ADA Mach 4......WOW!!!! - Page 37

I suppose you're talking about firmware upgrade, not a DSP chips change.
The Mach IV unit is 1y old, I didn't see any communication about what you are talking to.
A friend bought this unit 10 months ago, it s seller or Ada never call him back.

I know there was a PLII issue (supposed to be solved out with latest firmare).

There is one (major) remaining issue regarding the PEQ for the subwoofer output.

regards

I'm agree. The most important is how the boxe sounds.

AFAIK this was corrected on the HDMI 1.4 units.

Adam

Correct...

How many ada expert Adams are there in the uk, I collaborate with one, might that be..?

Does it ring a Bell?

LOL I am not sure I qualify as an 'expert', more of a 'busy-body', I don't think we have met though. I am the Adam who wrote this review of the Suite 7.1 HD a while back but I am just a punter, albeit a passionate one: http://www.livedigital.co.uk/2010/06...-suite-7-1-hd/

Cheers,

Adam

I thought you might have been Adam bell from smartcomm who toils with it.

Hi,

New question
Will ADA SSPs be upgradable to be compliant with the THX Media Director functionality ?

Regards.

I certainly don't want to hijack this forum, but since there are several knowledgable ADA users here, I wanted to ask if anyone has experience with ADA's HTR-2400 theater and multi-room receiver. It's a product that's been discontinued for a few years, but I have a couple questions about its operation if anyone happens to be familiar with it. If so, please send me a PM. Thanks.

What problem is that?

If you go back a few pages it is described in more detail.

Adam

How far? I tried 4 with no luck, I was looking for the discussion. Basically my suite 7.1hd has the beat bass ever and then the output is gone sometimes.

I don't know how far, I guess if you are bothered enough you will find it.

It isn't related to what you are describing though. AFAIK I am the only person who has noticed it, so if you haven't noticed it I wouldn't worry about it. I think something in my system makes it more obvious than most... It is a form of low level distortion that occurs when filters are applied in the PEQ.

Adam

Yeah, I just found it thanks. It was back 10-11 pages. I think mine is a different issue for sure. I lose lots of output during movies sometimes. It might be a HDMI EQ problem or something like that. The bass is still there but it seems it is holding back quite a bit for some reason like a limiter is on. I will get a hold of Ada on Monday but was just trying to figure it out over the weekend.

I doubt it is a hardware issue, more like (no disrespect) setup related or not the ADA, they are pretty bomb-proof IMO. Did you do the setup yourself or have an installer do it?

I can maybe check your HD Suite settings against my own if it helps?

Adam

PEQ low level noise when applying to sub channel or all channels?

All I believe but generally only noticeable in (very) bass capable speakers and at a very low level. Like I said I don't know anyone else who has noticed it, so it probably isn't worth worrying about.

The one on audiogon does not have that problem.

I set up myself but I did not use a computer. I first thought it was the HDMI cable because I swapped it out and the bass was back but then it went out again. I messed with the HDMI EQ settings(restored them) and the bass came back for a long time so I thought the problem was over but last night it happened again. I will recheck all the connections again because I just added new subs and the amp to power it. I still don't know how to connect this to a computer. I have the Ethernet cable hooked up through my modem.

I did not see one there. What are you guys using for amplification? I am using the MPA 500, a sherbourn, and a FP clone for sub duty.

I've setup several suite7.1HDs and Rhapsodys - all have PEQ engaged, none of those systems have low level bass noise. Each system has 3+ subwoofers and full range fronts.

MKtheater; are you maintaining RCA (unbalanced) connections throughout? What you're describing sounds like an installation problem.

Dan

I know it is something simple. I just updated the software to the PS3 so maybe I have to re-select the audio options again. I will make sure all the connections are secure and check the PS3 and let you guys know. BTW, Ada is my favorite and not by a little. I used to have the Meridian 861, krell, etc.... and I like the Ada.

It would be nice to have confirmation of that.


As originally described by Adam, it seemed to be the same problem I found in the SSP-800, which was an issue with the MDA DSP board's firmware, long ago fixed there (early 2010).

What makes it rather elusive is that the problem was not audible in the SSP unless 1) certain PEQ settings were used, 2) certain content was used, and 3) certain listening conditions were used. I think I was the only SSP owner to mention it in 1.5 years, although someone at Classe knew about it, too.

1) Use a gain of -6 to -10 dB or so, and a Q of 5 or higher, at a convenient frequency like 100 Hz to 1 kHz in a main channel (that's where I found it, anyway).

2) Input a sine wave at the same frequency as above. I used a test CD recorded at -12 dBFS, but the level is not critical.

3) Listen in a quiet room. Turn the PEQ band on/off, or adjust the Q to lower values (like 1) and see if background noise is present and changes. If so, that is the problem. If there is no noise under any condition, no problem. (The noise is confined to the channel, it does not spread across other channels of from sub to main.)


How do you know? Did ADA confirm the 1.4 units use corrected firmware?

I speak to the UK distributors regularly and they tell me the issue has been corrected in the 1.4 units.

Adam

I use PEQ with a q over 5 on the sub channel and have no problems at all.

Superb, Adam. Thanks!

I'm on the hunt of a processor with digital output (s) to drive active speakers via Coax-spdif.
I don't see mentioning this feature in the ADA's manual. But since this is a highly customizable device (so i read) I was wondering whether it's possible...

no, analog outputs only. At least no way to do what you're looking for.

sorry.

Theta and Datasat are the only ones that come to my mind.

Dan

Thanks... I am reading about them as well.
