5.1.4 Improvement of the telephonic
reception
VQR
®
Hybrids
Solidyne VQR® technology allows restoring bass and
treble lost in the transmission. Using VQR® hybrids
at the Studios, you can narrow the gap between the
sound quality of streaming broadcasts and telephone
sound (cellular or land-line). See the user's manual
of your hybrid or console for details about VQR®.
Bluetooth links
Cell phones linked using Bluetooth have better
frequency response that is linked via a cable adapter
to hands free.
Solidyne recommend using Bluetooth connections at
both ends of the transmission chain (portable
console and hybrid at the studios).
You can find in our website (www.solidynepro.com)
audio clips and comparisons between VQR
technology and Bluetooth®, recorded in real working
conditions.
5.2 Send audio from studio
to MX2400
Streaming link is unidirectional. The MX2400 send
digital audio to the Studios. The return of audio from
Studios to the console is made via telephone
communication.
a) At the location, the reporter dialogues with the
studios using a phone connected to the
MX2400, usually a Bluetooth cell phone.
b) At the Studios , the operator receives the call
using a standard hybrid. Cell phones are
generally used at both ends, due the low cost
offered by corporate plans.
This communication occurs simultaneously and
independently of the streaming over Internet.
This telephonic return must be used only to check
the transmission is received at the Studios, and for
private communication between the on-air operator
and the MX2400.
The MX2400 operator listens the
local audio generated in the own console (PGM).
This is because the streaming have latency ; so this
signal arrives delayed from Studios to MX2400,
which cause confusion to the MX2400 users. For this
reason the at MX2400 people must listen the direct
output of the console, not the return from Studios.
Just in case that a dialogue between the Location
and Studios, the operator of MX2400 will use the
return from studios. If the latency is small (less than
0.5 seconds), does not affect the dialogue, being on
air the audio streaming while the MX2400 receives
return via cell phone.
If the delay of the streaming make difficult the
conversation, leave the streaming and send on-air
the cell phone signal. Remember that you can
improve the audio quality of phone line using
Solidyne ® VQR technology.
Another alternative, is monitoring using an external
tuner connected to input 'TUNER' on MX2400. This
way you not need the telephone link, but you lose the
possibility of private communication with the Studios
through the console (besides the fact that this
method can only be used within the coverage area of
the radio).
5.2.1 How to talk in private with the
MX2400's journalist
Some time ago, when the link was made by land-line
phone, just a phone in parallel with the line was
needed to speak with the remote operator. But when
using mobile phones connected via Bluetooth, you
must consider the talk-back circuits for hybrids and
consoles.
In the 2300 series consoles Solidyne this issue
resolved, since the hybrid signal is received directly
into the console, which has a microphone for talk-
back which the operator can talk with the MX2400
operator. This is true even for an external hybrid
connected to a console Solidyne 2300.
Some hybrids include a microphone and a
headphone output to private speak with the caller
when the line is not on-air.
In consoles that do not have a communication
system before, you should use a microphone
connected to a channel. Obviously, this channel is
sent to the hybrid but not to program. is heard by
the hybrid system prior (cue) from the standard
console.
If you works with a hybrid type Solidyne HL-203
with Bluetooth link, connected to a console that has
no talk-back circuit for the hybrid, you must
consider the cell phone used has the option to
switch between the Bluetooth device and the
phone, to transfer the calling between the hybrid
and the cell phone.
