Important operation or special note
Risk of electrical shock
The DP-i Series is suitable for fixed installation applications.
Compact, lightweight and stable structure in a rugged 1U, 19 " rack mount enclosure.
The built in PFC (Power Factor Correction) allows worldwide operation with any AC mains voltage, from 90 to 260 V.
DP-i Series is designed to work with Lo-Z mode (2 -16 Ω) and Hi-Z mode (100 V / 70 V distributed lines).
A full suite of protection includes thermal , over-current, DC, short circuit protect and power on/ off mute.
The variable speed fans keep the amplifier rack quiet when standby.
The DP-i series features 3 different operating modes. Mono, Stereo and Bridge.

The cooling mode of the equipment is as follows:
Cold air is sucked through the ventilation holes of the front panel
and the heat is expelled from the rear panel. In order to ensure
good heat dissipation, please keep the equipment in the 0 ~40
degrees range and ensure that the front and rear panel airways are
clear.
If the temperature exceeds 85 degrees, output voltage will be
reduced. If the temperature continues rise to 90 degrees, the power
amplifier will be shut down. When the temperature drops back to a
safe temperature, the equipment will restart automatically.
After long term use, if the cooling effect becomes reduced, please
turn off the equipment and remove the front dust net cover
to clean out any dust that may have built up.

QUICK START GUIDE
Speaker protection
Clipping not only distorts the sound, but it also damages the transducers (drivers) of your loudspeakers.
If clipping occurs, reduce the input signal level to avoid clipping.
Strong sub signals can also burn low frequency drivers. The high level low frequency signal caused by (eg) dropping a
microphone is a typical sub acoustic signal. Always use methods to prevent sub sonic signals a、Install a high pass filter
between the mixer and the amplifier.
b、Turn on the high pass filter in the mixer. Without affecting the use, the filter frequency is set as high as possible. For
example, for the music signal is set to 35 Hz, for a microphone set it to 75 Hz.
Attention
In order to achieve the best performance and the highest security, please pay attention:
1、 Before use, you need to configure the amplifier, including the input and output cables. Improper wiring will lead
to the equipment not working correctly and can cause damage. For information about connections please refer to the
“installation” section of this manual.
2、 Be careful when connecting, selecting the input signal and controlling the output level.
3、 Do not connect the ground wire of the input and output cable together. This will form a ground loop and will
cause oscillations.
4、 Never connect the output cable to a power supply, It will cause electric shock.
5、 Never make any modifications to the circuitry. It will void any warranty or support.
6、 Do not use the amplifier if the SIG LED continuously flashes yellow.
7、 Do not overload the mixer outputs. Overloading will send clipped signals to the amplifie inputs. The amplifier
will accurately reproduce such signals, and the connected loudspeakers can easily be damaged.
8、 Do not use the amplifier under the condition of lower than the nominal load. Too low load may cause amplifier
output protection and premature clipping.
9、 When the amplifier is turned on, the output connections are active. Never touch as the power output can be
fatal.
