Symbol Definition
The equilateral triangle containing a arrowheaded lightning symbol is intended to alert the
user of the presence of uninsulated ''angerous voltage'' within the equipment's enclosure
that may be of sufficient magnitude to constitute a risk of electric shock to persons.
The equilateral triangle containing a exclamation mark is intended to alert the user to the
presence of important operating and maintenance instructions in the literature accompanying
the appliance.
Series E products are high-performance big-power professional amplifiers which suit various
applications for sound reinforcement. The following shows the main features of Series E models.
1. High power output, big driving capacity.
2. Adoption of optimized heatsink structure and high quality cooling fans ensures system
reliability and allows the unit to run long hours with high power output.
3. Series E features interactive control over temperature of loaded impedance, power and
working voltage. Speed of the cooling fans can change automatically according to inner
temperature. When the loaded impedance is too low or the inner temperature is too high,
the equipment will adjust the power supply voltage and reduce the power supply impedance,
which helps to protect the system, and improve sound quality and reliability efficiently.
4. Low distortion
5. High slew rate helps to boost definition and achieve better sound
6. Low noise with the S/N ratio>108dB(A)
7. Frequency response: 20Hz-20KHz <+0/-0.25dB
8. 2U-rack compact design
9. E800 is specially designed for driving low impedance load, capable of driving 2 load for
a long time.

7.POWER SUPPLY
8.INPUT/OUTPUT CONNECTION
Before connecting the power amplifier to the power supply, check whether the operating
voltage (AC 220V~230V, 50~60Hz) is identical with your local power supply and confirm
that neither the power supply socket nor the power cord is damaged. Remember to pull
the cord plug out of the outlet when the unit is turned off.
Input connection
The input XLR and 1/4'' mic sockets of the same channel are linked in parallel.
Signal can be input via any input socket, output via the other socket of the same channel
and then input to another power amplifier in daisy chain mode.
Too many stages of daisy chain may affect sound quality, so do not input signals via two
interfaces of the same channel.
Output connection
The output binding post and the NL4 socket of the same channel are linked in parallel.
Do not connect both outputs of the same channel with load simultaneously.
Connect the red (hot) binding post to the positive pole of loudspeaker and the black post
to the negative pole.
Connect the output end only with load that can match the power rating and load impedance
of the power amplifier.

1. Setting of clip limiter switch
When the switch is in OFF position, the clip limiter is turned off and the limiter circuit is out
of function. Excessive signal input in such situation will easily cause clipping distortion in
output signal and loudspeaker overloading.
When the switch is in ON position, the clip limiter is turned on. When there is excessive
signal input, the limiter circuit will work automatically to adjust the total gain to reduce
distortion and control the power output without affecting the instantaneous peak output.
This function offers loudspeaker protection capability while ensuring dynamic range of music.
Switching on the clip limiter is recommended when use.
2. Setting of low cut switch
Turning the low cut switch to 50Hz position equals to add a 50Hz high-pass filter in series
into the input circuit, so signals below 50Hz will be attenuated properly, which can limit the
noneffective excursion of loudspeaker and reduce the distortion, as shown in the following
diagram.
When the low cut switch is turned to 25Hz position, it is equal to add a 25Hz high-pass filter,
which will attenuate signals below 25Hz, as shown in the following diagram.

When the low cut switch is turned to 5Hz position, all
signals within the frequency range will be amplified
accordingly, as shown in the right diagram.
1. Mode selection and signal connection
Connection diagram
Cable pin diagram
A.Stereo mode
Firstly turn the mode switch to STEREO position
on the rear panel, as shown in the picture on the
right.
In stereo mode, signals through Channel 1 and Channel
2 of the power amplifier are treated as independent
ones, which means that Channel 1 input signal will go
only to Channel 1 output, and the same is to Channel 2,
as shown in the diagram.
C.Bridged mode
Firstly turn the mode switch to BRIDGE position
on the rear panel, as shown in the picture on the right.
In bridged mode, signal can be only input via
Channel 1. Signal input via Channel 2 will not make
any sound. The positive pole of Channel 1 output
is also the positive pole of the bridged circuit. The
positive pole of Channel 2 is the negative pole of
the bridged circuit, as shown in the diagram.
To avoid electric shock that can be caused by the dangerous high output voltage, please
turn off the equipment before connecting in bridged mode!
E800 power amplifier is recommended for driving 4 load in bridged mode.
B.Parallel mono mode
Firstly turn the mode switch to PARALLEL position
on the rear panel, as shown in the picture on the right.
In parallel mono mode, signals through Channel 1
or Channel 2 of the power amplifier have the same
effect, which means that Channel 1 input signal will
go to both Channel 1 and Channel 2 outputs, and
the same is to Channel 2, as shown in the diagram.
But do not input signals simultaneously to both
Channel 1 and Channel 2.
Attention: Parallel mono mode described here is
only refered to the parallel mode of the input signals.
Please do not use the output connectors in parallel
mode.

10.OPERATION STEPS
11.DESCRIPTION OF FRONT PANEL INDICATORS
12.PROTECTION FUNCTIONS
Please follow the operation steps below when using the equipment.
1. Start the equipment
a.Set functions and do connection in accordance with the detailed information described
in item 9.
b.Check whether the output connection is short-circuited and the load impedance is too low.
c.Check whether the local voltage is identical with the operating voltage.
d.Make sure the power supply switch on the front panel is in the ''0'' position and the volume
is minimized.
e.Connect the equipment to the power supply, turn on the sound source equipment, pre-
equipment, and effectors in sequence and confirm that all work normally.
f.Turn on the power supply switch (settled at ''1'' position ).
g.Adjust the volume by turning the knob clockwise to a proper position.
2. Turn off the equipment
a. Minimize the volume by turning the knob anticlockwise.
b. Turn off the power supply switch on the front panel (to ''0'' position).
c. Turn off the pre-equipment, effectors and sound source equipment in sequence.
1. Flashing of the signal indicator indicates that there is signal output through the two channels.
2. Flashing of the peak indicator indicates that the input level is too high and the volume must
be attenuated.
3. If the peak indicator is on continuously, it indicates that the unit is in abnormal operation
condition which is possibly caused by too low impedance load, short circuit, or overheating.
The unit must be turned off for checking and debugging before being turned on again.
4. If the bridged mode indicator is on, it indicates that the power amplifier is already in bridged
mode.
E Series power amplifiers feature full protection functions which can protect the power amplifier
and loudspeaker system against damage potentially caused by short circuit, DC output or
overheating trouble.
1. Short circuit protection:
When short-circuit problem occurs in the load end, the unit will automatically switch off the
signal input therefore protect the equipment effectively.
2. DC protection:
When there is DC element in the output signal resulting from malfunction of the unit, the
unit will automatically switch off the signal output therefore effectively protect the loudspeaker
system from the potential damage caused by DC element.
3. Overheat protection:
When the temperature of the heatsink is higher than the permitted level, the temperature
sensor inside in the power amplifier will inform the protection circuit to switch off the output
automatically, therefore avoid damage to the unit and harm to the user.
