I use my sub for music and adjust the cut off at 40hz instead of the recommended 80hz for the sub. That way, I get more bass from my towers. I enjoy Pure Direct with the sub, along with 7 channel stereo to mix it up. I have the new 3805 and the separation is amazing. I had to canter my towers in a few degrees for optimal imaging. Made a huge difference.

That's very clever, but it doesn't qualify as 'direct' in my mind. The term 'direct' as used by every other receiver brand means direct to the amplifiers without processing the signal in any way.

If it doesn't convert to digital so it can do bass management and filter the signal to send only the frequencies below the crossover to the sub, then it must have a fixed value analog filter or send the sub a full range signal and rely on the sub's crossover (which won't be enabled in most cases if you setup the receiver correctly for non-direct modes). I'd be interested to know exactly how they do this if you have any information on it.
Well no, the SW output wouldn't be considered Direct as there is no SW channel with Redbook CD playback. The SW channel is created from a copy of the analog input to any stereo input on the 3805. The original signal is not touched, only the copied or parallel SW signal is manipulated. I don't remember the exact mechanics of the process.

Jeff Talmadge with Denon, USA explained it in a thread over at AVS about a yr ago I think it was. He was remarking that it was not well known as it's not documented in the manuals and/or is less than clear. It's been awhile since I read the exact text of what he said. I will try and search for it over there and re-post it here, but you might get a quicker and better response by emailing Jeff yourself. He usually responds quite quickly.

(edit) Just re-read your post, the signal is still full range untouched that is sent to the amp section for the L and R speakers, only the copied or parallel signal sent to SW pre-out is manipulated.

Well, I read through some Denon info on the 3805 and it said to connect a pair of analog cables from the 3910. So now I have 3 types of connections coming from the 3910 to the 3805 - Dlink; 5.1 analog; and 2 channel analog. Now I have sub output when listening in Pure Direct mode. But that's an awful lot of connections just for music.

Is there another way? :confused:
If you want to bolster or augment the bass in a 2 ch Redbook playback situation, and want the player to do the decoding, yes, you need all thsoe connections. If you want to have the 3805 do the decoding, then all you need is the Toslink or Coax for Redbook playback and you can still use the direct modes and have a SW output.

At 40Hz,you must have some monster towers and great surrounds.

Pure Direct
The sub's channel level must be set to "off" in order to turn off the dig circuit in the Pure Direct mode. So if your sub is working,you are not in Pure Direct mode?

Smokehead:
Are you asking a question here or stating that in Pure Direct mode you will not have sub output?

From what I understand, the only way to acheive sub output in pure direct mode is by making the 2 channel connection, at least from the 3910. I'm hoping there is another way so that I can remove some connections. That's a lot of cables back there.

Nothing spectacular with the towers - Ive set the towers and center to "large" so they are the only ones reproducing the lower end. The rest of the system is set to "small" so they do get cut off at 40Hz. The towers go down to 20Hz, and the surrounds are around 50Hz. I hate to limit them to a crossover at 80Hz, and have tried both ways, and like the tight bass from the drivers in them. Here's my setup with the 3805...

Thats what Denon says in my 2805 manual.

Lower limit 35Hz. I'd put my x over at 60 if using a sub but thats me.

when you guys use 2 channel for music does it matter if the speakers are set at large or small? or is it auto set for 2 channel. :confused:

se7en, I have the main speakers set as small with the subwoofer on in the "set up" menu, but in the direct surround parameters I have the sub turned off so that I can listen in stereo with the sub on and in direct/pure direct without the sub. I asume that if the sub is turned off in the surround parameters that all the bass is directed to the main speakers regardless of their large/small setting(I hope)
Cheers Steve M.

Direct or pure direct

Or, external when listening to SACD. My fronts (Definitve Technology BP 2000's) are full range
