Any suggestions ?
I prefere not to disclose the name.
It may be me who is not fit for complicated audio gear
Before buying this unit , the reviews that I have read were very positive about the sound of this processor.
Probably, those who wrote the reviews are audio specialist that know how to do the right set up..
I am well over sixty , l may be too old for technology.
My other audio gears are :
MC 8207 power amp
Rotel RMB 1075 power amp
Pro iDSD DAC Streamer
Cambridge 752 BD BlueRay
Focal Chorus 836 W As front
Focal CC 1000 BE as center
Dali Epicon 6 as surrounds
Epos elan 35 as rear
Keff R 50 as front height
Psb imagine XA As rear height
Monitor audio and PSB as Subwoofer
power cords are 2 PS Audio PerfectWave Ac 12 and 1 PS AudioAC 5.
2 power conditionner
LG DVD recorder
All interconnect are XLR by BIS audio
Buying everyting new would cost me about 60 000$
anything else, you would like to know?
I agree. There's not much we can do if you don't disclose the name of the processor. HT Processors nowadays are usually somewhat complex to setup. The EQ function can be challenging to work with. It sound like the unit has a fully parametric EQ/filter mechanism. This really requires in depth knowledge of acoustics and frequency response. It may be that you need somebody with RTA software, such as Room EQ Wizard (REW), to measure what each channel is doing.
That being said, if you're not getting good sound out of it, then a few possibilities:
1. The unit is brand new and needs to be broken in (burn in of all electrical components). Give it 100-200 hours of constant running before making a decision. Since the unit is fresh, it could sound bright/harsh/thin and without bass. It can go through many changes during break-in.
2. The unit could just be poorly designed. I have actually had a couple very expensive processors in my system that just could not cut the mustard (contrary to many other opinions). One was a Theta Casablanca IV, which was very expensive and came with Dirac room correction. I just could not get it to sound good - it was very bright/solid-state/sterile sounding and just did not even come close to sounding as good as my very old Krell HTS 7.1 (the Krell just sang!). The other was the Bryston SP3, which I could appreciate, but was too laid back in the mids/early highs to be exciting and engaging enough. I think the Bryston had a poorly designed DAC/digital board (they used a generic off-the-shelf DAC/DSP board solution).
3. The new HT Processor sound could just not be the type of sound you're looking for.
What processor did you use before?
I usesd an old Rotel RSP 1069 who went out of order , twice this spring.
My new processor is Acurus ACT 4 by Indy Audio Labs
But I do not want put the blame only on the unit.
l have admiration for the two co founders who bought the electronic section from Klipsh in 2009.
I E-mailed theme about the poor sound quality of my unit ( their new baby )
they asked me about my speakers and my sources.
It has been Three days now ,And I haven’t heard from them.
Sory,for my bad temper
Dolby builds professional gear and it's possible that they use trickle down technology throughout their entire line of processors.
On the website it states some of the features:
The audio and acoustic engineers who use this type of gear also have a background in music or play an instrument.
I would like to underline that audio gears is the most expensive material thing that l own.
I drive an Mazda B 4000 4X4 1999 pick up truck.
Music is important in my life, for many reasons.
A bit like the link below ( but not as much )
Hi zzrider - that ACT 4 is so new that I don't think anyone here has direct experience with it. I was also asked about this processor by a friend and I could not comment on it. There aren't any "internal pics" on the net to show us how Acurus has architected the electronics. It's so difficult to say what your problem is. I would suggest:
1. Let the unit run for 100-200 hours (maybe 8 days straight) to burn in all the electronics and electrolytic capacitors. You are likely to get a significant change in sound quality - usually an improvement. Then make a decision.
2. Think about what it is that you don't like about the sound. Is it a bright/sterile character that you don't like? Or is it a lack of bass or certain frequencies? Maybe you can learn more about the parametric EQ in the unit so that you can tune certain frequencies.
Give it some time and try to work with the unit. I found that sometimes I have had to sit with something for a couple weeks before I decided on whether it was good or not.
Thanks a lot, auxinput.
the sound is very bright and very harch.
