1. Secondary Audio
To set the Secondary Audio Program mixing option. Some Blu-ray discs contain a secondary audio and video program, such as a director’s commentary. Some Blu-ray Discs have a sound effect when you make menu choices. This Setup Menu item allows you to decide whether to mix the Secondary Audio Program and menu clicking sound into the primary audio. The options are:
On – The Secondary Audio Program and menu clicking sound are mixed into the primary audio. Usually this will cause the primary audio volume to be slightly reduced. High resolution primary audio will be converted to a normal resolution in order to mix with the secondary audio.
Off – The Secondary Audio Program and menu clicking sound are not mixed into the primary audio and you cannot hear the secondary audio or menu clicking sound. This setting preserves the highest possible audio quality for the primary audio.
2. HDMI Audio
To select digital audio output format from the HDMI output. The options are:
Auto (default) – The player checks with the device connecting to HDMI output to automatically determine which audio format to use.
LPCM – Digital audio output via HDMI will be multi-channel Linear PCM format. When this option is selected, compressed audio bit streams will be decoded by the player and then sent as multi-channel PCM. This setting is recommended when connecting the HDMI output directly to a TV or to a receiver without advanced audio decoding capabilities.

Bitstream – Digital audio output via HDMI will be in bitstream format. | ENGLISH |
receiver or processor that supports advanced audio decoding of Dolby |
This option is recommended when connecting the HDMI output to an A/V | |
TrueHD and DTS-HD Master Audio etc. | |
Off – No digital audio output via HDMI. | |
Note: If you use HDMI to connect audio to an HDMI A/V receiver or audio | |
processor, it is important that you choose 720p or higher HDMI output | |
resolution when playing high resolution audio content (DVD-Audio, | |
SACD, Dolby TrueHD and DTS-HD Master Audio). According to the HDMI | |
specification, the bandwidth available for audio is proportional to the | |
total bandwidth used by video. At 480p/576p resolution, the HDMI | |
specification can only support 2 channels of audio with high sample rate | |
(up to 192kHz), or 8 channels of audio with standard sample rate (up to | |
48kHz). If you play high resolution audio content at the 480p/576p | |
resolution, you may get reduced audio resolution, incomplete audio | |
channels, or even no audio/video output at all. Choosing a higher output | |
resolution such as 720p or above allows enough bandwidth for all high | |
sample rate audio channels. | |
3. Coaxial/Optical Output
Used to set the output format for the coaxial/optical digital audio outputs. The options are:
LPCM – Forces down-mixed 2-channel digital audio output. Choose this setting if your receiver/amplifier or DAC only supports stereo digital (PCM) audio.
Bitstream – Passes audio as compressed bitstream format to the receiver/amplifier. Choose this setting if your receiver/amplifier is capable of decoding Dolby Digital and/or DTS etc.
4. LPCM Rate Limit
To set the maximum Linear PCM output frequency for the coaxial/optical digital output. This menu item is intended to ensure that the audio output is compatible with equipment that cannot support high sample rates. It sets an upper limit to decide whether the player shall down-sample audio. The options are:
Note: When using the Stereo or 7.1 Analog Audio outputs the LPCM rate limit should always be set to 192kHz to allow the internal playback engine to feed the up-sampler with the maximum sample-rate the content supports.
48kHz – Supported by most equipment. Higher sample rate material will be downsampled to 48kHz.
96kHz – Allows a higher sampling rate and frequency response. If using an externally connected AV receiver or DAC via coaxial or optical, ensure that the receiver/amplifier can support it. Higher sample rate material will be downsampled to 96kHz.
192kHz – Allows the highest sampling rate and frequency response. If using an externally connected AV receiver or DAC via coaxial or optical, ensure that the receiver/amplifier can support it.
5. SACD Output
To select audio output format for SACD. The options are:
PCM – SACD Direct Stream Digital (DSD) data is decoded by the player and converted into multi-channel, high resolution PCM data. The HDMI output can be sent to an external AV receiver capable of receiving multi channel PCM (HDMI 1.1 or higher inputs are required). The 651/751BD’s own audio outputs are also active and playback of SACD material is possible by the 651/751BD itself.
DSD – SACD DSD data is output over HDMI without any conversion. For decoding by an external AV receiver capable of receiving DSD (HDMI 1.2a or higher inputs are required and the receiver must actually include support for DSD as it is not a mandatory requirement of the HDMI spec).
