Dr. Voice is a great feature of AX4B Max / AX4B U2, which can identify the problems you
may encounter in the operating system. It can clearly "tell you" whether the problem is
caused from components or improper installation such as CPU, memory module, VGA, PCI
add-on card, FDD, HDD or keyboard. Dr. Voice provides four language versions: English,
German, Japanese and Chinese. You can select your preferred language by JP15 & JP16
jumpers. However, if you want to disable this function, you may also adjust both JP1 and
JP2 and set them to pin 2-3 to disable the buzzer and speaker from making out voices.

13. S/PDIF Connector
S/PDIF (Sony/Philips Digital Interface) is a latest audio transfer file format that provides
impressive quality through optical fiber and allows you to enjoy digital audio instead of analog.
Normally there are two S/PDIF outputs as shown, one for RCA connector, the most common
one used for consumer audio products, and the other for optical connector with a even better
audio quality. Through a specific audio cable, you can connect the SPDIF connector to a
S/PDIF audio module bearing S/PDIF digital output. However, you must have a S/PDIF
supported speaker with SPDIF digital input to make the most of this function.

14. JP1 Buzzer and JP2 Speaker Jumpers
This motherboard comes with another considerate option that allows you to turn off the voice
from buzzer and speaker. You can choose not to be bothered by the warning made from Dr.
Voice when it detects any error in operating system. To disable this function, set JP1 and JP2 to
pin 2-3 to stop both buzzer and speaker from sending out voices.
