Exclusive Denon AVR-3805 First Look!

[tlparker]

I've seen the 3805 price drop and want to know if I can use two identical AVR 3805 units as master & slave such that the second unit is merely acting as a power amp so that I can tri-amp 4 speakers and bi amp the 5th center channel.

It is my guess that this is not reliably possible; much less wife friendly.

Please replay if you have a strong understanding of the feasibility of this scenario.

Thanks

Hmm... what would happen if you took alll the pre-outs and matched 'em up with the "future ins" (meant for SACD or some other as-then-not-defined decoder)? Then hooked up all your inputs to the first one (and all your video outs), seems like at that point you could horizontally or vertically bi-amp every speaker pair.... wow... this IS something to think about, unless I'm off my rocker again... or, you'd think it'd never be cheaper than just buying a 5.1 or 7.1 amp (but then you can't bi-amp with it, so you'd have to buy bigger).

Does the Denon 3805 Receiver has a 12VDC trigger buit-in?

The reason I am asking is because my Panamax 5410 has an input trigger which will sense the power signal to initiate the startup or shutdown sequence without using the button on the front panel.

Thanks

Does that power strip using one A/C to detect and control the others, or does it use a 12V trigger input? I've been looking all over for an A/C switch/conditioner that I could plug a couple of mono-bloc amps into and turn them on/off via a 12V trigger to the A/C strip they were plugged into since they don't have a 12V trigger of their own. OMG! I just looked up the 5410 and sure enough, it'll do it, for 5-700 dollars!!! Anyone know of a simpler A/C outlet strip or switch that's controlled by a regular component 12V trigger?

My Sub in Not Working???

Can someone help me figure this out? I am New to the 3805, but I have my Powered Sub hooked up to the Sub Input on the Receiver, and Yes in the Menu where is ask about the Sub Yes or No.
Can someone help me? Thanks Everyone! Bobby

Sub input??? I hope you mean the sub output. Check the level of the sub in the channel adjustment and make sure it's not at neg 10. Have you used the room auto EQ with the mic? Sometimes you can get wierd readings and it will set the channel levels wacky, but usually higher not lower. More details are always helpful, you didn't give much to go on.

 

[bobby9858]

Yes, sorry Sub Output . How do I get to the channel adjustment to check the Sub Level? No I didn't use the Room EQ with the setup mic. (I don't have a mic.), Plus I heard it didn't do a very good job.
My Sub is a Pretty Big Sub with Lots of Bass, so I don't know what the problem is?
I did notice if I turned Everything on the Sub to as High as it would go, And turned the Volume up Alot on the 3805 I could faintly hear a little out of the Sub, but very little.
Sorry I haven't given you very much to go on, But this is the First A/V Denon Receiver I have owned, so I don't know alot about how it works.
Hope someone can help me with this problem. Thanks Bobby

Bobby - welcome to the forum.

You need to go through that manual and learn how to use the onscreen menu on your tv. (Take a yellow rca cable and connect it from the Denon's yellow "monitor out" to your tv's free A/V yellow in) Once you figure out the onscreen menu, the receiver is a joy to work with.

First off, if you know how, set all your speakers to small. Set your crossover on the Denon to 80Hz. Set the sub and speakers to LFE, and not LFE + Main. Then set the dB level on the sub to +10 or +15 dB. If that doesn't give you enough control/bass with the sub, nothing will.

Have you played with the graphic eq for each channel yet on the Denon?

Thanks I will hook the video up if it is that easy.
Yes, I can manage to get to where I can set all the Speakers to small, but I shouldn't have to do that should I?
The Crossover is set to 40Hz right now, but I tried setting it from 80 to 200Hz, but it helped Very Little if at all even at 200Hz.
Also right now the Sub is on LFE + Main, But I tried it on just LFE with No Luck (What is the difference between LFE, and LFE + Main).
When you say set the db level on the Sub to +10 or +15, is that where there are only 3 to pick from, and them being +15, +10, +5? If so, it is already on +15.
When you talk about the Graphic EQ for each channel, I am not sure if I have been there or not, can you tell me how to get there, and I will check.

Thanks Bobby

Is you're sub active or passive? The above statement sounds like you may have the receivers line level outputs hooked up to a passive sub and since line level is low voltage a passive sub will hardly make a sound. if your sub is active with a built in amp then disregard what I just said

cheers

Thanks for your response.
My Sub has a Built In Amp. It is a 130 Watt Sub, that plugs into AC.
Just yesterday (Before I got the 3850), it was on my Harman Kardon Receiver and it would blast me out of the house if I turned it up even halfway, and now I can hardly even tell its on at all with the 3805? I don't understand what is wrong?

Thanks Bobby

 

[AVRat]

See pg. 34 of the manual to set & test channel levels. Please, please, please, read the manual to understand the capabilities of the receiver.

 

[bobby9858]

Hello AVRat

I have read through the manual, and have tried different setting on the channel levels with no luck.
I am beginning to think there is a problem with the Receiver. Does anyone else have any ideals? Thanks Everyone.

 

[bobby9858]

Please does anyone have anymore ideals? It seems like maybe the Receiver is at fault, do any of you agree or am I missing something here?
I just bought this 3805 used, and the seller said Everything was perfect when he shipped it??? I am not sure if he is telling the truth now :-(
I had a Electronic Store guy come over, and he said that it looked like the Sub Woofer Line Output, Center Line Output, R & L Front Line Output, and Both Surround Line Outputs were not working? I don't understand this
It has to be the Receiver, doesn't it?

One other problem I have is with the Remote, it keeps Freezing up on me, has anyone had this same issue? Thanks Everyone!

Take the receiver to a Denon Authorized Repairer and have them check the unit for faults, it sounds like there is a problem other than setup issues.

cheers

I don't know what to tell you about the sub out, sounds like there could be a problem with the receiver as it's pretty straight forward to get the sub to work. I'd start with the seller and ask him what's up. As far as the remote goes if it has the black face then it's bad and Denon should replace it regardless of whether or not it's still under warranty. If it's a blue face remote and it still freezes up then contact Denon and they may replace it for you. The remote is a POS either way and I only used mine to program my MX 500 universal remote and it's been sitting in my closet ever since.

Settings

Howdy,

Can I assume that if I just looked at and didn’t changed any of the settings programmed into the AV Receiver that they well remain as set and not change back to an earlier default settings? My assumption is that nothing will have changed, but I’d like to hear some confirmation to that conclusion.

Thanks
Bart

The settings will not go back to their defaults because you looked at them.

Input trim?

On my Yamaha DSP-A3090 I can adjust the volume (trim) of each input (source) so when you switch sources (say from watching a DVD to cable box) the volume stays relatively the same. Anyway to do this on the 3805? I scoured the manual last night and went through all the set-up menus but didn't find anything.

Any info is appreciated. Thanks.

 

[Bryce_H]

So anybody got any insoght into the previous question?!?

 

[avliner]

Hi Bryce,

no, the 3805 doesn'tahave the trim setting facility (the 3806 does have it though).

Cheers / Avliner.
