NTI AUDIO MR2 MINIRATOR

A professional, hand-held, analogue audio signal generator, with balanced and unbalanced outputs and back-lit LCD display. The generator produces sinusoidal signals, swept signals (Sine, Stepped or Continuous Sweep), white and pink noise, and a polarity-test (phase check) signal. The simple controls of rotary selection, common function 'hot-keys', mute key and informative display allow fast and accurate operation in the field or laboratory. Battery (3 x AA dry or NiCd) powered with over 20 hours continuous use (typical) and selectable auto-switch-off function. For continuous operation an external DC power inlet is included. A USB interface enables firmware updates via the NTI Audio website.
The NTI POUCH (25-608) is also available.
