Microphone Preamps

Use a class-A microphone design developed by legend David Dearden and optimised over 18 years of refinement
Clean, punchy and musical character
Flexible topology – design optimised gain range between 0 – 70 dB gain
Low Noise Floor:  30,000 times quieter than the signal level
Wide Bandwidth: Preserving your transient detail
Transformer-less, RF-immune input stage for detailed resolution

ConvertorsiD4 provides you with high-performance AD-DA convertors. Quality in the analogue stages of design comes from years of experience as analogue console designers, and when coupled with outstanding convertor technology it enables you to hear audio as it’s supposed to sound
ScrollControlWith 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 PlayiD4 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
Monitor PaniD4’s Monitor Pan feature enables you to pan both the mic pre input and D.I input from left to right, making it easy for you to create a balanced headphone mix that suits you
Monitor MixiD4’s Monitor Mix feature lets you monitor a blend of both iD4’s inputs and your DAW playback, providing near-zero-latency monitoring while recording. Designed with creativity in mind, Monitor Mix allows you to quickly blend in your DAW playback and start recording along to your multitrack instantly, enabling you to focus on the music and lay down your track effortlessly
Dual Headphone OutputsFeaturing 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 headphone adapter
Built to LastiD4 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
