Martin Audio Limited","The MA-NET1 NomadLink®\/Ethernet Bridge acts as a subnet master for up to 60 units (240 channels) of networked NomadLink®-ready amplifiers. Bridging between the NomadLink® daisy-chained network and standard Ethernet\/LAN, the MA-NET1 provides utilization of any standard Ethernet architecture when connecting a PC running the MA Netcontrol software.
Lab.gruppen Powered Loudspeaker Management couples the world's most powerful four-channel amplifier platform to the industry-leading digital sound manipulation features of Lake Processing.","The PLM 20000Q provides four discrete output channels, each rated at greater than 5000 W into 2.2 - 3.3 ohms (4400 W into 4 ohms). To achieve this massive output power, Lab.gruppen engineers designed an all-new universal (100 to 265 V) Regulated Switch Mode Power Supply (R.SMPS) with power factor correction to reduce peak current draw. New output devices in the refined Class TD output stage allow 194 V peak voltage to the load. And the Power Average Limiter works in tandem with a software-controlled Breaker Emulation Limiter (BEL®) to avoid tripping of mains breakers, even with prolonged peak demands.
