WARNING: PAY ATTENTIONTO A PROCEDURE,PRACTICE, CONDI-
TION OR THE LIKE,IFNOT CORRECTLY PERFORMEDOR ADHERED
TO, COULD RESULTIN PERSONAL INJURY OR DEATH.
CAUTION! Do not locate sensitive high-gain equipment such as
preamplifers or tape decks directly above or belo-w the unit. be
cause this amplifer has a high power density,it has a strong mag
netic feld which can induce hum into unshielded devices that are
located nearby. the feld is strongest just above and below the unit.
If an equipment rack is used,we recommend locating the
amplifer(s) in the bottom of the rack and the rack and the preamplifer
or other sensitive equipment at the top.

IMPORTANT
XLi series amplifers requireclass 2 output wiring.
The device is designedand evaluated under thecondi
tion of non-tropical climate;and,it canbe only used
in locations in non-tropicalclimate areas. Using the
device in tropical climateareas would result inhigh
safety risk.
This device is designed andevaluated under the con
dition of 2000 meterstall above sea lever;and,itcan
be only used inlocations below 2000 meterstall above

Bridge-Mono Wiring Using the Speakon Connectors
Bridge-mono mode doubles the output power of the amplifer.
1. See thefollowing figure. Onthe back panel,set the Output Mode switch toBRIDGE.
2. Wire the speaker to the speakon connector as shown.
3. Only theChannel 1 Gain Control works inBridge-mono mode.

Rear Panel Introduction
1. Input connection
It is abalanced 3 core XLR female socket.
2. Status selectionswitch
Push the switch to the position wanted. It is MONOmode at the left, STEREO in the
middle and BRIDGEat the right.
A ) STEREO mode
STEREO is themost commonly used mode. Each channel will keep independent
when it isat stereo mode. The volume control in frontpanel will work for relevant
channel.
B) MONO mode
It is onlythe signal from CH 1 will be used underthe MONO mode. The signals from
all the outputends are the same and the volume control knobswill control the
volume from relevantchannels.
C) BRIDGE mode
It is onlythe signal from CH 1 will be used underthis mode. The signals from the
output ends willbe the same and the phase will be contrast. All the output of the
amplifier will begathered to a output end. Since the amplifier is used asa mono
equipment under theBRIDGE mode, the volume will be controlled byknob CH 1.
The knob atCH 2 does not work at this mode.
Please note, any end ofthe output cord can not be grounded under the BRIDGE
mode because twoends of the cord are output. It is allowed the minimum
impedance to betwice of the one under the normal stereo or mono mode.
3. Cool AirVent
It is thevent for cool air to flow into the amplifier. Pls do not block itwith any stuff or
place any thingin the front of the vent when the amplifieris at working status.
4. Alternating Inputsocket
To be connected with suitablealternating electric power via the powercord.
Protection Functions
Digital power amplifier D series have full protection function against
short circuit, direction current, over-load, over-heat and lower voltage.
The protection will help to prevent possible damage to the equipment
under the extreme situation.
1. Protection against short circuit
The protection circuit of the amplifier will monitor the current output
situation at any time in operation. When short circuit happens or
when the amplifier connects to the load with lower impedance, this
protection function will start to work. The output of the amplifier will
close and the protection circuit will detect the situation every few
seconds automatically. When the short circuit or over-current
disappear, the amplifier will resume to normal work situation.
The protection to very channel will work independently. When the
amplifier is under STEREO mode or MONO mode, if short circuit
happens at any one of the channels, this channel will be in
protected situation, but the other channels will still work normally.
When the amplifier is under BRIDGE mode, every two channels
of the amplifier will be connected to be one channel. So only one
channel of two channel will be found output short circuit (including
grounded short circuit) or over-current. Two channel will be in short-
circuit protection status.
NOTE :
This amplifier is with full short-circuit protection. But long lasting
short-circuit should beavoided by effort because long time
short-circuit may causeover-heat to inside components of the
amplifier and affect the using life of the amplifier.
2. Protection against direction current and secondary audio
When the amplifier is detected to find direct voltage or large range
of secondary audio( lower than 20Hz) signals at the output end, the
amplifier will be in the protection status. It will prevent damage
to the speaker systems. At the same time, the STATUS indicator in
front of the panel will turn from green to orange.

Front Panel Introduction
1. Power On/Off Switch
PLS push downON to turn on the powerof the amplifier, push down OFF to turn off.
2. Air Vent
It is thevent for the heated air toflow through from inside of theamplifier. Pls do not
put any stuffinside or in the front ofthe vent to block the airflow.
LED Indicators
The user canknow the working status of every channelwith these LED indication lights.
The LED lightsincludes three kinds of indicator asthe following:
3. Working mode indicators MONO and BRIDGE
When the modeselection switch in the rear panelis turned to BRIDGE or MONO,
the relevant LEDlight in front panel will belighten up at the same time. When it is at
default working modeSTEREO, these indicator lights will not shine.
4. Signal indicators SIGNAL , CLIP and -10dB
Even very small outputcan make SIGNAL to lighten up, it shows relevant channel is
at work. When the light -10dB lightens up, it shows the output levelis -10dB under
the rated value. When CLIP lightens up, it shows theoutput level is higher
than the ratedvalue and the amplifier is at protection status.
5. VolumeControl
The VolumeControl knob is used to adjust the volume. When it isturned at
clockwise direction, the volume will be increased. Wen it is turned at
anti-clockwise direction, the volume will be decrease.
As to the2 channel amplifier, when itis at STEREO mode or MONOmode, turn
the volume controlknobs at CH 1 and CH 2 to reach the wanted volumelevel.
But when itis at BRIDGE mode, turn only the knobsat Ch1 to get the volume
wanted. The knob at CH 2 does not work under BRIDGEmode.
3. Starting delay and mute
There is a soft start procedure inside the amplifier after turn the
power switch to ON position. During this time, the amplifier will
be in protection status. The STATUS light will turn to orange color.
The amplifier will turn to normal work status after about 4 seconds
and the STATUS light will turn from orange to green. All the other
indicator lights will lighten up to show the live mode.
When turn the power switch to OFF position, the amplifier will be
in shut off status. The light STATUS will turn from green to orange
and turn off finally.
4. Protection against over-heat
When the temperature of the main cooling system of the
amplifier is under 50 centi-degree, the cooling fan will run at
very low speed. When it is between 50 and 70 centidegree,the
cooling fan will run from slow speed via stepless speed change
to full speed. When the temperature of the main cooling system
reaches 90 centi-degree, the STATUS light will start to flash green
and orange alternatively, which warns the user high temperature
of the cooling system and to lower down the output intensity. .
NOTE
When the protection status happens at starting of the
amplifier, it shows there maybe serious damage
inside the amplifier. Pls shut off the power and take
off the power cord . Then send the amplifier to the
professional expert for maintenance.
