CHROMATIC TUNER TU300
Thank you for showing your confidence in us by purchasing the BEHRINGER CHROMATIC TUNER
TU300. This compact guitar and bass tuner provides 7 different tuning modes. Thanks to its 7-segment
LED display and 11-point LED indicators, it provides great visibility, especially in dark environments.
1. CONTROLS
Top view
The ON/BATT LED illuminates when the tuner is activated. It also serves as a battery level indicator.
This LED meter indicates to what degree the instruments tone deviates from the reference tone.
These yellow arrow LEDs light up when the played note is below or above pitch. Both LEDs will
light up when the tones pitch is correct.
The 7-segment LED display indicates the string number (high E string: 1, B string: 2 etc.) of
the strummed string of your instrument, if the TU300 is operated in one of the guitar or bass
modes. In chromatic mode it displays the note name. Semitones are shown by the decimal point
LED (#) in the display.
Press the STREAM/CENT button to switch between the LED display modes (see chapter OPERATIONS).
Press the MODE button to select the tuning mode (see chapter OPERATIONS).
Use the footswitch to activate/deactivate the tuner.
Connect your guitar or bass to the 1/4" TS IN connector.
Connect your amp or another stompbox to the 1/4" TS OUT connector. When the tuner is activated
(footswitch pressed) the output is muted. This way, you can silently tune your guitar or bass.
The 1/4" TS BYPASS connector always sends a signal to your amp independently of the
footswitch position.
Use the DC IN connection at the right side of the unit to plug in a 9 V power supply (not included).
The BATTERY COMPARTMENT is located underneath the pedal cover. To install or replace the 9 V
battery, press the hinges with a ballpen and remove the pedal cover. Be careful not to scratch the unit.
+ The TU300 is powered as soon as you insert a plug into the INPUT. The battery is
disconnected when the plug is removed. For this reason, the TU300 has no on/off
switch. To extend battery life, always disconnect the INPUT when the unit is not in use.
The SERIAL NUMBER is located at the bottom.
2. OPERATION
Selecting the tuning mode: Select between 3 Guitar modes (Regular, Flat, Double Flat), 3 Bass
modes (Regular, Flat, Double Flat) and Chromatic mode.
