Importance of Correct Polarity ("In-Phaselout-of-Phase")

("out-of-phase") relative to each other, the low frequencies of the loudspeakers cancel each other, even though the speak-

because of differences in the acoustical setting. Since an enclosed room
presents acoustical boundaries (walls, floors

&

ceilings), sound indoors
exhibits quite complex behavior. Each time a sound wave strikes a boundary,
part of the wave's energy is reflected and part is absorbed (see diag.

is the reflected sound
waves continuing to bounce between the boundaries, losing
energy with each reflection. When sound strikes the reflec­tive boundaries of a room, after a time the room is filled with
random reflected sound waves. Music and speech become
unintelligible (see diag. 3A). To minimize reverberation in a
highly reverberant room, it is advisable to install

more

Simply aim the center axis of the

It is important to understand that just as the propagation of sound
outdoors is effected by its surroundings so is the propagation of sound
indoors. Some of these environmental factors exist in both cases,

Humidity - Because water vapor is lighter than air, humid

Painting the Speakers

-

The polystyrene speaker enclosures of the Controls 23,
Control@ 25,

&

Control@ 28 can be painted to match almost
any decor. The vinyl skin of the Controls SB-2 subwoofer can
also be painted.

l

Remove the grilles. Mask the woofers, tweeters, & ports on
the front, and the wire terminals on the back, being careful
that no tape comes in direct contact with the drivers.

l

Clean the enclosures with a light solvent such as mineral
spirits by rubbing the components with a lightly dampened
cloth. Do not, however, use abrasives such as sandpaper or
steel wool on the enclosures. Nor should you use gasoline
kerosene, acetone,

MEK,

paint thinner, harsh detergents o
other chemicals. Use of these cleaners may result in perm
nent damage to the enclosures.

After cleaning, apply two or more thin coats of either latex or
oil-based paints. Latex paints will adhere better if an oil-

based primer is used first. Application can be by rolling,
brushing, or spraying.

The grilles require masking of the logo plug, then spray

painting. If the grill is rolled or brush painted, the mesh may

become clogged with paint, and poor sound quality may

result.

Action

Replace the cable(s) connecting the loudspeaker system
and amplifier.

Make sure the amplifier channel is being fed an input

signal (preferably via a "signal input" indicator on th
amp).

Check that the amplifier channel's volume control is
turned up.

Connect the speaker and cable which had no output
another amplifier channel, making sure an input sign
fed to the new amp channel. If you then get output, th

problem was the amplifier channel. If not, then the

problem may be in the cable or speaker.
Check all cabling for proper connector contact since a

bad connection can result in intermittent contact or
dramatically increased resistance which, in turn, can
cause reduced output or noises unrelated to the signal.
