## Description

HELM Audio Bolt DAC/AMP, USB-C Portable High-End DAC/Headphone Amplifier with MQA Playback. Mobile Studio Sound for Android, iOS and PC. USB-C to 3.5mm Audio, THX Certified

## Features

- Serious Sound Quality in the Smallest Package - Plug in and immediately hear the sound quality dramatically improve from any mobile device across all listening formats. Bolt delivers studio sound on the go and supports MQA files for a new level of portable audio. Works with Android, iOS and PC's. May require extra adapters or third party apps for MQA support. *Scan the QR code in the manual for the latest set up videos for each platform. Questions, please reach out to our support team.
- Like 4k Video for Your Ears Master Quality Authenticated (MQA) unlocks every detail of the original master recording with the convenience of streaming audio. MP3 and similar audio streams deliver 10% of the original recording quality, but the HELM BOLT can stream and unfold MQA content to stunning better-than-CD audio resolutions. Stream MQA content from Tidal, nugs.net, and Xiami.
- Plug-In and Hear the difference: 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.
- Amplified Audio Output and Headphone Output Level Matching 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.). Note: Increased dB levels vary based on each type of set up. Email our support team with any questions, we are here to assist.
- Exclusive Design with THX Certification: Ultra-low harmonic, crosstalk, and 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 other DAC designs.
