A professional, hand-held, analogue-audio signal-analyser, with built-in microphone, balanced and unbalanced line inputs, 100 x 64 pixel back-lit LCD display and simple, menu, control buttons.

The display-screen shows menu options and measurement values, with either large-scale numerical read-out or graphic display (including frequency-response and oscilloscope). Auto-ranging algorithms provide fast, accurate readings, with a minimum of menu selections for rapid testing and analysis. A 3.5mm headphone jack-socket is also provided, for aural monitoring. Minilyzer can be used with the NTI Audio Minirator or other signal sources, such as Canford “Quick Check” test media. Battery-powered (3 x AA dry or NiCd), with over 16 hours continuous use (typical) from alkaline batteries. A carrying pouch is also available.
