Setting Up Your Home Theater 101 - Page 3

post #61 of 202
Hello,

I'm still educating myself in the Home Theater Audio arena so bear with me. I've read quite a bit and gotten my system (Yamaha HTIB YHT-380) to a good place but have one remaining issue I'm having trouble finding information on.

A) LFE/Bass Out: In this option I can select the speakers that output the LFE signal to the Subwoofer only or to both the Subwoofer and Front speakers. Which is the best option? I try to use my ear to just say, "this sounds better" but I'm still getting used to having surround sound in general so it's kind of a bombardment of stimulation at this point. Also, I wouldn't know if something else was the byproduct of this setting (good or bad).

B) Dynamic Range: In this one, I can select the amount of "Dynamic Range Compression" to be applied to my speakers. Options are Min., STD, and MAX. The description of each one doesn't exactly clarify what I'm changing. Right now, I would say that the difference between a regular scene containing dialogue/atmosphere and a heavy action scene are a bit much. I want those regular scenes to be a good volume but I don't want to shatter the windows when somebody goes berserk with a shotgun. It says that MAX preserves the greatest amount of Dynamic Range. Does that mean the range is larger? If that is so, does that mean that setting it to anything else is altering the signal and possibly degrading it or losing tonal range?

Any and all help is greatly appreciated.

A) Set all your speakers to small and set the LFE/Bass Out to SWFR only. Set your crossover to 80Hz or 100Hz for the subwoofer.

B) Set to max, as it will the to preserve the greatest amount of dynamic range for your particular receiver.

sorry for the late response. I dont check this thread to often.

post #64 of 202
Was wondering if I could get some advice about setup, in that I don't have an HD in my home theater currently. My setup is completely underground, with no ambient light at all. Purchased Samsung DLP 67" to replace a Hitachi SBX60 that is 10 years old (still looks great but analog).

I have a Denon AVR 2801 with the Klipsch Quintet surround speakers with the 12" Klipsch woofer. This receiver does not have HDMI connectivity. I am totally satisfied with the audio quality with these speakers and this receiver. I'm wondering what my options are relative to hookups and whether I need a new AV receiver because of the new Samsung. If I do need a new receiver, how many HDMI ports should I be looking for?

I will be using DirecTV HD with DVR service. I also have non high definition Comcast cable (for local Philadelphia sports only, and a better price on cable modem; not currently planning on upgrading this as well). I have a regular DVD player, and do not own any high def gaming systems.

Any advice would be greatly appreciated.

Hey Guys...

AM about to install a set of B&W M1's and am figuring out where to put my rear speakers.

At the moment i'm thinking of placing them at each corner just below the ceiling. Is this an OK placement? I've had some advice that it needs to be lower down and not too high up, etc..

Any tips?

If the ceiling is too high, do you know if B&W do a custom extension bracket where it can be hooked into the ceiling but extended down lower?

My issue is that my 'blackout' curtains go from ceiling to floor so its a problem to install the speakers on the wall...

The other alternative of course is to get the normal speaker stands...opnly thing is i've got small kids...and for those of you who have these little creatures running around, you know what their like with things their not supposed to be messing with!! ha ha...

Thanks people. Hope someone can give me some tips.

Cheers,
Straven

Adding a Receiver

For some reason I can't wrap my mind around this. I have a 5070.
Here is the setup now.

Tosh SD5000 - HDMI
XBox 360 - Composite
SA-8300HDC - HDMI

Speakerbar along with Sony sub

Due to budget and apartment constraints I plan on getting the Pioneer HTS-GS1 HTIB.

The HTIB has three digital connections (2 optical 1 coax)

Here is where my confusion steps in.

Do I keep the above components connected like they are, then connect each components (digital audio out) to the "receiver".

Or do I connect the digital audio out on the 5070 to the receiver?

I'm trying to get 5.1 sound (when applicable) and not have any lip sync issues. It seems that if I do not connect the digital audio out on the 5070 to the receiver that I could get lip sync problems, but I may not get the 5.1 sound (again, when applicable).

