Montarbo Palcoplus PLM6800 Powered Controller
PLM6800 combines all of the functions of the LM24 digital controller with a 4-channel, class D amplifier that can deliver up to 1700 W @ 4 ohms per channel.
This state-of-the-art power amp features a switching-mode power supply with power factor correction, which can operate on mains voltages from 85 to 270 V ac (50/60 Hz). There are three separate power supply units – one for the DSP controller section, one for each pair of output sections – and a full suite of protection circuitry to safeguard the amp as well as the connected enclosures. The full-switching operation of the amplifier section provides for exceptional efficiency.
The same state-of-the-art internal processor of the LM24 drives the amplifier section and provides all loudspeaker management functions: crossover, delay, limiting, and EQ. The PLM6800 incorporates all of the presets for the different configurations of the system.
In addition to processing and amplification, PLM6800 incorporates an “intelligent wiring” system, which provides input and output routing and connector switching (both line in/out and power) according to the operating configuration selected in the processor. The PLM6800 power amplifier section features six Speakon® output connectors (two 8-pole and four 4-pole), allowing for rapid cabling of RA16 satellites and RAB1815 subs, and also permitting the connection of four full-range or one-way cabinets to the four, 4-pole Speakon® outputs. This multiple output wiring, which would otherwise seem risky to the satellites if erroneously wired, is made quite safe by the DSP section, which uses internal relays to connect only the correct contacts of the connectors appropriate to the selected preset, disconnecting the unnecessary and otherwise potentially dangerous connections.
This same, “intelligent wiring” concept is applied to the four signal output connectors. These outputs can be set by the user as links or as processed outputs, thereby facilitating the wiring of multiple systems, and systems combining the PLM6800 with LM24s and/or traditional, unprocessed amplifiers.
PLM6800 features an aluminum and stainless steel, etched panel and road-ready construction. Two RJ45 connectors provide RS485FD serial interfaces for network control using the RAConTM software.
