Nº532 Power Amplifier

Fault Protection

The Nº532 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 Nº532 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 Nº532 power amplifier also incorporates a controlled clipping circuitry to prevent output devices from saturating. The harsh high-frequency harmonics typically generated by hard-clipped output devices are avoided by the controlled clipping circuitry.

ML Net Fault Conditions

The slave devices in an ML Net system can report fault conditions to the master device. Fault condition reports are displayed on the display of the master device when the fault occurs. Some faults may cause the Nº532 to enter Standby or Power Save mode. Power-cycling the Nº532 clears the fault condition, providing the fault condition no longer exists.

Note Some faults do not allow power to be reapplied to the amplifier until the fault condition no longer exists to protect the amplifier from damage.

The fault conditions reported are:

•Slave Device DC Offset – indicates that the Nº532 amplifier is experiencing a signal-related fault.

•Slave Device Over Current – indicates that the Nº532 is experiencing an over-current condition.

•Slave Device Over Temperature – indicates that the Nº532 amplifier is overheating.

•Signal – indicates that the Nº532 has experienced a general signal fault.
