connecting a telephone add-on
system.
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).
† SPDIF (Sony/Philips Digital Interface)
