Pseudo-Official 3805 Thread - Page 55

While I am not personally doing this yet, you may want to look into the Apple AirPort Express. It is a 802.11g wireless connection point that runs iTunes from your computer in another room. My understanding is that it has both stereo out and digital optical out. Anyone else have anything to say on the sound quality of the AirPort Express?

Jason:

Thanks for the reply. I auditioned the Paradigms yesterday and they sounded great - a real upgrade for me along with the 3805. I have a very small room so I am not concerned with more power (at least for now).

My biggest problem will be making space in my home theater for them, but where there's a will...

BTW my remote is constantly locking up - is it me?

Unfortunately, my remote was a newer blue background model. Fortunately my retailer swapped out another to try today; we'll see how it goes.

Apple's Airport Express is a very interesting device and works well with a Mac or Windows PC w/iTunes. Essentially it is a wireless downlink assuming the Mac or PC is using a wireless router such as d-link or linksys.. It has digital capability to handle PCM, Dolby Digital and even DTS streams, for analog quality I felt it sounded OK but the digital out is a better way to go sonically. But then one needs more audio hardware with DSP decoding capability @ the downlink location...

Do you use EQ feature on 3805? I try both with EQ and without EQ and i think without EQ , the sound is better. What is your preference?

thanks.

I use the eq set to flat.

A pretty good explanation of the Denon's equalization can be found here:

Roger,

Thanks for the detailed post. I would do exactly the same with running the long usb cable. That is exactly what I do now for the coax to the receiver from the laptop. I don't know why everything is so flat but hopefully the external sound blaster via usb will help. Then the deal with connecting stereo as well as coax making it sound better and have the bass is really confusing to me. The nx gives many other connection options as well.
I did some research yesterday and it was just announced a few days ago that sound blaster (creative) will be releasing their first external video/sound card.

I think this is going to be my purchases since it does what the nx does plus has a few sound improvements and allows video as well. I have lots of old family videos on vhs that would be nice to convert to dvd and this devise seems like it may be the easiest way to do it. It also comes with $150 worth of ulead video editing software and costs only $229 (estimated) so it seems like a good bang for the buck. It should be released next month. If I get it I'll post the results.

Jason, what do you mean "manual"? do you mean that you set eq to off?

thanks.

No, there is a manual selection that uses the settings you make yourself by using a set frequency graphic style EQ.

Hi again everybody:

Whenever I try to turn the 3805 off with my remote, the 3805 stays on and my remote locks up. As this is my second remote with the exact same problem, does anyone have an idea about what I may be doing wrong?

Thanks,
BigAL

Yeah Jason, I have a Harmony already, so I guess it's time to program it for the 3805, but as others have mentioned in this thread when you purchase a $1k product you expect everything including the remote to work.

BTW, I ordered the Studio 60's, CC170 (all I had room for by my display), ADP470s and Studio 40s (for rears) yesterday. My wife is gonna kill me!

I see...

After listening music by using analog out from denon dvd-2200, i think the sound from 3805 (using digital out) is not pure and clean anymore. May be my set up is wrong...i think i'll try using Manual mode to see if it makes any different. However, i hardly know about frequency described in manual mode. The only thing i can do right now is trial and error. Any source info about different frequency is appreciated.

thanks.

No, I don't have the room for anything larger either above or below my display. (sigh)

Maybe one day...

bump...someone here has got to know...

Have you tried the Direct or Pure Direct playback mode? That takes all the processing(other than the DAC) out of the signal path. You can still use one of the EQ modes for playback if you desire. The "off" mode for the EQ will take it out of the signal path. Experiment with the different EQ playback modes until you find one that sounds good to you. I generally use "normal" for movies and TV and let the 3805 do it's thing as I'm not that critical about audio from those sources. For audio playback I usually go with the flat setting, but if something sounds a little off I will switch between the modes to see if one sounds better than the other. You can also set up your own EQ playback response by using the manual mode and adjusting the set frequencies up or down, but in my experience those set frequencies are more often than not, really not the target frequency that needs to be adjusted. You can see this when you compare the frequency adjustments made by the parametric EQ when using the auto-setup function, the frequency points that are adjusted are generally not the same as the set frequencies used in the manual graphic EQ. An adjustable parametric EQ on the 3805 would have been a nice feature.

