I,IPX STEREO: This position is used for the
reception of FM multiplex stereo programs with
the addition of the FISHER MPX-70 adaptot.
A stereo tape recorder or other stereo sound
source may be played through the Electra if
multiplex reception is not desired.
Ffrl snd Afrl Tuning . o o
The FM Tuning knob selects stationg in the
87.5 to l0B megacycle band, while the AM
Tuning knob selects stations in the 535 to L620
kilocycle band. Turning either knob will move
the corresponding pointer along the dial scale
to the station you wish to hear. A logging
scale, numbering 0 to 100 is included on the
dial glass between the FM and AM scales. By
using this scale as a reference, you can tune
in your favorite stations more easily the
numerical order is linear, and the gradations
are egual.
Bqss qnd Treble Controts . , .
These controls permit you to adjust the tonal
qualities of sound to your personal listening
requirements. The Bass Control varies the in.
tensity of the low frequency bass tones, while
the Treble Control varies the intensity of the
high frequency treble tones. Each Control
varies the tones for both channels simultane.
ously. To increase or decrease bass or treble
intensity, turn these knobs toward MAX or
MIN, as desired.
To listen to program material exactly as it
originates from a broadcasting studio, set these
controls to NORMAL. Thie is "flat" position,
and is equivalent to RIAA equalization. If you
leave these eontrols at NORMAL while playing
an LP or stereophonic record, RIAA equaliza-
tion will be provided automatically. (A Tape
Recorder is provided with NARTB equaliza-
tion within its own circuitry. Leaving the Bass
and Treble Controls in NORMAL position
will maintain this egualization.) It should be
remembered, however, that these controls may
be set to any position dictated by personal
listening preferences.
BqlqnceControl ..o
This control enables you to obtain equal
sound levels from each speaker system. Bal.
anced separation is important when you are
listening to stereophonic program material,
since each section of an orchestra must be
heard in its true perspective; that is, neither
section should come through any louder than
it normally would in relation to the other.
With the Balance Control pointing to NOR-
MAL, the volume at the left and right speaker
systems should be the same. Howeverr ffiy slight
imbalance that may exist - due to record char.
acteristics, differences in room acoustica etc.-
can be corrected with thie control. Simply turn
the knob slightly townrd MAX A or MAX B
to increase the volumo st tho loft or right
speaker systems, as required. You can also use
this control when you are listening to' mono-
phonic program material, since both speaker
systems are also in use.. In this case, of course,
balanced sound output is not very critical.
It should be pointed out that the Balanco
Control is not a volume control; for, aE the
level of sound is increased on one speaker
system, it is decreased on the other, maintain.
ing approximately the same overall sound ort.
put. (NOTE: you can cut ofi the sound at
either loudspeaker system by moving the con.
trol to its extreme MAX A or II,IN( B position.)
Aulomqtic Shutofi...
In order to use the automatic shutoff feature,
the AC Power switch on the control panel must
first be tumed ON. Then by turning the Auto-
matic Shutoff switch to ON, the entire Electra
will be turned off after the last record has been
played, and will lle trrrned on again as soon as
the Changer is once morc put in operation. This
feature nray lle rlel'euted lry lrrnring the switch
to OFF. Be su,re to leate thi,s sraitr:h OFIt when,

CONNECTING ADDITIONAT COMPONENTS TO THE
SOUND SYSTEM OF THE ETECTRA
In addition to listening to radio broadcasts and playing the Record Changer,
you can connect other program sources to the sound system of. the Electra, These
can include the sound from your TV set, the FISHER Spacexpancler and MPX-70
multiplex adaptor, or a stereo tape recorder (if multiplex reception is not desired).
The information that follows describes how to connect additional equipment, and
also gives the necessary control settings for proper operation. The input and output
jacks to which connections are made are located on the Tuner and Amplifier chassis,
as illustrated in Figures 2 and 3.

Tope Recorder...
A monophonic tape recorder m&y he played
through the Electra by connecting tlre recorrler
output to the AUX MONO jack on tht: 'I'uner-
Control chassis..You can record a progronr fron'r
the Electra by connecting the tape recorrler
input jack to the Channel A or B RCRDR
OUTPUT jack on the same chassis.
A stereo tape recorder may be used if the
MPX-70 multiplex adaptor is not installed in
your Electra. In this case, connect the MPX
IN PU'f jacks on the Electra to the recorder
outputs, nnd the RCRDR OUTPUT jacks on
the Electra to the recorder inputs. Be sure you
do not reverse the channels when making these
connections. To plny lrack your tapes through
the sound system of the Electra, turn the
Selector switch to MPX STEREO.
Mulriplex Stereo...
FM multiplex is a new method of trnnsrnitting
stereo broadcasts over & single FM stutiorr. In
order to receive multiplex programs in stereo
sound, the FISHER MPX-70 must be added to
the Electru, Without the addition of the MPX-
70, yolt will Irenr rnultilllex I)r'ognrrns rnono.
