Wireless chromatic tuner which consists of 2 units, transmitter and receiver. Large backlit LCD offers excellent visibility. Newly designed meter follows even slight changes in the sound, and provides a large note name display. Internal mic allows tuning using the main unit alone. The integrated cover/stand allows the tuner to be placed on a music stand, table, or on the floor.

Main features
A compact and unique high-performance chromatic tuner.
Bright LEDs are used to display three types of tuning modes.
A wide detection range of A0--C8 (88 notes).
Calibration range of 410Hz-480Hz can be adjusted to support various concert pitches.
Built-in condenser mic lets you tune acoustic instruments.
Designed for low power consumption.
Tuning comes full circle
The DT-4 is a unique style of chromatic tuner in which LEDs around its circumference indicate how close the input pitch is to the note name displayed in the center. In spite of its compact size (fits in the palm of your hand), the illuminated circumference and large note name display provide excellent visibility, allowing high-precision tuning over a range of A0 (27.50 Hz)--C8 (4186.01 Hz). The adjustable calibration lets you specify the reference pitch in a range of 410 Hz--480 Hz (1 Hz steps). Its design emphasizes comfort and ease of use, with function-selecting switches placed for quick and easy access.
Three new tuning modes
The DT-4 illuminates the green LEDs around its circumference in one of three tuning modes: Strobe, Mirror, or Meter. There are also triangular red tuning guides that indicate whether the input is sharp or flat, helping you tune your instrument more precisely.
Strobe mode
The green LEDs will stop moving when your instrument is in tune. The LEDs will move in a clockwise direction if the pitch of your instrument is sharp, or counter-clockwise if it is flat. When the tuning is correct, the two tuning guides will also light simultaneously.
Mirror mode
Mirror mode is a new concept of tuning found only in the DT-4. When the two green LED�s at the lower left and right coincide, you're perfectly tuned. The bright green LED will move to the right of center if the input pitch is sharp, or to the left if it is flat. The distance between the bright green and dim green LED�s indicate the distance to perfect tuning.
Meter mode
Tune your instrument so that the bright green LED is aligned with the red tuning guide in the center as on a conventional needle type tuner.
Designed for easy operation and low power consumption
The DT-4 is designed for easy operation, with switches located for effortless operation when held in the palm of your hand.
In Strobe mode if approximately thirty seconds have elapsed without any input sound, the rotating red LED�s will go dark. If approximately ten minutes have elapsed with no audio input while powered-on, the DT-4 will automatically turn off to prevent unnecessary battery consumption.
