cessory “TIMER” for 2600/TM consoles. Please
see 1.4.3 – Timer / Clock for more details.
In the HD5, the “counter mode” can be disabled by
removing an internal jumper. For make this, open
the back cover of the HD5 and remove the jumper
(there is only one jumper!). This will disable the
lapsed time on-air mode, being always the current
time on display.

Solidyne VQR

(Voice Quality Restoration) is a
type of audio processing that allows improving the
audio quality of a telephone communication. This
technique bases on the reconstruction of the
spectrum lost due the transmission.
As you know, the bandwidth transmitted through a
telephone line reduces approximately to 300 Hz –
3.000 Hz, because this is the range of the human
voice. Therefore, the components of low and high
frequency, presents in the original signal, are lost
in the transmission. These components, although
are not important for the understanding of the
words, ARE VERY IMPORTANT FOR THE AU-
DIO QUALITY, because they give “weightiness”
and “presence” to the voice. System VQR really
reconstructs the bass of the voice, reaching the
frequencies of up to 50 Hertz, being able also re-
constructing component of high frequency to
recreate the highs that are of extreme importance
to obtain the
presence sensation .
In addition, stage VQR has a third control to im-
prove to the dynamic range, obtaining values of
up to 70 dBA in a telephone transmission.
This processing is applicable as much to calls by
terrestrial lines, like a calls made through the mo-
bile telephony. Although the reconstruction
reaches to callings made using the internal micro-
phones of the cellular or the fixed telephones, the
best results are obtained using a portable au-
dio console
and dynamic microphones of good
quality.
For details on VQR, you can consult the informa-
tion available in the section
“Technical Documen-
tation” on our Web site.
3.7.1 Using the VQR
Module 2630 VQR works as much with the inter-
nal hybrid of the 2600 console like with any exter-
nal hybrid; connected to the Master 2608 using
the “External Hybrid Send & Return” connections.
The module has a complete panel with luminous
level indicators that shows:
•
Degree of restoration for low frequencies.
•
Degree of restoration for high frequencies.
•
Action of the Noise Cancel
The VQR processing can be enabled or by-
passed pressing the on/off button on the module.
By pressing this button the VQR stage activates
and the MID BAND indicator lights, (or NOISE
CANCEL if the fader NOISE is open, due the ab-
sence of audio signal). With the button up the
module is by-passed and the audio of the calling
is sent on the air without processing.
The user adjusts the amount of processed signal
using the faders “Low band” and Hi Band”.
Both controls even have an ample rank of work,
making possible the processing in telephone sig-
nals whose bandwidth is very restricted.
Low band
Manages the level of lows added to the original
signal. With the fader closed there is no recon-
struction for low frequencies.
The level of reconstruction, or the amount of low
frequencies that is possible to add to the signal,
