Rear Panel Introduction
1. Input connection
It is a balanced 3 core XLR female socket.
2. Status selectionswitch
Push the switch to the position wanted. It is MONO mode at theleft, STEREO in the
middle and BRIDGE at the right.
A ) STEREO mode
STEREO is the most commonly used mode. Each channel will keep independent
when it is at stereo mode. The volumecontrol in front panel will workfor relevant
channel.
B) MONO mode
It is only the signal fromCH 1 will be used under the MONO mode. The signals from
all the output ends are thesame and the volume control knobs will control the
volume from relevant channels.
C) BRIDGE mode
It is only the signal fromCH 1 will be used under this mode. The signals fromthe
output ends will be the sameand the phasewill be contrast. All the output of the
amplifier will be gathered to a output end. Since the amplifieris used as a mono
equipment under the BRIDGE mode,the volume will be controlled byknob CH 1.
The knob at CH 2 doesnot work at this mode.
Please note, any end of the output cordcan not be grounded under theBRIDGE
mode because two ends of thecord are output. It isallowed the minimum
impedance to be twice of the one under the normal stereo or mono mode.
3. Cool AirVent
It is the vent for coolair to flow into the amplifier. Pls do not block itwith any stuff or
place any thing in the frontof the vent when the amplifier is at workingstatus.
4. Alternating Inputsocket
o be connected with suitable alternatingelectric power via the power cord.

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 downOFF 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 itis at
default working modeSTEREO, these indicator lights will not shine.
4. Working status indicator STATUS
When the powerto the amplifier is turned on, the light STATUS will be lightenup.
When the amplifieris at normal working status, the LED light STATUS will be lightenup
in green color. When theamplifier is under protection and mute status, itwill flash in
RED color.
5. Signal indicators SIGNAL , CLIPand -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 CLIPlightens up, it shows the output level is higher
than the ratedvalue and the amplifier is atprotection status.
6. VolumeControl
The VolumeControl knob is used to adjust the volume. When it is turned at
clockwise direction, the volume willbe increased. Wen it is turned at
anti-clockwise direction, the volume willbe decrease.
As to the2 channel amplifier, when itis at STEREO mode or MONOmode, turn
the volume controlknobs at CH 1 and CH2 to reachthe wanted volume level.
But when itis at BRIDGE mode, turnonly the knobs at Ch1 toget the volume
wanted. The knob at CH 2 does notwork under BRIDGE mode.

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.
