PowerPre Specifications

The PowerPre has been optimized for sonic character while still delivering exceptional specifications. With 55dB of pure gain, yet measuring less than -122dBu of noise and greater than 97dB of dynamic handling, the PowerPre is more than capable of handling just about any microphone or source. During listening tests, the sound proves to be remarkably smooth yet astonishingly quiet. This is attributed to attention detail with respect to grounding and part placement along with use of the discrete electronics and the Hammond output transformer. The Vox control adds yet another dimension by introducing two carefully sculpted curves that will enhance and flatter most microphones.
