Feature
●STUDIO GRADE PORTABLE DIGITAL ANALOG CONVERTOR WITH MQA: BOLT delivers studio sound on the go from any mobile device across all listening formats. Supports MQA (Master Quality Authenticated) streaming for unparalleled fidelity in portable audio. Compatible with Android, iOS, Mac, and PC’s. May require extra adapters or third party apps for MQA support.
●HIGHEST FIDELITY SOUND: MQA (Master Quality Authenticated) rendering “unfolds” every detail of the original master recording as the artist and engineers intended it to be heard for better-than-CD audio resolutions. Stream MQA content from TIDAL, nugs.net, and Xiami. MQA Certified.
●SMARTPHONE, TABLET, MAC & PC COMPATIBLE: USB-C input to a 3.5mm Headphone Output supporting playback of PCM files with sampling rates up to 384 kHz, or DSD files with sampling frequencies up to 5.6MHz. The 3.5mm audio jack seamlessly connects to your wired headphones or speaker system. Note: An adapter is required if you do not have a 3.5mm input jack.
●AMPLIFIED AUDIO OUTPUT & HEADPHONE OUTPUT LEVEL MATCHING: Provides an average increase of +6 dB in devices with combined USB-audio output (where a dedicated headphone audio output isn’t available). Headphone output level automatically detects headphone impedance and sets level accordingly (1V for 150 ohms).
●THX CERTIFIED AUDIO OUTPUT: Exclusively designed for ultra-low harmonic, crosstalk & crossover distortion. Unlike other mobile MQA-DAC designs, the HELM BOLT physically isolates the DAC from the USB connector for improved EMI isolation, and uses a three oscillator design for superior frequency lock with dramatic improvements over single oscillator DAC designs.
●Android 12 Devices: Some Android 12 devices may experience low volume levels using the BOLT. The fix is to upgrade to new firmware found on the HELM Audio Support Page
