  • Tech Specs

    CMA400i has a great capability for signal processing, supporting Windows XP, Vista, 7, 8 & 10, and Mac OS.

    When connecting to a computer, it is only responsible for sending data. So everything related to sound quality will be guaranteed by CMA400i, no matter if it is a song, a film or a game.

    The performance of a traditional Hi-Fi system can be much improved by CMA400i because of its completely separate DAC with optical and coaxial interfaces. Another distinctive feature of CMA400i is switching between "Headphone Amplifier" and "Pre-amplifier" by the "Function" switch on the front panel. In DAC mode, CMA400i supports RCA and XLR pre-amp outputs which can be selected by the ADJ/FIX switch on the rear panel.

    The CMA400i follows the design of Questyle Audio CMA600i DAC-headphone amplifier. The headphone amplification of CMA400i achieves low distortion of 0.00064% and ultra wide bandwidth up to DC-600kHz(+0,-3dB), working under super-current and Class A state only, all of which allows CMA400i have excellent performance at headphone amplification among the DAC/amp models. CMA400i’s USB input supports True DSD. Different from the commonly used DoP mode, CMA400i processes source data directly from PC and its hardware will switch to the True DSD channel when the system processes DSD signals, strictly following the process of SACD playback.

    CMA400i supports pre-amp unbalanced (RCA) and balanced (XLR) outputs. RCA pre-amp output level is up to 4Vrms, and XLR up to 8Vrms, which can meet the requirements of most power amplifiers for output level. Volume control works in analog mode only. It is user-friendly for users of high-end active speakers. CMA400i supports 4PIN balanced output. Four groups of pure Class A current mode amplification circuits drive headphones in full balanced mode, doubling the output voltage, quadrupling the output power against that of single-ended mode. It can easily drive headphones with high impedance and low sensitivity rating and is able to reveal the full performance of your headphones.

    1) Support USB, SPDIF, and Optical digital inputs.
    2) USB port supports 44.1k-384k/16-32Bit PCM files, as well as Native DSD64, DSD128, DSD256, and DoP64, DoP128 decoding.
