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.
