Introduction
The SPNCWB interface combines the audio from a
telephone line, two codecs and microphones in the lo-
cal sound system to provide natural sounding telepres-
ence and audio conference meetings. A powerful AEC
(acoustic echo canceller) is provided, which converges
fast enough to follow multi-site bridging and gain pro-
portional automatic mixing without losing convergence
depth. The AEC can handle an unlimited number of mi-
crophones and will re-converge quickly enough to follow
the movement of a wireless microphone.
Three sites can be bridged into a single conference with
one SPNCWB processor. Three additional sites can be
added with another processor with signals combined
into the ASPEN matrix for extensive routing and pro-
cessing options.
The outstanding performance of the AEC is further en-
hanced with patented, seamless automatic mixing. The
automatic mixing is applied at the crosspoints in the
matrix, which allows each signal source to exhibit a dif-
ferent behavior at the system outputs. This is useful, for
example, when the signal must participate in the confer-
ence using one of several automatic mixing modes on
some outputs, and be recorded with no processing on
other outputs.
For convenience, a TCP/IP addressable Ethernet port
and built in power amplifier are included.
This manual covers hardware installation and wir-
ing and the installation of ASPEN software. Once the
processor is communicating with a computer, refer to
the Help files in the software control panel for additional
setup and configuration settings.