No matter the source, power cord, audio mode. Even in stereo mode
( two channel ) the sound is very .unpleasant.
l am going to follow your advice, take some time, calm down.
After all , there are worst things in life.
I appreciate your effort for my case
Auto room correction varies a great deal in quality. For the best results you need to take multiple measurements so you get a good average.
Bass modes in particular are poorly treated by an eq with a single mic reading. For this, you need bass traps and multiple location measurements. Actually, room treatment always helps and often helps EQ work better. :)
can someone explain to me why whenver I ran any sort of EQ, it just made my listening sweet spot smaller, and the bass really messed up if you stood up? sort of like it applied some kind of effect where the bass was really loud as if my head was at the back of the room.@d2girls - this is pretty much the same experience I had when I was trying to get Dirac room control setup. It does funny things to the phasing and frequency response so that the audio sounds like it's in your head instead of way out in front of you. Some of these room correction systems try to affect phasing because they are trying to fight room nodes or first reflections. The end result can be poor audio quality.
Setup should be as follows
#1 Speaker Size / Crossover points
#2 Measure distance with a tape measure
#3 make sure the EQ profiles are set to flat.
In order to FULLY configure an ACT4 You will need to do some room measurement.
Bright and Harsh could be because the low end is getting rolled off / not configured.
Speaker Layout Screen: To setup the ACT 4 output configuration according to the particular speaker layout in the room, simply touch the buttons corresponding to the room loudspeaker positions. The layout screen indicates the layout description in industry-standard numeric terms on the lower right as changes are made. The audio bed section determines which ear-height loudspeakers are enabled. The height section selects between top front, top middle and top rear loudspeakers or none. Upward firing or “dolby enabled” speakers are selected here as well. Finally, select the number of actively driven subwoofers in the system (up to three). Changes are made to the ACT 4 and its audio output immediately in response to layout changes on this screen
Speaker Layout #1, Distance are there, Appropriate crossovers and sizing, start with 80hz.
Thanks biudrain , l appreciate
But every things you wrote ,have already been done, properly.
what do you mean by : ...the low end is getting rolled off / not configured.
l have to admit that I am not perfectly bilingual. French is my first langage.
the sound is harsh , bright and not very detailed.
anyway,if it does not improve , I can always try to sell it.
I am going to loose money but it is still better than loosing my mind
As l wrote to auxinput : No matter the source, power cord, audio mode. Even in stereo mode
( two channel ) the sound is very .unpleasant..
BlueRay ( HDMI ) , Pro iDSD streamer DAC (XLR) and DVD Player (coaxial ) are already set to bitstreem.
According to the owner’manual, stereo mode is the best audio mode of the ACT 4.
I have an other issue with the unit ( the third ), l E-Mailed the technical service yesterday. Until now, I have been answered by the co founder of the company.
But I haven’t heard from them ( about EQ tuning ) for the past 4 days .
I am affraid , if they learn about my thread here, I will not be on their beloved client list.
Before ,posting a discussion thread here, I have tried everything.
talking to me about those items is the same to me than talking Norwegian.
The owner’s manual identifies those settings ,without explaining what they are and what it does.
My understanding , as I mentionned to the co founder of Indy Audio Labs, is that the average client who buys that expensive kind of audio gear is not 20 ,30 or 40 years old. At this stage of their life, they have other priority with their money.
The 50 years old and over costumer, on average, contrary to the kids today, is not a electronic or computer wizard. He is not an audio engeneer either.
In my honest opinion.
It is also the opinion of Gordon Shackelford – Krell as mentionned
on this tread.
Rick Santiago, co founder and chief engeneer at Indy Audio Labs
send me an E Mail this morning with extended informations about EQ settings.
He gave his setting recommandations ( frequencies-gain- bandwidth - low shelving filter- high shelving filter )for the kind of sonic experience I like : classical music , accoustic and brasillian accoustic jazz.
IMHO , it is out of reach for the average audiophile.
You better have a good and toughtful dealer .
The sound is very good
There is another ACT 4 in my place.
Thanks everybody for you help
