ARX is proud to introduce the e-pre - the ultimate microphone pre-amp for hard disk recording, designed by audio professionals, not computer engineers. The all-new e-pre is so much a part of your system that it fits right into a spare 5¼" slot in your computer case! It's the perfect tool for all your day-to-day recording requirements. No equipment racks to plug in, no masses of cabling to connect - the e-pre is ready and waiting when you need it.

The e-pre is a studio quality microphone pre-amp using the same internal components as high end mixing consoles, built into a compact, computer friendly package.
It has controls for:

  • Input Gain - fully variable from 10dB through to 60dB to suit all types of microphones, plus switchable 48 V Phantom Power to enable condenser microphones to deliver their best.
  • A Contour control for EQ sweetening, providing fast, easy access to a whole range of useful EQ curves
  • Output level control - fully variable to match the e-pre's output to the input of the sound card. From -10dB consumer cards through to +4dB for professional sound cards, the e-pre can handle it.

Multiple output connectors match up with any kind of sound card, including mini jacks, standard jack, RCA (phono) plugs, and even a connector to link to the internal CD ROM audio input of your sound card (if fitted).
We've even fitted a 12 VDC input connector on the rear to enable the e-pre to run from an external power supply if required (eg for use with notebook computers or stand-alone use).

Any way you look at it, the e-pre by ARX is the total professional microphone pre-amp for all your hard disk recording needs
