Audient Class A Console-Grade Microphone Preamp: Equipped with the same discrete Class A microphone preamp circuitry as Audient's flagship ASP8024-HE recording console, delivering ultra-low noise (-128dB EIN), low distortion, and a warm, transparent classic British analog sound.
Industry-Leading AD/DA Converters: New converter technology provides an impressive 120dB Dynamic Range (ADC) and 125.5dB Dynamic Range (DAC), ensuring your recordings capture every subtle dynamic and that you hear the most authentic sound details during monitoring.
Audiophile-Grade JFET DI Instrument Input: Plug in your guitar or bass directly to get rich harmonics and full tone derived from classic tube amplifiers. This JFET DI input adds just the right amount of color and punch to your instrument's sound.
Dual Headphone Outputs: Simultaneously offers both 1/4-inch and 3.5mm headphone outputs, allowing connection of various monitoring headphones without any adapters. The powerful headphone amplifier circuit can easily drive high-impedance headphones, ensuring a clear and robust monitoring experience.
ScrollControl™ Virtual Scroll Wheel: With a single press, the iD4 MKII's volume knob transforms into a virtual scroll wheel, allowing you to precisely control faders, plugin parameters in your DAW, or even computer system volume, significantly boosting workflow efficiency.
Zero-Latency Monitor Mix Control: The Monitor Mix knob allows you to freely blend playback audio from your computer (DAW) with direct input signals, achieving latency-free recording monitoring, enabling performers to more accurately control their performance.
Robust All-Metal Chassis: Features an all-aluminum casing and handcrafted aluminum knobs, offering not only a professional appearance but also an extremely sturdy and durable structure, capable of withstanding various demanding environments.
USB 3.0 Bus Powered: Connects via a USB-C port and is fully powered by the computer's USB bus, eliminating the need for an external power supply for true plug-and-play functionality, ideal for mobile creation.

Audient Class A Console-Grade Microphone Preamp

Inheriting Classic Analog Sound: Directly adopts Audient's globally renowned recording console design, providing professional studio-grade sound quality.
Ultra-Low Noise Performance: Features extremely low Self-noise (EIN: -128dBu), ensuring pristine recording backgrounds even at high gain, perfectly capturing the subtle dynamics of vocals and acoustic instruments.
Warm and Transparent Tone: Combines the warm characteristics of analog circuitry with the transparency of modern design, adding pleasing musicality to the sound without excessive coloration, preserving the authenticity of the original source.

Audiophile-Grade JFET DI Instrument Input

Recreating Classic Amp Tones: The JFET (Junction Field-Effect Transistor) circuit design aims to simulate the input stage of classic tube amplifiers, bringing rich second-order harmonics and warm saturation to electric guitars or basses.
High-Impedance Input: Ensures the instrument's original signal is captured completely and without loss, preventing high-frequency attenuation and maintaining tonal clarity and dynamics.
Plug-and-Play Convenience: No need for an additional DI box; simply connect your instrument directly to the iD4 MKII's front panel input to start recording professional-grade instrument tracks.

Industry-Leading AD/DA Converters

Astonishing Dynamic Range: Up to 120dB Analog-to-Digital Conversion (ADC) Dynamic Range allows your recordings to capture every detail, from the faintest breath to the loudest passages, without omission.
Accurate Monitoring Playback: Up to 125.5dB Digital-to-Analog Conversion (DAC) Dynamic Range ensures that the sound you hear is extremely close to the original recording, helping you make more precise mixing decisions.
Less Noise and Distortion: Superior converter performance means lower Total Harmonic Distortion plus Noise (THD+N), keeping your audio path pure for cleaner, more impactful sound.

Innovative ScrollControl™ Virtual Scroll Wheel

Enhancing Workflow Efficiency: Brings the intuitive feel of a physical knob to your digital workstation, replacing mouse dragging with rotation for faster, more musical operation.
Broad Compatibility: Compatible with all major DAW software and plugins; any parameter controllable by your mouse scroll wheel can be controlled by ScrollControl.
