Minilyzer - Portable Analog Audio Analyzer with MiniLINK USB Interface


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. An optional USB interface supports data storage, documentation and firmware updates.

MiniLINK - the optional USB interface and PC Software for the Minilyzer ML1 and Digilyzer DL1 puts the Minstruments into a new league of affordable measurement tools. MiniLINK is pre-installed in all Acoustilyzer AL1.

MiniLINK allows documentation and data acquisition of all ML1/AL1/DL1 functions. In conjunction with the new firmware for Minilyzer (release 3.xx) and Digilyzer (release 2.xx) the instruments are able to store and transfer screen shots and measurement data for post processing.

MiniLINK is an upgradeable kit for all existing and new Minilyzers and Digilyzers. It consists of a small plug-in USB interface board that can be easily installed without any tools.

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

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

Frequency Sweep
ML1 automatically triggers to a sweep sequence with any step width and records the frequency response. The MR1, a test CD or any other stepped sweep may be used as signal source. After capture all sweep data is available.

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.

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. P>

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

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 levelled signal. The vu meter enables you to adjust your outboard equipment for a perfect compression of your sound material.
