technology is an invention of Solidyne allowing restoration
of the original sound of the human voice, adding the
frequencies lost in telephone
or cellular transmission
This new technology, developed at Solidyne Labs, allows reconstructing
the original human voice quality transmitted over telephone lines or
Cellular Phone systems. This new invention, based on the Psychoacoustics
science, uses the information contained into the 300 - 3.000 Hz band
to decode it and restore to the near-original audio quality.
The Voice, once restored, has a 50-10.000 Hz bandwidth The
VQR process, in real time, with no delay, brings near-Studio audio quality.
Due to the average audio quality of receivers, about 95% of the FM audience
believes that the phone line transmission in not a remote event (that
is; the audio quality perceived is like studio quality, for them)
some ways it is a method similar to that used in Astronomy to know what
materials are formed a star by analyzing its light.
includes a 3 lines hybrid, prior to VQR system, to enable the handling
of two telephone lines and a one cell phone connected wirelessly by a
digital microwave link named Bluetooth.
All 3 lines
can be placed in conference, with a cross gain between them, to allow
for a comfortable and excellent communication level.
It also allows the direct entry of cell phones instead of phone lines.
This way saves a lot of money on telephone fares by taking advantage of
the promotions of communication at low fee, using Corporative cell phones
HL203 connects wirelessly to a cell phone through a Bluetooth microwave
digital link, that almost all cell phones possess. Then, it would not need
to perform tedious cable connections.
You do not even need to touch the cell phone, because the calls are attended
by pressing a button at the HL203.
You can keep the conversation in private (Hold mode with Cue) and sent into
the air by pressing ON-AIR
if you need to connect more cell phones, you can also do this using the
wires of hands-free kit. HL203 accepts cell phones instead of telephone
sets. You may then have up to 3 cell phones in the air in conference
of HL203 is connected by
pressing a button.
VQR technology is the only at market that
provides zero-latency (ie HAS NO DELAY)
with a near-digital audio quality
to adjust the level of quality desired.
Let's see your action:
improvement of dynamic range from 45 dB typical phone line to 70 / 80
dBA high quality Studio Microphone.
BASS: restoration of the 50 - 300 Hz band.
It is based on the vocal cord formant theory
that allows to restore the low frequency
information lost during the phone transmission
restoration of the 3.000 to 10.000 Hz band
It uses the fundamental pitch of the fricative voice sound to restore
the high harmonics
HL203 replaces in your radio a
phones are connected via a digital microwave link, Bluetooth.
This allows an audio quality much higher than today
get with a analog cable connection
of the audio signal quality is good enough, because 95% of the
radio audience believes that the sound is generated in studies.
VQR reconstruction, unlike other technologies, has no latency (Delay).
It allows for comfortable interviews from studio to remote.
HL203 is expandable like a Meccano
units can be added to bring 5 lines
and up to 7 lines, all with VQR
can connect to one or two units HL202 to expand the number of lines.
A flat cable LINK at the rear panel allows future enhancements

If you use
a Solidyne 2300 console, it is possible to add a 2330 VQR module.
This allows you to have this advanced technollogy inside the console,
with the 3 VQR controls near your hands.
LED display allows the operator to have a visual picture of the audio
