We have a Denon 1912 and monster speakers which we connect…

Hello, I'm Nathan and I will be assisting you today. Please remember to rate/accept my answer when we have finished. Thank you.

Hi there, sorry to hear your'e having trouble,

This combination of devices isn't really compatible,

the cinemate is meant to be a standalone device,

it is intended to serve as both a receiver/amplifier as well as the speakers

presumably most of your devices are digital (cable/satellite box, dvd, game, etc) and using hdmi connections, which the bose does not support

the idea with the bose is that you hook all your devices directly to the tv, preferably via hdmi, then a single optical/coax cable out of the tv (digital audio out port) to the bose

The optical connection on the denon is an input (to the denon) only,

it has no mechanism for outputting digital audio, so it really can't interface well with the bose system

You are really getting no benefit from using the bose system with the denon, they are both serving the same purpose,

you'd be better off putting the bose to use in another room or with another tv, and enjoying it as an independent system, and use the denon by itself

Not through the denon, no

you would need some added equipment

my suggestion would be an AppleTv,

which you can use for other functions as well (internet radio, netflix, other apps, etc)

you can stream airplay to the appletv via wifi, and the atv can output optical to the bose, hdmi to the tv, etc

Well, it depends how you hook things up, really

But yes, you would be able to

I would hook the appletv up to the denon via hdmi

and also to the bose via optical

that will let you get appletv sound through either one (basically, whichever is powered on), as well as pass video to the tv if you want to use the atv for other things like netflix

If you want video to the tv, yes

Really you don't have to go through the denon, unless you wanted to have the appletv content through the denon speakers

if you only ever want it through the bose, you can do just optical to the bose

and if you want sound through the bose for watching appletv content inside, you can hook hdmi directly to the sharp from the atv

either way would be fine

Yes, it would

sorry to cause confusion. If that is all you want, then you can connect the atv to the bose via optical, and that is all that is really needed

You would still want to hook atv to the sharp via hdmi though, because you'll have to go through some initial setup steps that require a monitor, adjusting menu settings, etc

The bose has no hdmi ports

it will only work via optical/coax (or the old analog connections)

the purpose of the hdmi (from bose to sharp) is to see the appletv setup menu and video

*sorry, I meant from appletv to sharp

and the purpose of the optical (from atv to bose) is for the audio (streaming ipad)

The sharp does not interface with the bose via the tv

what I was suggesting is that any OTHER sources that you want to play sound through the bose (like dvd, cable/satellite, etc) could first connect to the sharp via hdmi

with an optical out from the tv to the bose (passing sound to the bose, instead of using the tv speakers)

you'd need that in place as well to get audio through the bose from the smart apps which are built into the tv

you have 2 options,

you can connect the appletv only to the tv via hdmi (this is a minimum requirement)

and the appletv can then stream the audio to the bose, through the tv. This would require the tv to be turned on whenever you are playing from the ipad though

so if you wish to be able to have just the bose turned on, without the tv running, then you could also add an optical from atv to the bose

Does that make sense?

And yes, after you "rate" me, this live chat converts to a regular web page. You can bookmark/favorite this page, print it, etc at that point to see all of our prior conversation

Yes it does. The issue with the denon is that it will only want to output sound through the speakers attached directly to it

You're welcome.

Feel free to get back in touch if you get stuck during the setup process at all
