I just wanted to start a feeler to see if anyone else is having this issue. The PS8 works flawlessly when it's warm. Over the past couple days when I go to work and the temperature is in the 30s it lets out these extremely loud pops mosty though the tweeters but also through every speaker but the subs. It sounds like a large rock hitting the windshield at 80mph. It's the kind of pop that blows speakers, no a subtle click (it does that too during it's episodes but I'm not worried about that). It does a series of pops for about 10-15 seconds and then it's fine again. During this time, music plays just fine. I have made no changes to the PS8 or the entire setup. Laptop is not plugged in. In the evening when I go home and temps are in the 60s-70s everything is fine. My passenger side Esotar tweeter might be toast so this could be a $1,800 problem is that's the case. PS8 is coming out, I'm not about to attempt to troubleshoot and lose more speakers. I pulled the main system fuse and I guess I'll be without a system until this gets resolved. To say I'm disappointed is an understatement.
Try calling the fiancée because you can't remember if you take a right or a left on a route you've done roughly 900 times. The silence has been really nice... seriously. I've had the flu for 3 days each day has been worse, no idea how bad its going to get but this is really not cool. I also parallel parked this morning and took my bumper down to the urethane against a really tall curb. It needs to be replaced. I never screw up driving, first scrape the car has ever had and I haven't had the energy to get angry about it. I MUST get those tweeters a member bought shipped tomorrow so I'll get the PS8 shipped as well. I'll let you guys know.
We had 2 units with Cold Weather Popping. We contacted Fred and we sent the 1st unit out around the end of November. I believe he used ours as a guinea pig it might even be the one in the video. Anyway we received it back last week and it works flawless in cold weather. We also performed an OP amp upgrade per Fred's recommendation we choose these:
What a difference this made its unreal !! Thanks FRED !
I sent the 2nd unit in today overnite. Fred even offered to turn it around quick so we have it ready for this weekends IASCA event at the shop.
Anybody who is having issues call the dealer you bought it from get it taken care of its there job as a dealer to support there products they represent ! If they won't help you call ARC send it in get it warrantied END OF STORY !! ARC has bent over backwards to help us out with this issue and many other things no questions asked !! :beerchug:
LM4562 are awesome! I used them in several of my amps . I suggested them to Fred when he was doin the Opamp test...and they went on to win.
the stock 5532 are very nice opamp as well for audio.
Arc Audio has a video of the PS8 cold weather testing. here is a link. Below 0 degrees and performs fine. Popping could be from the amp turn on delay in settings. even after a software update this setting may require adjustment to allow amps and other electronics a delayed turn on. The video link allowed me to view it without being a facebook member. Hope this helps!
Almost 15 years of being an installer and learning how to use my ears to make vehicles sound good for my customers/friends and what have i learned?
That the ARC AUDIO PS8 is the finest Audio Tool i have ever ever had my hands and ears on. It has completly changed the way my personal vehicle sounds. The Team at Arc Audio has always been there to anwser any questions or concerns that i have had. They really are a company who cares about this Car Audio Lifestyle. Yes i call it a Lifestyle.
I have been dealing with Arc Audio for about 4 years now and If there was ever an issue with any product they fix it. END OF STORY.
Arc Audio has the best team of people i have ever worked with. There Product knowlegde and Tech support to me is priceless. So dont hesitate to call and ask about your issue. They will make it right
I have installed and tuned with Rockford 360.2 -Audison BIT one- Helix Pdsp- and now the ARC AUDIO PS8.
ALL I CAN SAY IS THANK YOU ARC AUDIO FOR PUTTING A SMILE ON MY FACE EVERYTIME I GET INTO MY CAR.
yes-How many of them I can't say- However I know the first one to go to arc for the issue was tom's and it came back and seems to be working flawless from then on.
And with the op amp upgrade it makes my se's sound even better.
I've got to get mine sent out... I know I keep saying that but sooner or later my $1,900 (retail) tweeters are going to be blown when I forget to unplug it or warm it up. I decided to listen to the stereo today. 2 minutes with the fiancee's old pink hairdryer that I keep in the trunk before starting the car and I was ready to go lol. Money is a bit tight for the next two days. Maybe Monday.
