Marantz AV8801 Preamp/Processor Official Owner's thread - Page 29

post #841 of 11290
FYI, I just received a reply from Marantz about whether the 12V triggers could be configured for PULSE or CONSTANT/LEVEL. The answer is "NO", the 8801 will only output a CONSTANT signal. That's too bad for Proceed and a few other amp owners. Apparently CONSTANT is more common so this is probably not a problem for most people.

Also, there was a question earlier that I did not see an answer to--"is the OSD routed to the video when you bypass the internal video processing"? Does anyone know the answer?

And like everyone else, I am looking forward to reading all reactions from new owners with great antici.....

Thanks for your help.

If it is like the AV7701 then no OSD is present when you turn off video prcoessing. If you press menu then the menu appears and the picture for the input you are watching disappears until you quit the main menu. On the plus sie it is quick to switch and lock with video processing disabled.

Even though the receiver is constant 12V out (normal) you could add a one-shot circuit that would do a pulse. This would solve the issue and is easy to do. Just search ebay for a "pulse timer module". Problem solved. About $12 and nothing to build.

I sure do hope the 8801 will work better with my system. The MC12B was dead quiet because of the fully balanced XLR circuit I am sure.

If you've selected an input with no signal and you are hearing an audible hissing noise which isn't due to the equipment having different grounding, then you have a defective unit. You shouldn't be able to hear any noise unless the volume is up at max and your ear is almost against the speaker.

Edited to add: For example, I have an AV8003 pre/pro feeding an MM9000 5 channel amp with standard 6 ft RCA cables. It's silent.

Disconnect all inputs and then test for noise. If it is present then you do not have a source-related issue.

Cool, what shop in Montreal did you order it from and what was the price?... if I may ask. The Canadian Marantz website still doesn't list the Canadian MSRP.

I was thinking I might have a defective unit. Thanks for your input.

With all inputs disconnected, I still have the noise. It does not matter what the volume is either. When I turn off the preamp while leaving my amps on the noise goes away, so I know it is not my amps. I have even gone so far as to run everything off of a battery backup with nothing connected to wall power and I still get the noise.

Thanks for your help.

XLR's have higher gain than RCA's. (Has to do with how common mode rejection occurs.) Plus, early in the AV7005 thread, it was commonly noted that XLR's were noisier in general than RCAs. So you could try RCAs and go from there.

XLR's are sometimes only better if you have a large external source of noise. Otherwise, RCAs can be quieter.

Steven.

Late February for the MM8077? That's odd as Amazon is showing they have one left in stock

Try one connection at a time with the amp before you rule out a wire or amp connection.

If you have a cable set top box, disconnect it completely. In my case that was usually the cause of ground loop hum/noise.

You can buy ground loop isolators if that is the source.

Not to be confused with -12VDC, or pulsed 12V DC, etc, Constant 12V simply means it stays on, that assumes it is +12V:)

Thanks for your help.

I had this problem once and it was a grounding issue. If I recall correctly I had some components grounded to other outlets. Connecting certain components to the same outlet helped. YMMV

I hope "soundstage comparisons" won't be made, period. Gulp.

I was just doing this for effect. But you are wrong about the Parasound. It has an Antec Component Cooler on top not to mention an eight mini fan block on its back end. Been like that for a year now with numerous Receivers on top and never once and a single issue. And that is after many long football marathons and movie nights. I also have Antec Component Coolers on top whichever Receiver/pre-pro is running. smile.gif

What kind of component coolers do you use?

Why?
post #862 of 11290
Crap, I forgot an anecdotal, subjective, and scientifically irreconcilable account contrasting such things between AVRs still holds veracity for a percentage.

Opps, carry on then. I for one think the Marantz will sound much more open, unveiled, and steer effects with a sliver of increased detail and velocity than the Denon. Totally worth the additional cost on those merits alone, but copper casing and a nuanced, but still markedly superior fit and finish will be icing on the proverbial cake.

oh, and it (the marantz) will have a less muddled midrange once it's hooked up to the Parasound with xlrs. Lowered noise floor, too.

It will all be indubitable. Or just an opinion that will still carry substantial weight, because that's what someone heard.

Go figure.

My point is that if I were going to compare any sound quality differences of two high-end units I would not stack them inches apart This is not about cooling, noise isolation can play a big role at times which is important in high-end gear and testing units sandwiched on fans and amps is not a good baseline. Why not put a cable box on top as well with all it's noisy RF or a Sat box on top of a power conditioner? Trying to see the small but sometimes important differences in components is not always possible even the same room but I would at least have some basic base-line steps in the evaluation to isolate any potential installation compromises:)

The copper (plated) components can be silly, there are more effective ways to do noise isolation in the design.

The Satellite box did cause a ground loop hum so I had the tech come out and he disconnected the green ground wire on their hardware outside of my house. That fixed that problem, but I still have the noise. Thanks for the heads up though.

betcha a large amount that if you measured the output it wouldn't make a dimes worth of difference.... smile.gif

"noise isolation" is an even bigger boogeyman for audiophiles than (dare i say it out loud? ) jitter...

your "concerns" are unwarranted... but then again, your expectations are as well...

Yes I did that and it did solve the biggest of ground loop hum issues that I had with the plasma tv. I initially had two ground loop hums and a noise issue. I have solved both ground loop issues, but I still have the noise issue. Thanks for the advice.

Hello, does anyone know if this pre-amp has any flexibility with the Pre-out terminals? I looked in the owners manual and didn't see a way to assign the audio outputs for say bi-amping. Thank you.
