Meyer Sound’s SIM 1 & SIM 2 were stepping stones that brought us out of the stone age & into modern sound system design & optimization. SIM stands for “Source Independent Measurement”. The current version is SIM 3. All SIM platforms are based around a stand alone hardware / software system. The following is taken directly from Meyer Sound’s own website.
