REFERENCE GUIDE FOR SYSTEM INTEGRATORS
Audio Sockets
Microphone Inputs
Nos. 1–3
.
Three balanced
microphone inputs for
electret microphones
balanced, 24V phantom
powered via XLR
connectors.
The phantom powering
of XLR socket No. 3 can
be switched off. The
Mic. input No. 3 will
then be a balanced line
level input.
Tip! Unused, but connected
audio inputs should be set
to Off to avoid unwanted
audio/noise.
Use Audio Input No. 4
to connect to an external
microphone amplifier or to
an external mixer.
Use Audio Input No. 5 to
connect to external playback
devices or to telephone add-on
hybrids. For systems configured
with stereo I/O, connect the
VCR/DVD left channel to this
input.
Use Audio Input No. 6 to
connect a VCR or DVD player
to the system. For systems
configured with stereo I/O,
connect the VCR/DVD right
channel to this input.
Tip! Audio inputs Nos. 5
& 6 are not equipped with
acoustic echo canceller.
Connecting microphones to
these inputs can therefore
not be recommended.
Use Audio Output No. 2 (the
AUX output) to provide a mixed
signal consisting of audio from
the local side (AUX input not
included) and audio from the
far end.
This output should be used
when connecting a telephone
add-on system.
For system configured with
stereo I/O and with SPDIF
†
active on Audio Output No. 1,
this output will provide the VCR
left channel stereo information.
For systems configured with
stereo I/O, stereo speakers and
SPDIF
† not active, this output
will provide the right channel of
the loudspeaker signal (the left
channel will be provided on the
Audio Output No. 1).
Use Audio Output No. 3
(the VCR output) to provide
a mixed signal consisting
of audio from the local side
(VCR input not included)
and audio from the far end.
This output should be used
when connecting a VCR to
the system.
For system configured with
stereo I/O and with SPDIF
†
active on Audio Output No.
1, this output will provide
the VCR right channel
stereo information.
For systems configured
with stereo I/O, stereo
speakers and SPDIF
† not
active, this output will
provide the mix of left and
right channel of the VCR
out signal.

Use Audio Output No. 1 to
provide a mixed signal of audio
from far end and local external
devices connected to input 5 &
6, in addition to dial tones.
This output should be connected
to the local loudspeaker system,
which may, or may not, include
the TANDBERG Digital Natural
Audio Module.
For systems configured with
stereo speakers and SPDIF
†
active, the left and right channel
of the loudspeaker signal will
both be provided on this output.
For systems configured with
stereo speakers and SPDIF
†
not active, the left channel of
the loudspeaker signal will be
present on this output. The right
loudspeaker channel will be
provided on Audio Output No. 2.
† SPDIF (Sony/Philips Digital Interface)
is used by the Digital Natural Audio module.
