Controls and Functions

■

Front Panel

POWER/STANDBY switch and indicator

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.

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.

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.

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.)

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).

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.
