Figure 5.3a : Use washer for fixed installation Figure 5.3b : Use tube for slide-on installation INsTAllATON 5 5.4 Cooling the PLM uses 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.
5 INsTAllATON 5.5 Operating Voltage the label adjacent to the mains (aC) input con- nector indicates the aC mains voltage for which your PLM is wired and approved. the PLM Series is available in two versions: 115 V and 230 V. Connect the mains cable (aC cord) only to an aC source of the voltage shown on the label.
6.1 Introduction this section covers installation of the Dolby Lake Controller (DLC) PLM Edition software, input and output connections, basic functionality, and setup instructions. the information will allow a user to achieve a basic level of understanding of the PLM Series system architecture while also setting up the unit for a basic system application.

4.2 for download links. 6.3.2 Software and firmware Updates Both Lab.gruppen and Dolby Lake strive to improve and update the capabilities of PLM Series products. Many of these improvements are available to PLM Series users as free updates of the Dolby Lake Controller PLM Edition software application and PLM Series firmware.
6.4 how to Configure the pLM the following tutorial presents a “walk-through” of the steps involved in a typical loudspeaker system configuration. it will allow the user to become familiar with the basic structure and operation of the PLM Series implementation of Dolby Lake processing. this tutorial employs the Dolby Lake Controller (DLC) PLM Edition software, though some steps are accessible via the PLM’s front panel.

LF, MF, HF and sub channels. alternatively, a Lab.gruppen LoadLibrary file would have been used that would already contain the necessary data to configure gain, crossover and limiter settings.
6 QUICK sTArT TUTOrIAl 6.5 Gain Settings the architecture of the PLM Series provides gain adjustments at a number of points in the signal flow path. thus, there are many places in which one can adjust the levels in the PLM. Each point serves a different purpose.
PLM. this control replaces the traditional knob found on conventional amplifiers. it should typically be left at 0 dB during use. (adjust in Lab.gruppen info, Status tab) Amp Gain Corresponds to the gain that you would have available in a conventional system if the amplifier section was outside the PLM.
7 CONTrOls AND CONNECTIONs 7.1 front panel the PLM’s front panel is based around a 2.5” daylight- readable backlit liquid crystal display (LCD), through which control and monitoring of most functions are performed via a simple menu system. Controls are grouped in two switch clusters alongside the display;...
