The Architect Series
Product Highlights
Here is a list of features that are part of the Architect series from
AudioControl and make these very unique products unlike
any other ampliers.
• Superior Sound Quality; Pristine sonics happens rst in all
AudioControl designs and is not compromised by any other
feature. You often get the feeling that sound quality is an after
thought with products from other companies.
• Unparalleled Energy Eciency; Whether from the point of view
of saving electricity or from the viewpoint of less heat in the rack,
the Architect ampliers have no equal. They are VERY energy
ecient during operation and equally impressive with their
eciency during standby. During standby, these units draw less
than 1 watt of power.
• Speaker Equalization; The equalization circuit in the Architect
is intended to provide a dramatic sound improvement for “small”
speakers, such as those with 6-inch and 8-inch woofers. The
Architect’s equalization centers were chosen to optimize in-wall
and 2-way bookshelf speakers at critical frequencies where adjust-
ment is most advantageous. The bandwidths (or ‘Q’ as engineering
types call it) have been optimized for the diculties that in-wall
speakers present. This allows the Architect to improve the sound of
these smaller speakers better than any other equalizer.
• LightDrive Anti-clipping; With durability in mind, AudioControl’s
LightDrive anti-clipping protection defends the system against
clipping, distortion, damage and even teenage parties.
• Self Resetting Protection Features; Protection features are
extensive and include thermal, short circuit, clipping, ultrasonic
and DC oset among others. If the fault is removed, the Architect
amplier resets.
• Ethernet Control; (Available on Models 1281 EQ, 1261, 1681 EQ
and 1661.) Via a browser or Telnet commands you can control and
query almost all the functions. You can mute zones, change source
inputs, display protection logs and get an email if something goes
wrong. And this is only a partial list!
• Pacic Northwest Heritage; Hard to believe, but we make this
product in the USA. We are very proud of that fact. What is more
important to you is the care we craft in at every step and the exten-
sive knowledge we have in all aspects of the product. Plus, we back
this up with a ve year warranty.

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 dierent speakers into
the system, 2) if (assuming the speakers
aren’t built-in) you move them signicantly,
such as from a bookshelf to oor stands, or
3) if your room acoustics change through
addition or rearrangement of furniture, wall
or oor coverings, large hairy dogs, etc.
Channel 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 a zone to go into
protection.
 
Architect Model 1680 EQ
Architect Model 1280 EQ
Protection LED - This LED 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 engaged. The pro-
tection circuits automatically reset them-
selves when the problem causing the fault
has been xed. Should a major fault occur
(lightning strike, act of God, etc.) see the
“Troubleshooting“ section, page 19.
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.

Ethernet LAN Connection (Models 1681
EQ , 1660, 1281 EQ and 1261) – This en-
ables 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 14 for more informa-
tion.
Bypass Switch – For diagnostics only. This
button disables all the Ethernet control
functions and forces all channels on. This is
useful in case there is a problem with the
home automation system and you really
need some music.
Signal Sense Defeat – The signal sensing
circuitry activates a zone when a signal is
present. To leave the Architect ready to play
at all times, press this switch “In” (to Defeat).
Bus 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.
Speaker 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 bal-
ancing the Architect on your lap. This also
makes it very simple to pre-wire a system.
Local 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 sig-
nal 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.
Mono – This button sums (Monos) the
left and right inputs of the selected zone.
This button is active when pressed in and
does not aect any other zones. The Mono
feature is also used when you are bridging
a zone.
Input Level Controls – This screwdriver
adjustment controls the input sensitivity of
the Architect amplier.

Bus Select Switches – The switches below
each zone’s local input jacks select the input
source for that amplier zone. If the switch
is in the “Local” position, the zone receives
audio signals from the local input. If the
switch is in “Bus 1” or “Bus 2”, audio signals
come from the appropriate “Bus” inputs.
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 in-
puts connect to your preamplier’s outputs.
Any standard line level audio signal can be
connected to these inputs.
AC Power Fuse – The Architect is designed
with several layers of protection circuitry.
The main AC power fuse is here just in case
something really awful goes wrong. There
are no internal fuses in this amp.
Master Power Switch – This switch shuts
o the main AC power. Normally the only
time you need to turn the master power
switch o 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
Guided Tour
closure between the Trigger In and the
+12V output or an external 12 volt trigger
between the Control In and Ground termi-
nals. 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 oth-
er two settings for the best operation. For
your safety, the chassis is always connected
to the earth ground regardless of the switch
setting.
Remote Power control (1/8” jacks) - These
mono 1/8” jacks are wired parallel to each
other and work in conjunction with the
3-pin remote power connector. Either 1/8”
input can receive a 12-volt trigger which
will turn-on your Architect amplier. This
will then allow the unused jack to output 12
volts that can be used to turn-on a second
amplier. If your using the 3-pin connec-
tor to trigger the Architect, both of the 1/8”
jacks can provide output trigger

