Curious Posted April 2, 2007 Posted April 2, 2007 Ok, so I very excitedly reconnected my AVC-A1D and instead of running my second pair of surround speakers out of the same surround channels as my 1st set of surround speakers, I connected them to the effects pre-out (via some amplification of course)...sadly these channels appear to emit nothing but a hum from the speakers Have tried them in 5 channel mode (no real surprise that as 6th and 7th channels there was no music forthcoming) but also there is nothing in THX, DD and DTS mode So, what do they do? and how is some sort of experience (perhaps distantly related to sound) meant to be enjoyed from them Interested in any opinions relating to effects channels (and like a good little Forum dweller I will re-read my user manual for clues ) Cheers, Curious

I may have to resort to using the surround pre-outs for both sets of speakers like I used to, but this creates a different problem as I am Bi-Amping all speakers now and that means putting a splitter on a splitter for the surround channels Anyhoo, thanks for the tip Cheers, Curious
Daleos Posted April 24, 2007 Posted April 24, 2007 Curious, I am new to this forum. But a google search on M&K subwoofers has lead me to you!! (Comments you posted last September about your x2 MX-350's and the MX-5000). I am based in Melbourne (South East suburbs). Are you interested in selling one of your subs??... or know anyone that maybe?? Reading your posts, you obviously love them and so do I!!!! Also, I have found two guys selling their S-150 THX Ultra system's and wanted to hear your thoughts. Cheers, Daleos

I would enquire of denon if you can upgrade to 7.1 software [ rs 232 port?] ;then your presence outputs will drive your separate 2 ch amp for full thx surround

I was aware that it is 5.1, but naively figured that because there are pre-outs (labelled effect) below the Surround pre-outs that they must create a separate effect channel (although none of the modes seem to enable them - DTS DD THX all failed to create a sound) I have not yet located my manual since moving house several times, so any answers from Denon remain out of reach for now. I wonder if Denon would include extra surround pre-outs without the technology being present in the AVR to run them I'll send off an e-mail to Denon, failing any illumination from the manufacturer I wonder if there are any experts on the AVC-A1D out there? (I feel a new thread coming on) Cheers, Curious
Curious Posted April 24, 2007 Author Posted April 24, 2007 Hi curious :ph34r: Are these effects channels mounted higher above the front mains either side of the screen???If so............! Short answer is 'no', but where I have them mounted (directly rear of the room) is not perhaps where Denon would have me put them I didn't think they were front effects based on their pre-out location below the Surround pre-outs...could easily be wrong on that...need to hunt further for the trusty manual Cheers, Curious

(I feel a new thread coming on) Curious; I recall Harman Kardon released similar amps where you had to add a extra 2 ch power amp for back surrounds ;even when thx upgraded to 7.1 and dd ex first happened.I found a picture of the back panel [no rs232 port unfortunately] but If you buy a hd player with 7.1 analog output[the pannybdmp10] ;your amp can handle that through its 8 ch mutichannel input. This shows good insight into future proofing at the time At least you can use the pre out back surrounds this way If denon dont come good

Another look at the back panel of my unit reveals 6 channel ext in as well as (wait for it) 8 channel ext in...woo hoo!!! It would appear that all I need to do is to purchase my future HD-DVD player as a 7.1 pre-out model and I can use the effects channel on the controller vis a separate 2 channel amp Thanks for clearing up the mystery CWT...youdaman Cheers, Curious
