The MB 2100 can be used alone or combined with the VQR technology

Technology VQR (Voice Quality Restoration) is an invention of Solidyne that allows to reconstruct the original sound of the human voice, adding the frequencies lost during the telephone transmission.

VQR operates analyzing the sound transmitted through a cellular phone or a telephone line. It searches into the reduced frequency band transmitted, for the residual information of the low frequencies eliminated by the telephone transmission. Although the ear does not listen to it, the engineers of Solidyne have found the way to detect this weak residual signal. Also, the high frequency components are found. From these weak information, it is possible to reconstruct at 80% the original sound between 50-12,000 Hertz.
Somehow is a method similar to which is used in Astronomy to know the chemical components of a star, analyzing its light. The VQR is not an audio equalizer, because it is known that it is impossible to improve the telephone sound by means of the equalization.

The reconstruction is sufficiently good, that almost all the AM radio listeners (and 95% of FM) think that the sound is generated inside the radio Studio . VQR restoration, unlike other technologies, does not have the annoying time delay that the journalists categorically reject, because the impossibility of interviewing remote people. In fact, technology VQR is totally instantaneous.

We recommend you to listen carefully the results
obtained with VQR technology (see below):

The transmission done with a MB-2100 can be received using a Solidyne HA202-VQ or a 2300 console with VQR module, to get a great sound quality on the air.

Please listen with attention the sound quality that is obtained with a MB-2100 transmitting by a GSM cell phone, or fixed telephone line, using a VQR decoder in the studio side
