Professional Multi-Channel USB Audio Interface Platform

Core Capabilities

The PRO-INTERFACE-K1 platform delivers up to 20-in/20-out USB audio capabilities at 192kHz, far exceeding XMOS solutions (typically limited to 10-in/10-out). The K1 evaluation board demonstrates a 10-in/2-out configuration with a built-in multi-channel mixer, meeting the needs for exhibition demos and rapid evaluation.

Professional Studio

Captures pristine audio with +128dB ADC dynamic range. Four XLR/TRS combo inputs feature independent 48V phantom power per channel, supporting condenser microphones and DI instruments. 192kHz high sample rate ensures professional-grade recording quality.

Key Features

Flagship ESS Codec Chain

Dual ES9823QPRO ADC (+128dB DR) and quad ES9039Q2M DAC (+130dB DR) work in synergy. The entire chain is paired with 15 OPA1612 precision op-amps. Professional audio performance is verified by chip datasheets.

Multi-Channel USB Audio Capability

The platform supports 20-in/20-out USB audio at 192kHz@32bit, breaking through the bandwidth limitations of traditional XMOS solutions. The K1 evaluation board is configured as 10-in/2-out to fully demonstrate the platform architecture advantages.
