5. Introduction 5. Introduction 5.1. Welcome Thank you for choosing the Lab.gruppen PLM+ Series for your sound reinforcement needs. We are confident that you will be pleased with the performance, unique features, configuration flexibility, reliability, and long-term durability offered by this product. For fast installation and use of this product, your welcome package includes this printed copy of the PLM+ Series Quick Start Guide.
. Installation 6.2.
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. Sufficient space should be available at the rear to accommodate connectors and cables. In addition, allowance must be made for cable or loom bends within a rack. 7.2.1.
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. Never attempt to reverse the airflow.
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. For regions with nominal voltage below 140 V, one could consider connecting the amplifier in a three-phase delta or two phase split-phase configuration.
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. Product overview 11.1. Front panel Additional information on operations using front panel controls is available in the full PLM+ Series Operation Manual.
11. Product overview Mute Enable – Selection of MUTE ENABLE allows dynamic function buttons to operate as Mute controls for the module inputs and power output channels. The MUTE ENABLE button flashes when the mode is selected; a subsequent press deselects the mode. If left activated, MUTE ENABLE mode will automatically disable two minutes after last mute action. 5 Meter – Successive presses of the METER button scroll through meter views: Amp, Temperature, Input and Module meters, returning to Home.

11. Product overview Use the primary connector when using a star network topology, consisting of individual Cat-5e connections between the devices and an Ethernet switch. Alternatively, this connection can be used to daisy chain directly to another Lake Processor. The daisy chain topology should not be used with Dante. For a technical reference of the Ethernet Port, please refer to the full PLM+ Series Operation Manual. Additional information is also available in the Lake Network Configuration Guide.
12. Signal flow and processing 12. Signal flow and processing The table below depicts the audio signal flow for a PLM+ device.
13. Quick Start Tutorial 13. Quick Start Tutorial This section will describe how to get started with associated software and set up a basic system for operation. 13.1. Network setup 13.1.1. Network connections / topology Each frame has two network ports; a primary and a secondary. See the below diagram for a typical network topology using the primary ports. By default, the secondary ports are configured in dual redundancy mode to support a second redundant network.
13. Quick Start Tutorial 13.2. Software installation and firmware update 13.2.1. Lake Controller software suite 1. The Lake controller software suite includes the Lake controller and accompanying utilities: Lake LoadLibrary and Dante discovery services. Download the Lake Controller installation from www.labgruppen.com. 2. Execute the installer and follow the on-screen instructions. This is a typical software installation where the default settings are acceptable for the vast majority of users. 13.2.2.
13. Quick Start Tutorial 13.3. System setup This tutorial provides a step-by-step guide for configuration of a typical professional loudspeaker system and provides an overview of the basic features and operation of the frame. It describes how to configure 4-channel frame for use with a generic 3-way loudspeaker system (with separate HF, MF and LF drivers), plus a separate subwoofer.
13. Quick Start Tutorial Bridge Bridge 1 2 3 4 14. The B module is already a CL1way as default and can be used to drive the sub. 15. Tap Store/Recall EXIT to return to the Modules Menu. 16. Ensuring Module A (or any other module that you want to control) is selected (yellow border), tap I/O Config. 17. The right side of the I/O CONFIG screen displays a block diagram for the Modules.
13. Quick Start Tutorial Levels Control - Drag sliders and tap mute buttons for module input and output channels. Parametric EQ control – Select filter on the top squares and adjust filter properties by dragging the controls. Sliders at the bottom control center frequency and Q (bandwidth). Gain is controlled in the main window area. Additional filters can be added by tapping the top filter objects and placing new filters on the main area.
13. Quick Start Tutorial 21. Repeat step 16 and 20 for the B module. On the Output EQ/Crossover, tap the Aux Output Functions button on the menu bar and then tap LPF Enable button. Drag the Low pass filter control object on the frequency slider just above the menu bar to an appropriate crossover frequency for the sub, e.g. 100 Hz. Output EQ control - Add LPF/HPF and EQ filters and drag to adjust. 22. Use the control options mentioned in 17 to tune your loudspeakers.
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. When RPM is active, an RPM icon will be displayed next to the “Actual ISVPL” values in the Events & Control section.
14. Faults and warnings 14.
14. Faults and warnings Category/Type Name On screen text Description Action Increase mains distribution stiffness or reduce output power to avoid limiting PSU Warning Under Voltage Limit UVL ACTIVE The Under Voltage limiter is active as the mains supply is approaching the lower end of the device´s operational voltage.
