Pre-Drilled Hole for Infrared Receivers
The PAL-380 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 easily 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-380 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
The PAL-380 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.
Three Position Midrange Adjustment
The PAL-380 midrange adjustment control allows you to adjust the midrange level from 0
dB (flat) to -3 dB or + 3 dB. If you want bring out vocals and midrange instruments and
make the speaker sound a little “forward” set the Mid switch to the +3 dB position. If you
want tone down vocals and midrange instruments and make the speaker sound a little “laid-
back” set the Mid switch to the +3 dB position.
Two Position Mid-Bass Contour Adjustment
The PAL-380 mid-bass adjustment switch allows you to attenuate the mid-bass response
from 0 dB (flat) to -3 dB. If you mounted the PAL-380 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.
