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 verifi cation, 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. The op-
tional MiniLINK USB interface supports data storage, documentation and fi rmware updates.
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.
THD+N
Supports Total Harmonic Distortion plus
Noise (THD+N) and 2
harmonic distortion as dB value or in %.
Input level and frequency measurement
runs in parallel and the balance indicator
fi nds defective cables.
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.

Finding wrongly connected speakers is
as simple as moving ML1 into the sound
fi eld of the speaker under test and its
polarity will be displayed. The same
measurement through the XLR input is
ideal for cable tests.
Intermittent faults are often hard to
fi nd. 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 fi nding clipping amplifi ers
etc. The auto-scale and auto-trigger
functionality are normally only found
in expensive stand alone scopes.
