Various Speaker Settings
LX83 LX73 LX53
Previous A/V receiver models only allowed surround back
speakers for a 7.1-channel layout (Fig. 1).
This year's lineup provides more options in terms of speaker
placement. Combine front wide speakers (Fig. 2) with
Pioneer-original Wide Surround mode to enjoy more spacious
sound in the front. Or place front height speakers (Fig. 3) and
use Dolby Pro Logic IIz for vertical-spreading sound.
Wide Surround Mode
LX83 LX73 LX53
Pioneer's Wide Surround Mode creates sound with dense
motion feeling around the front and sides. Wide Surround
Movie provides motion feeling in front, while Wide Surround
Music creates a wide-spreading sound field in the foreground.
Dolby Pro Logic IIz
LX83 LX73 LX53
Dolby Pro Logic IIz realises more spacious
surround sound by adding front height
channels to the conventional 5.1ch/7.1ch
speaker settings. The enveloping sound with
additional depth and dimension creates a lifelike listening
experience. Dolby Pro Logic IIz does not require special content,
and works with existing soundtracks.
Virtual Height
LX83 LX73 LX53
If you want to experience vertically falling sound but can not
place front height speakers, there's a perfect solution.
Pioneer's newly-developed Virtual Height mode (Fig. 4) creates
a height sound image without front height speakers, letting you
enjoy enveloping virtual 7.1-channel sound from 5.1-channel
speaker settings.
Virtual Surround Back
LX83 LX73 LX53
Want to be thrilled by surrounding sound from behind, but
don't have the space for surround back speakers? Then try
Virtual Surround Back mode (Fig. 5). It simulates 7.1-channel
surround sound, giving the impression of surround back
speakers when listening to a 5.1-channel source. What's more,
by turning on both Virtual Height and Virtual Surround Back
modes, you can enjoy virtual 9.1-channel sound on a
5.1-channel speaker setting. By adding front wide speakers, you
can enjoy virtual 11.1-channel sound from a 7.1-channel speaker
layout.
