2.2.2Amplifier DSP (Digital Signal Processor)
Various features of PLM Series devices are controlled by the on-board DSP, some of which are summarized in this section.
2.2.2.1 Input Gain (Sensitivity)
Input gain (sensitivity) is set in the digital domain for PLM Series devices, and may be controlled via the Lake Controller software or front-panel interface.
2.2.2.2 ISVPL™
The Inter-Sample Voltage Peak Limiter (ISVPL) tailors each power output to the characteristics of the connected load. Please refer to section 5.3.1 of the PLM Operation Manual for further information.
2.2.2.3 Load Verification & Performance Monitoring
A comprehensive set of proprietary DSP-based tools are provided for load verification and real-time performance monitoring. These functions utilize LoadLibrary, a comprehensive database for each loudspeaker component of the connected load (usually one or more band-limited drivers in a multi-way system).
Using this data and a brief test signal, LoadSmart compares actual response to predicted response, identifying any malfunctioning components or connection errors. During the performance, SpeakerSafe™ monitors real-time load status, including temperatures of the PLM amplifier stages as well as magnets and voice coils of connected loudspeakers. This allows operators to avoid power compression and identify potential problems.
Please refer to the Lake Controller Operation Manual for detailed information on PLM Series load verification and real-time performance monitoring functionality.
2.2.3Lake Processing and Controller
PLM Series devices integrate seamlessly into the Lake Processing environment and are accessible via the Lake Controller software. Processing modules offer precise settings for gain, delay, crossover settings, equalization and limiting. Lake processing features incorporated in each module include Raised Cosine Equalization™, linear phase crossovers, and LimiterMax™ loudspeaker protection. The Super Module feature allows hardware processing modules in two or more separate devices to function as a single module in the Lake Controller software. Please refer to the Lake Controller Operation Manual for further information.
2.2.4Analyzer Plug-In
Lake Controller software provides integration with third-party real-time analyzers, providing simultaneous measurement display and EQ adjustment via the Lake Controller.

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. Save the carton and packing materials for the carrier’s inspection.
In addition to the PLM Series device, the shipping carton include the following items:
PLM Series Quick Start & Field Reference Guide
AC mains lead (power cable) with Neutrik® powerCON® connector
Rear brackets for additional rack support (pair) along with associated mounting hardware
Software Installer and Documentation CD-ROM or USB key
Please keep the original carton and associated packaging to facilitate shipping of the device should the need arise.
3.2Mounting
Airflow for cooling the device is from front panel (intake) to rear panel (exit). Please ensure that no object, such as rack doors or lids are placed at the front or rear of the rack to ensure that airflow is maximized. This device has no top or bottom vents and therefore may be stacked directly on top of each other.
Sufficient space should be available at the front of the rack to accommodate the handles, and at the rear to accommodate connectors and cables; allowance must be made for cable or loom bends within a rack.
3.2.1Rear Mounting
Two rear support brackets along with associated mounting hardware are included with the PLM, as shown in Figure 3-1; it is recommended that these are used wherever possible. Fit the brackets to the vertical rails at the rear of the rack. Figure 3-2 and Figure 3-3 show the fitting options for fixed and removable installation.
The support brackets are reversible and may be fitted to point either to the front or rear of the rack; the orientation used depends on the rack depth and position of the rear rack rails.
Two mounting methods are possible; note that the method shown in Figure 3-2 additionally provides extra security against unauthorized removal. For situations where rapid removal and replacement is required, the method shown in Figure 3-3 should be used.

3.3Cooling
3.3.1Overview
The PLM Series devices use a forced-air cooling system with airflow from front to rear, allowing high continuous power levels without thermal problems. Front-to-rear airflow is preferable as air at the front of a rack is cooler than that at the rear in nearly all situations; never attempt to reverse the airflow. The operation of the PLM’s cooling system is dependent on front-to-rear airflow; it will not function effectively with external airflow in the opposite direction.
Make sure an adequate air supply is provided in front of the PLM, and that the rear of the PLM has sufficient space to allow air to escape. If the PLM is rack-mounted, never operate the unit with any front or rear rack doors or covers in position. It is recommended to keep the ambient temperature around the PLM as cool as possible. An increased temperature can have a significant negative impact on the expected lifetime on the components inside the PLM.
Fit solid blanks (not ventilation blanks) to unused rack spaces to ensure effective air circulation. Leaving gaps in between items of equipment degrades the effectiveness of forced-air cooling.
If installing one or more PLM Series devices in a rack with other fan-cooled equipment, be sure that all the other equipment also uses front-to-rear airflow for cooling. If this precaution is not observed, there is a risk of overheating, as units with the reverse airflow will be drawing in air which has already been heated by the PLMs.
3.3.2Temperature Sensing and Protection
The PLM is equipped with a sophisticated temperature sensing system which protects it from any overheating which may occur as a result of inadequate ventilation.
Always ensure the dust filters behind the detachable front panel are clean to ensure maximum possible airflow.
3.4Operating Voltage
The label adjacent to the mains (AC) input connector indicates the AC mains voltage for which the device is wired and approved. The PLM 10000Q and PLM 14000 devices are available in separate 115 V and 230 V versions; the PLM 20000Q is only available with a universal power supply operating from 80 to 265 V. Only connect the mains cable (AC cord) to an AC source of the voltage shown on the label.
