Welcome 2. Welcome 2.1 Introduction Thank you for choosing the Lab.gruppen PLM Series of Powered Loudspeaker Management systems 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.
Welcome 2.2.2 Amplifier 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.
Welcome Please refer to the Lake Controller Operation Manual for further information regarding the Analyzer plug-in and associated functionality. 2.2.5 Dante™ Audio Network PLM Series devices include Dante digital audio networking as standard. Utilizing the latest advances in Ethernet technology, Dante offers simplified system configuration and extremely low latency while delivering very high quality uncompressed digital audio across the Lake network.
Installation 3. Installation 3.1 Unpacking 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.

Installation 3.3 3.3.1 Cooling Overview 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.
Installation The PLM uses primary switching, which means the mains power is rectified on the primary side of the transformer. This makes the power supply insensitive to mains frequency variation, and it will operate normally on line frequencies from 45 to 75 Hz.
Product Overview 4. Product Overview This chapter provides an overview of key features and functionality. For further information please see chapters 5 to 9 of the PLM Series Operation Manual. 4.1 Front Panel Overview Figure 4-1: Front Panel Overview The front panel controls are clustered around a daylight readable LCD , allowing adjustment and monitoring of the majority parameters and meters.
Product Overview Display The display illuminates when the device is on. The LCD, function buttons, and the rotary encoder provide real-time control and monitoring of most parameters. The LEDs embedded in the function buttons indicate available menu options, provide confirmation of Controller communication, and indicate various faults and warnings. The brightness and contrast of the display and front panel LEDs can be adjusted via the front panel menu.
Product Overview The LED in the top button provides Frame fault and warning indications. The middle two buttons provide Module input mute functionality, mute indication and faults and warning indications relating to the PLM inputs. The bottom button is used only in Menu Mode or to lock the front panel buttons. Please refer to chapter 6 of the PLM Series Operation Manual for further details.
Product Overview 4.2 Back Panel Overview Figure 4-2: Back Panel Layout Options for a 4-channel PLM Figure 4-3: Back Panel Layout Options for a 2-channel PLM PLM Series Quick Start and Field Reference Guide Rev 1.3.
Product Overview 4.2.1 Input and Link Connectors Analog Inputs Analog inputs are available on two standard XLR3F latching connectors. The inputs are electronically balanced and feature Lake Iso-Float circuitry. The impedance is 20 kohms, and the inputs can accept a maximum input level of +26 dBu. Analog Links Two latching XLR3M connectors are fitted adjacent to the analog input connectors.
Product Overview Binding Posts In this version, the power outputs for loudspeaker connection are available on four separate pairs of fully enclosed binding posts. Bridge Mode can be enabled via the Lake Controller software, please refer to the Lake Controller Operation Manual for further information. Channel configuration for the binding posts is dependent on the PLM model, please refer to section of the PLM Operation Manual for standard and Bridge Mode wiring.
Product Overview The Ethernet ports operate at the Ethernet data rate of 100 Mbps, and allow straight or crossed network cables. Two LEDs above each port indicate valid network connection (LINK) and network activity (ACT). Secondary Connector The secondary network connector can be used to daisy-chain multiple LM & PLM Series devices.
Signal Flow and Lake Processing 5. Signal Flow and Lake Processing 5.1 Signal Flow The figures below depict the audio signal flow for a PLM Series device. It is worth noting that this sophisticated device provides seven points in the signal chain where the signal level can be adjusted, muted or disconnected. The blue sections represent Frame data, and the red sections represent Module data - please refer to the Lake Controller Operation Manual for further information.
Signal Flow and Lake Processing Output Router Stage - Output on/off routing connections Attenuation Stage - Power output channel mute and attenuation settings Amp Gain Stage - Amplifier gain control If the required audio signal is not passing correctly, verify the connection, mute and gain settings at all seven stages. 5.1.
Signal Flow and Lake Processing The sophisticated output section monitors faults and generates warnings when appropriate; warnings are displayed on the front panel of the PLM and also sent as messages over the control network. In the rare event that maximum ratings are significantly exceeded, the PLM will mute until the condition has been rectified or the incorrect setting has been readjusted.
Signal Flow and Lake Processing 5.3 5.3.1 Modules and Frames Overview A Frame represents one physical Lake Processor (e.g. PLM 10000Q). A maximum of two Modules are contained within each Frame; these are referred to as Module A and Module B. The number of Modules shown in a given Frame is dependent upon the signal processing configuration of that Frame.
Signal Flow and Lake Processing 5.4 Loudspeaker Processor Overview The Lake Processing system within PLM Series devices may be configured with up to two processing Modules containing a total of up to six processing Module outputs, although the number of power outputs will be either two or four depending on the PLM model being used. To make use of the extra processing channels, multiple hardware devices may be connected together using the Super Module feature as summarized in section 5.3.3.
Signal Flow and Lake Processing A maximum of 100 Frame Presets can be stored on this device. The data within a Frame Preset includes the configurations of all Modules in the Frame, including levels, crossover, EQ, input mixer, routing, and all other parameters. As Frame Presets are stored in the hardware device, recall is available without using a PC.
Quick Start Tutorial 6. Quick Start Tutorial 6.1 Introduction This section describes installation of the Lake Controller software, input and output connections, basic functionality, and setup instructions. The information provides a basic level of understanding of the system architecture along with configuration instructions for a basic system application.
