Crestron CNXBRMO Bridging/Mono Interface
Bridging/Mono Interface:
CNXBRMO
Introduction
Features and Functions
• Designed for use with a Crestron® CNX-PAD8A or
CNX-BIPAD8 audio distribution processor
• Facilitates bridging of a CNAMPX-16X60 or
CNAMPX-12X60 for increased power output
• Can be configured to produce a summed, mono signal with up
to four outputs (two with inverted polarity) from a single stereo
source
Applications
The CNXBRMO accepts the stereo signal from a single room output and
splits that signal into two stereo outputs, one with normal polarity and the
other with inverted polarity. These two outputs connect to the inputs of
two adjacent stereo channels on the CNAMPX amplifier. The result is
that these two channels can be used to drive a stereo pair of loudspeakers
with over 200 Watts of output power per speaker.
On either amplifier model only the first two adjacent channels and the
last two adjacent channels are bridgeable. Therefore no more than two
CNXBRMO interfaces may be used with a single CNAMPX amplifier.
The CNXBRMO can also be configured to produce a summed mono
signal.
