Hi All,
I am a novice and my understanding of these things is somewhat limited so please excuse any ignorance on my part. I need some help & understanding with an issue regarding AV Receivers that offer Dolby Pro-Logic IIz & Audyssey DSX formats (especially since most that do usually offer both). Regarding the "Height" speakers, DPLIIz & DSX have two totally different criteria (except that they should both be high up close to the ceiling I believe) for the placement of these "Height" Speakers. DPLIIz clearly specifies a fixed position whereby the "Height" speakers must be placed directly above & in-line with the Main L&R speakers. DSX specifies that the "Height" speakers must be each placed at an 45° angular spread left & right from the listening position which means their positioning is variable & will likely mean that the DSX "Height" speakers will be further apart than the DPLIIz ones. To accommodate further, they also may need to be placed in the ceiling and/or at the side walls further "into" the room to achieve the positioning angle. This then also means that in most rooms, it is probably very unlikely that one will be able to use a single set of "common Height" speakers to use/interchange between the formats as you cannot have a single set of speakers at two different positions.
With that in mind, should not AV Receivers that offer both DPLIIz & DSX offer two sets of "Height" speaker channels/terminals - one dedicated for each format? That way, users can (if they wish) install two sets of dedicated "Height" speakers each correctly set up & in compliance with each format. As it is, users are given both formats but in practicality terms, they are limited to only using one since it is very unlikely that they will keep physically changing the location of the "Height" speakers or install two sets of "Height" speakers and then swap the cables at the back of the "Height" Channel terminals on the back of the receiver every-time they wish to switch between the formats to ascertain which they prefer depending on the material & content at the time. I would like to ask, is there a solution to this that I may be unaware of or is there anything I have not taken into account?
In my case, I will not be running the "Back Surrounds" as my listening position is right up against a back wall. In addition to the standard 5.1 layout, in order to run DSX "Wides", DSX "Heights" & DPLIIz "Heights" one would need a 9.1 Receiver with 2 sets of "Height" speaker terminals or a 11.1 one if not more. Surely, the manufacturers all know this & I am bemused why they would offer features which then cannot be used fully and/or omit something that is so glaringly obvious like enough connections for those features - why offer features that one cannot fully or ideally use or utilise - especially on somewhat expensive items as many of these AV Receivers are? I want to run "Wide" Speakers For DSX, and both "Height" speakers for DSX & DPLIIz - what do I do?
Also & just as importantly, can anyone fully confirm for me if it is possible to run DSX "Wides" & DPLIIz "Heights" at the same time on on receivers that offer a choice of DSX "Wides" OR "Heights" only but then also offers DPLIIz? By the way, sorry to be a dunce on these matters!
Many Thanks,
Bazzy!
