OPERATION MANUAL
Operating Controls
With the exception of the AC mains switch, which is located on the rear panel of the
power supply unit, all operating controls are located on the front panel of the
preamp.
AC MAINS SWITCH
The AC mains switch (33) which completely disconnects the AC power to the unit
is located on the rear panel of the 077 or on the rear panel of the external power
supply unit above the AC mains terminal. By switching to the ON position the
standby transformer is powered up.
POWER SWITCH
The POWER switch (8) switches the preamp on and off, presuming the AC mains
switch is in the ON position.
With the POWER switch (8) set to “OFF” all functions of the preamp are powered
down. Flipping the POWER switch (8) from “OFF” to “STBY”, the POWER LED (7)
lights up orange. This shows that the unit is in standby mode.
When the POWER switch is in “STBY” position the unit can be switched on and off
by pulling up the POWER switch, pushing the POWER button on the BURMESTER
remote control, the Burlink interface or by the DC IN jack.
In operating mode (ON) the POWER LED (7) lights up red and all functions of the
preamp are activated.
PLEASE NOTE:Always switch off the preamp with the POWER switch first
before bringing the AC mains switch into OFF position.
VOLUME SELECTOR
The Volume selector (6) controls the volume level in 61 steps from 00 (mute) to 60
(maximum volume) or in dB-step from MUTE to +5dB (maximum volume with LOW
amplification) or + 21dB (maximum volume with HIGH amplification). The volume
setting can be selected separately for MAIN and RECORD level. To change between
MAIN and RECORD level pull the RECORD/PHONES switch key (14) up at the or
push the MODE button on your remote control. If the REC/MAIN LED (5) lights up,
you are controlling the RECORD level.
The selected volume level will be shown in the alphanumeric display (4).
The volume selector also controls functions in the SETUP menus.
INPUT SELECTOR
With the
input selector (1)
you select the input you want to listen to. The input
selection can be done separately for MAIN and RECORD level. To change between MAIN
and RECORD level push the
RECORD/PHONES switch key (14)
up or push the
MODE
button on your remote control. If the
REC/MAIN LED (5)
lights up, you are
controlling the RECORD level, if it doesn’t light up you are controlling the MAIN level.
The selected input will be shown in the
alphanumeric display (4)
.
The input selector also controls functions in the SETUP menus.
PHASE REVERSAL
In factory settings the preamp
077
passes incoming signals without phase reversal
to the MAIN and RECORD outputs. If the pin polarity of a reproducer differs from the
pin polarity of power amps or active speakers connected to the output terminals
(see also owner `s manual PINS
2
and
3
) there is the possibility to reverse the
phase of the according input by
180
˚.
The phase reversal is activated or deactivated by pulling the switch key
PHASE/
DI SPLAY (11)
up, or by longer pressing the
DIM
button (approx.
2
seconds) on your
remote control. If the phase reversal is activated (
180
˚), the
PHASE LED (2)
illuminates.
Every input needs to be preset separately for the MAIN and RECORD level.
The presetting will be maintained.
NOTICE: Please be advised that each input can be reversed separately.
A phase reversal of the outputs is not intended.
SHIFTING BETWEEN MAIN AND REC LEVEL
All presets like input selection, volume, input level, phase shift, volume display etc.
are separately selectable. Switching between MAIN and RECORD level is done by
moving the switch key RECORD/PHONES (14) upwards or by shortly pressing the
MODE button on your remote control. When the MAIN/REC LED (5) illuminates,
the device is in RECORD level. If the LED is off, the device is in MAIN level.
DISPLAY BRIGHTNESS
By pushing the switch key PHASE/DISPLAY (11) down, or by shortly pressing the
DIM button on your remote control you can adjust the brightness of your display in
four steps from “maximum brightness” to “off”.
If modus “off” is chosen, the display illuminates when the device is operated to
indicate that a function is controlled, and dims out after a few seconds.
In modus “off”, the device shifts to maximum brightness in SETUP-mode.
The display will stay illuminated until you leave the SETUP-mode.
