User manual SABINE RT-1601

[. . . ] CHROMATIC 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. [. . . ] 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. Release the FUNCTION button when only the (MANUAL) LED is lit. 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. The tuner's scale is now shifted flat from A=440 Hz to A=438 Hz. 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. Example: First, plug the tuner into the amplifier. 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. Release the function button when the TONE OUT LED is lit. 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 may play your electric instrument while in TONE OUT mode. 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. Now, the twelve note indicator LEDs will light in sequence. 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. [. . . ] ¼-inch (one on front panel, one on back panel), connected in parallel - 25OK Ohms Impedance ­ (max input 5V peak to peak) 2 ea. ¼-inch (one on front panel, one on hack panel), direct)y connected to both inputs unless MUTE is active Specifications are subject to change without notice. CONTACT MICROPHONE (OPTIONAL) The Sabine CM-1 Contact Microphone makes tuning an acoustic instrument as easy as tuning an electric guitar. It has a removable rubber suction cup to stick the mic directly onto the instrument. The CM-1 is ideal for tuning an acoustic guitar in a noisy room or for tuning instruments that have very short tones like banjos or mandolins. [. . . ]
