The Best Optical Audio Jack Buyer’s Guide (2018 Update)

Neoteck dac converter, it converts coaxial or toslink digital audio signals to analog l/r audio and connects to an external device such as an amplifier via 3.5mm headphone cable. Supports volume adjustment and stereo audio output, good anti-interference function makes the sound pure and clear, and there are professional audio amplifier chip and volume adjusting switch, allowing you to drive your headphone directly and adjust the output volume; besides, noise can be eliminated when signal input, and automatically mute while non-audio signal is input. Aluminum metal casing, comes with an aluminum metal shell which makes it durable, heat-resisted and high quality; and it can easily install and operate.

Great compatibility, it is lightweight and compact, perfectly working with any playback source with an optical (toslink) or coaxial digital audio output such as digital and hd televisions, satellite receivers, cd/dvd/blu-ray players and game consoles (note: it is incompatible with 5.1 channel signal such as dolby ac3, please set the audio output to pcm or lpcm before using and it can not work with computers). 192khz sampling rate achieved, it actually supports sampling rate at 32.44.1.48.96 and 192 khz, and 24-bit s/pdif incoming bit stream on left and right channels.

Supports mainstream digital optical/coaxial input, sampling rate at 32.44.1.48, and 96 khz.24-bit s/pdif incoming bit stream on left and right channels. Plug and play, no need to install drivers, easy to install and operate; also, compact size, easy to carry, ideal for home or professional audio switching. Warranty, every linkfor product will be backed with 18-month-warranty and lifetime customer support. Dac audio converter, it converts coaxial or toslink digital audio signals to analog l/r audio and available for connection to an external device (note: it is incompatible with 5.1 channel signal such as dolby ac3, dts, please set the output audio mode of the device to pcm or lpcm before using).

High-grade aluminum alloy design, overall shielding without signal interference, gold plated sockets, ensure high-quality audio signal to send. Multi-point connection, the adapter output rca l/r and 3.5mm jack simultaneously, you can play music and share at the same time.

Kindly note: the da21 will only support pcm audio output mode. It doesn’t support dolby, dts.5.1ch or 7.1 ch audio signals. Trouble shoot – if your getting a clicking sound – most likely your tv output is not set to pcm. Or if your getting screeching or no sound – most likely you are trying to decode dolby sound to analog. This device will not convert dolby sound. It is only a converter not a decoder. So make sure your device does not require dolby conversion. Converts coaxial or optical digital audio input to analog stereo output over rca and 3.5mm mini jack. Will not convert dolby digital signal. Make sure to change to tv output to pcm.

Supports all popular sample rates including 32khz.44.1khz.48khz.96khz and 192khz, at up to 24-bit resolution. Includes da21 converter, power supply, user manual.

Auto sensing input selection with priority given to spdif; disable / disconnect spdif input for coaxial; input application. Output: coaxial rca l/r + 3.5mm jack. Converts spdif optical or coaxial digital pcm audio input to analog stereo l/r rca or 3.5mm cable outputs ; supported sample rates including 32khz.44.1khz.48khz.96khz and 192khz, up to 24-bit resolution. Input: optical toslink spdif coaxial.

Note: please take off the protective caps of the optical cable and set your device audio output in pcm format before connecting. Inner special ic unit of amplify analog audio signal to ensure strong and steady signal out; ultra low jitter and high fidelity design using new receiver & d/a converter chip. Provides electromagnetic-noise-free transmission, and auto sensing input selection with priority given to spdif. Supported sample rates including 32khz.44.1khz.48khz.96khz, up to 24-bit resolution. Converts spdif optical or coaxial digital pcm audio input to analog stereo l/r rca and 3.5mm headphone outputs simultaneously note: please set your dvd or player with audio pcm model output; converter and transfer audio signal only, do not support audio decode.

High-grade aluminum alloy design, overall shielding without signal interference, gold plated sockets, enhance hd sound signals over long distance broadcasting smoothly. Supports mainstream digital optical/coaxial input, sampling rate at 32.44.1.48, and 96 khz.24-bit s/pdif incoming bit stream on left and right channels. 2-channel lpcm or pcm, supports uncompressed 2-channel lpcm or pcm digital audio signal output; provides electromagnetic-noise-free transmission(this dac adapter only support 2.1 channel, not for 5.1 channel and dts; if you need an update version, just search asin: b01mxj83g4).
