1.0 Matrix System Overview
1.0.1 Introduction
ZIGEN AX-88 Audio Matrix Switcher is high performance switcher designed for
applications where routing of audio signals are required. AX-88 Matrix switch is capable
of switching balanced or unbalanced mono or stereo audio signals. AX-88 also ensures
simultaneous distribution of any input source signal to one or more receivers / amplifiers
in (one-to-one / one-to-many combination)
AX-88 matrix switchers are ideal for use in bars, restaurants, hotels, commercial,
medical, military, government, and residential environments where distribution of high
quality, audio signals are needed and audio output volume, treble, bass, lip-sync and
muting is essential.
One of the key features of the AX-88 is the ability to integrate with a fire alarm / life safety
systems. When integrated with fire alarm / life safety, AX-88 will detect and enter in all
mute standby modes until fire alarm / life safety system is reset. This is a great feature
when used in hotels, banquet halls and etc.
In addition, AX-88 comes with independent line-level sub-woofer outputs for each zone
offering the ability to control sub levels independently.
AX-88 also offers you the ability to save 8 frequently used I/O configurations as presets.
AX-88 can be operated via the front panel, RS-232 / RS-485, IR and Ethernet control.

Example: Now there is an AX-88 matrix having all the input/output ports properly
connected to the equipments. If you want to set channel 1 input to channel 2, 3 and 4
output; channel 3 inputs to channel 1 output. There are 2 ways to implement the
switching. Please follow the ways and steps to finish the switching functions:
First way: Directly click on the corresponding icons on the matrix
them into
to transform
to complete the switching operation.
Second way:
Step 1: First select the “Output” number keys 002, then select 003 and final select
004 to the right of the blue configuration area, and select the “Input”
number key 001 to the bottom. Then, press consecutively the previously
selected “Output” number keys 002, 003 and 004. This way, you have
selected “Input” 001 and “Output” 002, 003 and 004 switching.
Step 2: First select the “Output” number key 001 to the right of the blue
configuration area, and select the “Input” number key 003 to the bottom.
Then, press the previously selected “Output” number key 001. This way,
you have selected Input 03 and Output 001 switching.
Upon completion of the above steps, you have actually completed the switching
operation of having channel 1 input to channel 2, 3 and 4 outputs while at the same time
successfully switched from channel 3 inputs to channel 1 output.
The main configuration screen also shows you some function buttons for easy operation:
Switch Tab: Click “Switch” tab to show the main configuration screen.
Audio Tab: Click the “Audio” tab to show the audio related configuration screen. For
more information, refer to 7.0.2.3 Audio Configuration Function.
Video Tab: Click the “Video” tab to show the video related configuration screen. This
function is NOT supported for AX-88.
Disconnect: To disable the connections. After you had configured the connection
between input and output ports, you can click this button to disable the connections.
Select all output: Click this button to select all output ports including output 001~008.

9.0 Troubleshooting
1. What to do if LCD fails to display?
Answer: Check the connection of power cord. Make sure the power cord is plugged and
does not have any damage. Check to make sure the power source is normal.
2. What to do if the audio matrix front panel keys do not respond?
Answer: The Audio matrix front panel keys employ scanning testing and require longer
response time. Press and hold the keys for 2 seconds and then release.
3. What to do if the serial port (usually refer to the computer serial port) fails to control the
audio matrix?
Answer: Check that the communication port set by the control software is correctly
connected to the corresponding serial port of the equipment. Also, check if the
computer communication port is in good order. Check ID address and DIP
Switcher are configured correctly. Refer to 6.0.5.6 Device ID Settings and
6.0.5.5 DIP Switcher 2 Pins.
4. What to do if the corresponding audio signal fails to output during audio matrix
switching?
Answer:
(1) Be sure there is signal on the input end. If there is no input signal, it could be that the
input connection cable is broken or the connector got loose. You are advised to
replace the connection cable.
(2) Check if there is signal on the output end. If there is no output signal, it could be that
the cable is broken or the connector gets loose. You are advised to replace the
connection cable.
(3) Check if the output port number is the same as the controlled port number.
(4) Check the connections of input and output ports are correct.
(5) It could be internal failure of the product itself. You must send for repair by qualified
technical engineers.
5. What to do if you sense the power leakage during plugging or unplugging of the
input/output ports?
47
Matrix Switching System—User Manual
Answer: It could be that the equipment power is not properly grounded. You must
properly ground your equipment; otherwise product life can easily be
shortened.
6. What to do if the audio matrix panel keys and communication ports are out of order?
Answer: Check the power and the computer communication ports are in good order. If
yes, it could be internal failure of the product, please send for repair by
qualified technical engineer.
7. What to do if operation and function failure occurred?
Answer: Check if the equipment and the matrix system are properly connected. If the
problem persists, send the product to the maintenance center for repair.
8. How to avoid the equipment failure due to the high temperature?
Answer: Place the equipment in a well ventilated location.
9. What to do if IR function failure occurred?
Answer: Check the remote control battery and be sure the IR connector is not loose.
Check whether the remote controller is aiming at the IR receiver accurately.
10. What to do if fire alarm function failure occurred?
Answer: Check and be sure the connection is not loose. Check whether the signal is
present, refer to 6.0.5.7 Fire Alarm.

Delay
Audio delay time is 16-bit data. (Unit: 5 ms or 10 ms)
Delay1 - The audio delay time low byte. (Bit0 – Bit7)
Delay2 - The audio delay time high byte. (Bit8 – Bit15)
The audio delay time unit decided by the DTUF flag of the extend information.
The maximum Delay decided by the DTMAX flag of the extended information.

CRC Byte
Example: switch output 6 to the input 3.
Byte 1 (DB) is 0x20 – Device: Identifier + Device ID = 0x20 + 0 = 0x20
Byte 2 (RB) is 0x01 – Request: Switch Video Output Channel = 0x01
Byte 3 (IB) is 0x06 – Index: Output 6 = 6
Byte 4 (VB) is 0x03 – Value: Input 3 = 3
Byte 5 (CB) is 0x93 – CRC code from Byte 1 to Byte 4.
CRC Calculation
CRC 0 = 0 (initial value)
CRC 1 = CRC_ TABLE [CRC 0 ^ Byte 1] = CRC_ TABLE [0x00 ^ 0x20] = 0x23
CRC 2 = CRC_ TABLE [CRC 1 ^ Byte 2] = CRC_ TABLE [0x23 ^ 0x01] = 0x9F
CRC 3 = CRC_ TABLE [CRC 2 ^ Byte 3] = CRC_ TABLE [0x9F ^ 0x06] = 0x8D
CRC 4 = CRC_ TABLE [CRC 3 ^ Byte 4] = CRC_ TABLE [0x8D ^ 0x03] = 0x93
Byte 5 = CRC 4 = 0x93
