Trouble with DD processing

[Jack Hammer]

HI,

I'm not sure what is causing problems with the sound in my reciever. Here is what has been happening.
I bought a denon 2805 reciever a few months back and am quite impressed with the sound of it. However, I've had a few problems with the sound level, especially in the center channel, while watching movies in dolby, DTS works fine. At first I thought it was my dvd player, but after reading all the great reviews on it (pioneer dv578a) I figured maybe it was the newest component, my reciever. Oh, I've had the dvd player for close to a year w/o any problems. When watching movies the center would become almost inaudible while the fronts and the surrounds would play at extremely high levels. This was both through the external inputs and the toslink connections.

I reset the microprocessor on the reciever to see if it would help and the sound came back. But after a week and a half it dropped out again. I reset the microprocessor again and it has been fine for the last week. Now I'm paranoid that something is wrong with my reciever. I've tried to reach denon a few times, but after 45 minutes on hold I gave up.

I'm not sure what is causing this. Any suggestions or ideas would be greatly appreciated.

TIA
Jeff


Here is my current setup:

Denon 2805 reciever
Pioneer dv578a dvd player
PS2
RCA 36" tubed tv
M&K speakers
AR ProII interconnects

I have the Denon 2805 and the Pioneer 578a combination and the center channel on DVD's is weak for dialogue. But this problem is not unique to our setup. Many players have an enhancement circuit for dialogue and, not having the menus in front of me, may or may not appear in the 578a.
What I did was run the microphone tone burst tests for the initial setup and then go into the Denon menu and manually boost the center channel and the subwoofer ( which came out at 19 ft in the setup). I am still not completely happy with the dialogue levels either, but I don't think it is a fault with our equipment.

It's almost no volume sent to center...

The main problem isn't a weak volume level, it is almost no volume level. I've had to reset the microprocessor (restores all settings to how shipped from factory) in order to get the center chanel to play above a whisper. Once reset the volume level comes back and everything plays fine.

I don't know what is causing the the processor to stop sending a "full" audio signal to the center channel. Has anyone ever had this problem?

I've had the best results contacting Denon via e-mail.

Sure sounds like something is amiss if it comes back after resetting the system.

Thanks,

I'll give that a try.

Give them the model number, serial number, place and date of purchase, etc. Seems to get the best results if they've got all the info. Describe the problem and solution as you have here and tell them you've tried the DVD player on another receiver and the problem didn't occur.

Good luck
