Use.
The EELA AUDIO hybrid of course can be easily interfaced with all EELA AUDIO "telephone" modules
from the S130, S340 and S440 series consoles: An incoming call is also indicated on the channel and the
hybrid can be activated (diverted) from the channel.
In the S130 series, no Auto Answer and Ready indication is possible. In the S340 and S440 consoles, the
software of this telephone channels also offers the possibility of Auto Answer.
Answering and ending a call.
An incoming call is indicated by means of a flashing LED on the front, when interfaced to a desk this
flashing can be made visible there as well by means of the "external signalling" output on the hybrid's
REMOTE connector. This call can be answered by either pressing the HYBRID ON switch on the front of
the hybrid or remote (e.g. the mixer's channel ON/OFF button) again via interfacing EXT_ON on the
REMOTE connector of the hybrid.
When interfaced to an EELA AUDIO desk, the auto-answer function of these desks will automatically
activate the hybrid after 3 call-pulses.
Make sure the fader is closed in order not to have the caller on air directly. With this fader closed it is
possible to have a pre-conversation using the TalkBack button on the channel and the PFL or COM
possibility. If the hybrid crosstalk is found poor, the caller can be asked to be silent when performing the
UPDATE procedure. Thus the digital echo canceller is re-adjusted. Now the telephone call can be brought
on air by opening the fader. It is not possible to switch off the hybrid when the fader is open as a security
not to loose a call when it is on air; first the fader has to be closed. When the fader is open it is not possible
to use the TalkBack route to talk to the caller (unless in 4-wire mode); the caller can hear the program audio
through the dedicated telephone return path.
Making a connection (outgoing call).
A connection to the caller can be established by means of an external telephoneset connected to the terminal
marked "phone". Only when the hybrid is not activated this telephoneset is looped through to the telephone
line. After the number has been dialled, the hybrid can be activated and the procedure can be followed as
described above starting at "#Make sure the fader is closed...".
