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).
