FRONT PANEL DESCRIPTION
General
Thank you for purchasing a DAS power amplifier. It has been built with the most advanced modular
technology, and has been designed through the use of computer-aided design for both the electronic and
mechanical parts.
6
Level controls (C)
Use to set the output level of each channel. The maximum gain is achieved when the
LEVEL rotary potentiometer is turned fully clockwise.
Clip LED (D)
When the output signal distortion of the corresponding channel exceeds 1%, the LED will
light, due to the signal level being is too high.
Protection LED (E)
When circuit protection works, the LED will light, especially when the heat-sinks overheat
or detect the DC voltage in the amplifier. Also, turn on the amplifier and within three seconds,
the amplifier is ready to work, the LED will shine. When startup is complete or the problem is
removed, the LED will extinguish, and resume working normally.
Features
!Efficient linear power supply.
!Dual balanced XLR inputs.
!Speakon output connections.
!Variable speed front to back fan cooling.
!Front located volume controls.
!Input sensitivity switchable between 0.775V and 1.4V.
!Circuit breaker protection.
!Stereo, parallel and bridge operation modes.
!Protection against output short-circuits, overloading and overheating.
!Power, Clip, protection and signal LED indicators.
Signal LED (F)
When there is an input signal, the LED will light. If not, please check the gain
settings. If necessary, the gain can be increased. Check the input connection and signal
audio source. If the Clip LED shines a little or shows no signal, check the output wire
whether it is in short-circuit or not.
Cooling air grilles (G)
Fan cooling permits airflow through the most vital parts of the amplifier. Since the airflow
finds its way out through these grilles, keep them as clean and dust-free as possible to assure
proper cooling.

Mode switch (C)
STEREO mode makes the two channels work independently, CH1 input signal by CH1
output, CH 2 input by CH2 output.
BRIDGE mode makes CH1 input signals from the BRIDGE output socket, output
must use CH1 volume control to adjust the volume.
PARALLEL mode makes CH1 input signal by CH1 and CH2 output socket output.
The input socket of Ch2 has no effect. Channel's volume can be adjusted independently.
Speaker outputs (A)
Connecting speakers to each output it is done through Speakon-type connectors whose
pin assignments are:
Channel 1 (stereo and parallel modes) : pin +1 = positive / pin -1 = negative
Channel 2 (stereo and parallel modes) : pin +1 = positive / pin -1 = negative
Channel 1 (bridge mode) : pin +1 = positive / pin +2 = negative
Inputs (B)
CH1 and CH2 are directly connected to the mixer, the input and output connectors
of the respective channel are put together, to provide fixed connection, and no need to
consider the power switch setting.
The nominal input impedance of 20kohms and 10kohms balanced mode in non-balanced
mode.
The pin assignment is according to the standard AES14-1992 (ANSI S4.48-1992):
Pin 1 (XLR) : GND (Ground)
Pin 2 (XLR) : (+) Non-inverted signal
Pin 3 (XLR) : (-) Inverted signal
Sensitivity mode (D)
This switch allows to set the sensitivity between 0.775V or 1.4V.
Cooling air outlet grilles (G)
Fan cooling permits airflow through the most vital parts of the amplifier. Since the airflow
finds its way out through these grilles, keep them as clean and dust-free as possible to assure
proper cooling.
Circuit breaker (E):
When amplifier is overloaded (caused by the small load impedance of the amplifier or the
continuous input signal), the button of the circuit breaker will upspring immediately, and will be
cutoff power automatically to protect the amplifier. You must exclude overload condition, and
then press the button of the circuit breaker, and the power amplifier will resume to normal
operation.
Power outlet (F)
The amplifier is provided with a socket IEC320-C14. When using the amplifier, one
should check whether the selected voltage is correct or not. If the voltage is wrong,
it could damage the amplifier. Please ensure that the device is connected to the
power supply with ground to use.

Speaker connection
Connect speakers at one or two output
Speakon connectors. See the rear panel
instructions.
Speakon connectors offer quick connection for
portable applications. To enable a Speakon
connection, plug the male connector into the
outlet and rotate it clockwise. It will then lock into
place and be ready for use.
Racking
All amplifiers are 19-inch rack mount width and
are 2U DIN in height.
Four front-panel mounting holes are provided
for use with M5 or M6 or 1/4” screws. To avoid
bending the chassis in rack mounting applications
where the rack will be transported, mount the
amplifiers to the back of the rack using the rear
mounting holes. Alternatively, place the bottom
amplifier against the base of the rack and pile the
amplifiers with no clearance in between.
A fan cools the aluminum heat sinks from front
to back.
Fan cooling permits airflow through the most
vital parts of the amplifier.
When mounting the unit onto a 19-inch rack, a
rack cooling system is not required, since the air is
exhausted out through the front grille.
However, the rack must not be sealed, and it
should at least have a large enough ventilation
grille to allow air into the rack.
Input connection
A balanced connection is recommended with
XLR connectors, but an unbalanced connection
can also be used.
Mains connection
Should check whether the selected voltage is
correct or not. If the voltage is wrong, it could
damage the amplifier.
The230 V AC version has a nominal voltage
plus minus 10%, i.e., the amplifier can operate
from 207 V to 253 V AC.
Similarly, the 115 V AC version has a nominal
voltage plus minus 10%, i.e., the amplifier can
operate from 103 V to 127 V AC.
In both cases the operating voltage will be
indicated on the back panel.
INSTALLATION
8
ON / OFF
The main power switch is a push button that
turns the amplifier on/off.
When the amplifier turns on, the power LED
and protection LED are illuminated. After a few
seconds, when the start is finished the
PROTECTION LED will go out and the amplifier
will be ready for use.
To turn the amplifier off, push the button. At
that moment the main power supply voltage and
the secondary power supply voltage will turn off
internally.
Switch your sound system on from back to
front. Thus, switch on the amplifiers last on your
sound system. Switch sound sources (CDs,
turntables) first, then your mixer, then your
processors and crossovers and finally the
amplifiers. If you have more than one amplifier,
switch them on sequentially, one at a time or use a
sequencer.
Follow the reverse order when switching off,
and switch off the amplifiers before any other
element on your sound system.
Clip LED
The clip LED should never be on continuously.
This will distort the signal and may damage the
speakers. In fact, severe clipping is an easy way of
burning a speaker's voice coil.
The amplifiers feature an automatic limiting
system that impedes prolonged saturation, but the
dynamic nature of music signals stops it from
being a brick wall protection. Thus at most, the
clip light could be lit occasionally.
Level controls
The level rotary potentiometer is used for
changing the input gain. Although related to output
power, it is not a direct representation of it. Thus,
we can have maximum output power with the gain
at mid position. Similarly, we may have the gain
controls at maximum and not have maximum
output if our source signal is not strong enough.
One way to use the volume controls is to set
them such that when the mixer's faders are at
their maximum level, we are just below clipping
level on the amplifier or clipping very occasionally.
