PHONOGRAPH
Phonographs employing a ceramic or crystal type
cartridge may be connected to either the AUX 1 or
AUX 2 receptacle. Use single-conductor shielded
cable terminated in a standard single-prong phono
plug. It is recommended that a separate ground wire
be connected between the phono player base and the
GND terminal on the Output Terminal Strip on the rear
panel of the amplifier (see figure 2). This is not re-
quired when using the Bogen Model LPC-4 phono
player accessories.
AUXILIARY
A radio tuner, tape recorder or any other high-
level, high-impedance signal source may also be con-
nected to the AUX inputs. An input level of at least
0.3 volts is required to obtain full output from the
amplifier.
The input from a 500/600-ohm line is also con-
nected to the AUX receptacle through a WMT-1 line
matching transformer. For detailed connections, see
the instruction sheet furnished with the Bogen Model
WMT-1 accessory.
REMOTE VOLUMECONTROL
Each of the three input channels may have its
volume controlled remotely by utilizing Bogen LVP-1
and RVC-1 accessories. Remote control permits ad-
justment of volume from distances up to 2,000 feet.
The LVP-1 unit is plugged into the appropriate
REMOTE ACCESSORY SOCKET, located on the top
chassis (see figure 3). It is necessary to remove the
top section of the
amplifier
cage
to reach the accessory
sockets. This is done by loosening the two sheet
metal screws at the rear of the amplifier and lifting
the top section off.
The leads from the RVC-1 accessory are con-
nected to the MIC 1, MIC 2 or AUX terminal and G N D
on the REMOTE CONTROL PRECEDANCE strip on
the rear panel (see figure 2). Complete installation
information is contained in the instruction sheet fur-
nished with the LVP-1 and RVP-1 accessories.