InstallationGuide
Audio Hook-up
If you’re an installation veteran, this may seem repetitive, but
some things can never be repeated too many times.
1. Turn o ALL components before making any connections.
2. When making connections, designate RED RCA plugs as
RIGHT and WHITE, BLACK, or GREY plugs as LEFT. In fact, this
is a good idea for ALL signal connections made in your audio
system. The key is consistency. Stick with the same color-
coding and you’ll reduce possible problems.
3. Whenever possible, keep power cords away from signal
cables to prevent induced hum. This is especially important if
you bundle the cables to keep the installation neat looking.
4. Use quality interconnect cables. We’re not going to get
into the debate about whether $100/meter cables improve
the sound, but we know from experience that really, REALLY
cheap cables can
cause a multitude
of problems. They
tend to break inside
or corrode, causing a
loss of signal or hum.
They also have poor
shielding.
5. If you need to run the RCA
audio cables more than 20
feet you should consider us-
ing an active balanced line
driver for the signals. This will
provide better noise rejection
against nasty things like hum, spikes, local talk radio, etc.
The AudioControl balanced line driver components (BLD-10,
BLR-10 and BLX-10) are an excellent way to send audio over
long distances with standard Cat-5 wiring. Check them out at
audiocontrol.com.

Remote Power Control
The Architect has several means of power control:
• Main AC Power switch - This is the master control and must
be turned ON for the Architect to function. When the main
power switch is on, the blue Power LED on the front panel lights
up. Normally the only time that you would need to turn the AC
power switch OFF is when the system is going to be unused for
an extended period.
• Remote 12 volt Power Trigger - This removable 3-pin remote
connector on the rear panel allows simple interfacing with
external control systems. It accepts either a contact closure or
external +12 volts DC. (see diagram) The two-color Protection
LED on the front panel illuminates Blue to show that the remote
power control is active.
• Mini Jack - Your Architect is equipped with two mono 1/8”
jacks which are wired parallel to each other and work in con-
junction with the 3-pin remote power connector. Either 1/8”
input can receive a 12-volt trigger which will turn-on your
Architect amplier. Additionally the unused mini jack can then
output 12 volts that can be used to turn-on secondary amplier.
If you are using the 3-pin connector to trigger the Architect,
both of the 1/8” jacks can provide output trigger.
• Ethernet Control - If you have the Architect Model 1281 EQ
or 1681 EQ with the Ethernet control port you have remote
control over the ampliers power from almost anywhere in the
world via the Internet. This is also very useful on a more local
sense for integrating the amplier with a home automation sys-
tem via Ethernet. Do not use the 12v trigger if you are control-
ling the Architech via ethernet.
• Signal Sensing - Another level of amplier control is the
Signal-Sense circuitry. This provides individual channel muting
control. When active, it senses that an audio signal is present on
the RCA inputs then enables the power and unmutes that zone.
The zone status LEDs on the front panel light up Blue when a
signal is present.
In some installations it may be desirable to defeat the signal-
sense control and leave all zones active regardless of the audio
input. To defeat the signal-sense, press in the Signal-Sense
Defeat button on the rear panel.
Installation Hint: If your
installation doesn’t require this
remote power turn-on, you must
put a short piece of wire between
the +12 V output and
the Trigger In pins.
Warning - Always
connect the safety
earth ground. If you
have an AC hum
problem, use the ground lift switch
Note: Do not use the 12 volt power
trigger if you have an ethernet
controlled unit. The power turn on
is controlled by the ethernet.

