Analog to Digital Audio Converter, RCA L/R & 3.5mm Jack AUX to Coaxial/Optical Toslink SPDIF Audio Adapter, 48kHz/24bit PCM LPCM Stereo ADC, for TV/CD/Game Console/Soundbar/Headphone

Description

Product Overview

The Closs Analog to Digital Converter is engineered to bridge the gap between legacy analog audio sources and modern digital playback systems. By accepting RCA left/right or 3.5mm AUX inputs, the unit transforms the incoming signal into a pristine PCM/LPCM stream that can be routed through either coaxial SPDIF or optical Toslink outputs. The converter supports a sampling rate of 48kHz and a bit depth of 24‑bit, ensuring that music, movies, and game audio retain their original fidelity. Housed in a robust metal enclosure, the device resists electromagnetic interference and provides a stable platform for long‑term use. No external power bricks are required; a micro‑USB cable supplies the necessary power, simplifying installation in any entertainment setup.

Usage

Designed for a wide range of consumer electronics, this converter fits seamlessly into home theater systems, gaming rigs, and portable audio stations. Connect the RCA or 3.5mm output of a DVD player, vintage gaming console, or CD player to the input ports, then link the coaxial or optical output to a soundbar, AV receiver, or powered speakers that accept digital audio. Because the unit does not include a built‑in volume control, users can fine‑tune the level at the source device, preserving the integrity of the digital signal. The plug‑and‑play nature means you can set up the converter in under a minute—simply plug the cables, power the unit, and enjoy crystal‑clear sound without the need for drivers or software.

FAQ

Can I use this converter with a Bluetooth speaker?

No. The device is designed for wired connections only. It converts analog signals to digital formats that can be sent to receivers, soundbars, or speakers with coaxial or optical inputs.

Do I need to install any software?

No. The converter works as a pure hardware solution. Simply connect the appropriate cables, power the unit via the supplied micro‑USB cable, and it will start converting immediately.

What sample rates does the converter support?

The unit supports a fixed 48kHz sampling rate with 24‑bit depth, which is the standard for most consumer audio equipment and provides high‑resolution sound.

Is there a way to control volume through the converter?

The converter itself does not include a volume control. Adjust the volume on your source device (TV, CD player, game console) or on the downstream digital receiver to achieve the desired listening level.

Will this work with a modern TV that only has HDMI ARC?

If your TV only offers HDMI ARC, you will need an HDMI‑to‑SPDIF adapter or a separate audio extractor to feed the analog signal into the converter. The converter accepts only RCA or 3.5mm analog inputs.
