2. INTRODUCTION
Welcome
Welcome to use Steel series professional audio
power amplifier. For your safet, please read the
caution before installing and operating the power
amplifier.
Steel series professional power amplifier has a
stable circuit and reasonable cooling layout and
the carefully selected components, concise manu-
facturing process, ling time burning test, to ensure
that the amplifier has excellent performance and
reliability.

Product Checking

Open de box to check your new amplifier. If you
find there is damage, please advise the logistic
company timely, and you have the right to claim for
ligistic company for the losscaused during trans-
port as you are the consignee.
Features
1. Adopt the E.I.A. international standard (2U)
3.5¨ (88mm) professional amplifier chassis.
2. Power supply design:
Each unit contains a set of ligical power supply.
Adjust the power output level voltage through
the logic power supply real-time dynamic control
circuit. And can real-time dynamically adapt to the
signal and load requirements, which can achieve
the optimal power matching under the wide load
conditions, and ensure the amplifier will not over-
heat.
3. Signal voltage limit:
There is a voltage limiter in each input channel,
by detecting the output signal and controlling the
input signal, to make the amplifier output will not in
the clipping state for a long time, protect the horn

will not be burned; and will automatically control
the input signals when the amplifier ir overheat-
ed, to make the amplifier reduce heating, and use
more safe.
4. Professional Speakon socket suit for the
engineering and touring performance.
5. To withstand the longo-term bumps along
the way, all the spare parts are through the
special reinforcement.
6. Adopt the precision CNC lashed to stamp
the integrated steel plate to make the struc-
ture extremely strong and be able to with-
stand the maximum transient pressure with-
out deformation.
7. Perfect protection function:
Amplifier provides many different types of pro-
tection functions, including DC protection, inter-
nal fault protection, input overload protection, RF
interference filter, output short circuit protection,
un-match load and high-frequency overload
protection, overheat protection of heat-sink and
tranformer and power supply input over-current
protection (over-current protection switch).
8. XLR balanced input and output.
Functions & Features
1. Efficient heat-sink, variable speed cooling fan,
ensures the amplifier working at the low temper-
ature.
2. Large annulator transformer, ensure the
enough power supply.
3. Exquisite shape and standard installation hole.
4. Perfect protection, including limit, the on/off
shock protection, DC protection, output shot
circuit protection, overheat protection.
5. In-built limiter, it is a very effective protection
against electrical damage to the speaker.
6. Excellent audio signal performance, which has
