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.
