Description
For engineers who live between the FOH desk and their phone, the FiiO Q1 Mark II gives your iPhone a real digital-to-analog conversion chain instead of relying on the phone’s built-in audio. Built around an XMOS platform, it decodes PCM up to 384kHz/32-bit and native DSD up to DSD256 (with a green LED confirming DSD lock), backed by dual crystal oscillators that each handle a specific range of sampling rates for tighter clock accuracy across formats.
Inside, the conversion work is done by an AKM AK4452 DAC chip, chosen for low distortion and strong signal-to-noise performance even with high-res files. Headphone output runs through the same OPA926 amplifier chip used in FiiO’s flagship X7 Mark II AM3A module, so low-noise headphone drive isn’t reserved for the expensive gear. A Texas Instruments OPA1662 handles low-pass filtering on the line output for a clean, accurate signal path.
The Q1 Mark II connects to your iPhone via the included Lightning-to-micro USB cable, letting you keep using standard 3.5mm headphones while bypassing the phone’s internal audio circuitry entirely. Useful for reviewing FOH recordings, checking rough mixes, or just getting more honest playback from reference tracks between sets — it’s a small addition to a gig bag that makes a real difference in what you’re actually hearing.
