Important Note
IMPORTANT NOTE
ATTENTION: This unit must be protected from damp because of the risk of fire and the
possibility of electric shocks.
1. Make sure that you have the correct mains voltage. Only operate the unit at the mains
voltage marked on the rear panel.
2. Make sure that nothing especially no metal objects are inserted into the device. This
could result in electric shock or malfunction.
3. If the unit is subjected to extreme fluctuations of temperature e.g. On being transported
from outside into a heated room, condensation can form. This unit should not be used untill
it has reached room temperature.
4. In the event of water or any other fluid being accidentally spilt on the unit switch the
unit off immediately and send it to a qualified service workshop for inspection.
5. Make sure that the unit is always well ventilated and never exposed to direct sunlight
6. Do not use sprays to clean the unit as they have a detrimental effect on the unit and could
ignite suddenly.
7. The machine use single power switch, please cut off the power before fix.
8. Please do not put the cup, vessel of flower or container above the machine, in case the
leak out water then cause the leakage current off the machine.

Front Panel
The front panel LED area includes the following indicators per channel:
1. LEVEL CONTROL
Calibrated detente potentiometers to alter the total gain of the power amplifier. In order to avoid
distortions in mixing consoles upstream, these controls should normally be positioned between 0 and
10. The calibrated markings show the additional attenuation directly.
2. MUTE LED
MUTE-Au protection under mute position.
3. CLIP/LIMIT INDICATOR
This indicator signals if the amplifier output is clipping or limiting. It has two different indication
states:
If the clip limiter is engaged, it has a short time constant, and it illuminates briefly.
If the clip limiter is not engaged, it has an increased time constant, and it illuminates for a longer period.
4. SIGNAL LED
Green SIG Indicates output signal levels in normal operating range
5. LIMIT POWER LED
When the LED lights up, the limit power function is working.
6. TEMP
This LED lights up if the limiter has been activated and the power amplifier is being operated at the
clip level. If the LED flashes briefly, this is not a cause for concern. If this LED is lit permanently, the
volume should be reduced to avoid overload damages to the connected loudspeaker systems.
7. VHF
VHF-Very High Frequency protection active ( output muted ) ( Yellow Constant )
8. CPL LED
CPL-( Orange constant with output muted ): Low impedance/Short Circuit Detection Fault
9. POWER SWITCH
Turn the unit power on or off

Rear panel features introduction
Rear panel features introduction
Rear view of 2-channel model fitted with Speakon Connectors
Two-channel model shown. Two-channel versions have VCL and Bridge Mode switches for
channel 1 and 2 only. All models have different VCL values. Functions are otherwise
identical.
6.2.2 The DIP switch features
The following features may be adjusted using the DIP
switches on the rear-panel of the amplifier. Gain -
Globally set for all channels, from +23 dB to +44 dB in 3
dB steps.
Bridge 1+2 Switches the channel pairs into bridge mode
operation An automatic -6 dB gain compensation is
applied.

Mode-Select VCL mode to either Hard or Soft operation. For channels driving sub-woofers
and low-frequency drivers, it is recommended to use the Hard setting for optimal operation.
For mid- and high-frequency drivers, always select Soft.

Audio input and output connections

BALANCED INPUT CONNECTIONS
The XLR input connectors are electronically balanced,
and wired according to the IEC 268 standard ( pin 2=
hot ). XLR input connectors should be wiredas follows:
Audio input-2-channel models
Pin 1 Ground/Shield
Pin 2 Hot (+)
Pin 3 Cold (-)
When linking the same source signal to several input channels, be aware that there
is a limit to the number of channels an output source can "drive". A typical output
sourse (e.g. a DSP crossover unit) can drive up to two amplifier channels before
external line-drivers might be required to buffer the signal.
To connect an input to an unbalanced source, it is
possible to connect pins1 and 3 in the XLR plug at the
amplifier end of the cable. However, a better method
is to connect pin 3 to the shield at the source end of the
cable, as this usually results in better hum and noise
rejection. Balanced input connections are recommended
whenever possible.

Before setting the mode, please turn off the amplifier and slide the
mode select switch to below (Picture 1) . In this mode, Channel 1
an Channel 2 operate independently (Just traditional stereo
amplifier). The signal input into channel 1 can be output from
channel 1 only, similarly, the signal input into channel 2 can be
output from channel 2 only. The many channels, one by one in
order type pushes.

Bridge Mode
Before setting the mode, please turn off the amplifier and slide the
mode select switch to above (Picture 2), channel 1 and channel 2
are bridged.At time, the signal input into channel 1 will be output
from the bridge end. On other hand, the output level control of
channel 2 should be turn down to smallest. Only the volume
control of channel 1 are used to control the volume of whole
system.
