Sherbourn Technologies Uncover the Enhanced Audio Experience with the Sherbourn PT-7010A

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.

See page 40 for information regarding the adjustment of the bass management crossover point.

Note: The SPEAKER SIZE menu is used to set the bass management correctly for your speaker system. See page 37.

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
