First Startup
PLEASE NOTE:
Before connecting the unit, please check if the input
voltage data on the rear panel, underneath the AC mains terminal (32)
is equal to the local voltage of your wall outlet.
In case of doubt contact a licensed electrician or your power supply
company.
With external power supply: Connect both components with the multi-pin
•
power cord. To do this, plug any of the two ends (watch out for the guided grove)
of the cord carefully into the POWER SUPPLY terminal (16) of the preamp and
screw down the connector.
•
With external power supply: Use the same procedure to connect the other end
into the POWER SUPPLY terminal (34) of the power supply unit.
•
Connect your preferred in- and outputs of the preamp with your HiFi system.
Please refer to the chapter CONNECTIONS.
•
Make sure, that the AC mains switch (33) on the rear panel of the 077 or on the
external power supply unit is set to OFF position.
Connect the AC power cord into the AC mains terminal (32) and plug it into the
•
wall outlet.
•
Switch the AC mains switch (33) to ON position.
With the POWER switch (8) on the front panel the unit is switched on.
•
Detailed information about the manifold functions of the preamp, are available
•
in the following chapters of this owner's manual.

Connections
THE "SIMPLE" PREAMP - FACTORY SETTINGS
All connection terminals are located on the rear panel. While connecting the
preamp, all components of the music system must be turned off.
Through factory settings a lot of functions are disabled to operate the 077 as
a simple preamp. With the menus you are comfortably able to activate the
numerous options the 077 offers. In daily use these functions are hidden.
If wanted, factory settings can be reestablished.
INPUTS
To connect source components like CD-Player, FM-Tuner, Tape deck etc. the
standard version of the preamp provides five balanced inputs (XLR) named
INPUT
1
to INPUT
5
(
24
) and one unbalanced module input (RCA) named
INPUT LINE (
25
). For the best sound we recommend using the balanced inputs
whenever possible.
Instead of the LINE module the preamp may be equipped alternatively with
Phono MC module, Phono MM module or with a D/A converter module.
The pinning of the balanced inputs is: PIN1=GND, PIN2=NEG, PIN3=POS.
SURROUND INPUT
The two front channels (right front / left front) of a surround sound processor or
decoder must be connected to the INPUT 6/SURR (23). In this configuration the
signal is sent directly to the MAIN outputs (not to the RECORD outputs), bypassing
volume control. Therefore connect only components with their own volume
control to the SURROUND input!
This input allows the easy integration of surround sound components into an
existing two- channel hifi system.
The SURROUND input cannot be selected over the RECORD level.
The pinning of the SURROUND input is: PIN1=GND, PIN2=NEG, PIN3=POS.
NOTICE:
Never connect a unit to this input without its own volume
control. Serious damage to your ears and equipments may occur.
