TION OR THE LIKE,IF NOT CORRECTLY PERFORMED OR ADHERED
TO, COULD RESULT IN PERSONAL INJURY OR DEATH.
CAUTION! Do not locate sensitive high-gain equipment such as
preamplifiers or tape decks directly above or belo-w the unit. be
cause this amplifier has a high power density, it has a strong mag
netic field which can induce hum into unshielded devices that are
located nearby. the field is strongest just above and below the unit.
If an equipment rack is used, we recommend locating the
amplifier(s) in the bottom of the rack and the rack and the preamplifier
or other sensitive equipment at the top.
MAGNETIC FIELD
IMPORTANT
XLi series amplifers require class 2 output wiring.
The device is designed and evaluated under the condi
tion of non-tropical climate;and,it can be only used
in locations in non-tropical climate areas. Using the
device in tropical climate areas would result in high
safety risk.
This device is designed and evaluated under the con
dition of 2000 meters tall above sea lever;and,it can
be only used in locations below 2000 meters tall above
sea level. Using the device above 2000 meters altitude
would result in high safety risk.
The exclamation point triangle is used to alert the
user to important operating or maintenance instruc
tions.
The lightning bolt triangle is used to alert the user to
the risk of electric shock.
WATCH FOR THESE SYMBOLS:
CAUTION: PAY ATTENTION TO PROCEDURE,PRACTICE,
CONDITION OR THE LIKE,IF NOT CORRECTLY PERFORMED OR

D series Power Amplifiers

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 ever y 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 be avoided by effort because long time
short-circuit may cause over-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 secondar y 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.

D series Power Amplifiers
Product Features
www.newhank.com

Front Panel Introduction
1. Power On/Off Switch
PLS push down ON to turn on the power of the amplifier, push down OFF to turn off.
2. Air Vent
It is the vent for the heated air to flow through from inside of the amplifier. Pls do not
put any stuff inside or in the front of the vent to block the air flow.
LED Indicators
The user can know the working status of every channel with these LED indication lights.
The LED lights includes three kinds of indicator as the following:
3. Working mode indicators MONO and BRIDGE
When the mode selection switch in the rear panel is turned to BRIDGE or MONO,
the relevant LED light in front panel will be lighten up at the same time. When it is at
default working mode STEREO, these indicator lights will not shine.
4. Signal indicators SIGNAL , CLIP and -10dB
Even ver y small output can make SIGNAL to lighten up, it shows relevant channel is
at work. When the light -10dB lightens up, it shows the output level is -10dB under
the rated value. When CLIP lightens up, it shows the output level is higher
than the rated value and the amplifier is at protection status.
5. Volume Control
The Volume Control knob is used to adjust the volume. When it is turned at
clockwise direction, the volume will be increased. Wen it is turned at
anti-clockwise direction, the volume will be decrease.
As to the 2 channel amplifier, when it is at STEREO mode or MONO mode, turn
the volume control knobs at CH 1 and CH 2 to reach the wanted volume level.
But when it is at BRIDGE mode, turn only the knobs at Ch1 to get the volume
wanted. The knob at CH 2 does not work 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.

Rear Panel Introduction
1. Input connection
It is a balanced 3 core XLR female socket.
2. Status selection switch
Push the switch to the position wanted. It is MONO mode at the left, 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 volume control in front panel will work for relevant
channel.
B) MONO mode
It is only the signal from CH 1 will be used under the MONO mode. The signals from
all the output ends are the same and the volume control knobs will control the
volume from relevant channels.
C) BRIDGE mode
It is only the signal from CH 1 will be used under this mode. The signals from the
output ends will be the same and the phase will be contrast. All the output of the
amplifier will be gathered to a output end. Since the amplifier is used as a mono
equipment under the BRIDGE mode, the volume will be controlled by knob CH 1.
The knob at CH 2 does not work at this mode.
Please note, any end of the output cord can not be grounded under the BRIDGE
mode because two ends of the cord are output. It is allowed the minimum
impedance to be twice of the one under the normal stereo or mono mode.
3. Cool Air Vent
It is the vent for cool air to flow into the amplifier. Pls do not block it with any stuff or
place any thing in the front of the vent when the amplifier is at working status.
4. Alternating Input socket
To be connected with suitable alternating electric power via the power cord.
