this condition, simply reverse the two leads from one channel of the
cartridge.

Tape Recorders

Tape recorders can be connected to play through and to record from
the 500-6. If the recorder has separate record and playback heads, the
DIRECT TAPE MONITOR system will permit you to listen to your
tapes while they are being recorded. and to have the full use of all
the audio control facilities of the 500-6 during ordinary playback of
previously recorded tapes. Connections are as follows:

STEREOPHONIC TAPE RECORDER:

l - Connect the Channel A or Left output of the tape recorder to the
Left Channel TAPE MON input jack.

2 -Connect the Channel E or Right output of the tape recorder to
the Right Channel TAPE MON input jack.

3 -Connect the Channel A or Left input of the tape recorder to the
Left Channel RCRDR OUT jack.

4-Connect the Channel B or Right input of the tape recorder to
the Right Channel RCRDR OUT jack.

MONOPHONIC TAPE RECORDER:

l - Connect the input of the tape recorder to the Left Channel RCRDR
OUT jack on the rear panel of the 500-6.

2 - Connect the output of the tape recorder to both the Left and Right
Channel TAPE MON jacks. You can obtain a Y" connector from
your dealer for this connection. This connection to both TAPE MON
jacks is necessary for tape playback and monitoring through both
speaker systems.

Tape Decks

A tape deck is the tape transport mechanism without the electronic
preamplifiers found in tape recorders. Such tape decks may be played
through the 500-6 by connecting the Channel A (or Left) output on
the tape deck to the jack on the 500-6 marked Left Channel TAPE
HEAD. The Channel B (or Right) output of the tape recorder should

be connected to the Right Channel TAPE HEAD jack on the 500-6.
A monophonic tape deck should be connected to both TAPE HEAD
jacks by using a Y connector, available from your dealer.

SPACEXPANDER

The FISHER Sracnxrmolt. Model K-IO. can be connected to the
500-6 by using the special SPAceanDea jacks on the top of the
chassis. Before installing the Srsczxrmnn. remove the two jumper
wires between the Sracuranusn jacks but retain the jumpers for
possible future use. These jumpers must be inserted when the
Smear/mom is not connected or the 500-6 will be completely in-
operative. Make the following connections to the Seacnxraunza:

1- LEFT T0 REVERE OUT jack on the 500-6 to the Channel A
OUTPUT jack on the SPACEXPANDBR.

2-RIGHT TO REVERE OUT on the 500-6 to the Channel B
OUTPUT jack on the Sucsxrmnm.

3-LEFT T0 REVERE IN jack on the 500-6 to the Channel A
INPUT jack on the Sracsxnnnaa.

4-RIGHT T0 REVERE IN jack on the 500-6 to the Channel B
INPUT jack on the SPACEXPANDER.

System Grounding

The GND terminal on the antenna terminal board. located on the
rear panel. is grounded to the chassis. and may be used to ground the
motor and tone arm of your record player in order to reduCe the m
sibility of hum. The chassis grounds of other components may also be
connected to this terminal. if desired.

TV Sound

Because television receivers differ widely in circuit design, it is
advisable to consult your servicemen before attempting to connect
the sound output of your TV set to the 500-6. However. once the
method of connection has been determined, the cable from the TV set
should be connected to both AUX input jacks. The sound portion of
the TV program will be heard when the Selector is turned to the
AUX-TAPE position. If you already have a tape recorder connected

closure should therefore be open at the rear. Install the chassis
above other heat-producing equipment.

The 500~C is shipped with four plastic mounting feet attached to
the bottom of the chassis. To install the 500~C in a custom cabinet.
these mounting feet must first be removed.

HORIZONTAL MOUNTING

Installation With Cleats

To provide adequate ventilation to the underside of the chassis.
it is advisable to mount the 500-C on wooden cleats which are fastened
to the floor of the cabinet. For this installation. proceed as follows:

1 -0btain a strip of wood Vt inch square and 26 inches long. Cut
this strip in half to form two 13-inch cleats.

2 - Fasten the two cleats to the top of the mounting board with wood
screws in the position shown in Figurei3. Screw heads should be flush
with the top of the cleats. Then locate and drill four 56-inch holes
through the mounting board and cleats as indicated.

3-Saw a cutout through the front panel of your cabinet to the
dimensions shown in Figure 2. The distance between the top surface
of the mounting board and the bottom of the cutout must be the same
as the height of the cleats.

4-lnsert the 500-C chassis through the front of the panel cutout.
Slide the chassis into the cabinet until the back of the control panel
is tight against the panel of the cabinet.

5- Insert the four PIS-inch screws supplied in the accessories bag
through the holes in the bottom of the mounting board and fasten
the chassis into place.

Flush Installation

If the height of the custom cabinet will not permit you to mount
the 500-6 by means of cleats, as described in the preceding section,
the chassis may be mounted directly on the cabinet shelf. If the
chassis is mounted in this way, however, it is essential that cutouts

10

be made in the shelf as shown in Figure 3. and that the back of the
cabinet remain completely open. in order to provide proper ventilation.

For a flush-mounted installation. proceed as follows:

1 - Locate and drill the four 56-inch holes in the bottom shelf of the
custom cabinet as indicated in Figure 3.

2- Saw cutouts in the bottom shelf following the outlines shown in
Figure 3. It is absolutely essential that these cutouts be made as indi-
cated so that the necessary ventilation will be supplied to the 500-C
chassis.

3 - Saw a rectangular cutout through the front panel of your custom
cabinet to the dimensions shown in Figure 2. Note that the bottom
of the cutout coincides with the top of the mounting shelf, since
cleats are not used in this installation.

4 - Insert the chassis through the custom cabinet front panel cutout.
Slide the chassis in all the way so that the rear of the 500-C control
panel fits tightly against the front of the custom panel.

5 - Fasten the chassis to the shelf by means of four mounting screws
and flat washers. The screws are inserted from the underside of the
shelf. through the holes and into the four mounting holes formerly
used for attaching the plastic mounting feet. Use the four l-inch
screws and washers furnished in the accessories bag for this purpose.
