The Q1 Mark II utilizes the AKM AK4452 DAC chip to decode high sample rates, giving you a high signal-to-noise ratio and providing low distortion. The headphone amplifier chip in the Q1 Mark II is the very same utilized in the AM3A module, usually used with the X7 MARK II (OPA926). Finally, low-pass filter duties on the line-output are handled by the TI OPA1662 chip
By connecting the included Lightning-to-USB cable from the iPhone to the device, you can continue to use your favorite headphones from your iOS device, all while listening to high-quality audio.
The Q1 Mark II can operate as a USB DAC when paired over USB with a computer. It can decode audio formats up to 384 kHz / 32-bit (PCM). No driver is needed for use with a Mac computer, while Windows will require a driver easily available from FiiO's website.
