The serious audio enthusiast who has long sought a precise
method of scoping and testing his stereo components, with the
objective of achieving ultimate sound performance at all times,
will tind Pioneer's new Stereo Display, Model 80-1100, to be
the most complete instrument oi its kind tor this purpose. Here,
in one attractive, sensitive unit, is the capability tor observation
of the various stereo wave torms and a means of measuring the
various characteristics possessed by all audio instruments, in-
cluding amplifiers, tuners, speakers, cartridges, tape decks,
etc. From every technical point at view, the Model SD-1100 is
an advanced and truly versatile instrument. You may, tor ex-
ample, use the Stereo Display to observe and analyze the wave

forms oi the new 4-channel stereo systems while at the same
time measure the sound tieid characteristics at your own listen-
ing room. You can observe a stereo display, measure a voltage
level, measure a phase shitt by means of a Lissajous pattern,
measure stereo sound by observing a ditterence in level of out-
put signals, even check the frequency response of a cartridge
while playing a stereo test record. Much more, too. Pioneers
Stereo Display installs easily and with its handsome design will
complement your existing stereo equipment. Most important,
an investment in this unit will be an investment in unparalleled
sound quality.

» ~ '1', . -The SD- 1100
is equipped with a 3- inch (75mm) electrostatic deflection-
type brightness cathode- -ray tube and easy- t-o- read scale to
allow easy observation of wave forms. The pattern which you
will read will always be bright and clean, even during rapid
wave form changes. In addition, the 80-1100 features an
automatic spot killer circuit which employs the automatic
capability of reducing pattern brightness when the vertical
and horizontal amplitude is extremely reduced. This will thus
prevent degrading of fluorescent materials. For easy obser-
vation of Lissajous wave forms. the vertical and horizontal
amplifiers of the unit possess the same gain.

. ' i The sweep-automatic audio
oscillator built in to the SD-1100, when you set it to SWEEP
AUTO, may be used exclusively in an automatic sweep within
a 20-20,000Hz range in a period as short as about 25
seconds. Additionally, manual operation for sweeping the
same range is permitted (except for the SWEEP AUTO posi-
tion). The oscillator will operate on a free frequency within the
20-20,000Hz frequency range. And by varying the frequency
of output from the calibrated audio oscillator, the oscillating
frequency of the SD-1100 can be checked at each frequency
within the same 20-20,000Hz frequency range. The unit is
also equipped with a wide frequency amplifier for micro-
phone. This enables you to check the sensitivity, acoustic
frequency response and directional characteristics of your
speaker system, using an electret condenser type wide fre-
quency microphone (optional model CM-OI) for the measure-

ment and the sound field characteristics of your listening room.

. .. ' _' i :1 x The unithasa
pair of large- size level meters prominently situated in the
center of the front panel for ease of direct reading of dB
values signals. Each has a 10dB-step attenuator and a pair
of different sensitivity input terminals on front and rear panels
to enable a measurable signal to cover a range from 3mV
to 30V. These meters may be used as output level meters or
volt meters.

form observation of input signals fed from input terminals
when observing a stereo display. By setting the switch to
4-CHANNEL DISPLAY, you can easily obtain the four-channel
sound field on the cathode-ray tube screen by using 4-channel
input terminals on the back panel.

- The Stereo Display is all- transistorized,
and will thus generate only little heat The design of the unit
is attractive. All controls, meters and the cathode- -ray tube
screen are esthetically placed for maximum readibility and
operation. The SD-1100 is handsomely finished in wooden
case.
