How does it work?

Power on

Use the mains switch on the back of the amplifi er to turn it on. The amplifi er will start up
immediately.
Standby
To set the amplifi er in standby mode connect it to a piece of equipment (e.g. pre amplifi er or
integrated amplifi er) featuring a 12 V trigger with the mini jack cable. The power amplifi er will go
into standby when the connected equipment goes into standby.

The display can be dimmed by pressing the Display on the back of the amplifi er. The display is
now turned off except for one LED indicating the dimmed display state. Press the button again
to exit display dimming mode.

time, please check the following:
• The ventilation around the amplifi er
• The speaker cable and cable connections for the displayed channels
• The specifi cations of the connected loudspeakers for the displayed channels
An F (for FAIL) sign will be shown in the display. One or two dots will fl ash indicating which output
stage is failing:
Turn off the amplifi er mains switch and please check the following before turning the mains on
again:
• The speaker cable and cable connections for the displayed channels
• The connected equipment for the displayed channels
• That you are not playing above the clipping area of the amplifi er
If the amplifi er keeps failing after the powering up routine, please turn off the amplifi er and
contact your dealer or national distributor.
