flanges); th erejection factor of the hybrid needs to
be adjusted. See “3.2.5 Rejection factor”.
If the calling at CUE listen distorted, or with exces-
sive ambience, the level of preset CUE LEVEL [7] is
excessive. Attenuate this level until reach an opti-
mal listening of the MICs at the Studio.
3.4.2 Return level to phone line
Most of the existing telephone analog hybrids on
the market today, were designed over 30 years
ago for analogue telephone exchanges (PBX).
The Solidyne hybrids, however, have been re-
cently designed for private or public telephone
exchanges today, which are fully digital. The new
technology Hybrids are recognized because they
have no control of air return level to phone line.
This is because inside the hybrid Solidyne uses
an audio processor for return signal that includes
AGC, peak limiter & audio signal filtering. There-
fore the return is automatically adjusted during
the transmission and its level is the maximum al-
lowed by the modern digital telephone ex-
changes.
If you want to check the return level to phone
line, you must use an oscilloscope to be placed in
parallel with the telephone line and must verify
that the signal is 2 volts peak to peak.
Please note that above this level the return can
produce problems that will cause intermodulation
distortion in the audio signal that is on-air. So in
Solidyne hybrids we use a processed return
channel, to avoid distortion on-air. There are hy-
brids manufacturers that maintain the return con-
trol level as they did in the past. This allow opera-
tors to adjust "by hunch" this critic level. This
makes the voices of the reporters and inter-
viewed people distorted or with coloration.
In Solidyne keep a high grade of excellence in
the audio quality of the hybrid on-air sound. And
that quality do not depend on the operator set-
tings. Note that the Solidyne Hybrid on- air audio
quality of the local journalists is ever perfect and
without any coloration.
To achieve this level of quality we use a narrow-
band return filter. Then the return signal is limited
to the band 400 – 2.200 Hz in order not to distort
the signal to the air. This narrow band intelligibil-
ity remains high (due to processing) but occa-
sionally may seem to the remote people that it
"has little volume" because his band is narrow.
This should not worry because it is a subjective
sensation that does not affect the intelligibility of
speech.
3.4.3 HYBRID OUT (PGM/REC)
So that the communication can be on air, the
switch PGM-REC must be at the position PGM.
Please see “3.6.1 - Recording of telephone lines”.
IF YOU DO NOT HAVE AUDIO ON-AIR FROM
THE HYBRID; CHECK THE POSITION OF THE
SWITH “PGM-REC”. THIS MUST BE “PGM”
3.4.4 Using a smartphone
If the smartphone will be used with the mixer for
first time, the devices must be paired. To know
how make this refers to “2.2.6 - Pair a cell
phone”.
Once paired, the operation is the following:
•
Make sure that the main fader be closed.
•
Turns on the Bluetooth at the console, by
pressing and holding the button BLUE-
TOOTH [21] (2 seconds approximately) and
release it just when the button CELLULAR
[20] lights. The button CELLULAR remains
blinking in blue slowly to indicate that the
Bluetooth link is enabled.
•
Turns on Bluetooth at the cell phone. If the
cell phone was paired with the 2600, the link
will be established and in few seconds the
phone is linked with the mixer. In this condi-
tion, the incoming calls are transferred di-
rectly to the console.
3.4.4.1 Incoming calls
Next is detailed the use of a cell phone linked
with the console. In this condition, the operation
is similar to the seen for land lines.
•
When incomes a call, the 'ringing' listen si-
multaneously on the cell phone and on the
CUE channel.
•
To answer from the console, make a short
touch on the button “BLUETOOTH” (or an-
swer from the cell phone screen).
Once the call is answer, the operator can talk
with the caller:
•
With the main fader closed (CUE zone) the
caller listens on CUE circuit. Under this con-
dition the “PGM” send to the cell phone is
muted.
•
Press TALK [6] to dialog with the caller. It
will light in red. Press TALK again to end the
conversation.
•
Move the main fader to the zone “HOLD”.
The caller will hear the PGM signal, but is
not on-air.
