Input - Simply connect the amplifiers + 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.) 
ating the Subwoofer SB-2 - Treat each input 
Subwoofer as an 
8R loudspeaker and wire into 
lete system accordingly (see diag.  3). (See

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 amplifiers minimum impedance load recommendation  (e.g. 8R Control@ 
speaker 
+ 4R amps 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 amplifiers 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  7011  00 volt autoformers. 
These types  of speakers need a line distribution amplifier. As  with conventional  8Q s 
ers,  simply connect the amplifiers 
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  8fl speakers, you  may connect as many 
AT speakers as youd like  to one amplifier channel 
providing that  all the speaker taps do not  add up to more than the 
amplifiers  power 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 waves  energy is reflected  and part is absorbed (see diag. 
1). 
Reflection & absorption  are dependent  on the freauencv  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 coefficient of 
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  reflec- 
tive 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).                                         
						

							
HORIZONTAL VERTICAL 
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 boundary  corner, another  t3dB ... and another  t3dB 
for a  three  boundary  corner! (see  diag. 
4). 
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 
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).                                                             
						

							
SOU 
Wind - Wind gives the illusion that a sound is coming  from 
a different  direction than it really  is. This creates  a 
re<ant 
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).  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  listeners  ear, the SPL decreases by 
6dB  (i.e. If a speakers output is  100dB SPL at  10 feet  away,  at 20 
feet away the SPL is  decreased to 94dB.) Dont forget, a 
1 OdB drop 
will  sound  half as loud.
