Product information

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.

Listening to high-resolution PCM and DSD audio from a PC or laptop

Digitizing analog media (vinyl records, tapes) via the record function

How to use

Select the desired input with the input select button (USB, SPDIF, RCA, line-in). Connect headphones to the 3.5 mm or 6.3 mm jack and adjust volume and tone controls (treble/mid/bass) to achieve the preferred sound. To digitize analog sources, connect the playback device to the RCA/phono or line input, enable the record function and save files on the connected PC or laptop.

Usage recommendations

Use the DC24V/2A power adapter supplied with the unit and install the appropriate drivers for Windows or macOS to ensure correct ASIO and DSD playback. For mobile devices, use official camera kit or OTG adapters as needed. To avoid pops during power cycles, allow the unit to complete its startup or shutdown sequences and use the de-pop feature.
