Introduction
About the KD-MSA8X8
The KD-MSA8X8 is a full matrix audio switcher capable of switching 8 inputs to 8 outputs. The idea behind a full matrix switcher is the fact that any input, or source, is available on any output, or zone, at any time. Likewise, the switcher can also be used as a distribution amplifier when all outputs are fed from the same source input.
The unit will line level analog audio signals and PCM digital audio signals. Multi-channel surround signals such as 5.1 are also accommodated by using two inputs and two outputs for every source and zone (see page 4). This yields the capability of switching 4 inputs to 4 outputs. There is no ‘conversion’ process, therefore analog input yields analog output, digital input yields digital output and encoded signals are passed through the unit without decoding.
Control of the KD-MSA8X8 is through front panel push buttons, IR remote, serial IR or RS-232.

3. IR eye and serial IR port
a. IR eye on the rear panel is identical to that on the front of the unit and can be used with a flasher or the supplied IR remote. It offers a convenient way to conceal unsightly IR flashers.
b. The serial IR port can be used with serial IR control systems.
4. Programming switch:
a. This is used to switch between programming mode (for updating the unit’s firmware) and normal operation. See page 11.
5. Power Connection
6. RS-232 Connector:
a. This connector has two functions. It serves as a serial communication port for connection to RS-232 based control systems and also for firmware updates via serial connection to a standard PC. See page 8 for RS-232 control protocol and page 11 for firmware update procedure.

2. LED Input Indicator Bank
a. Indicates selected input port for associated output
3. IR eye
a. The IR eye on the front panel receives commands from IR remote controls or IR flashers. Note that an identical IR eye is also available on the rear panel. When IR control is enabled (factory default, though this can be disabled via RS-232. See page 8), both eyes are concurrently active.
After all audio connections are made on the rear panel of the KD-MSA8X8 as described on page 4, connect the supplied power adapter. Lastly, apply power to all other sources and displays or destinations.

CAUTION: When installing the unit, make all audio connections before plugging
in the external power supply provided with your unit. Do NOT apply power to the unit until all audio connections have been made to your KD-MSA8X8 unit from the “source” devices to the display(s) and/or devices. You MUST use the external power supply provided with your unit or you VOID the Key Digital® Warranty and risk damage to your unit and associated equipment.

Operation
After performing the setup above, the unit is ready for operation. When the unit is initially powered on all LED indicators are off until either:
An RS-232 command is issued
IR power on is issued
Any front panel button is pressed
Most applications will involve only input switching for day-to-day operation. There are a several options for controlling the unit. Commands can be issued via IR remote control, RS-232 or simply by using the front panel buttons. Keep in mind that controlling the unit in a 4 input/4 output multi­channel analog surround setup requires concurrent switching of two inputs and two outputs for each input source and output zone.
Front Panel Control
For switching inputs, simply press the ‘Input Select’ button within the desired output section. See number 1 on Figure 4. Pressing this button repeatedly will cycle through all audio inputs.
IR (Remote Control)
The KD-MSA8X8 ships with an IR remote control providing selection of inputs for every output. As illustrated in the following diagram, these convenient keys are clearly marked.
To issue a command via IR to switch inputs, issue the following sequence:
1. First, press the button labeled ‘R1’
2. Next, press the buttons for the unit’s address [00-99]. Factory default is 00
> When multiple units are used in a system, unique unit addresses allow for error free switching,
ensuring that only the addressed unit ‘listens’ to the command issued. This is especially helpful in IR control situations.
3. Then, press the ‘Output Select’ rocker style button up or down to select the desired output to
switch. Note that the LED’s will flash, indicating selected output.
4. Next, press the ‘Input Select’ rocker style button up or down to select the desired input. Note
that the LED’s will indicate selected input.
5. Finally, press the ‘R1’ button to complete the sequence. Note that the LED indicators will flash
for 30 seconds or until ‘R1’ is pressed. Whenever the LED’s are flashing, the status of that output can be switched and no other output can be changed. To end one sequence and begin another, press ‘R1’ or wait 30 seconds for LED’s to stop flashing.
Alternatively, the output and input selection in steps 3 and 4 above can be made in the following manner.
3. Press the number keypad buttons [01~08] to select the desired output to switch. Note that the
LED’s will flash, indicating selected output.
4. Then, press the number keypad buttons [01~08] to select the desired input. Note that the LED’s
will change, indicating selected input.
For all IR commands, the steps 1 and 2 above must be issued fir st to address the unit. See the following button labels for IR commands.

›
›
IR Extender
You may also want to use an IR extender, such as available by Xantech:
A rear panel sensor is perfect for use with Xantech IR extender
A wired IR serial connector is also provided
You’ll need to either mount the IR extender on the side of the KD-MSA8X8 unit, or connect the serial connector cable.

RS-232 Control
The KD-MSA8X8 provides access to all functions when used with an RS-232 control system.
Connection protocol is as follows:
Baud rate: 57600
Data Bits: 8
Parity: None
Stop Bits: 1
Flow Control: None
Key Digital provides a resource database for downloadable control modules at: www.keydigital.com/controlmain.aspx
The KD-MSA8X8 features AMX’s Device Discovery beacon.
When connected to qualifying AMX control systems via RS-232, the KD-MSA8X8 identifies itself so that the control system automatically loads the appropriate module. This feature makes integrating into AMX RS-232 control systems incredibly simple.
The KD-MSA8X8 RS-232 cable pin out is as follows:
RS-232 codes for the KD-MSA8X8
The commands are not case sensitive. The command lines with spaces shown below are for easy recognition. Spaces are not necessar y when entering these command lines in the control system, though adding them for easy recognition will have no negative effect.

Firmware Update
From time to time, Key Digital may provide firmware updates for the KD-MSA8X8. These updates are optional, and should only be performed as instructed by Key Digital. Below is the procedure for updating the firmware. Please note that incorrect update processes can result in an unusable unit. Follow the detailed directions carefully.
Firmware Update Procedure
Check our web site at www.keydigital.com for the latest firmware update ZIP file. Download and unzip the firmware ZIP file to any directory on the PC. All of the unzipped files that are created must be located in same directory on the PC.
Be sure power to the unit is ‘off’. The power button on the rear panel must be ‘out’ or off to have a complete power shutdown - reset.
With power off, set the rear-panel slide switch (see page X number 12) to “Program” mode. Do not yet apply power to the unit.
Connect an RS-232 cable to the COM1 serial port on the PC, and the other end to the RS­232 port on the rear panel of the KD-MSA8X8 unit. Make sure that no devices are using the COM1 serial port on the PC.
Turn on power to the KD-MSA8X8 unit.
Double-click the ‘KD-MSA8X8.bat’ file from within the ZIP folder. The command mode window should pop up. Monitor this pop-up window to see that the firmware update is going well. This step of the firmware update process should take no longer than 45 seconds.
If an error occurs, check the RS-232 connection and repeat all of the above steps.
When the update is complete, the screen will appear as follows:
Disconnect the RS-232 cable between the unit and the PC.
Turn off power to the unit. The power button on the rear panel must be ‘out’ or off to have a complete power shutdown - reset.
With the power off, set the rear­panel slide switch to “Normal” mode.
Turn on power to the KD-MSA8X8 unit. Push the ‘On” button on the rear panel.
The firmware update is now complete, and the KD-MSA8X8 is ready for operation. In order to confirm the new firmware version, issue the help command ‘h’ via either your control system, HyperTerminal or any similar terminal program. The firmware version is displayed at the top of the response.
