The PreMax is an all-in-one channel strip that combines a low noise mic preamplifier with a state-of-the-art 3 band equalizer to deliver exceptionally clean results each and every time it is used.

The design begins with a high performance Op-Amp coupled with Radial's unique Accustate gain control that simultaneously sets the input sensitivity and signal gain to deliver outstanding signal-to-noise at all levels. Visual monitoring is provided with LEDs for signal and overload. The preamp then feeds a traditional 3 band EQ for tone shaping. This musical sounding EQ lets you gently boost the top end for more clarity, add warmth to the bottom end, or cut back the mids on an overly aggressive instrument. A front panel switch lets you bypass the EQ and compare the pre-post effect. This is augmented with a high-pass filter to eliminate low-end resonance that can cause a track to sound muddy or lack detail. A 180° polarity reverse works double duty to either help align a stereo mic setup or enable the PreMax to be interfaced with older vintage gear that may not follow the AES Pin-2 hot convention. For safety, the 48V phantom power switch is recessed to prevent accidental turn-on which could damage tweeters or vintage ribbon microphones. When used with a Radial Workhorse power rack, the Omniport jack is configured as an instrument input and activated using a convenient front panel switch. When the Omniport is not connected, the switch acts like a microphone mute.

Designed to deliver quick, dependable results, the PreMax's integrated design eliminates the concern of matching levels between modules. You simply plug in, set the gain, tone shape and start recording. This makes the PreMax the perfect channel strip module for project studios, post production, broadcast and live recording.


  • Using the PreMax with a microphone - Nothing can be easier than recording with a PreMax. Yousimply plug your mic into the XLR input on your 500 series power rack, turn onthe phantom power and the PreMax does the rest for you! All you do is adjustthe level, set the EQ and press record.
  • Using the PreMax with an instrument - Overdubbing or tracking instruments is quick andefficient. Connect your bass to the Omniport input on the rear of your Radialpower rack, and when you are ready, toggle the input from mic to instrumentusing the front panel switch.
  • Using the PreMax for broadcast - The PreMax is your easysolution for broadcast and voice-over in post production. It combines a lownoise front end with a great sounding EQ for quick results where time ismoney. No more messing around with levels... just plug in and get the resultsyou need.
