Input – Simply connect the amplifier’s “+”and “-” outputs
directly to the red (+)and black (-) input jacks on the back of the enclosure (see diag. 1).
– Since the loudspeakers have a rated
ce of 8R each, more than one speaker usually be wired to one amplifier channel (see
See “amplifier impedance load” below.)

Amplifier Impedance Load – When you connect more than one loudspeaker system to an amplifier channel, either by
twisting two wires together at the speaker location or via individual “home runs” from the speakers to the amplifier, the load impedance to the amplifier drops. To find the maximum number of 8R speakers that can be wired in parallel to each channel of your power amplifier, divide 8 by the amplifier’s minimum impedance load recommendation (e.g. 8R Control@
speaker + 4R amp’s minimum impedance = 2 speakers per channel, see diags. 2 & 3).

SerieslParallel – It is possible to utilize various serieslparallel ‘hook-up’ topologies to increase the number of loudspea
driven on an amplifier. See diag. 4 for one example of a serieslparallel hook- up topology.
Note: Mismatching the speaker impedance such that it is below the minimum impedance rating of an amplifier channel damage the amplifier and degrade performance. If the application requires more than 2 speakers per amplifier channel wired in parallel, a distributed line system should be considered. Also check your amplifier’s manual for cautions and recommendations.
Importance of Correct Polarity (“In-Phaselout-of-Phase”)- When two loudspeakers are wired with opposite polarity
(“out-of-phase”) relative to each other, the low frequencies of the loudspeakers cancel each other, even though the speak-
ers are “working hard.” Trying to correct the lack of bass with an equalizer can damage your loudspeakers — equalization
cannot correct polarity errors. Always make sure multiple speakers are connected in proper polarity. (See “Poor Low Frequency Output” in the Troubleshooting section for instructions about how to detect and correct polarity problems.)

–
Distributed Line Systems (Control “AT” models) – The Control@25AT & Control@28AT models come equipped with
in 701100 volt autoformers. These types of speakers need a line distribution amplifier. As with conventional 8 Q s ers, simply connect the amplifier’s “t”and “-” outputs directly to the red ( t ) and black (-) input jacks on the back of the enclosure. Set the autoformer tap to your desired wattage. Unlike conventional 8 f l speakers, you may connect as many
“AT” speakers as you’d like to one amplifier channel providing that all the speaker taps do not add up to more than the
amplifierspower rating (see diag. 5). (e.g. A 100 watt amplifier channel could safely drive 13 speakers set to 7.5 watts each, i.e. 13 x 7.5 = 97.5 < 100) A conservative rule-of-thumb is to try to keep the sum of the speaker loads (watts) under 314 of the power amp rating (e.g. A 100 watt amplifier channel will then drive 10 speaker set to 7.5 watts each, i.e. 10 x 7.5 = 75 watts).

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. 1). Reflection& absorption are dependent on the frea’uencv of the sound wave and the angle at which it strikes the boundary.
orption – When designing your system, note that
e and furniture absorb sound, while glass and tile t sound. The percentage of energy that a boundary orbs is often expressed by an absorption coefficientof boundarv material, where an absorlstion coefficient of
Reverberation – Reverberation 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 speakers, and play them at lower levels (see diag. 3B).

frequencies go where you point them. Simply aim the center axis of the speaker into the plane slightly above the listening area. The 90″ x 90″ horns of the Control@Contractor Series disperse the high notes by 45″ off axis in every direction. For large or unusually shaped rooms, divide the area into zones and let the horn patterns dictate the spacing between the speakers (see diag. 5)-

TYPICAL DAISY CHAIN CONFIGURATION

Boundary Loading – This is a good trick for increasing bass
without taxing the amplifier. It is also possible to make a system
sound too “muddy”, so use caution. If you move the speaker from
open space to a wall, bass notes will increase by + 3dB. If you
move it to a 2 boundarycorner, another t3dB…and another t3dB
for a three boundary corner! (see diag. 4).

TYPICAL “HOME RUN” CONFIGURATION
– Daisy Chaining It is most common, easiest, and cheapest
to run wires from the amp to a speaker, then from that
– speaker to another (see diag. 6A). Home Runs If you desire true stereo L & R from each listening position, “home runs” are best, from the amplifier directly to each speaker (see diag. 6B).

Wind – Wind gives the illusion that a sound is coming from a different direction than it really is. This creates a re&ltant propagation vector (see diag. 1). When sound propagates with the wind it tends to refract downward, and against the wind refract upwards (see diag. 2), (*refraction is the term used to describe the bending of sound).

SOU
From the speakers to our ears – Since you usually want a target
background SPL of about 70dB – 80dB to your listeners, keep in
mind the Inverse Square Law, which states that in a free field with no walls, floor, or ceiling, the intensity of sound decreases with the square of the distance. For example when you double the distance between the speaker and your listener’s ear, the SPL decreases by 6dB (i.e. If a speaker’s output is 100dB SPL at 10 feet away, at 20 feet away the SPL is decreasedto 94dB.) Don’t forget, a 1OdB drop will sound “half as loud”.

Temperature – Temperature differences also have a small
effect’on sound propagation. Hot air is less dense than cold. travels faster in a less dense medium and therefore up as air gets warmer, and slows down as air gets

It is important to understandthat just as the propagationof sound

outdoors is effected by its surroundings so is the propagation of sound

indoors. Some of these environmental factors exist in both cases,

such as reflective surfaces and absorbant materials, but there are a

few unique effects that may need to be considered. The factors

described on this Daae can cause the behavior of an outdoor installa-

tion to deviate from tjhe Inverse Square Law. Remember not all

frequencies of the propagated sound will be affected uniformly.

lHumidity – Because water vapor is lighter than air, humid is less dense than dry air and, therefore absorbs less acoustical energy than dry air particularly at frequencies above 2kHz. To labour the point, a speaker mounted on a tree in a jungle will project high frequency sound further than the same speaker mounted on a cactus in the desert (see diags. 5 & 6).

lRemove 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.

lClean 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 oilbased 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.

RODUCT CARE MAINTENANCE
Your Control Contractor system has been designed and manufactured for durability and reliable service. As with any fine product, proper maintenance and care will extend the life of your system.
You can expect your system components to perform indefinitely if you use them within their stated limits for power handling, and see that they are not abused.
Always protect the loudspeakers from over-excursion caused by strong subsonic signals (signals below 30Hz). If your amplifier has a “low cut” or “high pass” switch, engage it.
Please note that although the C23, C25 and C28 are designed to be weather resistant they are NOT WEATHERPROOF.
Insect screens have been included in the design of the low frequency vents. It may be wise to periodically check and clear any debris collected, to ensure proper operation of the vent.
A
is not unheard of for rodents to eat and destroy foam. It is recommended that the foam surrounding the SB-2 subwoofer osure be treated with a rodent repellent, especially in an installation that may be subject to the occasional rodent ation.

Problem

Causekl

Action

1. No Output.

Speaker Cable(s)

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

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.

2. Questionable or intermittent output such as crackling.

A poor connection

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.

3. Constant noise such as buzzing, hissing, or the humming sound.

A faulty electronic device in the signal chain

Since loudspeakers cannot generate these sounds b themselves, you may have a faulty electronic device the signal chain.

Poor system grounding

a Check and correct the system grounding, as required.

4. Poor low frequency output.

Out-of-Polarity Hookup between multiple speakers

When two speakers are hooked up out-of-polarity (“out of-phase”), the low frequencies cancel each other out. Try reversing the polarity of one of the speakers eithe by turning around a dual-banana plug at the amplifier by reversing the tiplsleeve leads on the jack. Whicheve
