5-Channel Equal Power
5-Channel Equal Power connects 5 speakers independently without requiring separate power amps for the pre-outs. It complements Dolby Digital EX and dts ES sound modes, allowing you to connect the 'surround back' speaker straight off the main amplifier without adding a power amplifier to support 5.1 surround formats. With built-in separate internal amplifiers to power each channel independently, this feature allows you to enjoy the same high power output capability per channel, giving a balanced and truly high-impact surround-sound environment.
Dolby Digital
Dolby Digital is the multi-channel digital signal format developed by Dolby Laboratories. Dolby Digital consists of up to 5.1 channels – front left, front right, center, surround left, surround right, and an additional channel exclusively reserved for additional deep bass sound effects. Dolby Digitals main channels can all contain full range sound information, from the lowest bass, up to the highest frequencies – 22 kHz. The signals within each channel are distinct from the others, allowing pinpoint sound imaging and tremendous dynamic range from the most powerful sound effects to the quietest, softest sounds, free from noise and distortion.
Dolby Digital Plus
Next-generation multichannel audio format. Delivers up to 7.1 channels of better-than-DVD-quality surround sound in Blu-ray discs. Advanced coding efficiencies facilitate BD-Live and Bonusview playback and enable rich surround sound audio from digital broadcast,IPTV,and streamed and downloadable media.
Dolby Pro Logic IIx
Dolby Pro Logic IIx furthers the matrix decoding technology of Dolby Pro Logic II to decode audio signals recorded on two channels up to 7.1 playback channels, including the surround back channel. Dolby Pro Logic IIx also allows 5.1-channel sources to be played in up to 7.1 channels. The mode can be selected according to the source – Music mode is best suited for playing music, Cinema mode for playing movies, and Game mode for playing games.
