NTI MR2 Minirator Analoger Audio Signalgenerator

The MR2 is a professional, hand-held, analogue audio signal generator, with balanced and unbalanced outputs and a back-lit LCD display. The MR2 produces sinusoidal signals, swept signals (Sine, Stepped or Continuous Sweep), white and pink noise, and a polarity-test (phase check) signal. The easy to use controls of rotary selection, common function 'hot-keys', mute key and informative display allow for fast and accurate operation in the field or laboratory. Battery (3 x AA) powered with over 20 hours continuous use (typical) and selectable auto-switch-off function. For continuous operation an external DC power inlet is included. Frimware updates are avaliable on the NTI Audi Website.  

The main features of the MR2 include:

• Frequency range: 10-20,000Hz, sine; 1 digit steps
