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 51/4" 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,

Applications

Console input extending for both Digital and Analog mixing consoles in Studio, Live and Broadcast
Mic Pre-amps for DAW/ Hard Disk/ Multitrack Recording

Innovation
If you love your compact Digital (or Analog) mixing console, but wish it had more microphone inputs, ARX has the solution – the 8-Pre: eight channels of superb sounding Microphone Pre-amps in a compact 1 rack space chassis.

The 8-Pre is the ideal console extender for those times when you need more microphone inputs. Now you can put those unused line inputs to good use, and who knows - the 8-Pre pre-amps sound so good that you’ll probably end up using them all the time instead of the ones that came with your mixer!

Superb Audio Quality
The 8-Pre’s ultra low noise figures come from extensive use of premium components plus care and attention to board design and layout. The result is superb, transparent audio quality and the headroom to handle anything that a microphone can throw at it.

Gain is adjustable from 20 db through to 60 dB via a trim control on the front panel, plus we’ve included a –20dB Pad switch to tame the hottest condenser microphone output if required. The Clip status LED lights up 1 dB before the onset of clipping, just to warn you you’re getting close. Phantom power is switchable in banks of four channels: 1 through 4, 5 through 8. A Phase reverse switch is also provided on each pre-amp channel to eliminate any close miking problems.

In short, the ARX 8 Pre is the microphone Pre-amp that you’ll wish the console manufacturer had used. It provides a unique solution to today’s multiple Mic Pre-amp requirements.

ARX Quality
Every day, ARX Audio interface products solve audio problems for thousands of people around the world. We don’t make digital or analog mixers and we don’t have to cut any corners on quality.

Yes, we know we’re obsessive about audio quality, but we’re betting that you are, too!
