4 Installation and power supply Important · For connecting or removing loudspeakers and/or the pre amplifier your AMP III must be switched off to prevent damage on the amplifier or the connected units. · Please make sure that all cables are in absolute best conditions! Broken shields or short-cut loudspeaker cables could damage speakers and/or amplifiers. 4.1 Placement Please find a place for your Audionet AMP III that is sufficiently ventilated to allow the heat to dissipate.
Only in case of extended absence (like vacations) or if massive trouble on the mains power is to be expected you should disconnect the unit from mains. To disconnect the AMP III completely from mains pull the mains plug. 4.3 Orientation of mains plug The correct polarization of mains is important for reasons of audio clarity and stability. Please connect the mains cord that the hot pin of the wall outlet is connected to the pin of mains input 7 marked 'PHASE' 6 on the back panel of the unit.
5 Inputs and outputs Important · For connecting or removing loudspeakers and/or the pre amplifier the your AMP III must be switched off to prevent damage on the amplifier or the connected units. · Please make sure that all cables are in absolute best conditions! Broken shields or short-cut loudspeaker cables could damage speakers and/or amplifiers. 5.1 Line inputs At first, connect your pre amplifier to the line inputs 3 , 8 and 11 of the AMP III.
5.2 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.
6.2 Mains phase detection The AMP III is able to detect the correct polarization of the mains plug. After pressing the power key until the speaker outputs are enabled, the LED will flash in different rhythms: · If the polarization is correct, the LED flashes slowly: Ä___Ä___Ä… · If you see the LED flashing rapidly: Ä_Ä_Ä_Ä_Ä… please switch off the unit and flip the mains plug. If you now switch on the AMP III again, the unit should show the correct mains polarization by a slowly flashing LED. 6.
7 Protection system Your Audionet AMP III is equipped with a powerful protection system that safeguards your speakers and itself. In case of an error the AMP III will report the cause in two steps. First, the LED on the front panel will flash the number of the error occurred.
Example An error occurred. The AMP III switches off the speakers, and the LED on the front panel flashes: Ä_Ä______Ä_Ä______Ä_Ä______Ä_Ä ... According to the table above 2 flashes denote 'High Frequency Error'. Now, press the power key. The AMP III will report the channel number. The LED flashes: Ä_Ä_Ä_______Ä_Ä_Ä_______Ä_Ä_Ä ... Between the pauses, you can count 3 flashes of the LED which denotes that the error occurred in channel nr. 3 (Right). To enter stand-by mode please press the power key again.
