hawke : It's slated to arrive here next week - I'll keep you all posted and I'll be sure to tear into it as soon as possible.

it's been about 2 1/2 weeks since the last post. any news on the review unit (or review content)?
thanks.

Correct me if Im wrong ,but we we all love the champagne gold finsh-right? and were a little 'miffed' that  the 3805 is available in Black (no thanks), or silver..
Go to www.denon.com, japan,  click top left button on the home page ,
behold the avc 3870 the Japanese version of the 3805
In this finish it is an ideal aesthetic match for dvd A11 (5900)
Perhaps the boys at Denon will let us have some when they have had thier fill..

ewww...not me.
i really dislike the champagne gold finish. if i pick up the 3805 i'll probably end up with black. i wish the silver was a bit darker...more gunmetal.

Truestorys,
did you check the 2200 config and set it to multhichannel?

deno just sent 4000 model 3805 out a week ago arrival 1 3 weeks depending on location

I just went to Tweeter here in Illinois.  They had the 3805 on display.  Has anyone seen the remote?  I am not impressed with it.  The picture online is deceiving.  The "touch screen" or what I thought was a touch screen is really just a pad.  

Any opinions?  I was also hoping the price would be lower.  I can get it 10% ceaper at Crutchfield plus save on shipping and taxes.  I am not real comfortable with shipping such an expensive item.  I mean no harm, but I have seen what can happed to items shipped via UPS or FedEx.

Hi, new member here, I found this site while looking for other information - after I placed an order for the 3805. I think I wish I had seen this site before buying my Denon DVD-2200 (after seeing Gene's comments on it). But the reason I am writing is that I took delivery on my new AVR-3805 on 4/2/2004 in black (I thought it looked classier than the silver, and the ligher color really shows the cut line for the swing down front panel more making it look less "of a piece&quot

. I spent most of my weekend physically installing it in a new rack. It took extra time because my older Sony digital-ready receiver didn't have all the connections this has so it wasn't a simple of matter of unhook from here connect to there. I wish I could report more at this point, but can not yet. Except to say that when I turned it on it was set to "Tuner" and all it had was static so I tuned to a classical station just to eliminate the static and was amazed at the sound! I wasn't trying to do an A / B listening test, and I believe that speakers make more of a difference in sound than electronics, but I wasn't prepared for the hearing the orchestra over 3805 with my existing speakers and having it sound so obviously better!

Still trying to understand the owner's manual, the remote - it isn't programmable like my Pronto, but not a static button unit either.

I have a lot of catching up to do here.

Thanks,

Marie

the primary difference is the presence of a 'denon link' on the 3805 . this allows for the digial transfer of cd, dvda, sacd, from the dvd a11 to the 3805.
It is the best way to clarity..
the 3805 also has a pure direct mode, again for quality sound in music mode.

Can anyone tell me if I can use a the Denon AVR-3805 to drive 4 ohm speakers such as the Axiom M80ti's?

MarieonCape · Apr 5, 2004

Elliot, the 3805's owner's manual states that speakers with an impedance of 6 - 16 ohms can be used as main or surrounds.

Thank you, Marie, for your help.

gene · Apr 6, 2004

Elliot;

I realize it can get confusing sometimes when receivers have recommended impedance ratings, but impedance doesn't tell the whole story.  What really matters is how reactive the impedance load is, and how efficient the speaker design is.  Some 8 ohm speakers are more difficult to drive than some 4 ohm speakers based on these issues.

The Axiom Audio Epic 80's are a relatively efficient speaker system.  The Denon AVR-3805 has quite an ample power supply for a receiver in this price class.

I believe others on this forum are successfully runing their Epic 80 system on receivers of lesser power capability then the AVR-3805 with great success.  

I don't believe the AVR-3805 will have any problems driving your Epic 80 system, especially if you are using a powered sub for the LFE channel.  Just keep your tone controls flat and you should be fine.

If you are in a large room, and like to really crank it up, somewhere down the road, you can always add an external two channel or multichannel amp to the system.

MarieonCape · Apr 7, 2004

My only intent was to post what Denon said in its manual in case that might be helpful to Elliot. I am not qualified to provide the kind of information and insight that Gene can. Please look at the following in a "what's worth" mode.

The specs section of the manual lists the "Power Amplifier Rated Output" as 120/ch at 8 ohms (20 Hz ~ 20 kHz with 0.05% T.H.D.), 160/ch at 6 Ohms (1 kHz with 0.7% T.H.D.).

It follows that with "Dynamic Power"
140 W x 2 ch (8/ohms)
210 W x 2 ch (4/ohms)
240 W x 2 ch (2/ohms)

Output terminals:
Front, Center, Surr. Back/Multi Zone 6 ~ 16/ohms
Surround: A or B 6 ~ 16/ohms
A + B 8 ~ 16/ohms

There is more on the subject from the manual that I've posted below in case it has value in your situtation - not to argue with Gene! I couldn't! But it seems as if Denon acknowledges that speakers of less than 6 ohms will be hooked to the receiver.

• Speakers with an impedance of from 6 to 16 ohms can be connected for use as front and center speakers.
• Speakers with an impedance of 6 to 16 ohms can be connected for use as surround speakers.
• Be careful when using two pairs of surround speakers (A + B) at the same time, since use of speakers with an impedance of less than 8 ohms will lead to damage.
• The protector circuit may be activated if the set is played for long periods of time at high volumes when speakers with an impedance lower than the specified impedance are connected.

