Congratulations!
You are now installing a component which will dramatically
improve the performance of any distributed audio system, espe-
cially those utilizing in-wall speakers. The Architect™ Model
1100 Series are American-designed and built, “set and forget”
components which will provide a lifetime of trouble-free service
for your multi-room audio system.
The Architect™ Model 1100 Series is made by the only elec-
tronics company in the world that specializes in ampliers, equal-
izers, signal processors and audio analyzers. And the company
whose professional sound division designed and continues to sell
the most popular one-third octave real time analyzer in the world,
the SA-3050. Our passion for high quality, meticulous attention to
detail and pro sound heritage shows itself in the dozens of awards
we have won for our designs, products and service. Now, as when
we began, our greatest satisfaction is our reputation for sonic
excellence and reliability among people just like you throughout
the world.
This manual is designed to help you get everything you can
out of your new Architect amplier. So, even though you’re dying
to see it in action, please take a few minutes to slog through our
not-so-weighty prose and learn how to get the most from The
Architect power amplier. Anything as capable as this amp
deserves all the explanation it can get.

Cool Running Class H Topology - Distributed audio systems can
place terric demands on a home’s AC power. Sometimes just a little
brownout can cause an amplier to pull enough current to blow the
house circuit breaker. Even when they’re running properly, most ampli-
ers put out enough heat to make any air conditioning system sweat.
AudioControl takes care of these problems with our patented (US Pat-
ent #5,708,577) power supply regulation and Class-H amplier design.
Both of these features combine to create one of the most reliable and
efcient audio ampliers available. Higher efciency means a cooler
running amplier. The advanced power supply regulation also mini-
mizes circuit breaker-popping in-rush currents.
Built For The Long Haul – The Architect™ Model 1100 Series
are designed with durability in mind. Our exclusive LightDrive anti-
clipping protection circuitry defends The Architect™ and your speakers
against clipping, distortion, damage, and even teenage parties, even if
the party lasts all weekend. Each channel pair is independently protect-
ed so a problem in one channel will not affect the rest of the system.
Specially-Designed Equalization Controls – (Models 1160 and
1161) The equalization circuit is intended to provide a dramatic sound
improvement for “small” speakers, such as those with 6-inch and
8-inch woofers. The Architect’s 75Hz, 250Hz, 700Hz, 2500Hz and
12KHz band centers were chosen to optimize in-wall and 2-way book-
shelf speakers at critical frequencies where adjustment is most advan-
tageous. The bandwidths (or ‘Q’ as our engineering types call it) have
also been optimized for the difculties that in-wall speakers present.
This allows The Architect™ Model 1160 Series to improve the sound
of these smaller speakers better than any other equalizer.
Subsonic Filter – The Architect’s subsonic lter circuitry is a bass-
blocking 18dB/octave 38 Hz lter which protects small speakers and
improves their overall sound. It gives small woofers only those fre-
quencies they can reproduce by “chopping off” bass below 40Hz. The
woofer is protected and can do a better job of reproducing mid-bass
and higher frequencies.
Ethernet Network Compatible – (Model 1161) The power of the
Internet is built into the Architect. This internal web server provides
remote service diagnostic capabilities and enables the system integrator
to control this amplier via Ethernet.
Made in the Northwest Rainforest – The Architect™ Model
1100 Series began their existence at our factory in Mountlake Terrace,
Washington, a few miles north of Seattle. Here, we also build precision
test instruments, equalizers, analyzers and a totally awesome line of car
stereo components. AudioControl started in 1977 and has won so many
audio industry awards for design and engineering excellence that our
reception room wall is starting to sag. But enough about us, let’s start
getting the most from the audio system!

Experienced Installer’s Quick Hook-Up Guide
What follows are “Express” hook-up diagrams for profession-
als and experienced audio buffs.
Final adjustment of The Architect™ speaker optimizer con-
trols is best done with a one-third octave real time analyzer and
pink noise test signal, but it can be done by ear, especially if you
desire to emphasize certain frequencies.
One nal note: Make certain the warranty card is lled out
and mailed back to our factory. Comments received from these
warranty cards are one of the ways we keep improving our
products.
Quick
Installers Checklist
Do any zones have
more than 2 speaker
pairs? – See Page 10.
Are there any odd
shaped rooms (like
Bathrooms) or outdoor
spaces? – Try using the
Mono feature Page 5.
Do you need more than
60 watts to a speaker?
– Refer to Amplier
Bridging Appendix A.
Using the Ethernet
Control? The default IP
address for the browser
is http://192.168.0.1
Refer to Appendix B.

Front Panel
ÊStereo Speaker Equalization controls - This
array of knobs provide up to 12dB boost or cut
at 75Hz, 250Hz, 700Hz, 2500Hz and 12KHz.
After initial adjustment the only time you
would change the control settings are 1) if you
connect different speakers into the system, 2)
if (assuming the speakers aren’t built-in) you
move them signicantly, such as from a book-
shelf to oor stands, or 3) if your room acous-
tics change through addition or rearrangement
of furniture, wall or oor coverings, large hairy
dogs, etc. Note: There is a clear security cover
available as an option to cover these controls.
ËChannel Status LED’s - These dual-color
LED’s serve two purposes. First they illumi-
nate Blue when the corresponding channel is
active and operating properly. The second
function of the status LED is to turn Red if
something has caused that zone to go into
protection.

ÌProtection LED - This LED also has two
faces. In normal operation it glows Blue when
the remote power trigger is active and the
Architect is in stand-by. If the Protection LED
turns Red, then one of the internal protection
circuits have come into use. All the protection
circuits automatically reset themselves when
the problem causing the fault has been xed.
ÍPower LED - Nothing too tricky here...when
you have the Master Power switch on the back
panel turned on and the Architect is plugged
into an active AC outlet, this little Blue light
will shine forth.

ÊEthernet LAN Connection (Model 1161)
– This enables control of the Architect via
a standard 10BaseT computer network. The
internal web server of the Architect also allows
the technician to remotely monitor the status of
the amplier. See page 19 for more information.
ËBypass Switch (Models 661 and 1161) – For
diagnostics only. This button disables all the
Ethernet control functions and forces all chan-
nels on. This is useful in case there is a prob-
lem with the home automation system and you
really need some music.
ÌSignal Sense Defeat - The signal sensing
circuitry activates a zone when a signal is pres-
ent. To leave the Architect ready to play at all
times, press this switch “In” (to Defeat).
ÍBus Inputs 1 and 2 - These RCA inputs
provide two distribution busses to provide a
common signal to multiple zones. These inputs
are used in conjunction with the Bus Input
Switches on each amplier zone.
ÎSpeaker Outputs - These terminal blocks
are designed to make an installer smile. You
can unplug the blocks and connect all of the
speaker wires to them without balancing the
Architect on your lap. This also makes it very
simple to pre-wire a system.
ÏLocal Trigger Inputs – This 1⁄8” mini-jack uses
an external 12 volt trigger to switch the zone
between the bus input and the local zone input.
This is great for switching a room between the
whole-house audio signal and a local source
such as a television. The LED next to this jack
indicates when the trigger is active. The trigger
over rides signal sense.
ÐMono – This button sums (Monos) the left and
right inputs of the selected zone. This button
is active when pressed in and does not affect
any other zones. The Mono feature is also used
when you are bridging a zone.
ÑInput Level Control – This screwdriver
adjustment controls the input sensitivity of the
Architect amplier. The minimum sensitivity
(full clockwise)is 1 volt.
