Special Features of the
Sherbourn PT-7010A
Bass Management
Unlike higher frequencies, it is difficult to discern exactly
from which direction lower bass is coming. The PT-7010A
has a bass management system which takes advantage of
this effect. It allows you to choose whether your speakers
will play the full frequency range, or if the bass will be
redirected to the subwoofer.
The advantages of redirecting the bass to a subwoofer
include the following:
The overall bass of the system is improved as sub woofers
are specially designed for this frequency range.
• The subwoofer can simultaneously play the bass from
all of the speakers, in addition to its own low frequency
effects channel (LFE).
• There is no loss in perception of the position of movie or
music sound effects, as the ear cannot easily locate the
position of low frequency sources.
• Smaller speakers can be used for main front, center and
surrounds, as they do not have to reproduce the low
frequency range. This leads to a saving in speaker expense
and room space. A subwoofer is required if the front
speakers are set to SMALL.
• Your amplifiers do not waste power reproducing the low
frequency range when using a powered subwoofer. Nearly
all home audio subwoofers are self powered.

the bass management crossover point.
Note: The SPEAKER SIZE menu is used to set the bass
management correctly for your speaker system. See page

Dolby Digital and DTS modes are designed especially for
complete systems with front, center, and surround speakers
and subwoofers. You need all of the speakers to get the
best performance from your Home Theater. If you do not
have a subwoofer connected, then you should not use the
bass management system (so set all the speakers to Large).
Without a subwoofer, you will be missing the 5.1 LFE
(low frequency effects) information.
Considering the advantages of the bass management
system, you might try setting all of your speakers to Small,
even if they are capable of good low-frequency
performance.
Surround Modes for 2 Channel Source
Material
For 2 channel input sources, you can choose from the
following modes:
• STEREO
• DOLBY PRO LOGIC II or PRO LOGIC llx
• PARTY
• JAZZ CLUB
• DTS Neo:6
• SOURCE DIRECT
DOLBY PRO LOGIC II and DOLBY PRO LOGIC llx
This is the conventional two-channel stereo mode with
sound from your left and right speakers. The PT-7010A
bass management lets you use your subwoofer to handle
the lower frequency range. Dolby Pro Logic II has several
options which can be set using the On Screen Display
(OSD) menus. These include:
MOVIE mode for Dolby Surround soundtracks. These
are decoded by the PT-7010A into separate channels: left
and right channels for off-screen imaging, a center channel
for most on-screen dialog, and stereo surround channels
for ambience and special effects.
MUSIC mode for listening to any stereo material. This
mode also includes three options:
• Center Width, which spreads the center channel across
the front soundstage.
• Panorama, which wraps the left and right channels
around you.
• Dimension, which adjusts the front/rear balance of the
PLII or PLIIx effect.
Try the PLII or PLIIx MUSIC modes for all of your stereo
