•
Dial the number in the cell phone and call
(SEND).
•
To transfer the call to the console, return to
the Bluetooth mode on the cell phone (see
"3.2.2.3 – Resume a call on cell phone").
•
Move the main fader TELECOM [9] to the
zone HOLD. The cell phone receives the pro-
gram signal, but remains off-air.
•
To put the calling on the air, turn "AIR LEVEL"
to the correct volume.
•
To end the call from the console, short touch
the button "BLUETOOTH". The call can also
be ended from the mobile phone screen.
NOTES
The calling can be done from cell phone without leave the
Bluetooth mode, using the console's talkback circuit.
•
The ring tone and the voice of the caller listens on CUE cir-
cuit (main fader closed in zone CUE).
•
To dialogue, use the button TALK [8] of TELECOM channel.
•
To HOLD the call, move the main fader to the zone HOLD.
•
To put the calling on-air, raise the fader to on-air zone
•
To end the call, make a short tap on button “BLUETOOTH”;
or hang-up from the cell phone.
3.2.5 Null factor
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
console. If the rejection factor is not well adjusted, it
can produce coloration of the local voices from Stu-
dio when a land line is on air. Please refer to “
2.6.1 –
Null factor”
to know how adjust the rejection factor.
3.2.6 Vox-IP communication (Skype)
Although the hybrid channel is not in charge of pro-
vides communications via Internet, we will explain
here the procedure for the communications using a
VoIP software (like Skype or similar).
REMEMBER
USB 7 CANNOT BE USED IF CHANNEL USB 6 IS NOT CON-
NECTED
; since USB 7 is slave of USB 6. Both channels can
be connected to the same computer.
WHEN TWO PCs ARE CONNECTED; CONSIDER THAT CHAN-
NEL 7 CANNOT BE USED IF THE COMPUTER CONNECTED
TO CHANNEL 6 IS OFF. Usually channel 6 is used with the
on-machine; which is operative 24 Hs.
3.2.6.1 Connection via Skype, or similar,
with a remote journalist
To make this, proceed:
a) Assign the microphones to PGM and REC.
b) In TELECOM Channel move the switch PGM-
REC to PGM.
Configure the VoIP software to use the audio de-
vices that correspond to the Channel USB-2 of
DX816/822 (typically Windows install as
USB2 audio
device
)
Make a calling with Skype or a similar software us-
ing the computer that connects to the console’s
channel
USB-2
.
During the call, the signal from the Studio micro-
phones sends to the remote location via Skype (us-
ing the bus REC). Note that when local journalists
speaking, the VU meters on PGM and REC reacts at
the same time.
The audio from remote journalist incomes to
DX816/822 via USB-2. Raising the fader of USB-2 the
Internet audio is on the air, so the local speaker and
remote caller are communicated.
3.2.6.2 Make a conference between Skype
(or similar), land lines and cell phone
The Solidyne DX816/822 allows maximum flexibility
to generate a virtual forum between journalists and
interviewees, very far apart. Proceed as follows:
1. Keep the controls like previous description a) b).
2. At TELECOM channel move the switch PGM-REC
to PGM.
Once communication is established via Skype (or
similar) you will be in the previous situation. You
may receive or generate phone calls from landlines
or a cell phone. Under this conditions, the callers
are sent to the air as usual, raising the fader of Tele-
com Channel. Now, turning on VoIP at TELECOM
channel, a return signal from the Hybrid sends to
Skype (through the REC bus). This will see reflected
in the REC VU-meter, since it will shows the TELE-
COM signal. This way everyone are in conference.
WARNING
DON'T SEND BACKGROUND MUSIC TO SKYPE. ONLY THE
MICROPHONES MUST BE ASSIGNED TO REC BUS.
Communication via SKYPE has a priority system that at-
tenuates the speaker when he is interrupted. This makes
it impossible to send the background music in the return
signal, it will cause interruptions in the audio who's talk-
ing.
Due to technical specificity of the digital telecommunica-
tion, when a conference involves lines and cell phone or
VoIP calling (Skype), the remote caller can hear an echo of
their own voice. This echo is not on the air.
