Solidyne D 816, User Manual, Page: 11 / 29

The private central sometimes deteriorates the rejec-
tion of the hybrid, reason why we advised to directly
connect the console to the public lines, whenever it
is possible.
The associate telephones (used generally by the
Production to answer the calls) are connected in
parallel to the lines in an external box to the conso-
le; or by means of RJ11 type “Y” adapters.
The telephone lines internally are protected against
lightings
by metallic oxide varistors (SIOV). Never-
theless, we recommend to use additionally external
line protection of good quality.
Although the console has internal protection; it is re-
commended to use external line a protection against
transient voltage peaks due to accidents or lightings.
2.2.6.2 CONNECTING A CELL PHONE
An adapter cable-interface is required to connec-
ting the CELL PHONE to the console. This connecti-
on differs according to brand
and model of the cellu-
lar. The following image shows the cellular to RJ-11
connection.
Basically, the cellular connection uses a standard
“free hands” cable purchased for that cellular model.
The console sends the program signal to the cell
phone and receives the audio from the cell phone
that enters to the D-816 through the hybrid chan-
nel . The cell phone works in a mode denominated “4
wires” different from the telephone lines (2 wires).
In almost all models, microphone and speaker dis-
connects while the cell phone is used in “free hands”
mode. Please refers to the user manual of you cell
phone for details on this way of operation.

D816 allows the user to have cellular and land
phone lines in conference
2.2.6.3 EXTERNAL HYBRID
The D-816 series has a connector with send and re-
turn from external hybrid .
“External Hybrid” uses a female TRS of ¼” (Jack)
that gives signal (PGM send) by “tip” and receives
signal (return or input to console) by “ring”.
PGM send is MIX-MINUS, that is to say, it sends all
the signals of ‘Bus' PGM, with exception of the Re-
turn from Hybrid, to avoid feedback loops.
The audio from external hybrid enters to the console
through the hybrid channel. The main FADER will
behave in the same way that with the telephone lines
connected to the console, sending the signal to the
air or the previous circuit, according to the fader po-
sition.
Connection to a computer
This I/O can be used to connect a computer to use a
VoIP software (like Skype or similar). External Hybrid
connects to the computer to the microphone input and
to the line outputs, with a special “Y” cable (¼” TRS to
two 1/8” TRS). See connection below.
