Parasound P/SP-1500 Center Channel Speaker Selector, Large or THX Wide Band, Small Normal

8 P/SP-1500 Owner's Manual

Center Channel Speaker Selector

Set this rear panel switch to accommodate the type of center channel speaker you will be using. Following are descriptions of the preferred center channel switch settings based upon the center speaker you will be using.

Large or THX (Wide Band)

Switch to the Large or THX position for center channel speakers that have extended low bass capability and can play as loud as your front left and right speakers without bass distortion. Use this setting for THX Home Cinema center speakers. In this position, the P/SP-1500 routes the entire audio bandwidth (20 Hz - 20 kHz) to the center channel output.

Small (Normal)

Switch to the Small position for smaller sized center channel speakers. In this position, the P/SP-1500 protects your center channel speaker from bass overload and distortion by diverting bass frequencies below 100 Hz to the left and right channels. In this position, front channel imaging remains tonally balanced even with the limited bass capability of a smaller center channel loudspeaker.

None (Phantom)

Switch to the None position if you do not have a center channel speaker. In this position, the front right and left speakers share reproduction of the mono center channel signal to create a “phantom” image in the center. However, without a good quality center channel speaker, you will be missing one of the key benefits of Dolby Pro Logic and THX Cinema processing.

External Remote Control Input

The external infrared input works with many popular infrared repeater systems to allow for remote control operation when infrared signals cannot directly reach the front panel receiver. The external remote input connector is a standard 1/8 inch (3.5 mm) mini jack. Wire the tip for this plug positive and the sleeve negative. Your Authorized Parasound Dealer or Custom Installer can recommend a compatible repeater system for your P/SP-1500.

DC Trigger

This connector provides a +12 Volt DC 350 milliampere capacity trigger whenever you turn on the P/SP-1500. Use this connector to activate equipment such as relays, rear screen projectors, motors for film screens, power amplifiers or other components that can be triggered with DC voltage. You can also use this DC Trigger connection to activate the two 15 Ampere relays in the optional Parasound SCAMP Signal Controlled Amplifier Power automatic switching component. Contact your Parasound Dealer or Custom Installer for more information about the SCAMP.

AC Line Cord Receptacle

The rear panel mounted IEC standard AC receptacle accepts an audiophile-grade AC cord supplied with your P/SP-1500. Plug the female end of the AC cord firmly into the AC receptacle and make sure that it is properly seated. Connect the male end directly to an AC wall outlet that is always "live" so that the P/SP-1500 retains all its memorized settings. Avoid use of an extension cord or power strip since these often degrade sound quality.
