User manual SABINE RT-1601

[. . . ] 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. QUARTZ ACCURACY A highly stable quartz crystal oscillator assures that the Sabine AutoTuner is much more accurate than the human ear (+/one cent). [. . . ] Instantly, the green IN TUNE LED will light indicating that the tuner now considers that note to be in perfect tune. Now, if you tune your guitar to the tuner, it will be in tune with the other instrument. To return the tuner to standard A=440 Hz, simply press RESET or turn the power switch to OFF and then back ON. MANUAL RECALIBRATION Most other tuners on the market allow the user to recalibrate manually to a very limited number of pitches. However, the RT-1601 can be recalibrated to any of 12 precise pitches. This feature will be especially useful for tuning instruments which use open tunings or any time you may wish to tune to a "natural scale' rather than a "tempered scale. " Example: If you wish to recalibrate the tuner from standard A=440 Hz to A=438 Hz, press the FUNCTION button and hold until the top row of LEDs (MANUAL/FLAT, TONE OUT/IN TUNE and TRANSPOSE/SHARP) light in sequence. The bottom row of LEDs will begin to light in sequence (each LED represents I Hertz). Press the FUNCTION button when the LED corresponding to 438 Hz lights. Please note that the manual recalibration scale is referenced in Hertz and in cents. There are 100 cents between any two adjacent notes in the musical scale, and one Hertz is equal to one vibration per second. ) To return the tuner to standard A=440 Hz, simply press the reset button or turn the power switch to OFF and then back ON. TONE GENERATOR The RT-1601 will generate any reference tone over a two-octave range so that you may tune by ear. If you wish to hear a "C" note, press the function button for three seconds until the MANUAL/FLAT, TONE OUT/IN TUNE and TRANSPOSE/SHARP LEDs light in sequence. Now the "A" LED on the bottom will light and an "A" will sound through the amplifier. Each time you press the FUNCTION button, the pitch will rise one-half tone. Press the FUNCTION button three times to generate a "C" note. You will hear your instrument and the reference pitch at the same time so that you can match the tones precisely. The volume control on your instrument will also act as the volume control of the tone generator. TRANSPOSE The RT-1601 can he transposed to any key. This is especially useful if you are using a fretted instrument with a capo or if your instrument is not tuned in the key of "C", such as a "B Flat" trumpet or an "E-Flat" Alto Sax. Example: If you wish to transpose the tuner for use with a "B-Flat" trumpet, press the FUNCTION button for three seconds until the MANUAL/PLAY, TONE OUT/IN TUNE and TRANSPOSE/SHARP LEDs begin to light in sequence. Release the FUNCTION button when the LED that corresponds to TRANSPOSE is lit. Press the FUNCTION button when "A#" (which is the same as "B-Flat") is lit. The tuner's internal scale is now shifted down one full step so that a "C" played on the "BFlat" trumpet will register "C" on the tuner, not "B-Flat" as before transposing. To return to standard "C" tuning, simply press the reset button or turn the unit OFF and back ON. TUNING TIPS Most musical instruments have peculiarities that can cause annoying tuning problems. Fortunately, most of these peculiarities can he overcome by following these simple procedures. FRETTED INSTRUMENTS 1. [. . . ] Much depends on the musician's style, but generally, it is best to tune exactly as your Sabine tuner indicates.
