The MV210-HC is a bi-amp 3-way loudspeaker with a passive crossover used on the mid and high frequency bands. It requires 2 channels of amplifier and DSP. With these Lake XP-based pre-sets, the Module Output Mixing (MoM) setup is no longer used, but instead, these pre-sets utilize the 3 band Multiband on each of the Module outputs. The MS121 subwoofer requires 1 channel of amplifier and DSP for normal forward firing operation. Cardioid bass set ups will require additional amplifier and DSP channels. All Manchester series Loudspeakers exclusively use LAKE pre-sets via Lab Gruppen PLM+ and D series L platforms. No other amplifier and DSP platforms are supported. Manchester series has a powerful yet simple pre-set strategy utilizing the latest functionality of LAKE software, along with new acoustic compensation for length of array and throw distances required (explained later in this QSG). Pre-set data is found either via the Lake Load Library or can be downloaded from www.turbosound.com. Recommended Lab Gruppen PLM+ models for Touring applications are the PLM12k44 and PLM20k44. For installations using Lab Gruppen D series L models, please use Lab Gruppen ‘CAFE’ software - available for download from www.labgruppen.com - to determine the optimum amplifier configuration for your system.
