Y ou are now installing a component which can dramatically
improve the performance of any distributed audio system, especially those utilizing in-wall speakers. The Architect™ 900 Series
is an American-designed and built, “set and forget” component
which will provide a lifetime of trouble-free service for your multiroom audio system.
The Architect™ 900 Series is made by the only electronics
company in the world that specializes in amplifiers, equalizers,
signal processors and audio analyzers. And the company whose
professional sound division designed and sells the most popular
one-third octave real time analyzer in the world, the SA-3050.
AudioControl’s 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.
Product Highlights
This manual is designed to help you get everything you can
out of your new amplifier. So, even though you’re dying to see it
in action, please take a few minutes to slog through our not-soweighty prose and learn how to get the most from The Architect
power amplifier. Anything as capable as this amp deserves all the
explanation it can get.

Product Highlights
Cool Running - Distributed audio systems can place terrific de-
mands on a home’s AC power. Sometimes just a little brownout can
cause an amplifier to pull enough current to blow the house circuit
breaker. Even when they’re running properly, most amplifiers put out
enough heat to make any air conditioning system sweat. AudioControl
takes care of these problems with our patented (US Patent #5,708,577)
power supply regulation and Class-H amplifier design. Both of these
features combine to create one of the most reliable and efficient audio
amplifiers available. Higher efficiency means a cooler running amplifier .
The advanced power supply regulation also minimizes circuit breakerpopping in-rush currents.
Built For The Long Haul – The Architect™ 900 Series has been
designed with durability in mind. The Lightdrive 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 protected so a problem in one
channel will not affect the rest of the system.
Specially-Designed Equalization Controls – (Model 960 and
Model 961) The Architect™ 900 Series is intended to provide a dramatic sound improvement for “small” speakers, such as those with 6inch and 8-inch woofers. The Architect’s 75Hz, 250Hz, 700Hz, 2500Hz
and 12KHz band centers were chosen to optimize in-wall and 2-way
bookshelf speakers at critical frequencies where adjustment is most
advantageous. The bandwidths (or ‘Q’ as our engineering types call it)
have also been optimized for the difficulties that in-wall speakers
present. This allows The Architect™ 900 Series to improve the sound
of these smaller speakers better than any other equalizer.
PFM Subsonic Filter – The Architect’s Programmable Frequency
Match (PFM) circuitry is a bass-blocking 40 Hz filter which protects
small speakers and improves their overall sound. It gives small woofers
only those frequencies they can use by “chopping off” bass below 40Hz.
The woofer is protected and can do a better job of reproducing midbass and higher frequencies.
Ethernet Network Compatible – ( Model 961) 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 amplifier via Ethernet.
Made in the Northwest Rainforest – The Architect™ 900 Series
began its existence at our factory in Mountlake T errace, 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!

Stereo 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
significantly, such as from a bookshelf to floor
stands, or 3) if your room acoustics change
through addition or rearrangement of furniture,
wall or floor coverings, large hairy dogs, etc.
Channel Status LED’s - These dual-color
LED’s serve two purposes. First they illuminate
Blue when the corresponding channel is active.
The second function of the status LED is to
turn Red if something has caused that zone to
go into protection.
Protection 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 fixed.
Power 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.

PFM Highpass Filter – This bass blocking filter
sets the low frequency cut-off point of the Architect. The PFM filter is 18dB per octave and the
frequency is fixed at 40Hz. When this button is
Out (defeated) the channel passes full range to the
zone.
Bus Select Switches – These two buttons next to
each zones local input jacks selects the input
source for that amplifier zone. If both buttons are
Out, the zone receives signal from the Local Input.
If the T op #1 Bus button is pressed, the zone
source is Bus Input #1. When Both Bus #1 and
Bus #2 buttons are depressed, the zone source is
Input Bus #2. Whenever a Bus Input is selected,
the zone input can be remotely triggered to the
local input using the 12 volt Local Trigger input
(see #6 on previous page).
Local Inputs - These unbalanced RCA inputs
connect to your preamplifier’s outputs. Any
standard line level audio signal can be connected to
these inputs.
AC Power Fuses - The Architect is designed with
several layers of protection circuitry . These main
AC power fuses are here just in case something
really awful goes wrong. There are no internal
fuses in this amp.
Power Cord The Architect™ draws a maximum
of 1600 watts at full power. Make certain that it is
plugged directly into the wall outlet or a power
strip with sufficient power rating. Since the Architect has remote power switching, you should plug
the unit into an AC outlet that is always active.
Master Power Switch - This switch shuts off the
main AC power. Normally the only time you need to
turn the master power switch off is if the system is
going to be shut down for an extended period of time.
Remote Power Control - This three pin connector
allows you to remotely turn on the Architect. You
can either use a contact closure between the TriggerIn and the +12V output or an external 12 volt trigger
between the Control In and Ground terminals. The
+12 volt output is not designed to power other pieces
of equipment.
Ground Lift Switch – This switch selects the level
of isolation between the audio signal ground and
your AC earth ground. In normal operation this
switch should be in the Ground position, but if you
run into trouble with an AC ground hum, try the
other two settings for the best operation. For your
safety , the chassis is always connected to the earth
ground regardless of the switch setting.

Hooking Up Your System
What you’ll need:
1.The Architect™ 900 Series Amplifier.
2.RCA audio hook-up cables.
3.Small blade screwdriver for terminal blocks
4.(Optional) A balanced line driver (of course we recommend the AudioControl BLD-10 and BLR-10) if you are
going to mount the Architect more than 20 feet from the
preamp.
5.Enough speaker wire to reach all of your speakers.
6.Multi-zone audio controller, receiver , or preamplifier .
7.Although you can set the speaker optimization controls
by ear, a real-time audio analyzer such as the
AudioControl Industrial SA-3052 is very helpful.
