REFERENCE GUIDE FOR SYSTEM INTEGRATORS
Microphone Inputs Nos. 1–2 .
Two balanced microphone
inputs for electret microphones
balanced, 24V phantom
powered via XLR connectors.
Use Audio Input No. 3 to
connect to external playback
devices. This input can also
be configured as a microphone
input. It will then function in
lieu of the Mic. 2 input and be
connected to Mic. 2’s echo
canceller (which can be turned
on/off).
Use Audio Input No. 4 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. This
input should be used when
connecting a telephone add-on
system.
Tip! Audio Input No. 4 is not
equipped with an acoustic
echo canceller. Connecting a
microphone to this input can
therefore not be recommended.
Use Audio Output No. 2 (the VCR output) to
provide a mixed signal consisting of audio
from the local side (VCR 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 loudspeak-
er signal (the left channel will be provided on
the Audio Output No. 1).

Use Audio Output No. 1 to provide a mixed
signal of audio from far end and local
external devices connected to input 3 & 4 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.
