automatically

connected between the A and B input terminals. (The

same applies to the C and D input terminals.)

By sending the signal from channels A/B to C/D you

can use the unit as a four-channel mono ampliﬁer.

Ground

Cold

* The illustration shows model XM4180.

BRIDGED mode

In BRIDGED mode, channels A and B operate simul-

taneously, functioning as a single mono ampliﬁer.

(The same applies to the C and D.)

Note: When in PARALLEL and BRIDGED modes,

input terminals A-B and C-D are shorted

automatically. Make sure not to input an

audio signal to an inactive input terminal.

MONITOR/REMOTE terminals

This terminal is used to connect the external device for

monitoring or remote control. Refer to "MONITOR/

REMOTE PIN layout" on page 14.

SPEAKERS terminals

These 5-way binding posts are used to connect speak-

ers.

GND terminal

If you are having a problem with hum or noise, use this

terminal to connect to ground (earth) or to connect to

the chassis of a mixer, preamp, or other device in your

system.

AC IN

Connect one plug of the included AC cable to this inlet.

Connect the other plug of the AC cable to an AC outlet

that meets the power supply conditions printed on the

label at the top of the unit.
