How to operate the Audionet PRE

Audionets PRE is a high performance audio pre-amplifier. This
system is designed for absolutely natural music reproduction and for
highest user comfort.

The following will give you all information about how to operate your
PRE. Please read this carefully before the first use. Following these
instructions, your PRE will give you long-lasting pleasure and
satisfaction.

I) Connecting the system

Power supply

Audio sources

Inputs

Please connect the power jack (1) at the rear with your wall outlet
(Please refer to page 8). Use the provided powercable or another one
allowed for your homecountry specifications.

NOTE:

The power specifications (2) on the rear must meet to your
homecountry specifications.
The mains-button (3) at rear must be switched off.

PRE is a very sensitive system. Please ensure that all used connector
cables are in absolutely best condition.
For connecting or removing audio sources, PRE has to be switched off
(stand by-state) or must be muted.

PRE has one balanced and five unbalanced high level inputs (4). Due
to the dual mono construction, left and right inputs are separated at the
rear. Please connect left and right inputs to the corresponding outputs
of the designated high-level sources, like CD-player, D/A-converter,…

Outputs

PRE has two balanced as well as one line and one inverted unbalanced
outputs (5) for connecting power-amplifiers.
Please connect left and right channel to the corresponding inputs of
your power-amplifier. If bi-amping is desired, please use the two
balanced or the line and the inverted outputs. In the second case, you
have to change the loudspeaker polarity of the one amplifier, that is
connected to the inverted PRE-outputs (change plus to minus and
minus to plus). If you are unsure, your dealer will help you.

recording systems

To prevent any negative influence on the signal, PRE has no regular
tape monitor loop or a rec out selector.
For recording please connect the inputs of your recording system, like
DAT or tape-deck with the monitor outputs (6) of PRE. When the
recorder is connected to the monitor outputs, for playing back you
must use inputs No. 6 of the PRE.
When input No. 6 is selected and active, the monitor outputs are
always switched off. This is necessary to prevent destructive
oscillation of PRE and recorder. Therefore Input No. 6 can not be used
for a signal source, which should be recorded.
When inputs No. 1 to 5 are selected, the monitor outputs are always
on. You are free to use these inputs for playback, when the recorder is
not connected to the monitor outputs or the recorder inputs are
connected elsewhere.

Audionet-link

In combination with Audionets AMP I or / and DAC the PRE can
switch on and off the whole system. Please connect the Audionet link
(7) on the rear with a Toslink optical fibre cable to the Audionet link
of AMP I or / and DAC.

II) Switching on and off the mains

PRE is designed as a stand by-unit. To bring PRE into the stand by­state, please press the mains power switch (4) on the rear. PRE will be
in the stand by-state displaying "Audionet".
To switch off the mains is only necessary in cases of longer absence
like holidays. For switching off please press again the mains power
switch on the rear. Looking from above, the switch now shows you a
"0" and the display turns off.

NOTE:

PRE is a microprocessor controlled unit. Due to this, all systems
connected with the outputs must be off and powered down when
PRE is to be switched on or off the mains at the rear. Otherwise
PRE could destroy your power amps and loudspeaker systems.
