4 Audio Authority CMX-144 User Manual
Introduction
The CMX-144 is the industry’s most controllable 4x4 component video matrix, featuring multiple control interfaces, a
wide variety of video and audio inputs, and a durable, attractive design sure to compliment any equipment rack or shelf.
Capable of distributing four component, analog audio, and digital audio sources to four destinations, the CMX-144 is
perfect for simple installations in mid-sized homes and small commercial applications.
* Many Sources do not support 1080p output on component video.
When planning your system, remember
that some “1080p” sources may only offer the highest resolution on the copy protected, digital video outputs.
Similarly, some TVs are not capable of displaying a 1080p resolution, even if they accept 1080p signals.
** Breakaway switching is designed for use with component video. If the CMX-144 is used with composite video,
the composite signals will always be routed with the audio because composite video must be connected via the
digital coax pathways. Note: digital audio cannot be used if composite video is connected.
