Flowery Marketing Introduction
Features
When a whole-house audio system demands high levels of audio performance,
but the physical installation space is
limited, the AudioControl Architect Model
2660 is an ideal solution. Requiring only
two rack spaces, this 16 channel power
amplier produces at least 65 Watts per
channel into 8 Ohms, and 100 Watts per
channel into 4 Ohms, with all channels
driven. Extensive protection features prevent damage to your loudspeakers.
Congratulations!
You are now installing a component which
will dramatically improve the performance
of any distributed audio system, especially those utilizing in-wall, in-ceiling, and
invisible speakers.
The Architect Model 2660 16 channel
power amplier provides high levels of
power, pristine sound quality, exible
input switching, plus a number of installation-friendly features that makes it the
perfect product for performance oriented
audio systems. The Architect Model 2660
is an American-designed and built, “set
Features
Here are some of the features that make
the Architect Model 2660 a very unique
product, unlike any other amplier:
• 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 afterthought with prod-
ucts from other companies.)
• High Power Levels
There are 16 channels of 65 Watts
each into 8 Ohms, or 100 Watts into 4
Ohms. Each channel pair can also be
run in bridged mono at 175 Watts into
8 Ohms. Each high-eciency amplier is discretely made from discrete
components.
• Bussable Digital and Analog Inputs
Each zone can select either Bus A,
Bus B, or a local input. The Bus A S/
PDIF digital input uses a high resolution DAC that converts up to 192 kHz.
The digital source is available to play
in any zone. The Bus B analog input
uses a pair of RCA connectors. The
analog source is available to play in
any zone. A pair of RCA connectors
is also available as a loop output, for
example: to share the source with an-
other Architect Model 2660 amplier.
Each zone has its own local pair of
analog input connectors.
• Unparalleled Energy Eciency
Whether from the point of view of
saving electricity, or from the viewpoint of less heat in the rack, the
Architect Model 2660 amplier has
no equal. It is VERY energy ecient
during operation, and equally impressive during standby.
Introduction
and forget” component which will provide
a lifetime of trouble-free service for your
multi-room audio system.

amplier.
• LightDrive Anti-clipping
With durability in mind, AudioControl’s LightDrive anti-clipping protection defends the system against clipping, distortion, damage, and even
teenage parties. The Architect Model
2660 features the latest evolution of
LightDrive which adds a power-supply-tracking instantaneous dynamic
control to the smooth sound of the
traditional AudioControl LightDrive.
• Self Resetting Protection Features
Protection features are extensive and
include thermal, short circuit, clip-
ping, ultrasonic and DC oset among
others. If the fault is removed, the
Architect Model 2660 resets.
• Pacic Northwest Heritage
Hard to believe, but we make this
product in the USA. We are very
proud of that fact. What is more important is the care we craft in at every
step, and the extensive knowledge
we have in all aspects of the product.
Plus, we back this up with a condi-
tional ve year warranty.

Getting Started
1. Turn o power to all components before making any
connections.
2. When making connections, des-
ignate red RCA plugs as right, and
designate white, black, or grey plugs
as left. 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
know from experience that 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, consider
using an active balanced line driver
for the signals. This will provide
better noise rejection against nasty
things like hum, spikes, local talk
radio, and metaphysical paranormal
phenomena, 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.
6. If you are using the Bus A digital
input, and running higher resolution
sample rates (96 kHz - 192 kHz), use
high-quality interconnect cables.

Installation Examples
The next page shows two examples of
typical Architect Model 2660 installations.
The rst example is a home installation
with four separate zones, each playing a
dierent local analog source. Two other
zones are playing the Bus B analog source,
and one is playing the Bus A digital source.
The second example is a bar or restaurant
installation where multiple speakers in the
main seating area are playing the Bus A
digital source, and separate room zones
are playing individual local analog sources.
The versatile DIP switches of each zone
allow the selection of the local inputs, BUS
A input, and BUS B input to play in that
zone.
An Important Note about Triggering
The Architect Model 2660 master trigger
connectors (two TS 1/8” and a 3-pin block)
are used to turn on the unit or place it into
standby mode.
If no trigger voltage is present at
any of these trigger inputs, then
the unit will be in standby, with all
zones muted. If you are not using master
triggering, then you must install a short
wire link from the 12V output pin to the
trigger input pin of the 3-pin connector.
To put the unit into
standby, remove the
link.
