POSSIBLE REASON:
• This is normal operation for your amp.
CONDITION: Distorted sound.
POSSIBLE REASON:
• Input signal level is too high. Turn down
your amplifier level controls. NOTE: Your
amplifier should never be operated at a
level which causes the Signal/IOC LEDs
to constantly indicate an IOC condition.

appropriate measures to keep the ampli-
fier out of ODEP limiting (see Section
5.1.1 for more information about ODEP).
