User manual SABINE STX-1500

[. . . ] Play a single tone that you wish to tune. Adjust the instrument's 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. [. . . ] Then touch the FUNCTION button on the tuner. Instantly the green IN-TUNE light will go on, indicating that the tuner now considers the piano to be in perfect tune. Now if you tune your instrument to the tuner, your instrument will be in tune with the piano. To return the tuner to standard A=440Hz, simply move the power switch to OFF and then back ON. The tuner always resets its internal scale to A=440Hz when it is turned on. EM TN N TS UR I STX1500 Features Manual Calibration The STX1500 can be calibrated to any of 12 precise frequencies ­ many more than available on other tuners. Tone Generator Generate a reference tone through an amplifier for tuning by ear. Tranposes to Any Key Transpose to any key ­ a special advantage for many band and orchestra musicians. Manual Calibration (STX1500 only) Most other tuners on the market allow the user to manually calibrate to a very limited number of pitches. However, the STX1500 can be calibrated to any of 12 precise pitches. This feature will be especially useful for tuning instruments that use open tunings, such as banjos, dulcimers, Irish harps, pedal-steel and bottleneck guitars, etc. , or any time you may wish to tune to a "natural scale" rather than an "even-tempered scale. " Example: If you wish to calibrate the tuner from standard A = 440Hz to A = 438Hz, 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 1 Hertz. ) Press the FUNCTION button when the LED corresponding to 438Hz lights. The tuner's scale is now shifted flat from A = 440Hz to A = 438Hz. Please note the manual calibration scale is referenced in Hertz and in ¢. NOTE: there are 100¢ 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 = 440Hz, simply turn the power switch to OFF and then back ON. Tone Generator (STX1500 only) The STX1500 will generate any reference tone over a two-octave range so that you may tune by ear. Example: First, plug the tuner into an 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. Press 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 raise one-half tone. [. . . ] Plucked strings go noticeably flat a few seconds after they have been plucked. Tune stringed instruments from a pitch that is flat up to the pitch you desire. This procedure removes any slack in the gears of the instrument's tuning heads. If you tune from SHARP to IN TUNE, the gears will slip as you play and the instrument will go flat. [. . . ]
