Harman kardon avr-147

I just bought a harman kardon avr-147 receiver I hookedit up to my HD cable box from time warner through the optical input and every time I change channels on my cable box the receiver changes in different dsp/dts modes for example if I have it in 4 channel mode it goes to dolby digital or hall 1 or dolby movie,dolby music and it is very annoying does anybody know how I can stop this. I've tried unpluging it but it doesn't work i read the whole manual and it doesn't say anything about that.

    Same problem as above ~ However, the Center Speaker does not sound up to quality once receiver detects the channel's digital setup.

Hi Javis. This is perfectly normal ! This mode change is done because the receiver auto detects the digital audio signal and sets the receiver's DSP to decode the signal correctly. You can go into the OSD menu to bypass the auto detection of it, but it's not recommended at all ! You're getting the best audio quality by doing so. Thanks ! cheebster.

The inputs may be assignable on the Harman Kardon. Make sure you have selected the proper analog or digital input type for the cable you are using.

Which optical port in the back of the receiver goes to the optical port on the back of my HDTV

The manual talks about that.

Any of the three INPUTS if you're bringing sound IN from the TV or elsewhere; or the lone OUTPUT if you want to send audio to the TV or elsewhere.

If the former, consider sourcing the audio from the REAL original source of the program you're watching, most likely a Cable Box. Less cabling and fewer connections to fail.

Just bought a Sharp LED TV and there is a slight delay between hearing sound and seeing lips move. Have cable box hooked up to tv by HDMI and have cable box hooked to AVR (Harmon Kardon AVR125) by optical...

Hi if there is an optical out on the television i would use that direct to your Harmon Kardon AVR 125, the sound would be in sync with picture, as the source is the same.

Fiber Optic input

No gots. The 3485 is pre-digital stereo-only.

From the manual, page 19

"You may have observed that the HK 3485 is not equipped with digital audio inputs or surround sound decoding. If you prefer the complete home theater experience, you may wish to consider purchasing a fullfeatured Harman Kardon AVR Series audio/video receiver. However, we hope you will find that using a DVD player with the HK 3485 in smaller settings, such as a bedroom or den, surpasses the audio performance of most televisions, including those with onboard stereo speakers."

Can I conect harman Kardon avr 230 to apple tv

Yes, although it (AVR) does not support HDMI only component video.

Connect the audio to the receiver and the video directly to the TV if you have inadequate video inputs, or want to take advantage of the HDMI.

Harmon kardon 745 displays "unlock" no sound for tv or movies

I also had this UNLOCK message on my Harman Cardon AVR 130.
The reason for this error was - in a hurry I've plugged the optical input into optical OUT! Double check that your connections in the back are correct and hopefully it fixes your problem.

Cheers,
Sergey

Lost 3.2.1 surround function when I hooked up new plasma

HDMI cables contain both your audio & video in one cable. Remove your optical cable from the box and disable in in the cable box menu and that should fix your problem.
