The perfect audio interface for musicians on the move
Designed as the ideal Audio/MIDI companion to notebook computer-based recording environments, the iO|2 USB has a compact form factor that can easily fit in a laptop case or small backpack. The iO|2 USB features durable aluminum casing, USB power (eliminating cumbersome external power supplies) and is optimized for minimal laptop battery drain.
The iO|2 provides 2-channels of pristine 24-bit/48kHz audio directly to your computer via the integrated USB interface and features 2 channels of switchable mic/line inputs. And with Hardware Direct Monitoring, you never have to worry about dealing with audio latency while recording.
Small enough to fit in a backpack, but powerful enough to get the job done right, the iO|2 is perfect for musicians on the go.

FREQUENCY RESPONSE:
- MIC/LINE IN to SPDIF/USB OUT: +/-0.1dB Input Gain = minimum
- MIC/LINE IN to MAIN OUT (through ADC/DAC) +/-0.35dB Input Gain=minimum
SIGNAL-TO-NOISE RATIO (SNR):
- MIC/LINE IN (balanced) to INSERT OUT: 110dB A-weighted, input impedance at XLR or 1/4" jack = 600 Ohms, Input Gain = minimum
- GUITAR IN (unbalanced) to INSERT OUT: 99dB A-weighted, input impedance at 1/4" jack = 600 Ohms, Input Gain = minimum
- MIC/LINE IN (balanced) to SPDIF/USB OUT: 99dB A-weighted, input impedance at MIC or LINE jack = 600 Ohms, Input Gain = minimum
- GUITAR IN (unbalanced) to SPDIF/USB OUT: 94dB A-weighted, input impedance at 1/4" jack = 600 Ohms, Input Gain = minimum
- MIC/LINE IN (balanced) to MAIN OUT (through ADC/DAC): 97dB A-weighted, input impedance at MIC or LINE jack = 600 Ohms, Input Gain = minimum
- MIC/LINE IN (balanced) to MAIN OUT (through direct monitor): 95dB A-weighted, input impedance at MIC or LINE jack = 600 Ohms, Input Gain = minimum
TOTAL HARMONIC DISTORTION + NOISE (THD+N):
- MIC/LINE IN (balanced) to INSERT OUT: <0.001% Input Gain = minimum, 1KHz input signal, INSERT OUT = 5.7dBV
- GUITAR IN (unbalanced) to INSERT OUT: 0.034% Input Gain = minimum, 1KHz input signal, INSERT OUT = 5.3dBV
- MIC/LINE IN (balanced) to SPDIF/USB OUT: 0.003% Input Gain = minimum, 1KHz input signal, DIGITAL OUT = -0.3dBFS
- GUITAR IN (unbalanced) to SPDIF/USB OUT: 0.034% Input Gain = minimum, 1KHz input signal, DIGITAL OUT = -0.7dBFS
- MIC/LINE IN (balanced) to MAIN OUT (through ADC/DAC): 0.005% Input Gain = minimum, 1KHz input signal, MAIN OUT = 5.6dBV
- MIC/LINE IN (balanced) to MAIN OUT (through direct monitor): 0.006% Input Gain = minimum, 1KHz input signal, MAIN OUT = 5.6dBV
