CHROMATIC TUNER OWNER’S MANUAL Thank you for purchasing the YAMAHA CHROMATIC TUNER TD-12. Tuning procedure Meter mode In this mode the VU style meter shown in the display is used to tune your instrument. 1. If you are using an instrument with a pickup or contact mic, connect the INPUT jack of the TD-12 to the cable (plug) from your instrument or mic. If you wish to tune your instrument using the built-in mic, do not connect a plug to the INPUT jack. In steps 4 and 5, place your instrument as close as possible to the built-in mic. * If a plug is connected to the INPUT jack, the built-in mic cannot be used. The INPUT jack is for mono use only. Stereo plugs cannot be used. 2. Press the power [ON/OFF] switch. When the power is turned on, the reference pitch defaults to A 440 Hz. When the power is on for 20 minutes without use the tuner will automatically turn off to conserve battery life. 3. If you wish to change the reference pitch (calibration), press the CALIB [ ] or [ ] switch. This can be adjusted in 1 Hz steps over a range of 410 Hz–480 Hz. 4. Play a single note on your instrument, and the name of the nearest note will appear in the display. Tune your instrument so that the correct note name is shown in the display. 5. Tune your instrument so that the VU style meter moves to the 0 position (center) and the center pitch guide LED is lit. The left indicator of the tuning guide will light if your instrument is flat, and the right indicator will light if your instrument is sharp. If you want to tune a pure major third above or a pure minor third above a certain note, make the meter indicate " " (-13.7 cents) or " " (+15.6 cents). For example if you want to tune a major third above the A (0 cents) note, set the note name display to C#, and make the meter indicate " " (-13.7 cents). Or if you want to tune a minor third above A (0 cents), set the note name display to C, and make the meter indicate " " (+15.6 cents). * While tuning with the onboard mic a quiet environment is recommended for precise tuning. Sound mode In this mode you can tune while listening to a reference pitch. 1. Make the settings described in steps 2–3 of “Meter mode.” 2. Press the [SOUND] switch to enter Sound mode. 3. Press the [SOUND] switch to select the note name you want to tune (NOTE SELECT). The pitch you hear will be one octave higher than the actual pitch of your instrument. If you press and hold the [SOUND] switch for approximately one second, A4/Bb4 and 12NOTE will alternate, and the note names that are selected when you press this switch will change. ABb: A . Bb .
