Hifi shield Dac updated version

Post by audiotechguy » Mon Nov 07, 2016 7:12 pm

Will the hifi shield Dac get a new hardware update with new dac, I'm looking to get one but I'm sure what the audio quality is like, ill be creating a audio project but I want the dac to be integrated and not be a USB Dac or separate device, but some people say that he hifi shield Dac is not so great.

Is it a high end Dac or a low or midrange dac.

We launched a new DAC board HiFi Shield 2 a few days ago.

What is your target dynamic & noise specification of the DAC?

I guess I don't any requirements, other then low noise from the outputs and high dac quality chips and a flat true frequency response I'm going to be mixing and mastering audio. Is the hifi shield Dac good for such uses, I assume they have a flat frequency response

What's the difference between the new hifi sheild and the plus, I see a chart of the frequency response and it looks way off compared to the plus, why is that.
I'm going to be creating a project for audio mixing so I need a true frequency response,

They have different dynamic ranges (or SNR signal-to-noise ratio)
HiFi Shield + has 110dB
HiFi Shiled 2 has 115dB

Both have very flat Frequency response.

Is there a reason why the chart of the frequency response on the new dac seems to be not as flat as the hifi shield plus

Oh my mistake I was looking at the frequency sweep chart on the new dac, I mistaken it for the frequency response. The new dac has a frequency sweep chart and the old one does not.
Sorry lol

Also, I think the new Burr Brown DAC being used in the new HiFi Shield 2 supports hardware volume control, where the Shield+ only supported software volume control. This is a nice upgrade for sound quality.

Hmm hardware volume control, how would that work and is there a way to find out if it does support that,

Ya I was looking at the specs, I'm trying to figure out how the hardware volume control would work, does it mean I can make a volume button or switch and use it to control the volume

Via software I2C control to adjust the hardware output volume in the PCM5242 DAC IC.

There is a hardware volume control built in the DAC. The OS/Software sends the volume level then some magical hardware device in the DAC adds or lowers gain (?)....All I know is the HiFiBerry DAC+ Pro uses the same chip and sounds better than a board I had that used software.

I am kinda jazzed that HK released this. Hardware volume was the only thing keeping me from getting it. Now how about making a case that fits both the C1+C2 and HiFiShield 2.

Some other people have requested the case too.
But they wanted to integrate the 3.2~3.5inch LCD together to make a standalone player.

Time to hear more opinion.

I think the display could be optional if the case is designed like the CloudShell, simple have a different top plate.

I think it's a great idea.

Did I can use this plate on Odroid N2 for SPDIF output only?

I don't want DIY version. Want just buy, install and use.
So, this addon board will work with N2 or not? For spdif output.

ODROID-N2 is not a good form factor to put into with Hifi-Shield and it misses the pinout to connect with. Instead, you can consider playing with ODROID-C4 that can tighten with Hifi-Shield without hardware modification, but you would need to do some software work. Currently, supporting Hifi-Shield on ODROID-C4 is not available due to the software issue recently discovered but will be fixed soon.

I use N2 as is media box with CoreElec (4k, HDR, 10 bit). Want digital audio output for connecting with external dac.
C4 is less powerfull.
