GETTING STARTED
Think of the HDR 24/96 as a standard PC with extra Mackie boards inside. Standard
PC troubleshooting techniques and commercially available diagnostic DOS software
can be applied to repair the HDR 24/96.
A preliminary inspection will often reveal a simple problem, such as a bad
connection somewhere, perhaps a loose cable, a bad switch or control, bad EEPROM or
the CPU's CMOS settings may need to be reset. Check out the service bulletins, there is
one which explains how to replace the EEPROM.
Our technical support team are available to discuss any problems and offer solutions.
