About This Model
The Korg ToneWorks DTR-1 is a 1U rackmount digital chromatic tuner designed for professional stage and studio rack setups. It offers three tuning modes - Cent, Hz, and Strobe - and displays pitch deviation on a large LED meter for quick, accurate readings. Two selectable quarter-inch inputs cover electric instruments, while a built-in microphone handles acoustic sources, and a headphone output lets you monitor quietly. A handy cable check function lets you test instrument leads directly from the unit, and the reference tone generator outputs pitches across a three-octave range (C2-B4). Auto reference calibration centres on 440 Hz with a 430-450 Hz adjustment range, and a mute function enables silent tuning mid-performance.
A great opportunity to own a Korg ToneWorks DTR-1 at this price point.