I doubt a little criticism we'll stop production of anything.
Does anyone know if the PS8s coming of the line today have the op amp upgrade already done?
all PS8 come with opamp sockets so u can roll your own standard dip8 opamps into it. doing so voids warranty, but the option is there for SQ enthusiasts.
So lemme get this straight? An OP AMP was causing this popping. Because man, I have pulled every op-amp ever made out of a near zero degree (F) box truck into a humid, hot venue and have yet to discover this popping issue, condensation and all.
Andy would have been nailed to the cross...and was/has been hung up there. But the PS8 guys, even ones who haven't used the processor are fanantical in the opposite spin way with this processor.
That guy goes above and beyond to help and it's greatly appreciated throughout our community. Arc has great in-house customer service but It would be nice for them to appoint someone to support their products in the same way. One would think it would pay for itself in the long run.
Agreed about the help provided by Andy on the MS-8. His attendance on this site was a major reason for me in going with the MS-8, and staying with it since. I cant\wont speak to the PS-8 as I havent used one (and cant say as I feel the need). I do like the Arc amps and run one. Without bashing Arc or its products, it would be awesome to have a presence of sort on this forum. I cant imagine too many places where an Audio company can get as much "visibility" in its market as on web sites like this one.
But I do taxes this time of the year and get roasted on a daily basis over why the IRS hasn't either gotten their money to the people on time (last year) and why we have to wait until the 30th for them to accept the returns.
So yeah, I would go to help people that appreciate it though I have to wade through the sea of idiots and assholes.
I don't get why/how JBL poured their heart and soul into the their processor (which was under development for many more years than the PS8) that is is ok to roast them while the Global Product Manager is here catching the heat helping any and everyone...but you aren't going to stand by and let someone say something negative (but true) about the Arc processor with no factory support on here.
Coming from using proaudio processors...I guess I am still missing what makes this processor so magical and untouchable. And I like Arc, the people are great...I've personally have known Fred for what, 10 years now?
100% agree, and I too have high expectations, having used pro audio processors as well.
Addendum: I would like to add that if I ran Arc Audio, I wouldn't be on these forums either... **** that. Andy is a masochist, and his relentlessness borders on insanity.
Why would you expect anything different? Delay resolution is determined by sample rate (1-sample is the minimum amount of delay) and the rest are simple IIR filters where the biquad coefficients are calculated using your entry. If there's no limit to the number of decimal places you can enter, then it'll be pretty difficult to figure out where the coefficients are rounded. Digital EQs are different than analog EQs, especially when they operate like a calculator and you have all the keys exposed for input. In Analog EQs, the resolution is often much poorer and filters interact with one another to create unintended results. For an example of this, go grab a 31-band EQ (you can probably do this with most digital EQs too) and boost all the available frequencies by 6dB. Then, measure the output. What you'll probably expect to see is a graph where the frequency response has been raised evenly by 6dB across the spectrum. What you'll probably see is something VERY different.
Congratulations to Fred and the guys. Developing these kinds of products isn't simple and the testing that's required to make sure things don't crash under any of the millions and billions of button-press combinations in the several interations of the state machine is a huge piece of work. Looks like a nice piece of gear.
Kudos to the Arc guys for providing what looks like really high resolution EQ tools. Now it's up to users to be successful. The trick in EQ-ing isn't about being able to reduce a peak with a Q of 100, it's about interpreting your measurement according to what's audible and detemining the best way to correct.
The THD looks great.
I would be very surprised if the t/a was off considering this is a digital signal processor. I would also be surprised if EQ cuts/boosts were off.
Could you measure all 8 channels at 0db using a 1khz tone, to see how close they are matched?
Also, if you have the time, a confirmation of the signal to noise ratio at 0db (8vrms) would be great.
Finally, on the PAS review, the graph for crosstalk vs frequency starts at 600Hz, while every other measurement is shown from 20hz - See here, it's on the last page
I have no idea if your setup allows you to measure this, but if it does, I would love to see what's below 600Hz.

I swept all channels for channel to channel matching purposes last night but didn't post the results because there's nothing to "see". All channels measured the exact same. If I posted that all anyone would see is a single line. Lol.
