JWD MODEL DIN-100AT IN-WALL SPEAKER SYSTEM
INSTALLATION INSTRUCTIONS
The Model DIN-100AT is a two-way speaker system designed to be installed flush in walls or ceilings where
foreground music and voice reproduction is desired. The pivoting tweeter allows the directional high fre-
quencies to be pointed to the primary listening area for optimum sound reproduction. It may be used in
monaural 70-volt installations as well as 8-ohm stereo installations (See “Stereo Installation” below). Its
construction provides quick, simple installation as is, or may be painted to blend with any wall or ceiling decor.
Speaker Placement
Higher frequencies are more directional than lower frequencies as shown by the darker area in Figure 1.
Consequently, the sound level of the higher frequencies will be greater when the listener is directly in front
(“on axis”) of the sound source. As the position of the listener moves off axis to either side, the sound level
of the higher frequencies decrease. To compensate for this factor, the high frequency
tweeter of the DIN-100AT can be adjusted toward the primary listening area to provide best
frequency reception.
Keeping the “on-axis” concept in mind, the ideal height of the speakers should be the
listerners’ heads. For stereo, the primary listener’s heads also should be the point of a
triangle that is equal distance between the listener and the two speakers. Where this is
not practical, rotation of the pivoting tweeter should be used to direct the higher frequen-
cies in this triangular pattern. A ±3dB switch located below the tweeter also is available to
further enhance the higher frequencies if desired.
Other suggestions include:
Figure 1
A minimum mounting depth of 3
¹⁄₂" measured from the face of the wall or ceiling is needed in order to
fit properly.
6.
A thickness of
³⁄₈" to 1³⁄₈" for wall and ceiling can be accomodated.
5.
Provide at least 2" clearance between cutout and any studs or joist for mounting bracket and hard-
ware to work properly.
4.
Avoid existing electrical wires or pipes.
3.
Avoid objects that may impede the sound path between speakers and listeners.
2.
Avoid mounting speakers near a color TV set. A minimum distance of 12" from the color TV or
monitor is required, or picture distortion will occur. Also keep away from audio or video tapes.
