The Shure Solo-Phone Stereo Amplifiers are de-
signed specifically for high fidelity listening with head-
phones. They provide sufficient amplification and
equalization to use any fine quality magnetic phono
cartridge (such as the Shure Stereo Dynetic). Additional inputs are available to plug in a multiplex FM
tuner or a tape playback unit. Figure A shows a typical
arrangement using a turntable with a magnetic cart-
ridge and a tuner or a tape recorder.
Although primarily designed for private high fidelity
listening to records, FM, and tape, the Solo-Phones
can be used for other applications.

switched 120 volt ac outlet on the back panel for
connecting the power cord of a record changer, tuner,

or tape player. This outlet can supply up to
amperes.
1. For Phono operation connect the signal leads
from the phono cartridge to the jacks on the back
panel marked "Magnetic Phono Input."
For Tuner or Tape operation, connect the signal
leads from the tuner or tape player to the jacks on
the back panel marked "Tape or Tuner Input."
Attention must be given to the information in the
phono, tape, or tuner equipment data sheets regarding their connections for "Right" or "Left"
channel, phasing, and grounding. Ground leads
from the metal parts of the phono, tape, or tuner
equipment, and an external ground may be connected to the screw below the magnetic phono
input terminals.
2. Plug the headphones into the jack on the front
panel. Set the selector switch to the desired function. (Tape or Tuner, or Phono).
The volume control is a two-part control allowing
separate adjustment of each stereo channel to
achieve proper balance between channels. After
each channel has been adjusted, simple over-all
volume adjustments can be made by turning either
part of the dual control.
3.
Connect the Solo-Phone power line cord to the
proper ac power outlet. (See Operating Voltage
under Specifications.) Model
SA-I Solo-Phone
comes with an attached standard two-conductor
ac plug.
The Model SA-2E is supplied with a
three-conductor power line cord, but no plug. The power line
cord plug should be installed by qualified service
personnel. The brown lead should be connected
to the "live" or "hot" terminal of the plug and the
blue lead to the neutral terminal of the plug. The
greenlyellow lead is the grounding conductor and
should be connected to the ground or earth termi-
nal of the plug.
In the Model SA-2E either operating voltage is
selected by a switch on the back panel. A switch
lock plate is provided to prevent accidental switching to the 120 VAC position. This Solo-Phone is
shipped with operating voltage selector switch
locked in the 210-240 VAC position. The lock plate
can be moved from the locking position by loosening (do not remove) the screw holding the lock
plate, rotating the lock plate
90°, and retightening
the screw.
CAUTION:
Do not connect power line cord of Model
SA-2E into 210-240 volts when switched
to 120 volts.
ACCESSORY CONNECTING PLUGS
Model PK-1, a package of six connecting plugs, is
available. This package contains two phone plugs for
connecting headsets and four phono plugs for connecting cables from turntables and tuners to the
Solo-
Phone.
