The Tuner Section:
The TM-40 features a wide detection range of C1 (32.70 Hz) to C8 (4186.01 Hz) and a large LCD-type needle that delivers both the accuracy of an LCD and the excellent visibility of a needle. Its meter scale provides markings to indicate intervals of a pure major third and minor third relative to a selected pitch, plus LED indicators to show pitch deviation or blink with the tempo. Calibration is adjustable within a range of 410 to 480 Hz (in 1 Hz steps) to accommodate a variety of tuning standards .A built-in, high-sensitivity microphone makes tuning acoustic instruments easy and enhances accuracy. The optional CM-100 contact mic adds even greater precision and makes tuning in noisy environments easier.
