NTi Audio ML1 Minilyzer Handheld Analog Audio Analyzer / Meter NTi Audio

The Minilyzer ML1 is a powerful, complete audio analyzer in a palm-sized format. Its comprehensive set of easy to access measurement functions simplify the process of system verification, diagnostics and repairs of even very complex audio installations. The smart user interface aids operators of all skill levels by setting all ranges automatically and providing complete results on a single screen.

Level

Continuously measures absolute input levels either in volts, dBu or dBV and the signal frequency. Relative measurements are also supported. Connecting MiniSPL further supports basic SPL and LEQ measurements (SPL/LEQ).

THD+N

Supports Total Harmonic Distortion plus Noise (THD+N) and 2nd to 5th selective harmonic distortion as dB value or in %. Input level and frequency measurement runs in parallel and balance indicator finds defective cables.

Frequency Sweep

ML1 automatically triggers to a sweep sequence with any step width and records the frequency response. The Minirator MR2 or MR-PRO may be used as signal source. After capture all sweep data is available.

Polarity

Finding wrongly connected speakers is as simple as moving ML1 into the sound field of the speaker under test and its polarity will be displayed. The same measurement through the XLR input is ideal for cable tests.

Time Sweep

Intermittent faults are often hard to find. The time sweep records the RMS level, frequency and the THD+N value simultaneously, helping to monitor the audio signal during a long period of time for later analysis.

Scope

Provides a quick and robust look at the waveform of the balanced audio signal, quickly finding clipping amplifiers etc. The auto-scale and auto-trigger functionality are normally only found in expensive stand alone scopes.

1/3rd Octave

Analyze and improve sound systems using the 1/3rd Octave analyzer. With Pink Noise as a stimulus the frequency response of every sound system is directly visible on the Minilyzer screen. The peak frequency display supports you in feedback improvements.

vu/PPM

Do you have to supply your mix to a broadcast van? By using the vu&ppm meter with free adjustable reference levels you can provide a perfect leveled signal. The vu meter enables you to adjust your outboard equipment for a perfect compression of your sound material.

Induction Loop Measurements AFILS

The Minilyzer together with the optional MiniLINK USB interface measures induction loops AFILS according standard IEC60118. A complete measurement menu following the standard can be enabled including calibration to customer field sensors.
