Features

Digital-to-Analog Converter with ARC: The CS-DACA is a digital-to-analog converter (DAC) that converts 2-channel PCM digital audio signals to analog stereo; or allows 2-channel PCM, Dolby Digital or DTS to pass-through digitally. It features a combination of digital inputs, as well as a variety of analog and digital outputs.

Supported Audio Formats: The CS-DACA digital-to-analog converter supports 2.0ch PCM, 5.1ch PCM, Dolby Digital, and DTS. However, only 2.0ch PCM digital audio signal can be converted to analog stereo. 2.0ch PCM, 5.1ch PCM, Dolby Digital, and DTS cann all pass-through digitally.

Inputs: The CS-DACA is outfitted with a HDMI ARC jack, optical (toslink) digital input, and a coaxial (SPDIF) digital input. A 3-way switch (labeled A, T, C) on the digital-to-analog convert allows you to select which input to use. Once selected, that input's audio will be transmitted from all connected outputs.

  • "A" Selector: HDMI ARC jack
  • "T" Selector: Optical (toslink) digital input input
  • "C" Selector: Coaxial (SPDIF) digital input

Note: The HDMI ARC jack only support audio transmission (video is not supported).

Outputs: The CS-DACA is equipped with analog & digital outputs. There is a 3.5mm headphone jack output and a stereo RCA output, as well as a optical (toslink) digital output and a coaxial (SPDIF) digital output. All outputs are live at the same time and the selected input source's digital audio will be transmitted from all connected analog & digital outputs.

  • 2.0ch PCM, 5.1ch PCM, Dolby Digital, and DTS can pass-through the optical or coaxial digital outputs.
  • Only 2.0ch PCM can be converted to analog via 3.5mm headphone jack or stereo RCA outputs.

Power Requirements: The CS-DACA features a DC port and comes with a 32" DC-to-USB cable for powering the digital-to-analog converter using a USB/AC power adapter (sold separately) or free USB charging port on a computer, TV or other device.

Note: The CS-DACA does not come with an AC power adapter.

Customer Q&A

6 questions already asked

Q
Would this be considered an audio extractor with a DAC (digital-to-audio converter) built in? And also does this product support HDMI ARC CEC (Consumer Electronics Control)?

Hey Justin, thanks for the question. This is indeed considered an audio extractor with a DAC on board. It does NOT support HDMI CEC however. To get an extractor with CEC, the only one I am aware of is this one from Simplified: https://www.crutchfield.com/I-rET1c402/p_297AUDEX2A/Simplified-MFG-AUDEX2ARC.html

Q
I tried a similar product from Amazon that did send audio from my Samsung TV (Arc) to my Sonos Playbar (digital) but the TV remote would not control volume. Would this product have the same issue? Thanks!

Greetings Scott. Thank you for your question. When converting HDMI to another type of output you lose the handshake that HDMI has that allows a TV remote to control a second connected device. Now with that said the Playbar does have an IR sensor, and if the TV's remote uses IR, that remote can be programmed to operate the Playbar. The key would be is your Samsung remote IR, or Bluetooth. If its Bluetooth, its not going to work.

Q
My tv has toslink or coax audio out only. I am looking to use a DAC to allow me to use my equalizer while listening to tv broadcast. Will this work for the application? I've used a couple of other converters which worked for about a month but then just quit.

Greetings Drew. Thank you for your question. This will work for your application. It also has HDMI ARC in and you are paying for that luxury. If all you need is Toslink, or Coax digital to RCA analog, you could get the CS-DAC. https://www.crutchfield.com/p_120CSDAC/Ethereal-CS-DAC.html?tp=59309

Q
Will this work for connecting a 2019 Sonos playbar without a hdmi port (only has optical cable) to a new Samsung smart tv that does not have an optical port (only hdmi ports)?

Greetings Kevin. Thank you for your question. This device has the capability to convert HDMI ARC into optical outputs, it can also send HDMI ARC via COAX, or convert that ARC into analog as well.

I have copied the dimensions listed on the webpage for the Ethereal CS-DACA for you below, Amanda. 3-13/16" Wide x 7/8" High x 3-1/4" Deep I hope this helps!

Q
If I use Toslink input will I get Toslink Output along with RAC output? Is Toslink works like pass through? Is RCA output variable?
artem  Jul 18, 2023
1 answer
A
That is an excellent question, Art. The CS-DACA is equipped with analog & digital outputs. There is a 3.5mm headphone jack output and a stereo RCA output, as well as a optical (toslink) digital output and a coaxial (SPDIF) digital output. All outputs are live at the same time and the selected input source's digital audio will be transmitted from all connected analog & digital outputs. No outputs are variable.
