Switchable 48 V DC Phantom Power for condenser Mics
Compact, computer friendly package
Needs no external power supply
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
5?" 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

Key Features
ISA Series Transformer-based Pre-amplifier
Encased in a rugged and portable chassis, ISA One offers the classic Focusrite microphone pre-amplifier at its lowest cost to date.
Flexible Independent D.I. Channel
ISA One is ideal for both engineers and demanding performers alike, featuring independent gain control, an output for routing to an amp, an independent XLR output on the rear and routing to the optional ADC.
Switchable Impedance
Choose one of four carefully selected input impedances, including the original ISA 110 setting, to suit any microphone.
Optional Stereo 192kHz ADC
This optional card embodies cutting-edge conversion technology, incorporating Focusrite analogue circuitry to deliver the best A-D performance in its class (Dynamic range of 119dB).
Rugged Custom Flight Case
Built to protect your ISA One from the rigors of the road. Rugged plywood construction with a solid polypropylene exterior and reinforced corners.

Meters
| Moving Coil (MC) Meter |
factory calibrated to 0VU = +4dBu with 1kHz sinewave. With the VU Cal button pressed the meter can be adjusted on the rear panel to allow 0VU to equal +10dBu to +26dBu with the centre detent being equal to +22dBu. |
| Peak LED Meters |
Calibrated in the detent position for 0dBFS = +22dBu, calibration is adjustable on the rear panel to allow 0dBFS to equal +10dBu to +26dBu |
| Routing for MC and Peak1 meter is after the HPF, pre insert send or switched post insert return. Peak2 is always pre ADC channel 2, which can be fed by external input or Instrument input. |
