Better sound using Phase Control and
Full Band Phase Control
This r eceive r is equi pp ed with the two ty p es of functions
that co rr ect p hase disto r tion and g r ou p delay: Phase
Cont r ol and Full Band Phase Cont r ol. Activating Full
Band Phase Cont r ol is st r ongly r ecommended because it
also involves the effects of Phase Cont r ol. Fo r details on
each of these two featu r es, r efe r to the following
ex p lanations.
Using Phase Control
Du r ing multichannel p layback, LFE (Low-F r equency
Effects) signals as well as low-f r equency signals in each
channel a r e assigned to the subwoofe r o r othe r the
subwoofe r and the most a ppr o pr iate s p eake r . At least in
theo r y, howeve r , this ty p e of pr ocessing involves a g r ou p
delay that va r ies with f r equency, r esulting in p hase
disto r tion whe r e the low-f r equency sound is delayed o r
muffled by the conflict with othe r channels. With the
Phase Cont r ol mode switched on, this r eceive r can
r e pr oduce p owe r ful bass sound without dete r io r ating the
quality of the o r iginal sound (see illust r ation below).
Phase Control OFF
• Rhythms blu rr ed and difficult to hea r
• Bass sound with loss of de p th
• Sound of musical inst r uments with no r eality
Phase Control ON
• Rhythms with c r ystal-like cla r ity
• Bass sound with no loss of de p th
• Sound of musical inst r uments with su p e r b r eality
Note
1 • You may need to check the digital audio out p ut settings on you r DVD p laye r o r digital satellite r eceive r . It should be set to out p ut Dolby
Digital, DTS and 88.2 kHz / 96 kHz PCM (2 channel) audio, and if the r e is an MPEG audio o p tion, set this to conve r t the MPEG audio to PCM.
• De p ending on you r DVD p laye r o r sou r ce discs, you may only get digital 2 channel ste r eo and analog sound. In this case, the r eceive r must
be set to a multichannel listening mode (see Listening in surround sound on p age 35 if you need to do this) if you want multichannel su rr ound
sound.
