Summary of products
DA digital amplifier is full-digital, with international standard 1.5U height and 19” width, novel
multi-channel design (sensitivity select function, compressor select function;stereo, parallel mode
and bridge mode select function etc) and status indicator of multi-channel can show the working
condition in each channel. We can supply different power supply for different areacountry. Generally
speaking, DA digital amplifier is the trend in pro-audio field for its remarkable advantages like small-
size, light-weight, high efficiency (above 95%) and save energy.
Performance and character
— DA digital amplifier is full-digital, and its height is 1.5U, width is 19 inch of international standard.
— The models of DA digital amplifier are provided from 2-channel to 6-channel for selection,and
20W/4Ω,300W/4Ω,400W/4Ω are optional at 2-channel.Various models can suit for many kinds
of occasions.
— Small size, light weight, low temperature, reliability, and output efficiency is up to 95%. Every
2-channel for a power unit and independent power supply which you can choose arbitrarily to
operate, The design of Power on/off switch, and pen choices of 110V±10%，220V±10%
power supply. for energy-saving and more convenient manipulation.
— Its design of multi-channel allows you to make audio reinforcement matrix easily, making point
sound source to facet sound source, which is perhaps you have never done before, provides
the reliability of live sound reinforcement for you.
— DA digital amplifier provides high-efficiency digital amplifying function for you, audio transf
-erred efficiency is up to 95%, and total efficiency is up to 80%. User can use it in any occasion
because of the characters of electromagnetism compatibility and high-energy saving.
— DA digital amplifier Suitable for the requirements of sound reinforcement for many applications
like commercial, company, entertainment, school and army etc.

Installation and manipulation
Installation Venue
Please install the amp in places that are with good air circulation. The amp can not be exposed
to direct sunshine, or near to heat source or radiator. Too much heat shall affect rack and interior
components. Damp and dusty environment shall also bring about malfunction of the amp.
Installation Notice
Long time operation near heat shall affect the amp performance. Please do not install the amp
near to heat source. Please keep the amp far away from frequency modulator and television as
much as possible, for example, if distance between amp and modulator and television is not enough,
noise and instability of television picture may be caused.
WARNING: To reduce the
risk of electric shock, do not
espose this apparatus to rain
or moisture.
CAUTION
RISK OF ELE CTRIC SHOCK
DO NOT OPEN
