Marantz AV7005 - Page 267

just checked again the noise from the sub-woofer, it's there...
basically white noise that i can hear it when i'm around -3db and up.

i tried different cable , routed the cable different way , disconnected input after input to the 7005 ..didnt change a thing.

anyone else noticed this ? basically when i'm not playing anything and when it's at -3db or 0 and above.
it's not end of the world , but it can get annoying .

one more thing i tried : connected the power of the sub to the same outlet as the rest of my components
and connecting it to a different outlet , same.

That you can hear from your seated position? or only if you walk over to your sub and hold your ear up close to it?

I've been a theater enthusiast for awhile now, but this is my first venture into networking anything. I'm not gonna lie... I had to google WD MyBook to see what you were talking about. Looks cool! I will surely be reading more about those types of devices.

Got mine yesterday. It is sitting in the rack and looks beautiful. Will be hooking it up tomorrow. Need to fine me a tripod for the Audyssey mic today. I lost mine in the divorce... !!

I was also reading a review and the guy said that he was able to change the input names very easily through his laptop. I was looking through the manual a little bit last night but didn't come across anything that pertained to this. Anyone know how this is done?

I have an Oppo BDP-83, Toshiba HD-XA2 (yes I still have some HD-DVD's that I haven't replaced with Blu-Ray yet and the Toshiba still works wonderfully), which will be hooked up via HDMI

A Roku box via HDMI also.

A samsung DVD/VCR (I mostly use this for transferring video from VCR to DVD for family and friends) will be using component for video and coaxial for audio

A Sonos Connect that I will be hooking up via coaxial

My DirecTV DVR will be hooked directly to my TV via HDMI and to the AV7005 via optical.

I would like to be able to name all the inputs if possible

Thanks in advance

Thanks, must have missed it... probably shouldn't have been watching the Bruins game at the same time...

I can hear it from my seated position.
I noticed yesterday when I turn on the PS3 is louder.
And the noise is kind of random , it's not a hum , almost like digital traffic ...maybe I should try removing the Ethernet/router next.

So the sub on different outlet , the RCA to it routed away from everything , the ps3 is on its own outlet and the av7005 on a third different outlet

Go figure ...

I switched all the XLRs to RCAs and the speakers hum is very low (like with the 3312).
I need to monitor that , and see if it's even consistent .

I thought XLR should improve things not make them worse . Not sure what's the brand on them but they sure look nice (came with the seller of the Rotel 1095).

Should I get power conditioner ? (any recommendations ?) can that actually help ?

I'm really trying to make this work ,
don't want to Return this unit .

What brand of RCA or XLR wires will in no way alter the noise level, assuming they are properly shielded to begin with (which is 99.9% most likely, even if they are very inexpensive).

You could reduce this noise problem you are having by pushing the sub further away from your listening position. As you know, more distant things sound quieter to our ears. Try a more distant location. This will necessitate a new auto microphone calibration run which will find a need to increase the sub out level.

Also, is you need even more noise reduction, do this:

Generally to minimize noise and achieve the best possible signal to noise ratio for a series of devices, you want each one to pump out the highest level it is capable of, without clipping/distorting and without overloading the input section of the next device in the chain.This is called optimizing the system's "gain structure".

In your case this means turning down the gain knob (level) of your sub and cranking up the sub level out of the AV7005. Try to achieve an auto mic level of , OMG I can't believe I'm about to write this but I really do mean it, "+11 dB" ! This is instead of "+12 dB" because at that setting you don't know for sure if the AV7005 is simply using a shorthand way of saying "I'm giving her all she's got, Captain! [yet more is actually needed, sorry]"

Danny,

Why do you make a point of mentioning that each piece of equipment is on a separate outlet?

Using different wall outlets a good way to introduce hum into your sound system unless all of the outlets are connected to the same phase of power coming into your home.

(I use industrial Tripp Lite IsoBar power strips which include both transient protection and high-frequency filters to provide some electrical noise isolation between my audio equipment. Some people find that method, umm, distasteful. The IsoBars are all plugged into one power-strip which is plugged into a single wall outlet. The one item plugged into a separate outlet is the projector, but that's just because it's on the other side of the room.)