Speaker Connections
The same rule applies to the speaker wires as the RCA connec-
tions. Establish a standard connection color code and stick with
it. One conductor of the speaker wire is normally marked by a
dierent color (silver versus copper) or there is a ribbing on one
side. Typically this marked conductor is used for the positive (+)
speaker leads. Of course the really good wire has Positive and
Negative printed right onto the wire jacket.
Speaker & Wiring Impedance
Speaker impedance often is and should be straight forward.
Speakers, like other resistors, wired in parallel “show” lower
values than the individual components. In case you have for-
gotten, there is an example here for calculating speakers wired
in parallel.
Often the real world is more complicated than theory and for
speakers this is the case. An eight ohm speaker is not eight
ohms at all frequencies. Plus passive crossover networks add
their own changing conditions. What you should be aware of
and sensitive to are speakers that have signicant dips from
“nominal” values in portions of their frequency range and
speakers that are rated at unusual impedances, for example 3.5
ohms. The Architect is tolerant of lower impedance loads, how-
ever, all good designs use some margin of error.
Your choice of speaker wire gauge and the length of the runs
also aects the speaker impedance load presented to the am-
Speaker connection wiring
Speaker Wire Resistance Wire Gauge versus Run Length
Calculating Impedance
For three 8 ohm speakers wired in
parallel (pluses connected to pluses)
the impedance is
1/8 + 1/8 + 1/8 = 3/8
Then take the inverse or
8/3 = 2.66 ohms
25’ 50’ 100’ 250’ 500’
24 GA 1.3 Ω 2.6 Ω 5.1 Ω 12.8 Ω 25.7 Ω
22 GA 0.8 Ω 1.6 Ω 3.24 Ω 8.1 Ω 16.0 Ω
20 GA 0.5 Ω 1.0 Ω 2.0 Ω 5.0 Ω 10.1 Ω
18 GA 0.3 Ω 0.6 Ω 1.28 Ω 3.2 Ω 6.4 Ω
16 GA 0.2 Ω .4 Ω 0.8 Ω 2.0 Ω 4.0 Ω
14 GA 0.1 Ω .25 Ω 0.5 Ω 1.26 Ω 2.5 Ω
12 GA 0.08 Ω .16 Ω 0.32 Ω 0.8 Ω 1.6 Ω
pliers. As you can see in this
table, even fairly short speak-
er runs can have signicant
resistance if you use a smaller
wire gauge. This can be a ben-
et if you are paralleling lots
of speakers. The wire itself
acts as an impedance limiter,
since the amplier cannot
see a speaker load lower than
the resistance of the wire. The
downside of this resistance
in the wire is that you waste
some part of the total power
available to the speakers.

Bridging The Architect
To increase the output power of the Architect amplier you can
join (bridge) two channels into a single channel of 250 watts.
Accomplishing this is a simple matter. Just press the Mono
button to send the same audio signal to both channels of the
zone and then connect the speaker terminals as shown in the
diagram below.
Caution - Do not use a
speaker rated at less than
8 ohms when bridging.
In a bridged system,
each channel of the
bridged pair “sees”
one half of the speaker load.
This means that a bridged amp
driving an 8 ohm speaker is actually
operating into a 4 ohm load.

Equalizing Procedures

Equalization Procedures
(Architect Model 1680 EQ & Architect Model 1280 EQ)
Benets of Equalization
Rarely is the room layout and room decor designed to get the
most out of the audio system. In fact, almost always the oppo-
site is the case where the speaker positions and sizes are dictat-
ed by some factors which are actually contrary to good sound.
This real world situation is where equalization can provide great
benets.
Speaker positions, furniture, and general room layouts may
cause peaks in the frequency response. Fortunately these peaks
can be tamed by judicious equalization. Also, it may be that the
client has specic tastes, such as being the most interested in
hearing voices such as ball game broadcasts, and you can tailor
the sound to these tastes.
At all times, though, the laws of physics are hard to violate.
Equalization can not make terrible acoustics sound terric only
better. If the room has a tile oor and glass walls for example,
the best case results will still be pretty bad by most measures.
Further, while equalization can do wonders to help a less than
perfect speaker, nothing will make a mediocre speaker sound
fabulous. In other words, for best results, start with good speak-
ers and reasonable room acoustics, if possible.
Equalizing the System
Before proceeding on equalizing the system, it is a good idea to
make sure everything is connected and working properly. You
know how to check connections and here are some reminders
specic to the Architect, as well as the steps to equalize.
1. Turn on the system. The Power light on the front panel should
be blue .
2. Play pink noise through the system into the zones you are
going to adjust. If needed, there is a pink noise audio le at
www.audiocontrol.com. Search for “pink noise”.
3. Now grab your trusty real time analyzer (RTA) and go into the
zone you wish to adjust.
4. Place the microphone in the middle of the area of listening at
the height of the typical listeners head.
5. In general, use the equalizer controls to lower peaks in the
frequency response rst. Peaks obscure the surrounding
sounds and lowering the peaks will unleash overshadowed
sounds.
Note: For the absolutely best
results, The speaker optimizer
controls on The Architecttm
should be adjusted with a real time
analyzer such as the AudioControl
Industrial SA-3052.

Equalizing Procedures

Audio Analysis
It may take several series of adjustments since there is some
interaction between each control. We have included some
sample settings here and general descriptions of each control’s
function further on page 13 or here.
After initial adjustment the only time you would change the
control settings are 1) if you connect dierent speakers into the
system, 2) if (assuming the speakers aren’t built-in) you move
them signicantly, such as from a bookshelf to oor stands, or
3) if your room acoustics change through rearrangement of
furniture, wall or oor coverings, large hairy dogs, etc.
The following are examples of typical settings of the Architect™
Model 1280 EQ and1680 EQ Series Speaker Optimizer controls.
Naturally, the results of adjustments will vary depending on the
individual acoustic environment, the type of speakers, and the
personal preferences of the listener. These recommendations
are not concrete, they are simply good starting points.

