This is the main POWER switch. Press to turn on the
amplifier. Press it again to turn off. The POWER indica-
tor lights up when the amplifier it turned on.
STANDBY operation can only be set from an external
device, connected to the REMOTE terminal. When
STANDBY is on, the indicator is lit in orange.
2
PROTECT/MUTE indicator
When the protection system is active, the PROTECT
indicator lights up and the speakers are automatically
disconnected from the amplifier’s outputs. The protec-
tion system activates in the following situations:
When the amplifier is turned on
The protection system activates for approximately
three seconds when the amplifier is turned on. After
three seconds, the protection system deactivates auto-
matically and the amplifier is ready for normal opera-
tion.
If a DC voltage is detected at the amplifier’s out-
puts
The protection system activates if a DC voltage is
detected at the amplifier’s outputs. Once the DC volt-
age problem is corrected, the protection system deac-
tivates automatically and the amplifier is ready for
normal operation.
If the amplifier overheats
When overheating occurs, the PROTECT/MUTE
indicator lights. You should immediately turn off the
amplifier and allow it time to cool down. See the Pre-
cautions section of this Owner’s Manual for ways to
prevent the amplifier from overheating.
3
CLIP/LIMIT indicator
A channel’s CLIP indicator lights up when its output
distortion exceeds 1% (i.e., clipping). Output signal
clipping is typically caused by excessive input signal
levels. When this happens, the limiter is engaged auto-
matically.
4
SIGNAL indicator
A channel’s SIGNAL indicator lights up when its output
exceeds a certain amount (2V rms on the XM4180/
XM4080, 4V rms on the XH200.)
5
VOLUME controls
The channel volume controls have click detents for the
settings, and each channel can be set over a range of -
∞
dB to 0 dB. On the XM4180 and XM4080, when the
amplifier is set to bridged mode, only the first volume
control on each channel pair is used (i.e., for the A/B
pair, channel A is active, and for the C/D pair, channel C
is active).
6
Air intakes
The amplifier has a forced-air cooling fan that takes in
air from the front and exhausts it from the rear. Make
absolutely sure that these intakes are not obstructed.
Security cover
If you want to keep the volume settings from being
modified, attach the included security cover using
the screw holes shown below, so that the volume
controls are inaccessible.

● Cable preparation
•To prepare the cable for attachment to a Euroblock con-
nector, strip the wire as shown in the illustration, and use
stranded wire to make connections. With a Euroblock
connection, the stranded wire may be prone to breakage
because of metal fatigue due to the weight of the cable or
due to vibration. When rack-mounting your equipment,
use a lacing bar when possible to bundle and fasten the
cables.
• If cables will be frequently connected and disconnected,
as in the case of a portable installation, we recommend
that you use ferrules with insulation sleeves. Use a ferrule
whose conductor portion has an external diameter of 1.6
mm or less, and a length of approximately 7 mm (such as
the AI0, 5-6WH made by the Phoenix Contact corpora-
tion).
If you use stranded wire, do not tin (plate
with solder) the exposed end.
