4. Key Features

The Audient iD24 incorporates several features designed to enhance your audio production workflow and quality.

4.1. Audient Console Mic Preamps

The iD24 features two Class-A Audient Console Mic Preamps, utilizing the same discrete circuit design found in Audient's ASP8024-HE recording console. These preamps are engineered for ultra-low noise and low distortion, providing a clean, accurate, and warm signal path for your microphones.

4.2. Class-Leading AD/DA Converters

Equipped with 32-bit DAC converter technology and 126dB of dynamic range, the iD24's converters ensure that every subtle detail of your audio is captured and reproduced with remarkable clarity, aiding in precise mixing decisions.

4.3. JFET Instrument Input

The dedicated JFET instrument input is designed to replicate the input stage of a classic valve amplifier, providing a harmonically rich sonic foundation for direct guitar or bass recording before any amplifier simulations.

4.4. Balanced Inserts

The iD24 includes two fully balanced inserts, allowing seamless integration of external hardware effects (e.g., compressors, EQs) into your signal chain before analog-to-digital conversion. The insert returns also provide direct access to the A/D converters for the cleanest possible signal path.

4.6. Assignable Monitor Control

The three programmable F-buttons (F1, F2, F3) on the iD24 allow for quick access to advanced monitoring features such as Speaker Select, Talkback, Polarity Invert, or Mono Sum, streamlining your workflow.

4.7. Compact, Portable & Bus Powered

Constructed with an all-metal, smoke-grey chassis and hand-milled aluminum knobs, the iD24 is built for durability. Its bus-powered design makes it highly portable and suitable for both desktop studio use and on-the-go recording.
