The MiniSonic MS20 is a combined oscillator and measuring set in a stand-alone unit, which is both compact and portable.

As well as being a quality tester the MS20 is a precision line-up tool, a stereo PPM, a balanced-unbalanced convertor (both ways), a stereo microphone pre-amp, a headphone amp, and a level convertor.

Automated measurements can be made through the use of Lindos sequence testing. In as little as 20 seconds, the MS20 will produce a detailed analysis of your audio equipment, and present the results on the OLED display or on your PC.

    Digitally Synthesised Oscillator
    Digitally Synthesised Oscillator
    Digitally Synthesised Oscillator
    Generates sine waves from 4Hz-40kHz in third and twelfth-octave steps at signal levels from -90dBu to +19dBu (balanced). Sequence editor mode for creating your own sequences with over 30 different test segments to choose from. 4 level and 4 frequency presets (user programmable).
    Level
    Level
    Level
    Continuously measures stereo input levels, frequency and phase. Relative measurements supported. dBSPL option provided for use with Lindos calibrated microphones. Measurements are autoranging with manual override option.
    Noise and Distortion Measurements
    Noise and Distortion Measurements
    Noise and Distortion Measurements
    Measures weighted noise and automatically mutes the oscillator. Measures 1kHz weighted distortion (ITU-R 468). Both modes are autoranging with manual override option
    Sequence Testing
    Sequence Testing
    Sequence Testing
    Automatic sequence testing for all measurement functions with optional normalisation. Additional test segments include, channel ident tones, PPM tone-burst tests and a path latency test (delay). Up to four complete sets of results can be stored in the unit for transferring to a PC.
    Frequency Sweep
    Frequency Sweep
    Frequency Sweep
    5s and 20s sweeps provided, (20Hz - 20kHz or 40Hz - 40kHz). A Lindos test CD, WAV/MP3 files, or any other Lindos audio test system can be used as the signal source. Lindos sequences use FSK (frequency shift keying) tones to syncronise the oscillator and measuring set over the audio path.
    Phase, Long Noise and Headroom Plot Test Segments
    Phase, Long Noise and Headroom Plot Test Segments
    Phase, Long Noise and Headroom Plot Test Segments
    Plots phase against frequency above 1kHz. Level against level from 0dBu - +19dBu, ideal for checking levels to the IEC limit of +18dBu. Noise against time over a 20 second period, great for spotting digital errors.
    PPM (IEC 268 type II) (BBC UK Standard)
    PPM (IEC 268 type II) (BBC UK Standard)



    PPM (IEC 268 type II) (BBC UK Standard)
    Features stereo PPM with fast-attack and dual-speed options for analysing signal dynamics. Stereo gain controlled loop-through output - ideal for setting levels in video post-production, or for field-recording.

    Lin4WinXP Software Included

  • Complete remote control of all functions, without restricting operation from the MiniSonic’s front panel.
  • Results management with simple cut and paste facilities for exporting text and vector graphs to windows applications.
  • Tolerances can be applied to any set of results providing pass/fail indication on each result.
  • Capture button that prints a single measurement line to the results sheet. This is extremely useful when testing equipment manually where results would normally be written by hand.
  • Recording controls for logging a series of measurements of the currently selected function. A graph of the incoming level against time can also be displayed for monitoring peaks on music etc.
  • Procedure testing allows a user-defined series of measurements to be logged automatically – ideal for complex production testing.
  • Programmable tone bursts.
  • Graph options window allows complete customisation of all graphs.
  • Ability to publish results to our online test results database or save them in HTML format for your own website.


  • Microphone Use   

    The Lindos precision calibrated electret microphones can be used in all measurement modes as well as for recording with the ultimate quality that only 1/4" microphones (with their freedom from high frequency directionality, interference patterns, and ringing) can make possible.

    Calibration is such that 100dB SPL reads 0dB on level +-0.5dB at 1kHz, making accurate measurements of monitor level and frequency response possible. The MiniSonic's sweep segments, with automatic triggering from the sound (no other connection needed) can be used to plot frequency response or rooms, speakers and other microphones. Echoes may interfere at bigger distances. Acoustic noise levels can also be measured to low levels for comparing noise from air conditioning, computer fans etc; and of course, electret microphone noise levels can be measured directly.