Would any/everyone mind helping out?
Sincerely appreciated

Skid

I understand how to calibrate my system for 5.1 with the SPL meter etc..

but I'm curious how everyone calibrates their surrounds when using a 7.1 system.. especially when they listen to 7.1 discrete PCM tracks on Blu-ray.
Do you calibrate each of the 4 surround speakers independently?
OR do you calibrate each channel independently? i.e. as if you're setting up your 7.1 to listen to both 7.1 or 5.1 material, by calibrating the left surround of the 5.1 channel with both Side-Left surround AND back left surround turned on together?

I've looked through these calibration 101 posts, but no one seems to clarify this. It's important because it could be +/- 3dB either way.

Thanks for any help!

A very nice collection of links, Dr. Thanks!

One thing i'd like to know more about is the setup of acoustical absorbers (or diffusers, or bass traps) specifically in a dedicated home theater room (i.e. not just 2 channel audio). It seems the fiberglass based products are viewed as superior to foam, so you might want to link to threads discussing the various products (either DIY or ready-made), and placement of the treatments. I understand treating the first reflection points on the side walls, but how much is needed (i've read up to 30% of wall surface area should be covered!), where else is it needed (i.e. entire wall behind front speaker), etc? I read things about treating from the floor to the listening height all around the side and rear walls, but i don't really understand that much. Also, what about floor and ceiling treatment? I've again read conflicting reports of what's recommended, especially on the floor, since carpets and rugs can be "comb" absorbers.

Thanks again!

Well, i stumbled onto this thread: Acoustics Discussion for Dedicated HT

It answers alot of my questions, although a consensus would still be nice

Sadly, I don't have any, or I wouldn't be looking for them myself...

I bookmarked the page though, for when I want to read up more on audio information (after I fix some issues in other areas of my setup...).

Thanks. Sometimes I add stuff quickly to the thread in the first few minutes after I initially post if I think of something suddenly. This way I don't have to keep adding new posts to a thread and unintentionally clutter it, which to most people is much more annoying...

the thing im wondering about most is wattage. is comparing the wattage of the receiver and speaker the most crucial part? obviously im worried about blowing speakers or the receiver, etc, so i just want to make sure im pairing the right components. for example, i have JBL scs500.5 speakers, that say they have impedance of 8 ohm and maximum amplified power of 100 watts. the receiver im planning on getting is the Onkyo TX-SR705, which says it has an output of 100 watts per channel. Do these matching wattages mean that I am good to go? or are there other settings that need to be adjusted? i read the link about power, but a lot of the terms used in that are not used in the manuals of the components i have, making it a little harder. if anyone can elaborate on what you need to look at in terms of power thatd be awesome.

thanks

Thanks very much DrPain.


I just purchased an SPL meter from Radioshack and did the prescribed calibration.


HOLY CRAP

I can't believe what a difference it made. Absolutely fantastic,my HT immersion has gone up 100%. Definitely worth the $44.99 I spent on the SPL meter.

I just calibrated my system. Set the meter to 70, set the volume on my receiver so the needle hovers around 0db. I then adjusted everything to the +5db setting. Supposedly I'm at 75db for my speakers, and my sub is 85db at my reference level.


What do I need for more accurate results?

saw this from another post you had...

Dial the sub in at 72db or so (72db is to compensate for the inaccurate reading the meter gives for bass) . Set your AVR to -5db for the sub and adjust the sub gain on the subwoofer until you reach 72db on the rat shack. Any more than that you'll be running the sub "hot"

Keep asking questions until your satisfied.

If I can, should I bi-wire my speakers?
And if I should how would I go about doing it? And why isn't the banana plug yellow?

I have a Toshiba XA-2 HD player hooked up to my Yamaha
RX-V2400. I want to add a blu-ray player to the receiver also. For my 5.1 channel RCA audio hook-up on the back of the receiver, can I put a Y adapter to each RCA input so both machines can be hooked up at the same time? I would only turn the power on the player I would be using.
