    Carefully open the shipping carton and check for any damage to the device or the supplied accessories. Every Lab.gruppen product is tested and inspected before leaving the factory and should arrive in perfect condition. If any damage is discovered, please notify the shipping company immediately. Only the consignee may initiate a claim with the carrier or their insurers for damage incurred during shipping.

  • Page 8: Mounting

    7. Installation 7.2. Mounting PLM+ is made for mounting in 19 inch racks. Four screw holes are available for attachment of the amplifier to the racks front rack rail. This device has no top or bottom vents; therefore, units may be stacked directly on top of one another.

  • Page 9: Cooling And Fan Operation

    8. Cooling and fan operation 8. Cooling and fan operation PLM+ devices use a forced-air cooling system with airflow from front to rear, allowing high continuous power levels without thermal problems. To facilitate maximum air flow, ensure that no objects such as rack doors or lids are placed at the front or rear of the rack.

  • Page 10: Low Voltage Country Considerations

    9. Operating voltage 9.1. Low voltage country considerations Although the PLM+ Series has a wide range of operating mains voltage, some considerations can be applicable for low voltage regions. PLM+ performs well throughout the specified nominal voltage range but has slightly better efficiency at higher voltages.

  • Page 11: Grounding

    10. Grounding 10. Grounding Use correctly-shielded balanced audio input connections to minimize hum and interference. PLM+ Series must be grounded (earthed) with the safety ground pin to the mains distribution system. NEVER disconnect the earth (ground) pin on the mains cable (AC power cord). 11.

  • Page 21: Rational Power Management

    13.4. Rational Power Management™ Rational Power Management™ (RPM) is a unique Lab.gruppen feature that allows for flexible allocation of power across channels of a PLM+. Power that is not used by one output channel is free for use by another output channel with greater demands.
  • Page 22 13. Quick Start Tutorial Auto RPM: The frame will automatically allocate power per output channel according to the ISVPL settings in the Lake module. If the ISVPL settings taken together allow total output higher than the capabilities of the amplifier, RPM will reduce the ISVPL limiter thresholds evenly based on a proportional reduction in dB.
