  • The modular platform
    SC420 is an instrument that stands out for its power, versatility and ergonomics. It has the high performance of a Class 1 integrated sound level meter (according to IEC 61672, ANSI S1.4 and ANSI S1.43).
    USB and Bluetooth? Connectivity
    1/1 Octave Filter (OF420) - 16 Hz to 16 kHz Octave Filter Analysis and Overall Functionality and NC and NR Curves
    1/3 Octave Filter (TF420) - 10 Hz to 20 kHz 1/3-octave filter analysis and overall function
    RT Reverberation Time (RT420) - Measures 1/1 and 1/3-octave reverberation time using source cutoff and impulse response methods . Includes parametric FFT analysis (FF420) for evaluating non-linear attenuation curves and filter effects
    - FFT analysis of 10,000 lines from 0 to 20,000 Hz (2 Hz/line
  • FP122 Omnidirectional Sound Source System (BP012 Sound Source + AP602 Power Amplifier)
    ??This device consists of omnidirectional loudspeaker BP012 for acoustic measurement and amplifier AP602 for omnidirectional sound source.

    Includes 1/3 octave graphic equalizer (AP602)
    Dimensions: 350 x 300 x 150 mm (AP602)
    Lightweight: 4.75 kg (AP602) and 14.5 kg (BP012)
    Bluetooth? wireless technology incorporated
    MA001 Remote control included
    123 dB pulse Width
    Complete omnidirectional radiation pattern (BP012)
  • 123 dB SPL
    The BP012 has 12 loudspeakers mounted in a dodecahedron enclosure. This ensures a full omnidirectional radiation pattern producing up to 123 dB (PWL) SPL and pink noise in the 1/3 octave band from 50 - 5000 Hz for over an hour.

    1/3 Octave Graphic Equalizer Included
    The AP602 includes a small, lightweight white and pink noise generator, power amplifier, and 1/3 octave graphic equalizer (±10 dB) with a frequency range of 50 Hz to 5 kHz. This last item makes it unique and a pioneer on the market, as it fulfills all ISO requirements related to the level difference between adjacent 1/3 octave bands generated in the emission chamber.