Anybody use the HDMI on the front panel from a laptop to play a movie or anything? I can't seem to get my laptop to recognize the AV7005. I've used the Input Assign to enable HDMI 6 to the Aux 1 input, and tried setting the Input Mode to HDMI rather than Auto, but still no luck.

My laptop supports HDMI audio. If I bypass the AV7005, the TV will play both sound and video once the laptop recognizes the TV. I can't force a laptop signal, it has to recognize the attached device.

Any help much appreciated.

Norm

I do that sometimes. Many laptops are incapable of simultaneous HDMI and main built-in LCD screen output. Do you know the toggle mechanism on yours which allows you to select which output is active? Perhaps you errantly have it on "LCD"? On mine there's a mode called "both", but it doesn't really work, or at least not in the resolutions I use. I have to set it to HDMI only.

I would try going straight to the monitor first to establish your HDMI out is up and running on the laptop, and then without powering down, yank that cord out and attempt to go through the AV7005 first, instead. Good luck.

well i was probably not clear enough , i started with everything connected to the same outlet . putting them on different outlets was just part of trying different things and maybe isolating the issue.
yes i'm aware of the issue i may introduce by doing so. but it was there even before that.

the knob on the Paradigm DSP-3200 was in the middle.
after running audyssey i got the level on the sub at -5.5db and the distance was way off . maybe 22ft while it's actually in line with the speakers at 10ft.
not sure why it did this (same thing happen here when i run the Denon 3312).

So i reduced the power on the sub on its knob to maybe 25%.
and increased the +9db. i should probably re run audyssey .

so yeah that "pushed" the problem to much higher volumes : now when im at +1.5db i hear intermediate white noise (from my seating position) from +3db and above it's constant.
i tried disconnecting everything from the AV7005 , shut down my internet . it still there.

So i have few questions now :

1) is this a good solution ? i mean isnt that just "hiding" a problem ? why didnt i have that issue with the Denon or the Pioneer 1121 ?

2) am i'm too picky about this ? or would you live with that and say that's reasonable ?

3) Whats the reason for audyssey to assign such a distance to my sub ?

when i run it , i tried to follow the audyssey threads instruction and followed the 8 points location. Had the mic on a camera tripod as well pointing up.


by the way , going to RCA between the 7005 and my Rotel solved the humm noise completely
thanks

The DSP-3200 requires time to process audio, and that delay makes it appear to the Audyssey like it is further away than it actually sits. The extra 12' means roughly 12 ms internal latency in the DSP. Not unusual at all.

So should I leave it as is ? Or manually fix the distance ?

Leave it. To both your ears and the mic it acts as if it really were that distance away.


Yes it is a good solution. Everything has noise. Some louder than others.

Another way to reduce the noise even further, assuming it is of a high frequency nature, is to place the sub behind a large, stuffed chair or couch. This will "muffle" it. As we all know, a pillow in front of a speaker will reduce its output, but not in the low frequencies, which is all we care about with regard to subs. You will reduce the perceived noise but the bass part still works fine.

Refer to the Audyssey FAQ linked in my sig.

Danny,

Unfortunately, the intermittent noise really could be due to you having received a defective unit (e.g. a loose internal connection), especially since you don't hear it with the Denon. I'd suggest contacting the place that sold it to you to find out if you could get a replacement.

Is it possible that you have your Sonos device positioned anywhere near your sub? Mine was, and it caused a hum just as you describe. As soon as I move Sonos the hum dissappeared.

MZ - tried all that, no luck. Laptop won't recognize the AV7005 as a video display but if i go direct to the TV it will see it. The laptop has to see/recognize a connected device before allowing it to be selected, I can't force it or select it as a display until then. When active on the TV and pulling the plug, the handshake is lost and laptop reverts to it's own display.

Was more wondering if I've missed something in the AV settings? Otherwise looks like I've got a handshake issue I can't resolve specific to the laptop (Dell Studio 1735).

