Introduction

Congratulations!

You are now installing a component which will dramatically

improve the performance of any distributed audio system,

especially those utilizing in-ceiling speakers. AudioControl

Architect series ampliers provide high levels of power, pristine

sound quality, unique zone equalization controls, exible input

switching plus a number of installation friendly features that

make them perfect products for performance oriented audio

systems. The Architect™ 12 and 16 channel ampliers are Amer-

ican-designed and built, “set and forget” components which will

provide a lifetime of trouble-free service for your multi-room

audio system.

The Architect™ Series is designed and manufactured by

AudioControl, the only electronics company in the world that

specializes in ampliers, equalizers, signal processors and audio

analyzers. 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 reputa-

tion for sonic excellence and reliability among people just like

you throughout the world.

This manual is designed to help users get everything they can

out of this 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 your Architect

power amplier.

Anything as capable

as this amplier

deserves all the

explanation it

can get.

Product Highlights

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.

A Guided Tour Of

The Architect Model 1280 EQ and Model 1680 EQ

Front Panel

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.

Rear Panel

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

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.