Equalization Controls
Here is a brief introduction to each of the Speaker Equalization
control frequencies and what their aect on your music is.
75 Hz – Bass. This is at the bottom end of the frequencies which
typical in-wall and small bookshelf speakers can achieve. Even
though the Architect’s subsonic lter cuts frequencies under
40 Hz, boosting this band more than 6 dB can cause distor-
tion. Adjust this band with care. A mild boost will enhance bass
instruments such as bass guitar, kick drum, oor toms, timpani
and double bass violas.
250 Hz and 700 Hz – High and low midrange. These controls
directly aect the sound of instruments and vocals. These
bands also determine the speaker’s presence (whether the
music sounds far away or close in). Small speakers often pro-
duce too much midrange, so these controls are candidates for
being turned down slightly during your initial experimentation.
Denitely consider reducing 700 Hz if you are only using your
extension speakers for background music.
2500 Hz – Treble. Female vocals and the “edge” of instruments
such as guitars, snare drums, saxes, violins, etc. are found in
this range. If accentuated too much (by boosting this control)
sounds in the 2500 Hz range can seem harsh and fatiguing to
the ear due to excessive output by the speaker or because of
live, reective room acoustics.
12 KHz – High treble. The ne detail, texture and sheen of mu-
sic is found here. The breathiness of vocals, the sheen of cym-
bals, the high overtones of piano and strings. Actually, there’s
audible music information up to 20,000 Hz on some CD’s and
most adult’s hearing is still pretty good at 15,000 Hz. But we’ve
chosen 12,000 Hz because it provides more useful control to
compensate for room acoustics and common small-speaker
deciencies.

Model 1281 EQ and Model 1681 EQ include a built-in web server.
The server connects to the outside world using a 10 BaseT Ether-
net LAN port and the TCP/IP network protocol.
This network connection serves two purposes:
With it’s built-in web server, you can access
the Architect with any standard web browser
to check on the ampliers status and do some
simple controls. This interface is also used to
congure the network interface of the Architect.
The second protocol on the network connec-
tion is a Telnet server. This is primarily used for
integration with whole-house audio control
systems. Now let’s see how to use this interface.
To initially setup the Architect amplier and
congure the network interface you will need:
• A computer with a 10BaseT Ethernet network
adapter
• If you have an ethernet hub - A standard Eth-
ernet cable
• Also you will need to change your computer IP address to a
static address at 192.168.0.x. Anything except the default IP ad-
dress of 192.168.0.249.
Or
• If you don’t have a hub – A Crossover Ethernet cable
Once you have changed the computer’s address, connect the
computer and the Architect together through the network,
open your web browser software (Explorer, Firefox, Chrome or
Safari) and enter the following address into your browser:
Default IP address – http://192.168.0.249
You should now see the Main Operation web page of the
Architect.
From this page you have control to turn the Architect on, o
and to mute or unmute each zone. Go ahead, give it a try: Turn
on the amplier and mute a channel or two. Now watch the
front panel of the amplier change. This screen is useful for
general system diagnostics when you want to check out the
amplier operation.

Important Note: Make a note in
the front of this manual, or better
yet, on a sticker on the back of your
Architect amplier when you change
the Static IP address setting. You will
need to know that address to access
the unit. If you forget the address, you
can perform a system scan or reset
the address to the factory default
192.168.0.249. by turning o the
AC Power Switch on the back of the
amplier, hold in the reset switch (the
small hole between the LAN LEDs)
with a paper clip and then turn the
power switch back on while holding
the reset switch in for 5 seconds.
This restores all the factory default
settings.
Ethernet Connectivity
15
To remotely access the web server of the Architect from an area
outside of the local network you will need a full time connection
to the Internet (Cable, T1), a router/rewall, and more than basic
knowledge of TCP/IP network setup. Check with a professional.
The simplest means of making the web server of the Architect
accessible to the Internet is by using the Port Forwarding
feature found in most Ethernet Routers and Firewalls.
The Conguration page - Scroll to the
top of the Main User page and click the
Conguration button. This screen is
where you get to setup some options
for the network operation.
Dynamic versus Static IP Address
– This is pretty basic; a Dynamic IP
address changes every time you log
onto the network, a Static IP address
always stays the same. A good example
of a dynamic IP address is your standard Internet access. Your
computer gets a dierent IP address assigned to it every time
you connect. A network installation using Dynamic IP address
requires a dedicated device known as a DHCP (Dynamic Host
Control Protocol) server to assign the IP addresses from a pool of
available addresses as each network device logs on. For an au-
tomation system we really recommend using a Static IP address
setup. This makes it simple to always know what address to nd
a particular device, such as the Architect amplier.

Control Commands
The commands are broken into two groups: Control and Inqui-
ries. The Controls issue instructions to the Architect for power
control and channel muting; the Inquires return the status of
amplier channels, AC line voltage, the amplier temperature,
and the failure data log.
