The ICON ProAudio Duo44 Dyna is a 4-in/4-out recording USB interface designed for both studio and live streaming applications, offering a blend of analog and digital connectivity with smart mobile devices. This device is bus-powered via USB 2.0 High-Speed, ensuring fast and stable signal processing, and is compatible with Mac, PC, iOS, and Android platforms.
Function Description:
The Duo44 Dyna serves as a central hub for audio input and output, allowing users to record and play back audio simultaneously across 4 analog inputs and 4 analog outputs. It features two mic/instrument preamps with individual gain control and phantom power switches, catering to a variety of microphones and instruments. A key feature is its smart device connectivity, offering both digital (Type C OTG) and analog (3.5mm stereo TRRS) I/O jacks for direct connection to smartphones, tablets, or other mobile devices. This enables live streaming applications where audio signals can be processed via the ProDriver4 virtual plug-in rack before being sent to the smart device. The device also includes MIDI I/O connectors for integrating MIDI devices into your setup.
For monitoring, the Duo44 Dyna provides two analog outputs on 1/4" TRS jacks, a monitor volume control knob on the top panel, and a direct monitor button. A dedicated headphone output with assignable source and individual volume control is also included. The "Direct monitor" knob allows for hardware direct monitoring, eliminating latency by listening to inputs and existing tracks directly. Alternatively, users can monitor inputs with effects by selecting "Computer" monitoring, leveraging the low-latency ASIO monitoring.
The device's functionality is significantly enhanced by the ProDriver4 software control panel, which offers flexible channel routing and a plug-in hosting rack. This allows users to integrate their favorite VST, Audio Units, and Direct X plugins for real-time audio signal processing. The ProDriver4 system is engineered for ultra-low latency, providing a robust platform for recording and live performance. It supports a "LoopBack" function for both Mac and Windows, enabling internal audio routing for various applications.
