The next generation of Bogen's Platinum Series (PS) Amplifiers delivers the highest audio volume for all speaker types at specified power levels, eliminating the need for an external impedance-matching transformer. The Gen-2 Platinum Series amplifiers include an internal impedance-matching transformer and a rear-panel selector switch with separate connector blocks for both 8-ohm/25V and 70V speakers. These new models also retain the powerful features of the first-generation PS models, including the 5-band full parametric equalizer (EQ).
