7. UP/DOWN Key
This key is used to move inside the menus or to modify the parameter's value.
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. Fan
The fan can accelerate the flow of air to lower the temperature inside unit.The inside temperature determines

11. Power cord
It is used to connect mains after setting the proper voltage.
12. 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.
13. 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.
14. 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.
15. Balanced Input Connectors
These connectors connect the input signal of channel 1 and channel 2 separately.
16. Parallel Output Connectors
These two output connectors are paralleled inside with the two input connectors. It enables the unit to work under
paralleled mode. Please also refer to wiring diagram for paralleled mode.
17. 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
