Errors Requiring Boulder Dealer Service
If the 1160 Stereo Power Amplier will not turn on and the front panel LED
blinks red, an error requiring dealer service has occurred. The indicator
may ash red in a specic sequence to dene its error code for an
authorized Boulder technician.
If you are experiencing this problem with your 1160, contact your Boulder
dealer immediately.
Operational Errors
At times the 1160’s front panel LED may ash red but continue operating
normally. This is an Operational Error and indicates that there is a fault
somewhere else in the system or in the use of the amplier. Conditions that
will be indicated as Operational Errors may include:
• DC offset at the input of the amplier (from a source or preamplier)
• Thermal limit or safe operating temperature of the amplier exceeded
• Clipping of the output signal
