MAIN CONTROLS
AND SWITCHES
SELECTOR SWITCH
The selector switch selects the program source for
listening or recording. If a tape recorder's playback
output has been connected to the TAPE IN jacks
on the rear panel, you can select tape listening by
rotating the selector switch to the "T APE"
position (with the TAPE MON ITOR pushswitch in
the "out" position!.
BALANCE CONTROL
This control alters simultaneously the output level
of both channels. As the knob is turned away from
the normal 12 o'clock position, it decreases the
level in one channel, while it increasesthe level in
the other channel. (Because the balance control
knob has been set for precise electrical balance
when the pointer is at the indicator dot at the 12
o'clock position, there may be slightly greater
mechanical rotation off center in one direction
than in the other.)
VOLUME CONTROL
This is a dual control which maintains stereo
balance at all normal settings. It controls the level
of both output channels simultaneously and has no
effect on the recording outputs.
BASS, MID AND TREBLE CONTROLS
These controls are used to adjust the tonal balance
of program material to suit your individual
listening preference.

Figure 5. Front Panel Controls and Jacks
MAIN-SPKR-REMOTE SWITCH
These switches select the loudspeaker term inals to
which audio power is fed. Either the MAl N or the
REMOTE stereo pair of loudspeakers may be
operated individually, or simultaneously if both
switches are depressed. When the two MAIN-
SPKR-REMOTE switches are in the normal "out"
position, all loudspeaker terminals are internally
disconnected from the power amplifier section.
The signal at the headphones jack is not affected
by the MAIN-SPKR-REMOTE switches. The "out"
position allows "private Iistening" when stereo
headphones are used.
FRONT PANEL JACKS
DUBBING OUT
This output is internally connected in parallel with
the TAPE OUT jacks on the rear panel. Thus, any
signals available at the rear panel jacks are
simultaneously available at the front panel. You
can connect the recording inputs of an external
recorder to this jack, using a standard 3-conductor
plug. Plugs of this type have an insulated tip, an
insulated ring, and a sleeve for common return or
ground. The tip of the plug receives the left
channel of a program, and the ring receives the
right channel (see Figure 6).
DUBBING IN
This jack has a built-in switch which automatically
disconnects the rear panel TAPE I N jacks when
you insert a standard 3-conductor phone plug. It is
intended to receive the playback outputs of an
external tape recorder.
