## Summary description

The InLine AmpUSB-EQ is a high-resolution USB audio DAC that supports DSD audio formats. It features a Micro-USB port for connectivity and offers headphone outputs of 3.5 mm and 6.35 mm.

## Long description

The InLine AmpUSB-EQ 384KHz/32bit DSD USB Audio DAC is a compact hi‑res digital-to-analog converter and headphone amplifier that connects a computer or mobile device to a music system via USB. It converts PCM audio up to 384 kHz/32 bit and supports native DSD playback (up to DSD128) or DoP, providing a cleaner digital interface than typical onboard sound cards. The unit includes multiple inputs (micro-USB, RCA/phono, optical SPDIF, line-in/aux) and outputs (3.5 mm and 6.3 mm headphone jacks, SPDIF/pre-out and bass out), and offers an integrated analog-to-digital record function to digitize external sources such as turntables or cassette players.
Advantages
The device uses a high-quality ES9018Q2C DAC chipset combined with a 12AU7 tube stage and a dedicated headphone amplifier to deliver transparent audio reproduction across a wide range of headphone impedances (16–600 Ω). It supports asynchronous USB transmission, ASIO drivers and is compatible with Windows and macOS; optional adapters allow connection to Apple and Android devices. The AmpUSB-EQ provides tri-band tone control, a hardware loudness EQ, MM/MC turntable selector and de-pop circuitry to reduce startup/shutdown noise. LED indicators show PCM/DSD playback and input status, while the metal housing increases durability.
