tific amplifiersoccupying cubicmetersof your listening room. AMP V is
our power amplifier for multi-channel setups,andin conjunction with our
high-class home theater pre amplifier MAP 1, it ismore space-saveing as
many of the surround receiver flagships. And even better: In no way more
expensive!
AMP V accomplishesthe featto combine outstanding performance and
matchless sound character with utmostcompactly dimensions.Itsfive
channelsrender recent 5.1 home cinemaspossible. With thesefeatures,
the AMP V ispredestined for home theater solutionsin particular suitable

Wether it isMozart or King Kong, AMP V mastersall itstaskswith
dedication and captivatesitsaudience withan authenticity rarely to be
experienced. Itssound isfast, vigorousand thoroughlyhonest, but simul-
taneously full of concinnity, grace and accuracy. Paired with itsconta-
giousdelight of performance, anamazinglyrealistic sound experience
arises.
AMP V representsthelasteststate of Audionet'saward-winning amplifier
technology and audiophile passion: Engineered and produced in Bochum,
Germany.
Like in all our mono and stereo power amplifiers,we consequently real-
ized Audionet'sultra linear amplifier concept in the AMP V, too. The
circuitry isdesignedto achieve exemplarylow distortion, celerity and
stability. The internal structure of the AMP V wasdeveloped inaway
that all fivechannelswork independently asfar aspossible. Only exclu-
sively selected high-grade componentsareused. Influencesharmful to
the sound quality of the amplifierhave beencompletely eliminated, and
an exemplary stability of performance isgranted.
AMP V iscontrolled and monitored by acapable microprocessor.It pro-
videsan easyhandling, comforting reliability and evenchecksthecorrect
polarization of the mainsplug. Of course,the AMP V canberemotely
controlled by the Audionet Link interface.
But before you start listening to your new Audionet AMP V, pleaseread

5.2 Speaker terminals
Now, connect your speakerstothe gold plated terminalson the back
panel. The assignmentto the respective line input isclearly indicated.
Note
· Look out for the correct connection of yourspeaker cables.Usually,
the terminalsof your speakers(1,2 ,3 ,5and 6 )are marked '+'
and '-'.The AMP V usesthe samemarks.
· Wrong speaker polarization will result in severe lossof sound qual-
ity!
Important
· Although the AMPV hasan effective protection system to pre-
vent damage to the circuits,switch off theunit while working on
the speaker and/or audio cables.
· Ifyou use2or moreamplifiersof yourAMPV for bi-amping,
pleasemakeabsolutely sure,that you removed any jumpersat
the terminalsof your speakers(pleaseconsult the user'smanual
of your speakers), before you switch on the system.Otherwisethe
speakersand/or amplifierscould suffer damage!
· The nominal loudspeaker impedance should be 4 Ohmsor higher.
· Never use force or toolstightening the terminal screws.
6 Operating
6.1 Switching on/off
Firstswitch on the AMP V usingthe mainsswitch 7 on the backpanel.
For about 2secondsthe LEDwill flashrapidly while the unit isinitial-
ized. Afterwards, the AMP V isin stand-by mode; the LED isoff.
Press power key on thefront panel to switch on the unit. The LEDon the
front panel reportsthepolarizationof mainsphasefor afew seconds(see
sections 'Mainsphasedetection')until the speaker outputsare enabled.
The AMP V isnow ready to playback music.
Toswitch off the AMP V press power keyon the front panel again. The
unit isin stand-by mode; the LED isoff.

12
Note
· During shut down procedure the LEDwillflash7times.Before you
can switch on the AMP V again, you haveto wait untilthe shutdown
procedure isfinished and the LEDif off. Donot switch off the ampli-
fier with themainsswitch 7 at the back panel during shut down pro-
cedure.
6.2 Mains phase detection
The AMP V isable todetect thecorrect polarization of the mainsplug.
After pressing the power key until the speaker outputsare enabled, the
LED will flash in different rhythms:
· If the polarization iscorrect, the LED flashesslowly: Ä___Ä___Ä…
· If you see the LEDflashing rapidly: Ä_Ä_Ä_Ä_Ä…pleaseswitch
off the unit and flip themainsplug. If you now switch on the AMP V
again, the unit should show the correct mainspolarization by a slowly
flashing LED.
6.3 Audionet Link
For your convenience,the AMPVcan becontrolled remotely byone of
Audionet'smulti-channel pre amplifiersMAP or MAP 1, aswell asone
of Audionet'sstereo pre amplifiersPREorPRE1 using the 'Audionet
Link'interface.
You only need asimple optical 'Toslink'cable to connect the'Audionet
Link'output of your Audionet pre amplifier to the 'Audionet Link'input
13 of your AMP V. Now, the AMP V will be switched on/off automati-
cally, whenyou switch on/off your pre amplifier at the front panel or by
remote control.
In caseyouwould like to automatically control further Audionet unitsin
your systemwith the 'Audionet Link'interface, pleaseconnect the
'Audionet Link'output 12 of your AMP V to the 'Audionet Link'input
of the next Audionet unit using a simple optical 'Toslink'cable.
Note
· The 'switch on'signal isissued to any further Audionet unitsdaisy
chained to the 'Audionet Link'output of your AMP V with alittlede-
lay to avoid all unitsswitching on at the same moment, which could
causean overload of your mainsfuse.
· Independently from the 'Audionet Link'interface, you can switch
on/off yourAMP V atany time byusing the power keyon the front
plate.

7 Protection system
Your Audionet AMP V isequipped with apowerful protection system
that safeguardsyour speakersand itself.
In case of an error the AMP V will report the cause in two steps. First, the
LEDon the front panel will flashthe number of theerror occurred. Just
count how often the LEDflashesand check that numberwith the follow-
ing table:
1x DC failure:
dangerousDC voltage level at the speaker output: defective pre am-
plifier, source or active crossover carrying DC
2x High frequency (HF):
high frequency oscillation, pleasecheck yourinput source
3x Overload:
short-circuit of a loudspeaker cable or speaker isdefective
4x Temperature:
do not cover the ventilation slotsof your AMP V
Press power keyat the front panel. Now, the AMP Vreportsthenumber
of the erroneouschannel. Counthow oftenthe LEDflashestoget the