Okay, I'll give it a try.

First of all, is there a reason that you would run the system full bore on a regular basis? Unless you have a really HUGE room I don't see how you would need to tax the equipment that hard.

The decibel number on the screen will vary depending on the input signal level/source and for analog multi-channel input playback for SACD depending on how much adjustment you've made to output levels on the DVD/SACD player.

It's always desirable to have more power than the speaker is "rated" for as opposed to driving the amplifier at full bore as it will start to clip and that clipping can cause far more damage very quickly to the speaker than "overdriving" them with too much power. Hopefully the 3805 will go into thermal protection mode and shut down before the speaker is damaged.

Is it possible that the 3805 is over-heating? Does it have good ventilation?

As efficient as Klipsch speakers are, I find it hard to believe that it is necessary to crank the 3805 all the way up to listen at a "normal" level, say 78-85db with maybe 100-105db peaks.

My questions were more theoretical than out of necessity. I certainly wouldn't want to listen to it that high for any length of time or I would not be doing good to my ears. I just wanted to understand some of this a little better.
You are right, the ventilation was not good but even with it pulled out of the stand and on the floor it would still overheat and turn off after about 5-10 minutes (running at max volume). That is after it had been running at moderate volume for hours and was tucked away in the stand which has the next shelf about 2 inches above the top. The back is open but there are so many cords it really can't be considered open.
I am curious as to where they design speakers to be run at. If my mains are rated at 110 watts are they designed to be able to be run at that power for some time? My question is similar to engines. In an aircraft an engine is made to run at or within a couple hundred rpm of redline for 2000 hrs where a car engine run at redline wouldn't last 20.
Also, can you explain clipping? Is it heard so that I know I am not damaging the system?

It sounds like there may be a problem with the 3805. And it sounds like a heat issue. Do you have a way to measure the temp when you first start listening and then again when it shuts down?

Without being real technical, you will hear clipping as a popping or snapping distortion, and if you listen to it too long then the amp will shutdown or you may hear constant distortion coming from the speaker at almost any volume as the voice coil has been fried.

Sorry i think I was unclear. The thing only shut off when at max volume. I cranked it up after it was running for hours at moderate volume so my point was it didn't start out cold.
Anyway I just found out tonight that I must have blown my mid range woofer on my klipsch rp3 main at some point. I didnt hear anything pop or nothing when playing it cranked up and never heard it cut out. It was only running all the way up for 5 to 10 minutes but I think that either blew the voice coil or it severely weakend it somehow because I turned on the tv tonight and it was obviously not working. I switched the woofer from the other side to make sure that was the problem and indeed it was. Now I need to find a klipsch rp-3 woofer or find out if a voice coil can be replaced.

I always use Pure Direct when listening to CD and i use Flat mode for music, Normal for movies as well. The recording on CD probably blows the sound off. I will try difference CDs to see if it makes difference. I think DAC in 3805 is much better in DVD-2200 , however.

Welcome to the real world of what damage a amplifier can do to a speaker when it's pushed to the point of clipping!

BTW.... It can only takes a few seconds or less, to damage a driver when a amp is clipping severely. It don't need nowhere near a few minutes to do the damage.

Question on Volume - My 3805 I thought went from -80 DB to + 15 I think.
I just tryed to crank some tunes & it maxed out at - 7 ?
Did I mess up some setting ?

I've only done this to mine once, and it was running at -5 for about 20 minutes, then I moved it to 0 db... it shut off after that ^^

But considering I listen to music at -35 to -25 and that's loud enough in my room
