The Audient iD44 MKII 20 x 24 USB Audio Interface is an improved version of the original iD44 audio interface. It features better audio performance, more features, and a new smoke-grey finish.

Audio Performance
Improved audio converters with a wider dynamic range (126 dB) for more accurate recordings.
Even lower distortion on the analog-to-digital converters (ADCs) for cleaner audio.

Additional Features
Audio loop-back which allows you to capture audio from your computer along with your microphone recordings. This is useful for content creators, podcasters, and streamers.
Dual headphone output so you can connect two sets of headphones at the same time.
Three programmable function buttons that you can assign to your favorite monitoring features.
ScrollControl which lets you use the volume knob as a virtual scroll wheel to control various settings on your computer.

Key Features

• Four high-quality Audient Console mic preamps for recording microphones.
• Two JFET instrument inputs for guitars, basses, and other instruments.
• Two balanced inserts for connecting outboard effects units.
• ADAT expandability which allows you to add up to 16 additional channels of mic preamps.
• Ultra-low latency mixer for direct monitoring while recording.
• Built-in DSP for adding effects to your recordings.
• All-metal construction for durability.
• Includes a three-year limited warranty.
