Warnings
• Do not allow water to enter this unit or allow the unit to
become wet. Fire or electrical shock may result.
• Connect this unit’s power cord only to an AC outlet of the
type stated in this Owner’s Manual or as marked on the unit.
Failure to do so is a fire and electrical shock hazard.
• Do not scratch, bend, twist, pull, or heat the power cord. A
damaged power cord is a fire and electrical shock hazard.
• Do not place heavy objects, including this unit, on top of the
power cord. A damaged power cord is a fire and electrical
shock hazard. In particular, be careful not to place heavy
objects on a power cord covered by a carpet.
• If you notice any abnormality, such as smoke, odor, or
noise, or if a foreign object or liquid gets inside the unit,
turn it off immediately. Remove the power cord from the
AC outlet. Consult your dealer for repair. Using the unit in
this condition is a fire and electrical shock hazard.
• Should this unit/AC adapter/power supply be dropped or the
cabinet be damaged, turn the power switch off, remove the
power plug from the AC outlet, and contact your dealer. If
you continue using the unit without heeding this instruction,
fire or electrical shock may result.
• If the power cord is damaged (i.e., cut or a bare wire is
exposed), ask your dealer for a replacement. Using the unit
with a damaged power cord is a fire and electrical shock
hazard.
• Do not remove the unit’s cover. You could receive an
electrical shock. If you think internal inspection, mainte-
nance, or repair is necessary, contact your dealer.
• Do not modify the unit. Doing so is a fire and electrical
shock hazard.
Cautions
• When rack-mounting the unit, allow enough free space
around the unit for normal ventilation. This should be: 10
cm at the sides, 30 cm behind, and 20 cm above.
For normal ventilation during use, remove the rear of the
rack or open a ventilation hole.
If the airflow is not adequate, the unit will heat up inside and
may cause a fire.
• To mount several of these units in an EIA-compliant rack,
refer to the rack mounting instructions on page 8.
• This unit has ventilation holes at the (top, bottom, front,
rear, and sides) to prevent the internal temperature rising too
high. Do not block them. Blocked ventilation holes are a fire
hazard.
• Clean the contacts of the phone plug before connecting it to
the SPEAKERS jack of this unit. Dirty contacts may
generate heat.
• Use only speaker cables when connecting speakers to
amplifier outputs. Using other types of cables is a fire
hazard.
• Hold the power cord plug when disconnecting it from an AC
outlet. Never pull the cord. A damaged power cord is a
potential fire and electrical shock hazard.
• Do not touch the power plug with wet hands. Doing so is a
potential electrical shock hazard.
• Do not use this amplifier for any purpose other than driving
loudspeakers.
Usage
• Using a mobile telephone near this unit may induce noise. If
noise occurs, use the telephone away from the unit.
• XLR-type connectors are wired as follows: pin 1: ground,
pin 2: hot (+), and pin 3: cold (–).

Controls and Functions
■ Front Panel
1 POWER switch and indicator
This is the main POWER switch. Press to turn on the
amplifier. Press it again to turn off. The POWER
indicator lights up when the amplifier it turned on.
2 PROTECTION indicator
When the protection system is active, the PROTEC-
TION indicator lights up and the speakers are auto-
matically disconnected from the amplifier’s outputs.
The protection 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
automatically and the amplifier is ready for normal
operation.
• If a DC voltage is detected at the amplifier’s
outputs
The protection system activates if a DC voltage is
detected at the amplifier’s outputs. Once the DC
voltage problem is corrected, the protection system
deactivates automatically and the amplifier is ready
for normal operation.
• If the amplifier overheats
If the amplifier overheats, the protection system
activates. In this case, you should turn off the ampli-
fier and allow it time to cool down. When it has
cooled down, the protection system deactivates
automatically and the amplifier can be turned on again
ready for normal operation. See the Precautions
section of this Owner’s Manual for ways to prevent
the amplifier overheating.
3 CLIP 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.
4 SIGNAL indicator
A channel’s SIGNAL indicator lights up when its
output exceeds 2 V rms, which is equivalent to 1/2
watt into 8 ohms, or 1 watt into 4 ohms.

■ Rear Panel
1 HPF switches
These switches are used to turn on and off the HPF
(High Pass Filter) for each channel. When set to ON,
frequencies below 80 Hz are filtered using a 12 dB/
octave high pass filter.
Turn this switch ON if 70V-line, high-impedance
speakers are connected.
In Bridge mode, only the HPF switch of the first
channel in the pair is active, i.e., channel A of pair A–
B, channel C of pair C–D, and channel E of pair E–F
(XM6150 only).
2 Attenuators
These detented controls are used to attenuate the input
signal from –∞ dB to 0 dB for each channel.
In Bridge mode, only the attenuator of the first channel
in the pair is active, i.e., channel A of pair A–B,
channel C of pair C–D, and channel E of pair E–F
(XM6150 only).
3 XLR inputs
These balanced XLR-3-31 type connectors are used to
connect input signals. They are wired pin 1–ground,
pin 2–hot (+), and pin 3–cold (–).

4 Euroblock connectors
These balanced Euroblock connectors are used to
connect input signals.
In Bridge mode, only the Euroblock connector of the
first channel in the pair is active, i.e., channel A of pair
A–B, channel C of pair C–D, and channel E of pair E–
F (XM6150 only).
5 CH A TO ALL CH switch
This switch is used to feed the input signal connected
to channel A to all channels.
When set to EACH CH, the input signal connected to
each channel is amplified and output by each channel
respectively. When set to CH A TO ALL CH,
however, the input signal connected to channel A is
fed to all channels.
6 BRIDGE switches
These switches are used to bridge the following
channel pairs: A–B, C–D, and E–F (XM6150 only).
When set to OFF, the two channels operate indepen-
dently. For example, the signal connected to input
channel A is amplified and output by the channel A
outputs, while the signal connected to input channel B
is amplified and output by the channel B outputs.
When set to BRIDGE, the signal connected to input
channel A is amplified and output by the bridged
outputs A–B, and channel B’s inputs are not used.
* The illustration shows model XM6150.

In Bridge mode, you can connect multiple high-
impedance speakers (that are compatible with 70V
line output) in parallel. The number of speakers you
can connect is determined by the rated input of each
speaker. For each channel, you can connect speakers
as long as the speakers’ total rated input does not
exceed 150W (for XM6150) or 350W (for XM4220).

Rack Mounting
If multiple high-power amp units are mounted in a rack with poor ventilation, the heat from the amps will cause the
interior of the amp to become very hot, causing the performance of the amps to be impaired. In particular, when
mounting in a rack whose back can not be left open, mount according to the following instructions.
Rack: Leave a gap of 10 cm or more between the rear panel of the rack and the rear panel of the amplifier.
Fan: Use a fan with 1.5 m
3
/min or more maximum wind and 5 mmH
2
O or more maximum static pressure.
Mounting: Install the fan kit on the top slot or the top panel of the rack and install a blanking panel between two
amps.
Ventilation panel:. The ventilation panel should be a 1U size, and more than 35% of the entire area should be
open.
Example of mounting
The figure on the left below shows an example of a fan kit (panels and two fans) on the top slot of the rack. The fans
are Minebia 3115PS-12T-B30 (with 0.9 m
