The Zypher Labs DubStepper Series Bass Amplifiers, are dedicated Heavy Duty ‘Bass Only’ Amplifiers, specially designed to deliver huge amounts of power into subwoofers. The high efficiency of Class-D enables continuous duty at full power with negligible heat dissipation.
Conventional Toroidal Transformers allow large current draw on a sustained basis while increasing reliability through simplicity. High damping factor keeps tight control over the speakers, and the voice coil’s back EMF is recycled into the amplifier’s main voltage rails for even greater power output. Full set of protections, along with a 3-stage speaker protection system. ensure reliability during extended hours of opteration under heavy loads
Because high power into low impedance loads requires high current, extra heavy-duty components are used – 100 Ampere Bridge Rectifiers, 80 Ampere Relays, and dual speakon outputs to connect 4 Ω load on each speakon.
DubStepper Z series amplifiers are optimized for 4Ω loads, whereas the DubStepper series is optimized for 2Ω loads.
