1.Thanks to the fact that all electronics are built into the sphere, convenience and ease of use are unsurpassed. The lack of an external amplifier speeds up measurements, facilitates transport and eliminates the need for the largest of connecting cables. The lack of the latter also allows energy/power to be recovered that would otherwise be lost in transferring power from the amplifier to the loudspeakers.

2.The unique 16-key calibrated remote control; in addition to start/stop, it allows all regulations of the instrument even remotely, from noise selection to level adjustment. It replaces the approximate volume adjustment obtained by turning a control knob, with buttons that allow calibrated levels at known power.

3.These are the only sources on the market that come with sine sweep and impulse noise. This allows reverberation time to be measured in all possible ways

A) Interrupted noise ( Sabine)

B) Sine sweep (Hadamard + deconvolution) that allows measurements with background noise of more than 80 dB

C) Impulsive noise (Schroeder) that only takes 20 seconds to make 6 reverberation time measurements at different positions

(it replaces the clapper for free by providing superior performance without having its shortcomings).

 4. Exclusive system for choosing the best position to placethe microphone in acoustic insulation measurements between adjacent rooms.

Current regulations prescribe that the frequency response, carried out in the room where the source is located, between adjacent third octaves must not have a difference in level of more than 6 dB.

The traditional pink noise (being pseudo-random) during measurements is displayed on the sound level meter with considerable fluctuations of the various third octaves.

This does not allow for a precise instantaneous reading of the value.

Accuracy is only achieved after averaging several seconds of acquisition.

In contrast, using our exclusive ‘Fast Pink Noise’ on the sound level meter the instantaneous display is perfectly stable, without any oscillation.

This makes it immediate to assess whether adjacent third octaves show level differences of more than 6 db.

The presence of the internal equaliser further facilitates linearity in the frequency response.

Failure to comply with this requirement is sufficient to invalidate the measurement in court cases.

5.Frequency response is extended from 50 to 20,000 Hz, even in small models, without the use of a subwoofer.

6.Guarantee that the declared data is real.

7.Only noise source on the market with the possibility of extending the warranty to 5 years.

Over 20 years of experience in the construction of sound sources allow us to offer cutting-edge instruments with unsurpassed performance.  The considerable industrialisation achieved and the quantities produced allow us to apply very competitive prices
