Minidsp Flex Review (Audio DSP)

[diablo]

When power comes up again after power loss, unit reboots and stays on.
Which indeed can be annoying.
I am using Logitech Harmony automation.
When power comes back, I have to put the unit in standby otherwise next time I use it, my harmony activity puts in in standby.

I'm also using a Harmony in my lounge and have the same minor problem. I doubt they will bother adding on/off codes from this thread on the MiniDSP forum -

Separate IR codes for "power off" and "power on" instead of "power toggle"

Hello, I'm using a Logitech harmony remote to control my miniDSP Flex. I am using so called activities to control mutliple devices such as an integrated amplifier, TV, miniDSP Flex. There is only a single "power toggle" button for miniDSP Flex and that is not sufficient for all cases. Does...

Thanks for the replies.

When the device gets automatically on after power is reconnected, then this is not good, but I think maybe I can do there something with a smart plug and my homeassistant instance, as I use that already for my stereo system for other devices.

I want to replace my C658 as the software getting me on my nerves, so I need a good replacement for it.

Some question about the Balanced and Unbalanced Version of the Flex:

Does somebody use the MiniDSP Flex in the Unbalanced Version in a 2.1 Setup with a Hypex NC252MP Class D Module?

I want to know if the 2V of output voltage of the Unbalanced Version is sufficient to drive the NC252MP to full output.
My subwoofer only has RCA inputs and currently I don't have any hum issues (maybe cause TV and BluRay is only connected via Toslink), hope that will be the same with the Flex Unbalanced.

I want to know if the 2V of output voltage of the Unbalanced Version is sufficient to drive the NC252MP to full output.

Amplifier output voltage = input voltage * 10^(Amplifier gain in dB/20)

and

Amplifier output power = output voltage^2 / load impedance in Ohm

Here's a handy spreadsheet that combines these:

Fosi Audio V3 Mono Amplifier Review

That's amazing, thanks for the review. I would pair three of those with an Onkyo rz-50. Since I have to buy cables anyway, are there any benefits in going rca-xlr vs rca-rca? According to Amir's review of the rz-50, it can output up to about 3.5 volt

If I take down a peak at 28Hz and one at 57Hz, but when I do that, a dip at 38Hz is also lowered by -1.2dB. If I put a boost in Flex of +1.2dB at 38Hz and overall level is 0.0 in Flex device consoe. Have i anyway reduced headroom and increased the risk of clipping Flex?

This feels like a dumb question.

Could I put a Flex Digital in front of a Wiim Amp Ultra and use the PEQ/timing at least? Diraclive?
Since the streaming is done later, it would be an 'empty' signal but maybe that doesn't matter?

The Wiim would do subwoofer crossover. I can't use a Flex Digital for that because it has no analog out.

You cannot do that.

Your miniDSP Flex digital can still be bass manager--just attach an inexpensive yet transparent DAC to output 3/4, such as SMSL SU-1 or Topping E30 II and then attach the sub to that. Then you can feed the miniDSP using a digital connection from the WiiM.

 

[Luvchampagne]

Agreed. Once flex digital is m doing dsp the wiim ultra is just passing a Src digital signal. No peq or sub xover. I've been struggling through that. At least since it is digital you're not adding another adc dac cycle.

You can do WiiM Amp Ultra->USB->Flex Digital->External DAC + Amp->Speakers

Or you can do External Streamer->Flex Digital->WiiM Amp Ultra->Speakers

But you cannot stream to the Amp Ultra, use the Amp Ultra's DAC and Amplifier, and add Dirac Live.
For that, the Amp Ultra would require a Pre out/Main in connection like on some traditional Integrated Amps.

Very close to my system. Dirac works like a charm.

Better if minidsp adopted Dirac ART

Just DLBC would be good. Not sure whether any of their two input models are technically capable of it though.

Can you imagine Wiim teaming up with MiniDSP

They have said it's unlikely because It would require rewriting the code base. Same reason they can't incorporate Dolby digital 5.1 open source. They do not publish a roadmap and on fact are very secretive so no one can say for sure.

I'd bet Wiim has a 2 in/6 out that supports Dolby before minidsp does. DiracArt, I have a hunch, is not in the future of either company.

I actually see WiiM as potentially the future of this objectivist middle ground prosumer sector. Instead of just talking about things, they’ve been just bulldozing their way through really significant obstacles.

Quietly adding DD to some products and then rolling out very competent room correction for free, with no fanfare on even their lowest tier product (WiiM Mini) was kind of a mind blower for me.

I’m praying they enter the HT Pre/Processor space.

I'm not expecting DLBC or ART on any current miniDSP products.

If they did have any thoughts of producing a replacement for the SHD then that's where I'd wonder about DLBC being added. Personally I don't actually want DLBC as I'm happy doing things manually but it would be a good option for most.

I imagine it is more likely that they become competitors. It would be a cinch for MiniDSP to add streaming ability to their products, just as it would be simple for Wiim to expand the DSP capabilities in theirs.

SHD has streaming?
