CMX3838A2 is not your average audio switch.
With over 1 TeraMACs DSP performance, it can process up to 38 audio streams
simlultaneously. CMX3838A2 features full DSP audio on all signal types (analog,
digital coax, digital optical). This includes industry leading features
such as audio delay for lip sync correction, analog to digital conversion, input
gain, output volume, treble/bass control, and balance. Everything is
performed using the highest quality DSP algorithms yielding CD quality sound or
better on all outputs.
The entire CMX A2 product line offers unmatched upgrade
The CMX3838A2 has the following features
CMX3838A2 can be controlled by several methods, you can choose the
one the best fits your home theater control scheme.
Intelligent audio switching
CMX3838A2 automatically solves all the headaches of dealing
with multiple audio formats. Our real time algorithms detect audio
activity and format on the fly, automatically adjusting your output to always
give you the best signal possible.
Audio delay control
Audio video delay mismatch is the single
largest problem in today's home theaters. Scientific studies have shown
that even slight mismatches cause major viewer dissatisfaction and annoyance.
In fact, the majority of viewers preferred watching 480p material with correct
AV sync verser 1080p material with a small offset. You can make your home
theaters stand out from the competition by correcting this with the CMX3838A2!
Where does audio video delay mismatch come
from? In todays digitally processed video environment there are many
TV signal processing: Your digital
TVs all have delay, and this keeps growing. The TV speakers will
normally be delay matched for this, but your in wall sound will not be!
Signal distribution: While component
video has no detectable delay, digital transmission does. Each method
Source material: The editing methods
used to create the digital source material do not always use proper methods
to align the video and audio streams. This is very common.
Source equipment: Cable and satillite
boxes often have firmware or design issues that create static mismatches.
We can show you how to use CMX3838A2 to correct
all of these and provide the perfect video and audio environment.
Audio volume control
The CMX3838A2 integrates fully independent input and output volume
adjustments on all audio channels using the best quality digital signal
processing. Why is this important?
The input volume control allows you to equalize the volume
from all sources to a common level. Many satellite boxes output volume
levels below nominal, so without this feature you would need to adjust the
volume manually every time you switch between Cable/DVD to satellite.
After equalization, all your sources will have the same volume level.
The output volume control is mainly used for two types of
applications. The first is to control the volume on your TV speakers from
the centralized system. It eliminates the need to use the TV remote to
control volume. The second application is for in wall/ceiling speakers.
Since volume control is built into the CMX, you can use inexpensive and high
quality fixed gain multichannel power amplifiers to drive your speakers.
Not only does this simplify control, but it will save you several hundred
dollars on the total solution. Please contact sales for details on
recommended fixed gain amps.
The remote control interface can use ZeroKey
infrared code cloning to map any remote control key to each of the inputs &
outputs. ZeroKey technology is compatible with virtually all remote
controls, and does not interfere with the normal operation of the remote.
Please see our quick start guide
for a description of how to program for an IR remote using ZeroKey.
ZeroKey programming is stored in flash memory, and you will
not need to reprogram even if you lose power. If you buy a new remote in
the future, don't worry, the CMX3838A2 can be reprogrammed as much as you like.
CMX3838A2 supports firmware updates over the RS-232 port.
Future updates will add enhanced control and processing features. Follow this
