Subwoofer Cross Over and DTS HD Settings please.

[chavo]

Hi. i have a couple of questions, to begin with my set up.
Onkyo 607 Amp
Tannoy SFX sides, Rear and Sub
Cambridge Audio S70 fronts
Cambridge Audio S50 Center.

1. my Tannoy SFX 5.1 Sub has a couple of settings on the back. it has a L/R Jack input and it has a pair of speaker clips (the screw types) my Amp has a purple Sub out Jack. i use a standard Phono (yellow) cable about 5ft long in to the L jack in on my sub. this is the only connected cable to the amp. The speaker has a Volume control and a Crossover nob. I read the Crossover thread and understand the principles but that was aiming at the settings in the amp and not the settings on the actual SUB.

2. When i play a DTS HD Master Blu Ray the amp switches to DTS HD MASTER automatically. this from my understanding is a 5.1 format. i have 7.1.
If i switch my amp to Dolby Digital EX does this mean that i have turned the DTS HD MASTER OFF?? what about if ui switch to NEO:6? basically i want DTS HD MASTER in a 7.1 format... is that possible?

3. My front speakers are the cambridge audio S70. They currently have a bridge linking the 2 terminals and i hook them up via 1 cable to the front L/R respectivly. i have the ability to should i run an individual cable to the speakers, would it make any difference? i understand that bi amping is when you use a different amp (2 amps in total) and i do not want to do this. am i best leaving them bridged or should i wire them manually? as i already run a 7.1 which outputs would i be best wiring them to?

1. The subwoofer crossover should be set to the maximum so that it's inactive. The crossover needs to be controlled exclusively by the amp, which you need to configure correctly.

2. DTS HD MA can be anything from 1.0 to 7.1. Your Onkyo will automatically process as many channels as there are and attempts to override its decision can only cause problems.

3. Biwiring (running two wires from one amp to one speaker) is a con to get you to spend more money on speaker cable. You can achieve the same benefit for less outlay by using thicker wire, but once you reach 2.5mm, increasing the area won't yield anything. 1.5mm ought to be adequate for typical domestic usage.

Thanks mate. That answers alot of questions.

I currently have 2.5mm cable so thats ample. When i put my ear to the rears they dont seem to be up to much in dts HD master. i will keep listening.

That's normal. You can configure your Onkyo to "split" what goes to the surrounds in 5.1 to go to the surrounds and rears. This will enable you to get as much use out of the rears as the surrounds.

Hmm, i will look in to that. I have just managed to get toy story 3 which it says on the box is 7.1. that will be a good experiment tonight.

There are 2 settings on my Onkyo that also confuse me. when watching a TV show that i have grabbed it is mostly in stereo but occasionally in 5.1. the amp has a setting thats "TV Logic" and "DIRECT"

What are these sound settings?

TV Logic: I found this info...

"This mode adds realistic acoustics to TV shows produced in a TV studio, surround effects to the entire sound, and clarity to voices."

Direct:
"In this mode, audio from the input source is output directly with minimal processing, providing high-fidelity reproduction. All of the source's audio channels are output as they are."

I found this info elsewhere, however I kind of knew what they were because almost all AVR's have similar settings.

Basically there's lots of settings that offer "simulated" surround when listening to stereo broadcasts for example dolby pro-logic or Neo 6....which is better is totally down to the ear of the beholder.

Direct is just that, as little as possible is done in terms of your AVR processing the sound and so the signal is amplified in the simplest way and sent to your speakers.

Bottom line here I think is have a play, see what you like and make these your favourites by setting them in your memory pre-sets.

All the best and enjoy!
