designed to protect both the amplifi er and your loudspeakers against dangerous
fault conditions. Signifi cantly, these protection circuits do not intrude upon
or limit the normal performance of the amplifi er; rather, they simply put the
amplifi er into protection mode when confronted with abnormal conditions.
Th ese conditions include:
• output overload
• DC off set
• AC mains voltage (outside of normal tolerances)
• excessive operating temperatures
If any such conditions occur (any of which might harm either your amplifi er or
possibly your loudspeakers), the amplifi er will immediately go into protection
mode. In such a case, a Channel LED indicator will blink red until the fault can
be righted and the amplifi er is re-started.
If the fault is not channel-related, e.g. AC mains voltage out of range, the
Standby LED will blink. In all cases, the unit will need to be re-started once the
cause of the fault condition has been rectifi ed.
