IMPORTANT NOTE

ATTENTION: This unit must be protected from dampness 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 is 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 until it has reached room temperature.
4. In the event of water or any other fluid being accidentally spilled 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 uses a 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 causes the leakage current off the machine.

The rear panel features an introduction

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 wired follows:

• 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 four amplifier channels before external line-drivers might be required to buffer the signal.

Unbalanced Input connections

To connect an input to an unbalanced source, it is possible to connect pins 1 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

Audio input and output connections

Route The signal input into any channel can be select output from any channel.

Stereo Mode 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

• channel 1 and channel 2 are bridged,
• channel 3 and channel 4 are bridged.

PC Interface
