The PreMax is a combination low-noise mic preamp and 3 band equalizer jam packed into a single-wide 500 series module.

The PreMax is a combination low-noise mic preamp and 3 band equalizer jam packed into a single-wide 500 series module. The 'all-in-one' channel strip will be of particular interest to those who require greater density in their production studios or on-air radio broadcast inputs. The feature set includes Radial's super quiet Accustate input control that auto-pads the input while optimizing signal-to-noise. A high pass filter eliminates resonance while a 180° polarity reverse lets you match stereo mics for phase parity. A front panel instrument input lets you turn on the Omniport (which in this case is optimized as an instrument input) for direct recording of bass, guitar or keyboards.

 

The PreMax begins with a low-noise Op-Amp input coupled with Radial's unique Accustate gain control that simultaneously sets the input sensitivity and signal gain to deliver ultra-quiet performance at all levels. Visual monitoring is supported with LEDS for signal and overload. The preamp then feeds a traditional 3 band shelving EQ for tone shaping. A front panel switch enables the user to bypass the EQ to compare the pre-post effect.  This is augmented with a high-pass filter to eliminate low-end resonance that can cause a recorded track to sound muddy. A 180°polarity reverse works double duty to either help align stereo mic placement or to help tame acoustic hot spots when using the PreMax in a live stage setting.  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 the front panel switch. When not connected, the switch acts like a microphone mute.

 

As with all Radial products, construction is second to none. The PreMax's thick front panel is supported with a 16 gauge L-frame and the circuit is encased in galvalume to minimize noise caused by outside electromagnetic fields. Switches are also encased in steel and the sealed potentiometers employ steel shafts for extra durability. Connection to the frame features double sided gold contacts for optimal signal flow.
