RECORD:
Select “ON” when recording thereby switching off TAPE INPUT.
This avoids feedback in situations where a tape recorder is
connected to both TAPE INPUT and TAPE OUTPUT. In the
“OFF” position both TAPE INPUT and TAPE OUTPUT are
active. REC ON/OFF function can also be changed without the
amplifi
er
being
in
SERVICE
MODE.
CONTRAST:
Used for adjusting the contrast in the display. Contrast can also
be
adjusted,
without
the
amplifi er being in SERVICE MODE.
CODE:
In connection with an upgrading of a LogiBit 1200 to a LogiBit
1260 it is necessary to type in a code (see also the next point
ID). After the code has been typed in, the amplifi er should be
switched off for a short period to allow the upgrading to take
effect.
ID:
Before you can receive the code used in upgrading a LogiBit
1200 to a LogiBit 1260 it is necessary to give the ID-number of
the
amplifi
er
to
your
Logia
dealer.
AUTOCAL:
In connection with a new installation, changes of the area size or
changes in the dimensions of the teleloop cable, AUTOCAL
shall be “ON” the fi rst time the amplifi er is turned on. In this
position the amplifi er calibrates with the teleloop cable. When
the calibration is fi nished AUTOCAL should be in the “OFF”
position. Thereby you avoid hearing on the teleloop the calibra-
ting signals the amplifi er uses when it is turned on. After the
amplifi er has completed its calibrating procedure for the fi rst
time, the current in the teleloop cable will automatically
be set to 1 ampere. LA VOL will be automatically set to 0 dB.
LA VOL:
Used to adjusting the current in the teleloop cable and thereby
the
strength
of
the
magnetic
fi eld. After the amplifi er has
completed its calibrating procedure for the fi rst time, the
current in the teleloop cable will automatically be set to
1 ampere. LA VOL will be automatically set to 0 dB.
BASS:
Select BASS to adjust the bass on the teleloop signal.
AGC MODE:
Menu point REMOTE allows, that the AGC-circuit can be
switched on and off via the 25 pin Sub-D port marked
CONTROL on the back panel of the amplifi er. Select “OFF” to
switch off the AGC-circuit. Under normal operating conditions,
select
“ON”,
to
activate
the
AGC-circuit.
AGC GAIN:
Used to adjust the number of required dBs that the AGC-circuit
should use to strengthen a weak signal. The AGC-circuit is able
to reduce a powerful signal with up to 20 dBs.
TREBLE:
Select TREBLE to adjust the treble on the teleloop signal.
