Digital Audio Converter with Bluetooth 5.0

The LUOM unit accepts optical Toslink, USB flash drives and Bluetooth 5.0 sources, converting them to stereo analogue signals through RCA and 3.5 mm outputs. It is aimed at listeners who want to connect modern digital sources to a traditional amplifier or powered speakers without replacing the existing analogue chain.

Passive desktop operation

The converter draws power from the included USB charge cable and power adapter, so it adds no fan noise or measurable heat to a living-room setup. Headphone amplification delivers 125 mW per channel into 32 ohms, suitable for impedances between 16 and 300 ohms, keeping listening levels clean at typical desktop volumes.

Plug into any analogue input

RCA left and right sockets feed a stereo amplifier, soundbar or receiver, while the 3.5 mm jack serves headphones or a portable speaker. Optical inputs handle PCM and LPCM at 32, 44.1, 48, 96 and 192 kHz, and the USB port plays MP3, WAV, APE, FLAC and WMA files directly from a flash drive. Buyers needing multichannel decoding or HDMI audio extraction will not find those functions here.

Questions about this item

How do I connect the LUOM converter to my TV and speakers, and which step is often missed?

Connect the TV's optical output to the Toslink input, then run RCA cables or a 3.5 mm lead to the amplifier; the step often missed is selecting PCM or LPCM output in the TV audio menu so the converter receives a compatible signal.

What ongoing maintenance or part replacement should I expect with this DAC?

No user-serviceable parts are inside; the only items that may need replacement over time are the external power adapter or USB charge cable if they become damaged.

At what sample-rate ceiling does the optical input stop accepting higher-resolution streams?

The optical input accepts PCM and LPCM up to 192 kHz; any source sending a higher sample rate will not be decoded by this converter.
