Samsung ht-c550 dolby pro logic II mode does not work.

Hello
If subwoofer is inactive now, the sound preference settings you set now is wrong.

Before using the remote control for the following
operation
* Set the remote control mode selector to AUDIO

** There are exceptions in the operation mentioned
above. In such a case, follow each instruction

Dolby Pro Logic II*1

# Dolby Pro Logic II has a newly developed multichannel playback

format to decode all 2 channel sources - stereo source and Dolby

Surround encoded source - into a 5.1 channel.

hi,
there are some setting to make the aux input to make it 5.1. but it will be not a real 5.1. the processor inside will stimulate the 2 channel input to 5.1. for that press dolby pro logic ll mode button on ur remote control or dolby pro logic ll effect button. by the use of second mentioned button u can select different type of effects.
ok

I had the problem and after pressing the DVD Receiver\DVD button to no avail went back to setup and turned the ASC Setting to off. Apparently I had forgotten to turn it off after doing the Auto Calibration.

Hope this helps.

For an outside left/right(red/white or stereo jack), enable Dolby Pro Logic or ProLogic II. For DVD's, if it doesn't have a 5.1 track, which will be stated on the back of the DVDcase, then also will be a case where ProLogic is needed.

How is the cable box audio connected to the Samsung? That is where the sound comes FROM. HDMI carries signal TO the TV.

The single optical digital input is a limitation if you get HDTV through cable. You probably use it for the DVD.

I found this quote from the manufacturer's propoganda, "deliver the greatest impact from all your digital media". Yeah, all ONE hardware source of it.

You could manually attach the optical output (if it exists) of the Cable Box to optical input on the Samsung for multichannel-audio TV viewing (listening). OR, you could run the RCA L&R analog audio outputs out of the Cable Box into one of the Aux Inputs, but no actual surround will be produced.

Check connections.

Make sure you are on the correct Input/Source, adjust volume acordingly.

Please give details about what sources and connections you are using.

The P.BASS function is only available with 2 channel LPCM sources such as mp3,Divx,cd
and wma. Press P.BASS button and "POWER BASS ON" will be displayed on the screen.
The P.bass does not work with DSP/EQ or DOLBY PRO LOGIC ll modes.
If you press P.BASS in the DSP/EQ mode, the DSP/EQ mode is automatically shut off and the P. BASS function comes on.
The DSP/EQ function is only available in STEREO mode.
Press the PL ii mode button to show STEREO on the display.
This feature works with CDs, MP3-CDs, 2 channel DVD-Audio, DivX and Dolby Digital discs.
When playing a DVD disc encoded with two or more channels, multi-channel mode will be selected automatically and DSP/EQ function does not work.

Hi, maybe,like my HT-THX25, my book states that sound will only be heard from the rear speakers when in DVD 5.1 or Dolby Pro Logic 11 mode, peronally I would love to hear sound from any of my speakers when TV is on lol. Geoff
