Fault Protection

The Nº53 is designed to prevent damage to itself and associated components. These extensive features protect both the critical circuitry of the amplifier itself and shield connected loudspeakers from serious damage due to critical high-power levels.

Basic protections designed into the Nº53 include fuses on the AC input line for each transformer to protect against excessive current conditions, such as driving shorted outputs. Inrush limiting prevents premature aging of the power supply components during power-up; once the power supply has been charged, this feature goes off-line until the amplifier is powered up again.

The Nº53 power amplifier also incorporates a controlled clipping circuit. This circuit reduces the harsh high-frequency harmonics typically generated when an amplifier goes into clipping.

 

ML Net Fault Conditions

 

The slave devices in an ML Net system can report fault conditions to

28

the master device. Fault condition reports are displayed on the

display of the master device when the fault occurs.

When a fault condition occurs, the Nº53 mutes the amplifier output and the main power supply is shut down. The Nº53 remains in fault mode until the fault condition is resolved and the amplifier is power-cycled (turn off the rear panel Power switch, wait at least 10 seconds, then turn the Power switch on). If the fault cannot be resolved, contact your authorized Mark Levinson dealer or contact Mark Levinson customer service.

The fault conditions reported are:

• Slave Device DC Offset – indicates that the Nº53 amplifier is experiencing a signal-related fault.

• Slave Device Over Current – indicates that the Nº53 is experiencing an over-current condition.

• Slave Device Over Temperature – indicates that the Nº53 amplifier is overheating.

• Signal – indicates that the Nº53 has experienced a general signal fault.
