Haier HEC BDP100 Blu-ray Disc Player - Audio Settings
Here is a look at the Audio Settings menu for the BDP100.
The PCM downsampling setting sets the bitrate for PCM signals when using the BDP100's digital coaxial audio output (this setting does not affect HDMI audio output signals).
Without getting into the "techie" stuff, some home theater receivers can accept a 48Hz sampling rate, while others can accept both a 48Khz or 96KHz sampling rate. The 96Khz rate provides a better result, but you have the option depending on your receiver's capabilities.
Also, it depends on the sampling rate used for the disc soundtrack. Check your home theater receiver's user manual for sampling rate capability. If you are using the HDMI output for audio, you can set this option to "OFF".
If you have a home theater receiver that has HDMI audio access and built-in Dolby TrueHD and DTS-HD Master Audio decoders, it is best to set the Digital Output to "Bitstream HD".
Also, in cases where there may be both a picture-in-picture commentary or other secondary audio track on a Blu-ray Disc, then you need to reset the top section to "Bitstreamed Mixed".
However, if you do not have a home theater receiver with built-in decoders for Dolby TrueHD and DTS-HD Master Audio, then you have the option of setting the digital audio output to "Bitstream Legacy". This setting will send a signal to your home theater receiver to decode all digital audio output signals as either standard Dolby Digital 5.1 or 6.1, or DTS 5.1 bitstreams that can be recognized and decoded by an older Dolby Digital/DTS home theater receiver.
On other selection that is available is PCM 5.1 or 7.1. What this does is allow the BDP100 to do its own internal decoding. However, you need a receiver that can accept PCM over HDMI for best effect, as the transmission of PCM over a digital coaxial output is limited to two channels.
Dynamic Range Control evens out audio output levels from Dolby Digital tracks so that loud parts are softer and soft parts are louder. If you are bothered by extreme volume changes (such as explosions and crashes) this setting evens out the sound to you don't get as much sonic impact from the differences between soft and loud sounds.
