unit model numbers

Mounting:

»Rack mount: Secure the rack ears to each side of the KD-MSA8X8Pro with the supplied

hardware.Then, fasten the unit to the rack rails with the included machine screws.

Unit Conﬁgurations:

The KD-MSA8X8Pro 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-MSA8X8Pro

is via front panel push buttons, IR remote, serial IR or RS-232.

Page 4

The KD-MSA8x8PRO can be conﬁgured to work in 5 separate Modes.

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-MSA8X8Pro 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-MSA8X8Pro as well as all other input and output devices and turn

them on

6. Operate KD-MSA8X8Pro 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.