Norm

Well that's a bummer. There are no settings on the AV7005 (that I am aware of) which might help.

The only other thing I might suggest is to try lower resolutions (I assume you aren't attempting anything higher than 1080p, but you might try even lower, like 720p and 480i/p, at least to initially make a handshake connection. Hopefully once established you can then can go back up to 1080).

Also the power on sequence might matter. You have a laptop (L), the AVR7005 switcher box (S), and finally the monitor (M), so you have to try all 6 permutations: LSM, LMS, SML, SLM, MSL, and MLS. Some devices are very sensitive to turn on sequence, others aren't, but at least trying this out is free. You need to turn on each device and wait for it to stabilize before then moving to the next device to turn on, and wait to stabilize.

Good luck. I'm out of any other ideas.

Sometimes handshake problems can be corrected by firmware updates.
Check that your AVR's firmware is current. Also verify that both your laptop's BIOS and its graphics driver are up to date.

Thanks folks, firmware and drivers are all current, tried everything but the power sequencing as that's going to take forever for the slow laptop. I'll try that over time.

Norm

no , i dont even know what that is.
i turned off everything near the Marantz, and whats more important
its the same identical (everything) where a Pioneer 1121 and Denon3312 where without that problem.

Try inserting an HDMI switch between the AVR and the TV.

I've been ogling this machine for some time. I can get the av7005 and matching mm7055 amplifier for around 2k, but it's a limited offer - just this weekend. Basically on the fence now, should I or shouldn't I.

I'm driving my front 3 pio ex speakers with a sr6003 currently and wondering if this would be a significant enough of an upgrade. I'm pretty sure it is and I believe the av7005 offers anything I'd look for, but meanwhile I'm also thinking D&M will probably release info on 2013 models soon and 'what if' there's something in there that's even better.. I hear this xt32 thing is the latest buzz word, now I feel like I'd be missing out if I didn't get anything with that. The Denon 4311 still retails for 1800 where I live; no sweet deals like what can be found in the US.

Of course they will release something new .... So why not wait for the 2015 model ? I'm sure it will be even better .

I would have wait if I knew its coming out REALLY soon . But you talking at least a year here . And I bet you wont get a deal like you mentioned anyways .

Set up my unit on Saturday and had to run Audyssey twice.

The first time it set my sub at 21.5 feet. My couch is probably about 18-24 inches away from the sub so when I ran it a second time I slid the couch back so the front of the sub wasn't being blocked and it got the distance right.

When it was all set up I put in the train crash scene in Super-8...WOW!!! Sounded really really good, don't remember it sounding that good with the Anthem. It seemed to be a more enveloping sound and the sub sounded real good too. So I think Audyssey definitely helped.

Music wise I had some people over Saturday night and we watched some Concert BluRays...Jeff Beck, Heaven & Hell, Steve Vai, everyone seemed to agree that it seemed to sound a lot cleaner and detailed.

I haven't had a chance to listen to two channel yet, I wanted to see how the DTS Master-HD on some of my music blu-rays sounded.

So overall I am extremely happy so far. Though I do miss being able to change bass and treble, and speaker levels on the fly with my Anthem remote, not a biggie as it does sound really good.

I know the Marantz can adjust bass and treble when the Dynamic control is off, I was just able to to that directly via the Anthem Remote along with center channel, fronts, rears and sub volumes. I seem to always want to tweak things as I listen.

Also is there a way that the sound will go through the unit in stand-by through it's HDMI inputs. I have a Roku box for streaming and really don't want to turn the 7005 on every time I want to stream an old TV show or B&W horror movie or something that doesn't require surround sound.

My unit is dead quiet also, no hiss through my speakers at all.

Happy AV7005 owner

Well, I reported this to Marantz. The one question they asked was whether the same symptom occurred with Pandora and Internet radio. I told them it does not. I only get the lockup after running AirPlay. Their response was that the problem must be in my router and I should contact my ISP.

sigh.

not un-common to get odd measurment of sub, Audyssey(mic) is sensing, or interpreting, output from low-level, low frequency, source.


this is good! What amp are you using with your AV7005?
