  • Supports 32 44.1 48 and 96 kHz sampling rates for broad compatibility
  • Handles 24-bit S/PDIF bitstream on left and right channels for clear audio
  • Provides electromagnetic-noise-free transmission for clean signal quality
  • Simple to install and operate with standard RCA jacks for two-channel PCM input

What this converter does

The Monoprice 6884 converts coaxial or optical Toslink digital stereo audio signals into analog left and right RCA outputs. It handles 24-bit S/PDIF streams at sampling rates of 32, 44.1, 48 and 96 kHz. The unit is intended for home or professional audio switching where a digital source must feed analog amplification.

Check your source and destination

Verify that your source device outputs two-channel PCM stereo only; multichannel formats such as Dolby Digital or DTS are not supported. Confirm the source provides either a coaxial RCA digital output or an optical Toslink port. Ensure the receiving amplifier or powered speakers accept analog stereo input via RCA jacks.

Power and cabling needs

The converter requires an external power supply to operate; plan for a nearby mains socket. You will need one digital cable — coaxial or optical — from the source and one stereo RCA cable to the amplifier. Electromagnetic-noise-free transmission means no special shielding is required beyond standard cables. It does not pass video signals or multichannel audio.

Questions about this item

Does the box include the coaxial and Toslink cables I need to connect my sources, or only the converter?

The package contains the converter unit and a power supply; coaxial and optical cables are sold separately.

The specs list 32, 44.1, 48 and 96 kHz — which one should I pick for a standard TV or game console?

Most TVs and consoles output 48 kHz PCM stereo, so leave the converter on its default setting; it will accept any of the listed rates automatically.

The headline says 24-bit S/PDIF — does that mean I get 24-bit quality on the RCA outputs?

The converter accepts a 24-bit S/PDIF stream and outputs analog stereo at the same bit depth, so you preserve the full resolution through the RCA jacks.
