unit model numbers
Mounting:
»Rack mount: Secure the rack ears to each side of the KD-MXA8X8Pro with the supplied
hardware.Then, fasten the unit to the rack rails with the included machine screws.
Unit Configurations:
The KD-MXA8X8Pro is a full matrix audio switcher capable of switching 8 inputs to 8 outputs. Any
input, or source, is available to any output, or zone, at any time. The switcher can also be used as a
distribution amplifier when all outputs are fed from the same source input.
The unit will handle line level Analog audio signals and PCM digital audio signals. It will also
convert Analog signals to Digital, and Digital signals to Analog. Full control of audio properties such
as Bass, Treble, Mid-range, Balance and Lip-Sync are also available. Control of the KD-MXA8X8Pro
is via front panel push buttons, IR remote, serial IR or RS-232.
The KD-MXA8X8PRO can be configured to work in 5 separate Modes.
2
These modes can only be set through the RS-232 command ‘SPO xx T y’.
(see RS232 commands detailed on page 12)
NOTE: The default configuration type is 1.
Type 1 = Left & Right Analog Inputs to Left & Right Analog Outputs with Audio Control plus PCM
Inputs to PCM Outputs in pass through (switching only). Any Audio type can be passed through
PCM in this mode.
Type 2 = Left & Right Analog Inputs to Left & Right Analog Outputs switching with Audio Control
plus Composite Video Inputs to Composite Video Outputs (switching only).
Type 3 = Left & Right Analog Inputs to Both Left & Right Analog Outputs and PCM Outputs. All
have switching and Audio Control.
Type 4 = PCM Inputs to Both Left & Right Analog Outputs and PCM Outputs. Both signals will
switch, only Analog Outputs will have Audio Control. PCM Outputs will be in pass through mode.
Any Audio type can be passed through PCM in this mode.
Type 5 = PCM Inputs to Both Left & Right Analog Outputs and PCM Outputs with full audio
control. PCM Audio will be converted to Analog and processed for control. Will not pass
multichannel audio; Dolby Digital, DTS etc. in this mode.

Quick Setup Guide:
Connections
1. Begin with the KD-MXA8X8Pro and all Input/Output devices turned off
and power cables removed
2. Connect analog audio sources via the left and right RCA inputs, or
digital sources via the PCM inputs
3. Connect the analog audio destinations via the left and right RCA outputs, or
digital destinations via the PCM outputs
4. Connect Video and Audio displays devices.
5. Connect power to the KD-MXA8X8Pro as well as all other input and output devices and turn
them on
6. Operate KD-MXA8X8Pro switcher via the front panel buttons, IR remote, serial IR or
RS-232 control
Operation:
After performing the setup above, the unit is ready for operation. Most applications will just involve
switching for day-to-day operation. There are several options for controlling the unit. Commands
can be issued via IR remote control, RS-232 or by using the front panel buttons.
Matrix Switching via Push Buttons
»For switching inputs, simply press the selection buttons within the desired Output number.
Pressing this button repeatedly will cycle through all Video/Audio Inputs.
Matrix Switching via IR
»To switch Analog Audio: Select the desired Output number, followed by the ‘Audio Mode’
button, then the desired Input number.
»Example. To switch Output 2 to Input 4 press; ’R1-02-Audio Mode-04’
Matrix Switching via RS-232
½To switch PCM (or CV Video) Independently:
»SPOxxSIyy
»xx = Desired Video Output #
»yy = Desired Video Input #
½To switch Analog Audio Independently:
»SPOxxSAyy
»xx = Desired Audio Output #
»yy = Desired Audio Input #
½To switch PCM (or CV Video) and Analog Audio simultaneously:
»SPOxxSyy
»xx = Desired Video & Audio Output #
»yy = Desired Video & Audio Input #

Factory Default Reset:
To perform a factory default reset; with the unit powered on, press and hold Outputs 1 and 8 on the
front panel for 10sec., then release. This will reset the unit to its initial configuration. All customized
settings will be lost.
