Adjusting the Acoustic Image (81-
PHANTOM)
To install a center speaker, it must be located in the dash, an equal
distance between the Left and Right speakers. In most cases, this is very
difficult to achieve. Using Bi-PHANTOM, a virtual center speaker is
created by sending the center channel information to both the Left and
Right speakers. Adjusting the center width in Dolby Pro Logic II
"Music" (see "Using Dolby Pro Logic II (Dolby Pro Logic II)" on
page 31), makes this function ineffective. (Initial setting: "OFF",
"±OdB")
} Click [ON] for "81-PHANTOM."

Level: -5 to +5 dB (in 1 dB step)
The level can be adjusted between -5 and +5. When the
level becomes greater, the acoustic image moves from the
center speaker location towards both sides.
• Avoid stopping, pausing, switching the disc, cueing, fast-forwarding
or switching the audio channel of this unit while making this
adjustment. The setting is cancelled
if
the decode mode is switched.

Mixing the Low Range Audio for the Rear
(Rear Mix)
This function mixes the front channel audio signals with the audio
signals output from the rear speakers, improving the sound in the
vehicle's rear seat. This is used in a system where there is no subwoofer
and the rear speakers can produce lower frequency sounds than the front
speakers. (Initial setting: "OFF", "±OdB")

Click [ON] for " Rear Mix."

effect may vary.)
