Just curious, what is the bitrate of this processor? It looks like the MiniDSP is
24 bit ADC/DAC resolution / 48kHz sampling rate
Does this zoudio amp work the same way ?

I'm not Zoudio, but from what I read, the board is set up for 48KHz. I think he could have set it up for 96kHz but then it will be limited to only 2 biquads per channel instead of 5. You can set up to have direct i2s input to bypass the ADC. Most excellent sound!! There is no DAC on the board, i2s goes directly to PWM to output stage.
wired I2S/coaxial/optical digital input
Until there's a SPDIF coaxial/optical input availalbe, this is exactly what I'd like to do as well - please let me know how it goes!
Lutkeveld,
Are there plans to offer a daughterboard/similar to add wired consumer digital connections in the future? I'd jump on this immediately once available to interface with my existing Squeezebox/NAS based home streaming application.
Best,
Tal

@hoxuanduc . Great to hear that you like the amp! Postage delays are a mess with covid, but it is what it is..
@illnastyimpreza The amp runs on 48k by default, but the amp is capable of running at 96k with limitations in the DSP. With the Bluetooth connection, the digital stream is directly fed into the amp. For the analog input, the 24-bit ADC from the BT module is used.
@taloyd There are plans for USB integrations. Other digital inputs nots so much, but as long as you can convert it to I2S, it can be fed into the DSP/amp section, bypassing the BT.

Hi Jesse,
Looking forwards to this new software release!
Quick question though - how do you achieve the specified power output of 4 channels of 62w @ 4r @ 1% THD, when the tas5825m data sheet shows 2 channels of 38w @ 4r per chip?

Cheers,
Its measured using pink noise with 10dB crest factor to simulate music. That is why it says "thermally limited" in the datasheet, it cannot sustain that power using a sine wave.
But to be honest, it's a bit of a wild claim without giving any measurement details. I will put it on the to-do list to update those measurements with more detailed conditions.

Good evening,
I just received my two boards, nicely packed!
I need to go TWS how do I do that? I did see there are cables marked with TWS coming of the board.
Thanks
Peter

The wires can be used to hook up a button.
1) Power up board 1
2) Put it in pairing mode (long press volume knob)
3) Pair your device
4) Power up board 2
5) Press the TWS button on both.
The boards will search and find each other.
The TWS light on the right side of the board will light up.
The bluetooth stream will be shared after that 🙂

Thanks fort the reply: and one more question.
I need to use analogue in to run my REW signal to the amp so... How do I change from BT to analogue in?
Thanks

Or an alternative, it is obvious that you would need to run REW from a laptop or PC, then chances are it will have bluetooth. So connect the bluetooth of your laptop to the bluetooth of your amp.
^ I have lots of laptops and desktops, all newer than 3 years old....none of which have Bluetooth 😉
That is a great option though !

I work with a PC and a Mac, spaghetti of cables yet once connected it was super easy!! Love this as I have had Behringer DCX, MiniDSP 10HD, Hypex dsp on the long run all a hassle, separate amps /volume control and setup difficult. This was a joy to set up.
What is the downside (first impression!) BT gets lost from my iPhone 11 so I have to pair again. It is not possible to work with 2 different iPhones on the system as it is with for example my Bluesound Powernode.
Sound wise, still a lot of work to do on my filter yet first impression is good!

1) What would you suggest to get a better sound quality
analog input with decent external dac
or IIS input?
2) What is the easiest way to add remote volume control to the board for the IIS signal input?

Hi,
I read about this amp and ordered it at the end of January, it just showed up today, which is good speed to arrive in Australia. Nice packaging.
I was intending to use it for 2.1 (as in the expected meaning of 2.1 stereo!) to replace my existing 2.1 TPA3116 amp.. but after reading through the thread I'll set it aside and wait for the 2.1 stereo software update before proceeding, beyond maybe some quick tests to check it works.

Correct, lutkeveld is working on the software for setting the board up. He is overhauling the software somewhat to include stereo 2.1, ie subwoofer + left and right.
I imagine he must be pretty close to completion. We will need to wait for and update from him.

@Peterhenk. Amazing, thanks for the kind words!
@Defo Thats currently not implemented, but should be relatively easy.
If someone has a good suggestion on a general purpose IR audio remote, I would consider implementing it as an unofficial supported feature.
If somebody finds a suitable software library and can make an arduino take an action based on IR input, it would be relatively easy for me to copy into the amp firmware.
@Ddd_rus
1) IIS input, saves a conversion step.
2) See reply above
@everybody
About the 2.1 configtool:
I will release a beta version of the new configtool next weekend. It will be a temporary release that might be unstable. Nothing can be bricked and firmware can always be rolled back to a stable version.
I dont want to release it directly to the public because of the pretty big overhaul in the command structure. Once the release is stable it will be available on zoudio.com/configtool.
If you want to be part of the beta-test group, please send a mail with "2.1 configtool" as the headline to info@zoudio.com

I ordered this AK4118 SPDIF/TOSLINK converter to I2S.
It was the cheapest board with AK4118 receiver I found there.
I just hope that one is a better performing chip than CS8412/CS8416, DIR9001, WM8804/WM8805.
The latter should be good enough also.
Another options are
LCD equipped board.
OLED with amanero socket? Not sure is it pin compatible with original Amanero.
These are not my recommendations, just findings. I know nothing about quality of these boards and can only make a guess that these are boards that would work as an optical and coax converters for the ZOUDIO AIO4CH I2S input.
I need a TOSLINK to match a TV optical output (48 kHz?).
