OPERATION MANUAL
The preamp 077 offers a variety of special functions in order to allow a personalized
configuration of the device. Most functions are adjustable in the SETUP MENUS.
RECORD OUTPUT
Through factory settings the OUTPUT REC (22) of the preamp 077 is preset to be
connected to an analog tape recorder. Meaning, the recording volume is fixed.
If required, this setting can be changed. The RECORD output can be programmed
as additional volume controllable preamp output. In this setting, it is possible to
provide a second room with music. The REC output is able to reproduce a different
source than the MAIN output and is volume controllable in itself.
To change the output from FIXED to VARIABLE you have to go to the RECORD
SETUP in submenu REC.
For specific instructions please refer to THE SETUP MENU/ RECORD SETUP.
SURROUND INPUT
Through factory settings the SURR/INPUT 6 (23) of the preamp 077 is preset as
a SURROUND input. The signal is transported directly to the MAIN output, avoiding
volume control and all amp stages.
If you prefer not to connect a surround decoder, you can use the input as regular
high-level input with volume control (like INPUT 1 to 5). Adjustment options are
available in the MAIN SETUP in submenu M-IN6.
For specific instructions please refer to THE SETUP MENUS / MAIN SETUP.
NOTICE:
In RECORD level INPUT 6 is always a regular high-level
input.

OUTPUT AMPLIFICATION
Through factory settings the entire volume of the preamp 077 is set to a maximum
amplification of +5dB (factor 1.8). This preset should be maintained if you are
operating your system with BURMESTER power amps, which have a high input
sensitivity. If you are operating the preamp 077 with power amps or active speakers
with low input sensitivity, it is possible to change the maximum amplification to
+21 dB (factor 11.2).
Adjustment options are available in the MAIN SETUP in submenu M-OUT.
For specific instructions please refer to THE SETUP MENUS/ MAIN SETUP.
NOTICE:
The RECORD level has a maximum amplification of +5dB
(factor 1.8) when set to preamp function. The amplification of the
RECORD level cannot be adjusted.
At fixed volume the signal is put through to the RECORD output without
any influence of the preamp.
