INSTALLATION
2-1. DESK MOUNTING
To Desk Mount, install four rubber feet into the holes in
the bottom cover of the
unit. A wrap-around housing mounts into holes
in the sides of the chassis.
2-2. RACK MOUNTING
To Rack Mount, remove the top and bottom covers and install
any filler panels in the front of the adapter shelf. Mount the adapter
shelf in the rack opening from the front, securing the shelf with No. 10
screws driven from the front through the trim spacers and the rack shelf
into the rack rail. Place the units into the adapter shelf from the front
and secure with the captive fasteners installed at the rear of the shelf.
2-3. FILLER PANELS
Filler Panels are available in 1/3 and 1/2 rack widths. Mounting
is accomplished by sliding the fill panel into place in the rack chassis and
securing it in place from below with the flat head screws supplied.

AUDIO OUTPUT CONNECTIONS
The playback
driving a
600 Ohm load.
P4 provides easy access
audio output
The nominal
to the audio
is balanced with a low impedance for
output level of the playback is +8 dBm.
(see Figure 2-1).
For Monaural playback connect channel A program line to terminals
3
and 5 of output jack J4. For Stereo operation connect channel B program
line to terminals 4 and 6 of J4.
To ground the shields of the output cables at the cartridge unit
tie the external shields to pins 1 and 2 of output jack J4. If the output
shields are to be grounded at the console, no connection to pins 1 or 2
should
be made.
2-5. AUDIO INPUT CONNECTIONS
Audio Input to the Record Amplifier is by means of Input Jack J4
(see Figure 2-1). The input is high (50k Ohms) impedance bridging for
signals from -24 to +20 dBm (50 mV to 7.7 V) level. Channel A input is by
means of contacts 3 (high), and 5 (low) of J7. For Stereo, use contacts 4
(high)
and 6 (low) for channel 8 input.
