SDS – Signal Detecting
Switching
A highly desirable integration feature
called Signal Detecting Switching, or
SDS is incorporated into the Director
Matrix series. SDS enables third-
party automation systems to route
door station audio, or any voice-
activated device, into the M6800D
for distribution through residential
or commercial audio systems. Any
input channel (or stereo pair) may be
configured as the designated SDS
input, while any or all zone outputs
may be selected as announcement
or paging zones. When an incoming
audio signal is detected at the SDS
input, audio present in assigned SDS
output zones is completely muted
until the announcement has been
completed, at which time previous
signals will resume playing.
Setting up Signal Detecting Switching
is accomplished easily and quickly.
• Using a computer connected to the
same network as the M6800D, enter
the amplifier's IP address into a web
browser. If the IP address is unknown,
use an IP scanner to search for the
amplifier on the network.
• The menu will appear shown here:

• Once detected, log into the Web
Interface, select the gear icon in the
upper right corner, and open the
settings menu.
• Locate the SDS tab, and in the SDS
Input drop-down list, select the input
that will be assigned as the SDS
input. The input button will change
to orange.
• Select the Zone Outputs that will
operate for SDS, including the two
digital outputs.
• Volume levels for announcements are
adjustable in each SDS output zone.
