ADVANTAGES OF THE SABINE TUNER

You have purchased the world's finest electronie tuner

Some.of the features which make it even better than tuners

costing twice as much are listed here. See the following

pages for a complele discussion of these features and de-

tailed instructions on using the luner

FULLY AUTOMATIC OPERATION

Automatic Note Selection, Automatic Made Switching.

ONE-TOUCH RECALIBRATION SYSTEM

Automatically re-scale to any note from any instrument.

SUPERIOR NOISE REJECTION

Steady, accurate readings.even in a nolsy room

EXTENDED BATTERY LIFE

60 10 120 hours on a standard low-cost 9V ballery.

INDICATORS FOR ALL ESSENTIAL FUNCTIONS

DESIGN FOR EASE OF USE

Optimum Viewing Angle, Mounts for Music Stand or Amp.

ALL SOLID-STATE "'LED" DISPLAY

No broken meters. Easy to see across a dark stage.

FEATURES

Separating musical tones from voices and extraneous

noise is a complex-task requiring a sophisticated combina-

tion of analog and digital circuits. The key to high perform-

ance and low cost is Sabine's custom-design "'IC''" which

combines all of these circuits onto a single silicon chip. The

analog circuits provide the high-speed signal processing

necessary for smooth response while tracking changes in

pltch. Tuners which use only digital circuits often show the

effects of computational delay--the display will hesitate, and

jump from one reading I0 another.

FULLY AUTOMATIC OPERATION

One objective in designing this tuner was to make its use

as simple as possible, without compromising features or per-

lormance. Many of the knobs and switches lound on other

tuners control lunctions which the ST-1000 does aulomall-

cally. The musician should not have to worry about selecting

the note or setting the internal operating mode (FAST/SLOW

display respanse). The Sabine luner will automatically sense

and select any of the twelve notes in any of the seven oc-

taves C1 through B8. Once the note is sensed, mode switch-

ing is fully automatic. The mode is FAST during the inial

search far the note. Then il swilches to a MEDIUM speed

during the second or so while it is settling on a new tone.

Finally, when the circuits decide the note is "'locked in,"' the

tuner switches to SLOW mode, which provides the greatest

accuracy and minimum jitter from noise. All of this is done

without the musician having to touch a single switch,

ONE-TOUCH RECALIBRATION SYSTEM

This is a leature we are especially proud of. We thought

long and hard about what musicians really need when they

set a luner to some ather pitch than the standard A440. Most

don't really care what frequency it is, and they don't want to

figure it out by trial-and-error.with the switches. They just

want to set the tuner so it's in lune with the group, or with a

plano, or with a song on a record player, See the ""Instruc-

tions"' section for more detail.

SUPERIOR NOISE REJECTION

A Mullistage Band-Pass Filler, bullt into the custom IC,

gives outstanding separation of signal from noise, allowing

the tuner to give a steady, accurate reading, even in a noisy

room. The Sabine Tuner will track a signal 14 dB below the

noise level, far superior to any other tuner.
