Using multichannel.

[pewternhrata]

Just because I'm always looking to learn more or clarify random questions. Denon 2900 with multi out. If I were to run 3 cables, front left/right and sub to the outlaw I would bypass any kind of processing performed by the outlaw, correct? I have no plans to do this just in theory it would work? I dont see any 'performance' gains over digital or rca, unless I was playing sacd or dvd audio.

Many receivers' analog multi-ch inputs will bypass further processing, here's what the 1050 manual says about using such:
5.1-Channel External Processor Connection.
In addition to the standard stereo audio inputs, the
1050 has a six-channel analog input designed to
accept the output from a product with a built-in
surround decoder. Since the 1050 does an
excellent job of decoding all current A/V surround
formats, this input is intended primarily as a means
of accommodating emerging multichannel music
formats, such as DVD-Audio and Super Audio CD
(SACD). It can also be used to accept the
multichannel output from a DVD player or HDTV
converter that has built-in 5.1-channel Dolby Digital
or DTS decoding. However, you will get better
results making a digital connection from the player
and allowing the 1050 to handle Dolby Digital and
DTS decoding internally. For those who wish to use
the 5.1 channel input as a “CD direct” input, simply
connect the left and right outputs of the source
device to the left and right jacks of the six-channel
analog input. This allows one to bypass the 1050’s
DSP modes with the result that the sound signals
are affected only by the pre-amp and volume
controls
If you use this multichannel input, note that in
all modes, except 6.1, it bypasses the 1050's bass
management and crossovers. This makes it a good
option for use with the analog outputs of a CD
player or phono pre-amp where you wish to listen to
the source directly.

I did see that in the manual.
In order for a sub to play, that would have to be connected as well, correct?

You'd also need to make sure there is content for the sub to play (i.e. .1/LFE content, or use the bass management in the Denon to create it).

In addition to what HD mentioned already, I would add that while it bypasses the AVR's DSP decoding, it may not, in fact unlikely to bypass the ADC/DAC. Even in the old days, such as my 3805, it would only bypass the digital circuitry in pure direct with analog input selected (presumably same deal with the MCH analog inputs) and subwoofer level set to mute/zero. (Edit: not mute/zero, it should be set to "OFF")

Would the adc/dac conversion be important/audible, though? Level set to zero (instead of a plus or minus dB value) and mute aren't quite the same thing to my mind (mute would be setting subwoofer to off?). Then again I've not fooled with multi-ch analog inputs in a long time....actually never, now that I think about it, just 2ch.

Good catch, thanks! I meant to say "OFF" and to do that you have to go below -12 that is otherwise the minimum.

According to the operating instructions for the AVR-3805

I used the 3805 as an example only, to show that even with Pure Direct and Analog selected, there may still be some digital processing. The newer models don't even have the analog selection and I am not sure exactly what Pure Direct/Direct turns off or disable.

Whether ADC/DAC would have audible impacts or not is going to be debatable and a subjective thing. I don't believe the effects would be audible, but certainly visible.

I'm gonna sit back and wait for the debates lol, I'll apologize in advance.
But seriously thanks for the info, I've never played around with it too much, doubt I ever will but was getting curious

@PENG in any case our Denons don't mean a lot as to what the Outlaw may or may not do, and my 3808 and 4520 don't include a lot of details in the manual as to processing specifics. Might be time to ask Outlaw some questions. Or just connect it digitally and have less headache

I agree, you never know. Just because my very old Denon is an apple doesn't mean Outlaw or even a new Denon is not an orange. Just can't assume anything based on one of more examples.
