We are the only company that uses the same Class-A mic pre design throughout our entire product range, whether you’re in the studio with an Audient console or on the road with iD4, you’re always guaranteed the same world class Audient sound.

Mic Pre Technology

We take an insight into why our microphone preamplifier design has become so popular amongst so many professionals and hobbyists alike.

The Audient Mic Pre Guarantee

We are the only company that uses the same Class-A mic pre design throughout our entire product range, whether you’re in the studio with an Audient console or on the road with iD4, you’re always guaranteed the same renowned Audient sound.

Evolution of the Audient Mic Pre

Designed by David Dearden (of DDA & Advision Studios) back in 1997 the Audient mic pre is an all discrete high grade op amp design that delivers low noise, low distortion, and high common mode rejection at all gain levels…offering a faithful reproduction of the source with just enough colour to give the signal some character.

The Design Rationale

The microphone preamplifier has historically been the most difficult circuit block to design and also the block where designers have striven to express their individuality. David Dearden has always been on a quest for musical transparency and below he outlines his design.

Pristine Converter Technology

iD4 provides you with high-performance AD-DA converters. Quality in the analogue stages of design comes from years of experience as analogue console designers, and when coupled with outstanding converter technology it enables you to hear audio as it’s supposed to sound. The importance of converters should never be underestimated. Experience audio the Audient way.

Converter Technology

High-quality AD/DA converters are a vital factor in hearing what you’re recording or mixing accurately. We have chosen some of the best converters available to make sure all our products offer you stunning translation.

Scroll Control

With a touch of a button iD4’s volume encoder becomes a virtual scroll wheel, enabling you to adjust DAW hosts, plug-in parameters and even scroll through your iTunes library – just like you’re adjusting a piece of hardware. Wherever your mouse pointer hovers, the iD knob can scroll to control! And when you’re not using ScrollControl, pressing iD4’s volume encoder activates DIM, enabling you to quickly reduce the playback volume.

Plug and Play

iD4 has a harmonically rich JFET D.I input. Designed to replicate the input stage of a classic valve amplifier, you can plug your guitar, bass, keyboard or drum machine straight in and start recording instantly. Get professional quality recordings from the start and take your track to the next level.

Dual Headphone Outputs

Featuring a dual headphone output, iD4 enables you to collaborate with your friends and other artists. Whether you’re recording a guitar and a vocal, or just listening to music together, iD4 lets you plug in two sets of headphones, making it the perfect tool for jamming with your friends and capturing creativity as it happens. The dual headphone output also has both a jack and mini jack output, so no more need to carry around a pesky headphone adaptor.

iOS Compatible

iD4 supports iOS compatibility which means recording on the go is easier than ever. Watch the video to see just how easy it is to set up iD4 with an iOS device. All you need is a Camera Adapter Kit and a Powered USB Hub and you’re ready to start recording anywhere.

Built to Last

iD4 has been designed to last, from its all-metal construction, hand finished aluminium knobs and high grade component selection, iD4 will stand up to countless late nights in the studio and days on the road.
