MiniDSP Flex HTx

Is it possible to program a harmony remote to change the center channel level with one button?
Some movies have a lower level dialogue than others and in order to boost the level temporary I use a harmony remote (has been programmed) with my Emotiva XMC-1, is it possible to do the same with Flex HTx?

You could have a movie preset, there’s 4 programmable presets available. Then you can just use a controller to select it. But as for adjusting a channel volume on the fly, no.

Generally MiniDSP Flex HTx is good DSP and DAC but software on it have only 10 PEQ per output channel. I need about 20 PEQ per channel, my current DSP have 15 PEQ on channels and I miss some to get better correction.
Did anybody know, can Flex HTx PEQ amount per channel be increased with some option?
Is input PEQ only for stereo pair and it is located before channel routing?

10 on input, 8 in crossover, and 10 on output. So if creative you can get 28/channel

It’s not really input EQ as its after channel routing

Great.
Can 48 kHz sample rate improved with some option?
Are 28 PEQ per channel also available with Dirac Live?
Can Dirac live used also when Flex HTx is used for multi (4) way stereo system?

 

[dweeeeb2]

No
Not sure, maybe just 18.
Not sure, will depend on what Dirac package you use.

Why do you need 20 PEQs/ channel? The more I experiment, the fewer filters I use. I mean, I used to think I wanted more, but now I am using maybe 4 PEQs on some channels, and no PEQs on others....on my 4 way active speakers.

To hopefully clear up confusion, there is one input PEQ per input channel, so in a standard multichannel setup you have 18 PEQs per channel.

But it can be confusing, because the HTx can do pretty much anything you can imagine doing.

Actually not clear at all. If I need 8 channels, then 1 PEQ from input, 10 PEQ from output makes 11 per channel.

dude.... It is all in the manual. Picture and everything!

Input PEQ tab:



click on one of these channels goes to here:



Then your output PEQ:



Select the output channel PEQ and you get:




So yeah, it is actually 20/ channel if you do 8 channels in and 8 channels out.

But why do you need 20? That is what we want to know!

General question for this thread:

Is it an acceptable use case for this product to go HTPC —> x3700 HDMI OUT —> Flex HTx if I my only two surround sound sources are Xbox and my HTPC and both can be configured to do the surround decode internally and just pass 7.2ch LPCM to the Flex?

My thought process is that I will be upgrading the DAC and gaining about 10db SINAD by switching to the HTx, gaining Dirac Live if I want it over Audyssey XT32 and gaining stackable PEQ per channel if I need it.

Thoughts?

I think the best choice would be to run everything to the TV via HDMI, and have the TV to switch inputs. Then use the eArc HDMI on the TV (or Toslink?) to send audio to the TV.

You have to find the right setting on your TV to pass through the decoded audio signal. But it does work this way.

However, it only gives you 7.1 surround. You would probably need to add one of the small stereo minidsp units to the subwoofer output if you want to optimize 2 subs. Dirac will see them as 1 sub, though.

One useful feature is that eArc gives you a "virutal" trigger when set up this way, because the HTx can automatically be power off with the TV (through the HDMI eArc signal). And the HTx has a 12v trigger to control your amplifier.

The x3700 does just as good a job at HDMI switching as a TV, and at least I 100% know it’ll pass through the 7.1 channel LPCM I decode on the Xbox and HTPC via KODI. Why do you think a TV would be better.

The x3700 is able to select per HDMI input whether you want the output device to be itself or the HDMI output device which would be the HTx.

Also, my actual config is 5.2, since there’s 8 channels, what’s stopping you from configuring two sub channels with the HTx?
