FP121 Sound Source

FP121 Sound Source
Omni-Directional Loudspeaker
Noise Generator/Amplifier AP601
Applications
• Measurement of sound insulation in
buildings and of building elements
ISO 140
• Measurement of the reverberation
time of rooms ISO 3382
• Measurement of sound absorption in
a reverberation room ISO 354
Main characteristics
• Complete omni-directional radiation
diagram
• 123 dB sound power level
• White, Pink and Pink filtered (1/3
octave band 50 – 5000 Hz) noise
generator
• Control by cable, remote control or
Bluetooth TM (internal on the AP601)
• Forced ventilation cooling system
with automatic fan turn off: Ideal for
background noise measurements
The FP121 Sound Source has two well defined parts: the
Omni-directional Loudspeaker BP012 and the Noise
Generator / Amplifier AP601.
The FP121 has been designed to satisfy the needs of
professionals specialising in building and room acoustics. The
FP121 allows you to measure airborne sound insulation,
reverberation time and sound absorption in accordance with
the standards: ISO 3382, ISO 354 and ISO 140.
The BP012 has12 loudspeakers mounted on a dodecahedral
housing. This ensures a complete omni-directional radiation
diagram; that is to say, sound is radiated in a spherical
distribution, as is required by the standards ISO 140 and ISO
3382.
The BP012 handles an electrical power of 600 W RMS
developing 123 dB of sound power level in the third octave
bands with centre frequency between 50 and 5,000 Hz. The
loudspeaker has been designed to supply the maximum power
for over an hour.
To facilitate handling the BP012 includes 5 rubber pads for
floor mounting, 1 hoisting eye for aerial suspension and 2 grips
for ergonomic handling. The BP012 is internally reinforced
with an aluminium core that makes it robust and allows it to be
adapted for the TR012 tripod.

The AP601 is comprised of a White and Pink noise generator
and a power amplifier. The AP601 has been especially
designed to generate the signal to be reproduced by the
BP012 .
Thanks to its internal noise output and its external noise input,
the AP601 can be used as a noise generator + amplifier, just
as a noise generator or just as an amplifier. Also allows you to
insert between the noise generator and the amplifier
supplementary signal processing equipments as equalizers or
compressors.
The AP601 has an overcharge, clip and thermal protection.
The AP601 can be operated directly from the keyboard,
remote control or by a PC with the included software. This
communication with the PC can be done through cable or
through Bluetooth TM , wireless.The forced ventilation cooling
system of the AP601 turns off the fan during one minute after
the signal reproduction is stopped. This is efficient for the
background noise measurements.
