8. SELECT Key
This key is used to select the menu that you wish to edit.
9. ENTER Key
This key is used to edit or confirm the parameter's value.
10. Power Source Socket
It is used to connect power cord after setting the proper voltage, connect one end of power cord with the unit
and another end with mains.
11. Breaker
This switch functions as fuse for protecting the unit from damage. When the unit is overloaded or the
temperature inside the unit is too high, this pushing button will spring up and break the power supply. The
power supply will be recovered after pushing this switch down again.
12. Output Connector
These connectors have two kinds: Binding post and Speak-on connector. You can choose proper connectors
according to practical need. For your safety, please be careful when do connecting work.
13. Limiter Switch
Set this switch at "ON" position, once the output level is above maximum output level, the limiter begins,
thus keeping consistent output level for protecting apparatus. If the switch is set at "OFF", the limiter function
doesn't work.
3.2 Rear Panel
These connectors connect the input signal of channel 1 and channel 2 separately.
14. Balanced Input Connectors
These two output connectors are paralleled inside with the two input connectors. It enables the unit to work under

15. Parallel Output Connectors
16. Mode Selector
Total two optional modes: Up for Stereo mode; Down for Bridge mode.
- Stereo Mode
In this mode, channel 1 and channel 2 operate independently (just as 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.You can also operate the paralleled mode via outside wiring, so, the signal input from
channel 1 or 2 will be output from both channel 1 and 2 simultaneously. Details refer to the chapter 9.
- Bridge Mode
In this mode, the signal input into channel 1 will be output from the bridged end, on the other hand, the
output level control of channel 2 should be turned down to smallest.Details refer to the chapter 9.
