NTI MiniLyzer

Minilyzer ML1 is a handheld precision analog audio meter that provides you with a comprehensive set of functions essential for the analysis of professional audio systems.

The powerful Minilyzer continuously measures the audio signal and displays the desired results with all complementary information on an illuminated hi-res graphical LC-Display.
 
The Minilyzer and the MiniSPL form a comprehensive integrating sound level meter.

MiniLINK, the USB interface for the Minilyzer allows documentation and data acquisition of all ML1 functions in conjunction with the easy to use MiniLINK PC application. MiniLINK supports online data logging up to several days. Read more about MiniLINK.

Measurement functions include:

  • Level RMS, Relative (VU) +PPM
  • Sound Pressure Level
  • Distortion Analyzer (THD+N), k2 - k5 harmonics
  • VU & PPM Meter
  • Speaker Polarity Test (for all speaker types)
  • Signal Balance Error
  • Frequency-/Time-Sweep Recording
  • 1/3rd Octave Spectrum RMS & SPLScope

pt-amg2

RDL PT_AMG-2

This portable audio instrument is comprised of a precision audio oscillator, precision level meter and speaker.

The 700 Hz oscillator section features two outputs. The balanced XLR output is front-panel switch selectable for MIC or LINE level (pro level). The unbalanced output operates at -10 dBV (consumer). Output stability is suited to accurate bench top audio testing.

The audio metering circuit features two inputs, an LED meter and a monitor speaker. The balanced input is front-panel switch selectable for MIC or LINE input (pro). The unbalanced input operates at -10 dBV (consumer). Either input may be used to feed the metering circuit. For balanced +4 dBu inputs, meter 0 dB = +4 dBu. For unbalanced inputs, meter 0 dB = -10 dBV. A front-panel volume knob controls the speaker level. The IN PHASE LED illuminates when the oscillator output and metering input are in phase (0 dB level or greater). The PT-AMG2 operates either from two internal 9 volt batteries or from an external 12 Vdc to 30 Vdc supply. Test leads and bench top support bracket are included. The balanced line levels (input and output) may be preset by the user to +4 dBu or +6 dBu.