Note on speaker impedance

• The protector circuit may be activated if the set is played for long periods of time at high volumes when speakers with an
impedance lower than the specified impedance (for example speakers with an impedance of lower than 4 ohms) are
connected. If the protector circuit is activated, the speaker output is cut off. Turn off the set’s power, wait for the set to cool
down, improve the ventilation around the set, then turn the power back on.

Maybe someone should lend these guys a receiver you then have the knowledge that if it gets the thumbs up it has been given the full test

just a thought

I have been using 4 ohm speakers (M&K 850) with my 3805 and it sounds great.

From the Denon FAQ:

CAN I USE 4 OHM LOUDSPEAKERS WITH MY DENON RECEIVER OR POWER AMPLIFIER?

Yes, you certainly can.

To understand this a bit better, first realize that all amplifiers are designed to deliver a signal into an electrical "load" or resistance presented by the loudspeaker. We measure resistance in units called "ohms" (after the German physicist Georg Simon Ohm, 1787–1854).

Conventional wisdom makes an 8 ohm loudspeaker load the most acceptable because it "protects" the amplifier from delivering too much current. A 4 ohm loudspeaker can encourage a marginally designed amplifier to deliver more current than it comfortably can.

However, you should remember that a loudspeaker’s impedance rating is a nominal or average one: A speaker rated at 8 ohms may actually vary from 5 (sometimes even less) to 20 ohms or higher, depending on the frequency at which you measure the impedance. (Don’t worry about this too much -- good speaker engineers are well aware of these variations and take them into consideration when designing products.)

In general, you’ll find that Denon products are designed to function with a wide variety of loudspeakers and have power supplies and output circuitry more than able to meet the current demands of low impedance loads.

In the rare event that very low impedances tax the amplifier, quick acting circuitry will protect it from damage. If unusual operating conditions trigger this circuitry, the word "PROTECTION" will appear on the unit’s front panel. If this happens, simply turn the unit off, wait a moment or two, and turn the unit back on again. The protection circuitry will automatically reset. If it re-engages, check your system for possible malfunctions.

Hope this helps.

I recently purchased a 3805 and am having some dificulty setting the thing up. My other yamie receiver default / auto mode does the trick for the room it is in (20x20). So this is all new territory for me.

the denon is in my basememt which is 40x40 and is an open air thearter/bar/game room. I have four basic problems.

1. how do I set up the frequency for each speaker (ex +5+4+3+2+2+3+4+5)? Should the front speaker be different from the rear? what will give me the best sound for movies.

2. there is one section during the set-up that ask for a hrz setting. It ranges from 40 - 250. What does this mean? and what is the appropriate setting for m y set-up?

3. I have 12" subs in my main speakers and have used them in the past to add additional base during movies. I set the subwoofer setting to send low signals to the sub and the fronts but the base is not anywhere near that of previous set-ups. is this related to the frequency set-up (above) or is it the receiver?  or just me?

4. what is the delay setting? what does it delay?

As it stands everything is kinda mudded. I know these r silly questions but any assistance would be great. thanks!  

MarieonCape · Apr 8, 2004

Why not use one of the new features of the 3805, the auto-speaker set up mode? Yes, I know the microphones aren't available yet but there are instructions on how to use another microphone. Personnally I plan to use this feature myself!

Do the "subs" in your main speakers have seperate inputs from the "regular" speaker inputs?

ask for a hrz setting. It ranges from 40 - 250

I believe you are refering to the subwoofer cross over frequency.

no my mains are simple tower speakers with 12" for lows. In my other set-ups (family room and bed room both 20x20) they eliminate the need for an stand alone sub. They boom pretty darn well, crisp and clean. for some reason I am not getting that from the denon.

The Hz setting i mentioned refers to the "cross-over frequency" (looked at it again last night) It is a setting for the entire sys it is not specific to one speaker. so I am sorta confused. It sounds best (I think) when set at 40 hz. Any suggestions or insight on what exactly this does?

The auto set-up needs the mic. I refuse to pay for the mic and Tweeter said the manual set-up is better. I may just go by there this week-end for some help. I just hate asking those guys for help. Sound so much like a newbie. I do have an ego u know.

thanks for the advice on using another mic. I missed that in the manual.

As for those thinking about buying the Denon, I played with it again last night and made more progress that b4. I set the highs, mids and lows a little higher and the sound got much better. I had the mids too low and that is why I was getting the muddied voices.

The sound is much better than with my yami. I love my yami but it can be a bit bright with my speakers.

JBL S312 II (fronts), JBL S-Center II or Infinity Alpha 37C (center) not sure which I like best yet, JBL S26II (rear and rear back). The Jbl studio series speakers are great for movies. absolutely wonderful!

The remote on the Denon is great. the switching from tv to dvd just by clicking one remote is awesome. I have a Mitsubishi XD300 projector to this a great set-up. I only have to have one line going to the projector. wonderful!

I think I like the yami set-up better (may be biased b/c I have had the yami for 2yrs). I may also like the auto mode better. just not sure yet. I have only had the Denon for about 10 days.

The Denon is also much warmer than the yami. great since both of my center channels are bright and need to be lowered for the best sound.

For music, the 7 channel stereo mode is nice. fills the room with clean sound. the tuner seems a bit weak. most of my channels are static. not that bad with the yami. I may need  to hook it up to my house antenna.

Overall so far, I love the Denon. I am not sure if I would have had the set-up issues with the yami vr 2400 (was about to buy this) but that just may be my learning curve.

but if anyone can enlighten me on the questions I posed in my first post I would be grateful.

Thanks
