Center Channel Speaker Selector

8 P/DD-1500 Owner's Manual

Set this rear panel switch to accommodate the bass capabilities of your center channel speaker. Following are descriptions of the recommended center channel switch settings based upon the center speaker you will be using:

No Speaker, Phantom Mode

Select the No Speaker 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. In some systems a phantom center channel may provide a wider listening "sweet spot".

Small Speaker, Bass Filter On

Select the Small Speaker position for typical sized center channel speakers. In this position, the P/DD- 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 typical smaller center channel loudspeakers.

Large Speaker, Bass Filter Off

Select the Large Speaker 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/DD-1500 routes the entire audio bandwidth

(20 Hz - 20 kHz) to the center channel output.

Internal LFE Level Switch

There is an internal two position DIP switch to select the output level of the LFE channel to accommodate the host processor used with your P/DD-1500. You can select between the factory setting of 3 V or 5.4 V. During setup, if you are not getting enough output level from the subwoofer channel, set this position to the 5.4 V position. Conversely, if you discover that the LFE channel is easily overloaded, set this switch to the 3 V position. To access this switch, you will need to remove the cover panel. Be sure the power is removed from the wall outlet before you reset this switch.
