Speaker terminals
Now, connect your speakers to the gold plated terminals on the back
panel. The assignment to the respective line input is clearly indicated.
Note
·
Look out for the correct connection of your speaker cables. Usually,
the terminals of your speakers are marked '+' and '-'. The AMP III
uses the same marks.
·
Wrong speaker polarization will result in severe loss of sound quality!
Important
·
Although the AMP III has an effective protection system to pre-
vent damage to the circuits, switch off the unit while working on
the speaker and/or audio cables.
·
The nominal loudspeaker impedance should be 4 Ohms or higher.
·
Never use force or tools tightening the terminal screws.

Operating
6.1
Switching on/off
First switch on the AMP III using the mains switch 5 on the back panel.
For about 2 seconds the LED will flash rapidly while the unit is initial-
ized. Afterwards, the AMP III is in stand-by mode; the LED is off.
Press power key on the front panel to switch on the unit. The LED on the
front panel reports the polarization of mains phase for a few seconds (see
sections 'Mains phase detection') until the speaker outputs are enabled.
The AMP III is now ready to playback music.
To switch off the AMP III press power key on the front panel again. The
unit is in stand-by mode; the LED is off.
Note
·
During shut down procedure the LED will flash 7 times. Before you
can switch on the AMP III again, you have to wait until the shut
down procedure is finished and the LED if off. Do not switch off the
amplifier with the mains switch 5 at the back panel during shut
down procedure.
