The FP122 Sound Source has two well defined parts: the BP012 Omni-directional Loudspeaker and the AP602 Amplifier for omni-directional sound source. The BP012 has12 loudspeakers mounted on dodecahedral housing. This ensures a complete omni-directional radiation diagram developing up to 123 dB (PWL) sound power with pink noise in third octave bands from 50 to 5000 Hz for more than an hour. The AP602 comprises in a small size and lightweight White and Pink Noise generator, a power amplifier and a 1/3 octave band Graphics equalizer (±10 dB) from 50 Hz to 5 kHz. This last item makes it unique and a pioneer in the market due it ensures ISO 140-4 requirements about the differences in level between adjacent third octave bands of sound spectrum generated in emission room. The AP602 equalizes and amplifies both external signals and white noise, pink noise or band limited 50 Hz - 5 kHz pink noise from internal generator. AP602 includes Bluetooth® wireless communication with a range of 80m and also includes the remote control MI001 for manage (on/off) the source.
