Solidyne D 816, User Manual

Page: 10 / 29

Please do not connect a signal pin (2 or 3) to
ground. Never uses “mono plug' s” to connect the
outputs.
The nominal output level is +4 dBu @ 0VU . If you
unbalance the outputs, take in mind that the level re-
duces in 6 dB, therefore 0VU = -2dBm.
Note that if some nonprofessional equipment is con-
nected to the balanced output, may the level be too
high, causing saturation. In those cases a fixed atte-
nuator must be used to reduce the level (a resistive
splitter is a solution).
2.2.3.2 USB OUTPUTS
The output signals PGM and REC are available also
in digital format; for direct connection to a PC using
the USB ports.
This feature does not require any
additional installation. The USB recording devices
are available when connecting the USB input chan-
nels (please see “2.2.2.2 – USB digital inputs). The
channel 6 USB gives the program signal (PGM)
whereas channel 7 USB sends the recording signal
(REC).
Usually signal REC will be used for direct to hard
disk recording; whereas PGM, that is the on-air sig-
nal, finds its main utility for broadcasting of the signal
via Internet (WEB casting). For details of use the
USB outputs in Windows© please see “3,6 - Recor-
ding of programs”.
2.2.4 Monitoring outputs
2.2.4.1 HEADPHONES
There are separate outputs for study and control
room headphones; with individual level adjustment.
The Studio output has a distribution amplifier and
supports up to
eight headphones of 32 Ohms con-
nected in parallel. So that each speaker has an inde-
pendent volume control; you can use headphones
with built-in level control or; as a more professional
solution, to mount a control on the speaker’s table. A
potentiometer of 2 x 1KOhm will be right to manage
the level. In this case the level control of the console
is left to the maximum.
Next scheme is the connection for the external level
control.
2.2.4.2 MONITORS
D-816 was designed to work with active loudspe-
akers. The STUDIO
and CONTROL outputs work
with line level at 0 dBu. They have independent con-
trols for bus assignment and level. Both outputs use
female 1/8” TRS connectors.

Remember that studio monitors are muted when channels
MIC-1 or MIC-2 are opened. Control Room speakers are
muted when the button Talkback is pressed.
2.2.5 Tally
Tally output gives 12V/120 mA (2 Solidyne Air lights)
when MIC-1 and/or MIC-2 activates. Channel MIC-3
does not activate the light nor mutes the loudspe-
akers of the studio; since this channel also can ope-
rate as Line channel. Also MIC3 must be used when
the speaker/DJ operates the console from the Con-
trol Room (self-operation). In this case the control
room loudspeakers must be used with very low volu-
me to avoid feedbacks loops.
The consumption of the Tally Light output
NEVER must overpass 120 mA.
2.2.6 Telephonic Hybrid
2.2.6.1 CONNECTING STANDARD LINES
The hybrid channel manages to two land telephone
lines and one cellular phone. The internal adjust-
ments are from factory; so the user do not needs to
make adjustments.
On the rear panel there are three RJ11connectors.
Two are for the telephone lines, and the other one is
for the cell phone adapter cable.
The lines can directly be connected to public central
telephone or the local central (PBX) of the radio stati-
on.
