I want to achieve the following chain: TOSLINK -> I2S -> DSP -> I2S -> TOSLINK From the schematics this looks possible but then you write: "I2S signals and S/PDIF cannot be used as the input or output at the same time . Please turn off the input power supply when you switch the conversion mode." Please clarify. Thank you in advance

Hello, Pad. Thank you for your interest in our products. The description means this WM8804 signal transceiver board can convert S/PDIF to I2S and S/PDIF or convert I2S to S/PDIF. However, it doesn't support convert I2S to I2S. Wish this could help you. Have a nice day~

Can I use this "WM8804 S/PDIF AND IIS/I2S AUDIO SIGNAL TRANSCEIVER" in combination with the "Analog to I2S Decode Board -CS5343". I want to convert a stereo signal to an output signal SPDIF TOSLINK and I need the settings of the WM8804 board. What hardware connection is needed?

Hello, Robert. Yes. CS5343 decode board and WM8804 transceiver can be used together to convert analog signal to S/PDIF signal output. Please set WM8804 transceiver at slave mode (SW3 LEFT ON) and choose I2S input (SW4 RIGHT ON) through switches on the board. Wish this could help you. Have a nice day~

hi I am trying to transfer my oppo i2s dsd signal into my dac which only have USB and spdif Just wonder does you WM8804 S/PDIF AND IIS/I2S AUDIO SIGNAL TRANSCEIVER, takea i2s (dsd signal) and convert into spdif ?

Hello, Witon. Thank you for your interest in our products. Yes, this WM8804 signal transceiver can convert I2S signal to S/PDIF signal. Wish this could help you. Have a nice day~

I have this connected to a JAB5. The input signal to this is S/PDIF and all of my music files are 16 bit 44.1kHz. What setting must I use on SW5 to correctly feed the JAB5, please?

Hi, Frank. Please set SW5 on WM8804 at 48kHz, 24bit I2S master mode, and set JAB5 as slave mode. You can take this demonstration video for reference. https://www.youtube.com/watch?v=UAHUVEpnaHo Wish this could help you. Have a nice day~

Hello, I asked a question under the wrong product so I apologise. Can this board be input a 44.1kHz 16 bit file (CD standard) which has been converted to FLAC on my NAS? I think the software converts to a standard CD like signal. I use a Raspberry Pi 3B+ running PiCore Player, with a digital output hat, to send SPDIF (optical fibre) to an optical splitter and then to a JAB5 connected to this board. There is a JAB5 and this board in each speaker box. The JAB5s are configured to use the whole signal, however, for the stereo effect, one channel (left or right) is muted through Sigma Studio so only one channel is processed in each speaker box.

Hello, Frank. Thank you for your interest in our products. We are afraid that it's not able to be realized. Because both WM8804 module and JAB5 amplifier board will need MCLK of I2S signal, but Raspberry Pi cannot provide this signal. Wish this could help you. Have a nice day~

Hi, I want to use ADAU1701 board to drive an active filter to feed some FDA amplifiers for a 3 way speaker. My goal is to make everything Digital to the input in spdif of my FDA amplifiers. What do I need to get 1 spdif input going through DSP ADAU1701 and going out to 3 differents spdif out to feed my 3 amplifiers ?

Hello, Thierry. Thank you for your interest in our products. We don't have products that can meet your requirements. But we can customize for you if you are interested. MOQ would be required. You can contact us by email for further discussion.

I bought this board to use with a JAB5 but it did not come with a pin to pin converter as shown in this video on YouTube posted by Wondom; https://www.youtube.com/watch?v=UAHUVEpnaHo How do I get this connector?

Hi, Frank. Please kindly note that the pin-to-pin converter is not included in the package. We can provide you with 2pcs pin-to-pin converters for free. Taking freight into consideration, maybe you can place another order, and we will add the pin-to-pin converters in the package. Please leave us a remark after your purchasing. Wish this could help you. Have a nice day~

Hi, this is a very nice and extremely useful product. I got two, I am using the optical>i2s functionality to feed some avb modules with great success, plus solved some interconnection problems which troubled me here in my studio for long. However, I think that the gain levels are too high, to be honest marginally close to distortion. Is there any way to lower down the gain level at a somehow lower fixed rate? I guess someone will have to mess around with the firmware. I am not saying it is easy, but is this possible? Many thanks in advance

Hi, stamatis. Thank you for your kind feedback on our boards. Please note that, this WM8804 audio signal transceiver board only convert signal, it doesn't amplify the signal, which means it will output as much as the input, there is no gain control. The amplitude of signal is up to your input signal. Wish this could help you. Have a nice day~

Hello, I have an I2S input from the "CS5343 ANALOG TO I2S" board and a second SPDIF input from a raspberry pi (using a Hifiberry Hat). Is is possible to use this transceiver as a switch and pass any of the two inputs to the output via I2S to a JAB5 Amp? Would it be possible to switch between the inputs via my own hardware/software (for example using a GPIO pin from a raspberry pi or an arduino etc...)? Thank you.

Hi, Patrick. Thank you for your interest in our products. This WM8804 signal transceiver board can convert S/PDIF to I2S and S/PDIF, or convert I2S to S/PDIF. However, it doesn't support convert I2S to I2S. Wish this could help you. Have a nice day.

What are "+5V_IN" (on I2S input and output connectors) for?

Hi, Ihor. Thank you for your interest in our products. The "+5V_IN" is a position for 5V external power. If possible, it's suggested to power WM8804 signal transceiver board with a separate power supply. Wish this could help you. Have a nice day~

Thank you. Now, I understand it better. This board converts S/PDIF to I2S . And I2S to S/PDIF. Is there anyway to use S/PDIF to I2S. And I2S to I2S?

Hi, Shay. This board can meet your requirement on converting S/PDIF to I2S. However, we don't have any product to convert I2S to I2S. Have a nice day~

How can i2s input be activated? Output side has a switch.

Hi, Shay. To activate I2S input, you just need to plug in the connector and input I2S signal. Please note, I2S input signal can only be converted to S/PDIF output. You need to set the master or slave mode according to your device and set SW4 as AIF (I2S) TX Source. Wish this could help you. Have a nice day~
