OUTSTANDING FEATURES OF THE RT-1601 AUTOTUNER
AUTOMATIC NOTE SENSING
The RT-1601 automatically determines and displays each note being played. The hands free operation of this tuner allows
the musician to monitor the pitch while playing.
CHR OMATIC SCALE - FULL RANGE
The RT-1601 automatically senses all 12 notes in the musical scale. Its range stretches from A0 to C6 and can be used to
tune all electronic musical instruments.
AUTOMATIC RECALIBRATION
The RT-1601 AutoTuner can be recalibrated to match the pitch of any reference instrument with the touch of a button.
EASY-TO-READ DISPLAY
The RT-1601 features a rugged solid-state LED display. The display provides a continuous indication of tuning error by
varying the LED blink rate. The (guitar) notes A B D E G are highlighted using contrasting LEDs.
QUARTZ ACCURACY
A highly stable quartz crystal oscillator assures that the Sabine AutoTuner is much more accurate than the human ear (+/-
one cent).
MANUAL RECALIBRATION
The RT-1601 can be recalibrated to any of 12 precise frequencies; many more than are available on most
other tuners.

TONE GENERATOR
The RT-1601 will generate a reference tone through an amplifier for tuning by ear.
TRANSPOSE TO ANY KEY
The RT-1601 can be transposed to any key, a special advantage for many hand and orchestra musicians.
MUTE FUNCTION FOR SILENT TUNING
The RT-1601 features a front-panel (or an optional foot pedal) mute function to cancel the unit’s output signal.
This allows the instrument to be tuned without being amplified.
RESET BUTTON
Allows the RT-1601 to be returned quickly to standard A=440 Hz without turning the power off.
TWO INPUT JACKS
The RT-1601 features two input jacks, one on the front panel and one on the back panel.
TWO OUTPUT JACKS
The RT-1601 features two output jacks, one on the front panel and one on the back panel.
9 VOLT DC ADAPTOR
The RT-1601 comes complete with a DC adaptor, hut any standard 9 Volt DC adaptor can be used. If using a
replacement DC adaptor equipped with a polarity switch, set the polarity switch so that the center pin of the DC
adaptor jack is negative as shown below.
INSTRUCTIONS FOR TUNING
I. TURN THE POWER ON.
Wait two seconds for the green light to start blinking. The green light will blink once per second to indicate that
the unit is on and ready. Electronic instruments should be connected using a standard cord ¼-inch phone jack
into the input labeled INSTRUMENT. You may connect the tuner’s AMPLIFIER jack to any amplifier or PA
system input so that you can tune as you play.
2. PLAY A SINGLE TONE THAT YOU WISH TO TUNE.
Adjust the instruments pitch until the desired NOTE INDICATOR light is lit. For example, if you wish to tune a
“D” string on a guitar, pluck the string and tune it until the “D” note indicator light is lit. Pluck the string every
second or so to keep the note “fresh” and to prevent the note from fading flat.
3. SLOWLY ADJUST THE PITCH OF THE TONE UNTIL THE GREEN “IN TUNE” LIGHT IS
LIT
Note that the SHARP and FLAT indicators blink rapidly when the tone is far from being in tune and blink slower
as the tone approaches being IN TUNE. Repeat steps 2 and 3 for the other notes until the entire instrument is
tuned.
INSTRUCTIONS FOR CONNECTION
I. Connect the musical instrument to be tuned into the front or rear jack labeled INSTRUMENT using a stan-
dard ¼-inch mono plug.
2. Connect the amplifier or PA. system input to the front or rear jack labeled AMPLIFIER using a standard ¼-
inch mono plug.
3. A floor/foot mute switch should he connected to the MUTE jack on the front panel with a standard ¼-inch
mono plug.
