Pre-Drilled Hole for Infrared Receivers
The PAL-280 has a 1/2" hole in the bezel to accommodate an infrared receiver such as the Xantech Video Link model 490. The hole can be accessed by removing the rubber bushing from the rear of the bezel. If you plan to hide an infrared receiver behind the loudspeaker grille, be sure to pre-wire a three conductor control wire along with the speaker wire.
Removing the Loudspeaker Assembly from the Bezel
Gently push the lower portion of the pivoting midrange and tweeter assembly until it is at its full 15-degree downward position. This allows access for your fingers to reach inside the baffle and loudspeaker assembly and pull it away from the bezel.
Adjusting the Pivoting Midrange and Tweeter Assembly
The PAL-280 employs a pivoting midrange and tweeter assembly. You can adjust this assembly so the midrange and tweeter are pointing toward the listening position regardless of how the PAL is mounted in the wall. Gently push upper or lower portion of the pivoting midrange and tweeter assembly to aim it at the desired position.
Fine Tuning the Frequency Response of Your Loudspeakers
Three Position Treble Adjustment
High
The PAL-280 treble adjustment switch allows you to adjust the tweeter level from 0 dB (flat) to -3 dB or + 3 dB. If you are mounting the speaker in a “live” room with many reflective surfaces, you may want to attenuate the treble response and tame sibilance. If you are mounting the speaker in a room with many absorptive surfaces, you may want to boost the treble response.
Two Position Mid-Bass Contour Adjustment
Mid
Bass The PAL-280 mid-bass adjustment switch allows you to attenuate the mid-bass response from 0 dB (flat) to -3 dB. If you mounted the PAL-280 near a corner of a wall, you may notice additional boominess of the bass response. You can attenuate the mid-bass response by setting the Mid Bass switch to the -3 dB position.
