Once answered, press the button “CELLULAR” at the
console to enter the audio. The audio enters to the con-
sole through “HYBRID” fader.
Like with the conventional lines, you can listen in previ-
ous that call; to engage in a dialog pressing TALK; to
leave waiting to the caller (HOLD) and to send the call
to the air opening the fader (AIR).
If you want to call from the cell phone, it is possible to
make the call and to connect soon the “free hands” ca-
ble to the telephone. Or it can contact with the connec-
ted telephone, listening to the audio by CUE and pres-
sing TALK to engage in a dialog (fader closed).
TAKE IN MIND
•
EXTERNAL HYBRID AND CELL PHONE CANNOT BE ON AIR
AT THE SAME TIME CELL PHONE BUTTON MUST BE RE-
LEASED IN ORDER TO USE EXTERNAL HYBRID
•
THE AUDIO FROM THE CELL PHONE IS NOT SENT TO THE
EXTERNAL HYBRID IN ANY CASE. THERE IS NO CONFE-
RENCE BETWEEN CELLULAR AND THE EXTERNAL HY-
BRID. If you need this feature, please use an external hybrid
with Cell Phone connection, like Solidyne HA204.
3.2.2 Return to phone line
Most of the existing telephone hybrids on the market
today, were designed over 30 years ago for analogue
telephone exchanges (PBX) Solidyne hybrids, howe-
ver, have been recently 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 pro-
cessor for return signal that includes AGC, peak limiter
& audio signal filtering. Therefore the return is automa-
tically adjusted during the transmission and its level is
the maximum allowed by the modern digital telephone
exchanges.
If you want to check the return level to phone line, you
must use a 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 produ-
ce problems that will cause intermodulation distortion in
the audio signal that goes to air. So in Solidyne hybrids
we use a processed return channel, to avoid distortion
at the on-air signal. There are hybrids manufacturers
that maintain the return control level as they did in the
past. This allow operators to adjust "by hunch" this cri-
tic level. This makes the voices of the reporters and in-
terviewed people distorted or with coloration.
In Solidyne obviously, we keep a high grade of excel-
lence 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 qua-
lity 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 intelligibility remains high
(due to processing) but occasionally 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 intelligibi-
lity of speech.
3.2.3
Rejection setup (Null)
This adjustment is only for LAND lines. The rejection
factor expresses the capacity of the hybrid to avoid that
the transmitted signal returns distorted to the air. Whi-
chever greater it’s this factor more “clean” will be the
sound quality of the local speaker on the air. In order
set the rejection, proceed as following:
1. Make a calling through
one
hybrid of the console.
2. Listening to the voice of the local speaker from the
PGM
monitor
, carefully turns the preset “Null” until reducing to
zero the distortion superposed to the speaker’s voice. Ple-
ase make this adjust when the console is installed.
3.2.4 Managing conferences
The conference can be made establishing the calls
from the associate telephones and sending them to the
air by pressing “Line 1” and “Line 2” on the console.
Once taken the callings in the console, you must hang
the telephones.
Let us suppose that the speaker is engaging in a dialog
with an interviewed person who called (or he was cal-
led) by the line #1; and you want to add to the conver-
sation another person. Using the associate telephone,
you make the call from the line #2. Once contacted;
press the button “line 2”. The calling will be DIRECTLY
on the air. Remember to hook the telephone.
In the same way proceed with the cell phone.
3.2.5 Vox-IP communications (Skype)
While not the hybrid channel who provides communi-
cation via Internet, we will explain here the procedu-
re for communication using VoIP software like Skype
or similar.
ATTENTION
•
USB 7 CANNOT BE USED IF CHANNEL USB 6 IS NOT
CONNECTED;
since it is slave of channel 6. Both chan-
nels can be connected to the same computer.
•
WHEN TWO PCs ARE CONNECTED; CONSIDER
THAT CHANNEL 7 CANNOT BE USED IF THE COMPU-
TER CONNECTED TO CHANNEL 6 IS
POWER OFF.
Usually channel 6 is used with the air PC; which is 24 Hs
operative.
