Additional information 13 Glossary Audio formats/Decoding Dolby The Dolby technologies are explained below. See http://www.dolby.com for more detailed information. Dolby Digital Dolby Digital is a multichannel digital audio coding system widely used in cinemas, and in the home for DVD and digital broadcast soundtracks. Dolby TrueHD Dolby TrueHD is the lossless encoding technology developed for high-definition optical discs in the upcoming era. Dolby Digital Plus Dolby Digital Plus is the audio technology for all high-definition programming and media. It combines the efficiency to meet future broadcast demands with the power and flexibility to realize the full audio potential expected in the upcoming high-definition era. Dolby Digital Surround EX Dolby Digital Surround EX (the EX stands for EXtended) is an extension of Dolby Digital encoding whereby a surround back channel is matrixed into the surround left/right channels for 6.1 channel playback. This allows for compatibility with Dolby Digital 5.1 channel decoding, as well as for decoding using Dolby Digital EX. Dolby Pro Logic IIx and Dolby Surround Dolby Pro Logic IIx is an improved version of the Dolby Pro Logic II (and Dolby Pro Logic) decoding system. Dolby Surround is an encoding system which embeds surround sound information within a stereo soundtrack, which a Dolby Pro Logic decoder can then use for enhanced surround listening with greater sound detail. Dolby Pro Logic IIz Adding a pair of speakers above the front left and right speakers adds expressiveness in the vertical direction to the previous horizontallyoriented sound field. The height channel strengthens the sound field's sense of threedimensionality and air, producing presence and expansion. DTS The DTS technologies are explained below. See http://www.dts.com for more detailed information. DTS Digital Surround DTS Digital Surround is a 5.1-channel audio coding system from DTS Inc. now widely used for DVD-Video, DVD-Audio, 5.1 music discs, digital broadcasts, and video games. DTS-HD Master Audio DTS-HD Master Audio is a technology that delivers master audio sources recorded in a professional studio to listeners without any loss of data, preserving audio quality. DTS-HD High Resolution Audio A high definition audio technology by which signals can be transferred over HDMI cables. DTS-ES DTS-ES (the ES stands for Extended Surround) is a decoder that is capable of decoding both DTS-ES Discrete 6.1 and DTS-ES Matrix 6.1 encoded sources. DTS Neo:6 DTS Neo:6 can generate 7.1 channel surround sound from any matrixed stereo source (such as video or TV) and from 5.1 channel sources. DTS Neural Surround DTS Neural Surround can generate 7.1 channel surround sound from any matrixed stereo source (such as video or TV). Decoding A technology for converting digital signals that have been compressed upon recording by a digital signal processing circuit, etc., into the original signals. The term "decoding" (or "matrix decoding") is also used for the technology which converts 2-channel sound sources into multiple channels or expands 5.1-channel signals into 6.1 or 7.1 channels. Calibrating the sound field/ Improving the sound quality Phase Control The Phase Control technology incorporated into this receiver's design provides coherent sound reproduction through the use of phase matching for an optimal sound image at your listening position. Virtual Surround Back When you're not using surround back speakers, selecting this mode allows you to hear a virtual surround back channel through your surround speakers. You can choose to listen to sources with no surround back channel information. Virtual Height When you're not using front height speakers, selecting this mode allows you to hear a virtual front height channel through your front speakers. Auto Sound Retriever The Auto Sound Retriever feature employs DSP technology to restore sound pressure and smooth jagged artifacts left over after compression. With some audio inputs, the Sound Retriever effect is automatically optimized based on the bitrate information of the contents that have been input to achieve high sound quality. Sound Retriever Air Sound Retriever Air compensates for reduced sound quality due to compression when sending Bluetooth signals. PQLS Jitterless high quality playback is possible by connecting a PQLS-compatible player with HDMI connections. ALC (Auto Level Control) In the Auto level control (ALC) mode, this receiver equalizes playback sound levels. Also, the low and high frequency sounds, dialogs, surround effects, etc., that are difficult to hear when the volume is low are adjusted to be optimal for the volume level. This mode is particularly optimum when listening at night. Front Stage Surround Advance With the Front Stage Surround Advance feature, you can enjoy seamless, natural surround sound effects using only the front speakers, without deteriorating the quality of the original sound. MCACC The Auto MCACC Setup provides a quick but accurate surround sound setup, which includes the advanced features of Professional Acoustic Calibration EQ. HDMI Control with HDMI function Synchronized operations below with a Control with HDMI-compatible Pioneer TV or Blu-ray disc player or with a component of another make that supports the Control with HDMI functions are possible when the component is connected to the receiver using an HDMI cable. ! The receiver's volume can be set and the sound can be muted using the TV's remote control. ! The receiver's input switches over automatically when the TV's input is changed or a Control with HDMI-compatible component is played. ! The receiver's power is also set to standby, when the TV's power is set to standby. En 83
