Unit Configurations:
The KD-MSVA4X4Pro is a full matrix audio / video switcher capable of switching 4 Inputs to 4
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 audio signals to Digital, and Digital audio 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-MSVA4X4Pro may be through Front Panel push buttons, IR Remote, Serial IR or RS-232.
The KD-MSVA4X4PRO can be configured to work in several Modes. There are 3 Audio Modes
available when in the RGBHV (VGA) mode and 5 Audio Modes available when in Component

The commands are not case sensitive. The command lines are shown with spaces for clarity. No
spaces are required when entering commands.
All standalone units have ‘00’ as their default address. When multiple units are used as in an
expansion configuration, each unit will have a unique address. In this case, all below commands
should start with the Prefix: ‘A zz’ , where zz = [01-99] and represents the units System Address.
This will ensure the commands are sent to the correct unit.
Values for Commands:
Address zz = 00-99 (Default standalone 4x4 is 00)
Inputs xx = 01-99 (or A = All)
Outputs xx = 01-99 (or A = All)
Output Volume yy = 00-96 (Default is 80)
Output Bass yy = 00-24 (Default is 12)
Output Middle yy = 00-24 (Default is 12)
