5.10 Stereo Speaker Kit
(not for TANDBERG 1500 MXP and 2000 MXP)
The Stereo Speaker Kit provides an pair of floor-standing loudspeakers in addition to the built-
in DNAM . Using these speakers will enable stereo functionality in your system and thereby
enhance the sound experience.
To experience stereo sound, the stereo speakers have to be connected to the Digital Natural
Audio Module (DNAM) as well as confirming this under Stereo Settings in the main audio
menu. The stereo sound source may either be located at the far end, or locally as a sound
source (CD, DVD) connected to the codec audio 5 & 6 input pair. If using a local stereo sound
source, you also have to enable Stereo I/O mode (On) in the same audio menu, to be able to
receive stereo sound on your system, and to send stereo signals to the far end. See chapter
4.5.4 for more information.
Check also that the full-range frequency audio coding AAC-LD is enabled (In Call Quality
menu, AAC-LD is checked, and AAC-LD 128 threshold is the same or lower than the call rate
you are planning to use). See chapter
4.4.2 Audio Algorithm and 4.4.3 AAC-LD 128kbps for
more information.
An installation sheet is enclosed in the Stereo Loudspeaker Kit, which also describes
recommended physical speaker placement.
Note that if stereo speakers are enabled in the menu without having any stereo speakers
connected to the Digital NAM, or having other speakers than the TANDBERG stereo
speakers, it may cause the acoustic echo-canceller to malfunction.
