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.

Re: harman kardon avr-147
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. For more information, or should you have further questions, please visit my website at audioserviceclinic.com. You may contact me directly through the website. Thank you.
"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."
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.
