surround effects

[jakester]

I have a Yamaha RXV 595A for the last 12 yrs or more, I haven't watched surround sound movies in a few years, we have some movies like in the Cut throat Island, we liked this movie because the front to rear surround sounds were nice, and there were more movies too, but for some reason I cannot get the sound effects back, I made alot of settings and made it worst, I did a factory reset on the Yamaha receiver it is better but the front to rear effects are not nowhere like they used to be, what adjustments on this Yamaha receiver would relate to the sound for like cannon balls flying thru the room or when a helicopter is flying where I used to hear the chopper blades throughout the room. and I do have a RS SPL meter and done the setting over and over tried different speakers ect. where am I going wrong here, I know it is definitely in the settings on the receiver but can't hit it right. my receiver is the older Yamaha it does not have the mic input for auto settings.

Hi, Chet. I forget some of the discussions about this in the other threads, so I'll probably be repeating something here.

• Do you have the receiver connected to a DVD player using only a digital audio cable?
• Do you have the DVD player set to send the bitstream audio to the receiver?
• Do you have the receiver set to a surround sound mode that will give you those effects (e.g. Dolby Digital)?
• Have you picked the Dolby Digital audio track on the DVD? Several DVDs default to the Pro-Logic audio track.
• Do you have the Yamaha DSP modes disabled so that you are only listening to the original Dolby Digital audio?

Adam, I will answer the best I can,

• Do you have the receiver connected to a DVD player using only a digital audio cable? I have a cable going out of the DVD player, digital out and that cable goes to the Yamaha receiver
  
  
• Do you have the DVD player set to send the bitstream audio to the receiver? I will check again, there was something about PCM too, whatever that means
  
  
• Do you have the receiver set to a surround sound mode that will give you those effects (e.g. Dolby Digital)? it says Dolby Digital Enhanced
  
• Have you picked the Dolby Digital audio track on the DVD? Several DVDs default to the Pro-Logic audio track. before I play a movie I select Dolby DTS or 5.1 which ever it has available.
  
• Do you have the Yamaha DSP modes disabled so that you are only listening to the original Dolby Digital audio? This I am not sure of, I believe they are enabled, will have to see if I can shut the DSP mode off

Adam I hope I answered the best I can.

I was looking in the rear of the Yamaha receiver, I am using the coaxial digital out on the DVD player, I do have another part that says Opt digital out and an optical in on the Yamaha, would there be any difference there, I don't have an opt cable at the present time to try it if you think it would make a difference.

Chet,

The optical connection should have the same effect as the digital coax connection that you are using now, so I wouldn't worry about getting an optical cable.

The "Dolby Digital Enhanced" mode is one of Yamaha's DSP modes. I don't think that one will cause the issue that you are having, but you could turn it off and check. I used that mode on occasion with my Yamaha, but I found that I preferred the original Dolby Digital audio. The "Enhanced" mode seemed to make things sound more diffuse, at least in my recollection.

I played the Master & commanders part in the beginning where the enemy starts to fire their cannons, there are a few selections on the DVD Dolby digital 5.1 and DTS the 5.1 has nowhere near the effects of the explosions ect. DTS brings it to life bigtime, so I guess I will keep it where it is for now, onething we did do last years was remove the carpeting in the room and replaced it with a hard type flooring, some type of a linoleum with a thick backer. this may relate to parts of the different effects, is that possible

Pretty much all room reflections are bad. Eliminating the carpet will increase the reflectivity of the floor at high frequencies. That causes comb filtering and accentuates high frequencies. The reflected sound arrives at your ear just slightly after the direct sound from the speaker, making a fine mess of things.

If you put a small mirror on the floor and place it so that the image in the mirror is of the speaker's tweeter(s), you can then replace the mirror with rugs which will eliminate those reflections.
