3.4 Telephone Hybrid section
For the explanation, we define three scenarios of
working:
A) Radios without production room: A DJ or
Talent that answer itself the callings of the
audience (small stations; also used by many
radio stations outside rush hour).
B) Radios with production room: There is a
producer or telephonist that answer the calls.
C) Big stations with complex diagram of mobile
transmissions and remote communications.
The cases A and B are managed using the 2608
Hybrid’s section. The case C requires an external
digital hybrid (Solidyne DH400) connected to
2600’s modules 2602.
3.4.1 Radios without a production room
The DJ or Voice Talent answer the
callings of the audience
The mixer console telecommunication channel
manages up to 3 phone lines (one is a cell phone
linked by Bluetooth). The DJ/Talent can manage
the incoming calls unassisted.
1.
When a calling incomes, the button of the cor-
responding line blink with the ‘ring’ cadence,
and a ‘ring’ tone will hear in CUE speaker (the
level adjusts from the knob ring [15]).
2.
The hybrid’s fader [23] must be closed, in
HOLD position [24]. In this condition, the caller
hears the program mix, and the audio from the
phone line sends to the CUE circuit.
3.
To answer a call press the blinking button. The
button will light in red. For the case of cell
phone, press the button CELLULAR to trans-
fer the audio.
NOTE: it´s assumed that cell phone was paired with the
2600 (see “2.2.6 – Pair a Cell Phone”).
If two callings are taken in HOLD condition,
both will be on-air in conference mode when
the main fader is raised.
4.
To talk to the line(s), press and hold the button
TALK. This action will mute the CR speakers
and the CUE speaker . The monitoring signals
stays on headphones.
5.
To listen to the caller, release TALK and press
and hold CUE [27]. The CUE signal hears by
CUE speaker.
6.
If both TALK and CUE are pressed, the user
can talk in “full duplex” using the CR head-
phones to listen the Hybrid (since CUE
speaker will be muted).
7.
To put a calling on-air (or two calls in a confer-
ence) raise the main fader [23] until reach the
right level on VU meters.
8.
To finish a call first close the fader HYBRID
and then release the button of the line. For the
case the cell phone the call is transferred to
the cell phone, and can be re-taken by press-
ing CELLULAR once. To hang out the cell
phone, short touch the button BLUETOOTH
[21].
9.
Make a call
Each landline have an associated phone set,
which is connected to the console. (RJ11
“Phone set”). The calling makes using the as-
sociated phone set. To transfer to the console,
proceed:
•
Check the position HYBRID fader, it
must be closed (HOLD).
•
Press the button PHONE 1 or 2 accord-
ing to the line that is being used.
•
Hang out the phone set.
TAKE IN MIND
Please be careful with the on-air level of the callings.
Due to the analogical hybrids are not perfect, a brief
amount of audio sent to the line is not cancelled, re-
turns through hybrid and mixes to the direct signal
(the voice from studio). Working with normal levels
this effect is not noticeable; but using high hybrid out-
put level, the voices of the studio can be distorted (by
coloration).
A phone calling not always must achieve 0VU to
equal the loudness of the voices from the studio.
Have in mind that the LF, that carries greater energy,
is not present in the telephone line, but there is in the
voices at the studio. The lows are those that produce
greater deviation in VU-METERS. Nevertheless, for
the ear the loudness is defined by the mid rage fre-
quencies. So that if you note that VU Meter “peaks
lower” with the telephone line that with the voices
from mics on the studio, this not necessarily means
that “it’s listened lower”. On the other hand, the audio
processor of the radio will be in charge to equal both
signals, so you do not leave the VU deceives to you
when mix voices of the floor with telephone calls.
VERY IMPORTANT NOTE
Conference between land lines only are possible if
both lines are of the same public central. The lines
can be connected to the same private telephonic
central (24 or 48 volts). The conference mode IS
NOT POSSIBLE BETWEEN DIFFERENT CEN-
TRALS neither different IP converters.
