5 Listening to your system Listening with Acoustic Calibration EQ You can listen to sources using the Acoustic Calibration Equalization set in Automatically setting up for surround sound (MCACC) on page 23. Refer to these pages for more on Acoustic Calibration Equalization. RECEIVER SLEEP SOURCE 1 2 3 DISP 4 5 6 CH RECEIVER INPUT 7 8 9 CH SHIFT CLR 0 ENTER While listening to a source, press RECEIVER , then press EQ to switch the EQ (Acoustic Calibration EQ) ON or OFF. The MCACC indicator on the front panel lights when Acoustic Calibration EQ is active. • You can't use Acoustic Calibration EQ with Stream Direct mode and it has no effect with headphones. Better sound using Phase Control This receiver's Phase Control feature uses phase correction measures to make sure your sound source arrives at the listening position in phase, preventing unwanted distortion and/or coloring of the sound. Phase Control technology provides coherent sound reproduction through the use of phase matching for an optimal sound image at your listening position. The default setting is on and we recommend leaving Phase Control switched on for all sound sources. RECEIVER SLEEP SOURCE RECEIVER INPUT 1 2 3 DISP 4 5 6 CH 7 8 9 CH SHIFT CLR 0 ENTER While listening to a source, press RECEIVER , then press PHASE to switch the P.CTL (Phase Control) ON or OFF. Note • Phase matching is a very important factor in achieving proper sound reproduction. If two waveforms are 'in phase', they crest and trough together, resulting in increased amplitude, clarity and presence of the sound signal. If a crest of a wave meets a trough, then the sound will be 'out of phase' and an unreliable sound image will be produced. • If your subwoofer has a phase control switch, set it to the plus (+) sign (or 0°). However, the effect you can actually feel when Phase Control is set to ON on this receiver depends on the type of your subwoofer. Set your subwoofer to maximize the effect. It is also recommended you try changing the orientation or the place of your subwoofer. • Set the built-in lowpass filter switch of your subwoofer to OFF. If this cannot be done on your subwoofer, set the cutoff frequency to a higher value. • If the speaker distance is not properly set, you may not have a maximized Phase Control effect. • The Phase Control mode cannot be set to ON in the following cases: - When the PURE DIRECT mode is switched on. - When the headphones are connected. Using surround back channel processing You can have the receiver automatically use 6.1 or 7.1 decoding for 6.1 encoded sources (for example, Dolby Digital EX or DTS-ES), or you can choose to always use 6.1 or 7.1 decoding (for example, with 5.1 encoded material). With 5.1 encoded sources, a surround back channel will be generated, but the material may sound better in the 5.1 format for which it was originally encoded (in which case, you can simply switch surround back channel processing off). • With a 7.1-channel surround system, audio signals that have undergone matrix decoding processing through surround back channel processing to which the Up Mix function is added are output from the surround back speakers. 4 7 RECEIVER SLEEP SOURCE 1 2 3 DISP 4 5 6 CH RECEIVER INPUT 7 8 9 CH SHIFT CLR 0 ENTER Press RECEIVER , then press SB CH repeatedly to cycle the surround back channel options. Each press cycles through the options as follows: • SB ON - Matrix decoding processing for generating the surround back component from the surround component is turned on. • SB AUTO - Matrix decoding processing for generating the surround back component from the surround component is switched automatically. Matrix decoding processing is only performed when surround back channel signals are detected in the input signals. • SB OFF - Matrix decoding processing for generating the surround back component from the surround component is turned off. 62 Setting the Up Mix function In a 7.1-channel surround system with surround speakers placed directly at the sides of the listening position, the surround sound of 5.1-channel sources is heard from the side. The Up Mix function mixes the sound of the surround speakers with the surround back speakers so that the surround sound is heard from diagonally to the rear as it should be. • Using the Up Mix function is effective when the speakers in the 7.1-channel surround system are set up as recommended in the example on page 11. 36
