PreMax™ Specifications

The Radial PreMax is a 500 series module that combines a state-of-the-art preamp with a carefully sculpted EQ. By combining the two into a single channel strip, gain levels are easier to manage for more professional results. When tested, the PreMax preamp section delivers a linear response with greater than 112dB of usable dynamic headroom that is capable of handling input signals in excess of +20dB. The filter and EQ curves are equally as impressive with smooth, musical sounding renderings. This results in an impressive sounding module that will deliver great sound quickly and consistently no matter what the situation.
