1. Power LED – This dual color LED indi-
cates when the unit is in standby, on,
or off
Red:
The unit is in standby mode
and is ready to be turned on
via 12V triggering
Blue: The unit is on
Green: Coffee brewed
OFF: The unit is powered off
2. Protection LED – This red LED will
illuminate briefly during turn on/off
phases, and if a fault is detected in any
amplifier or the power supply (such
as overheating, over-current, or DC
offset). If a fault is detected, then the
unit will go into its protection mode to
prevent any damage to loudspeakers,
and to allow cooling.
3. Zone Status LED – This dual-color
LED indicates when the zone is in fault
mode, active, or in standby.
Red:
The zone has detected a fault,
such as a DC offset or a load
short circuit.
Blue: The zone is active
OFF: The zone is in standby

4. Zone Level LEDs – These three LEDs
light from the bottom to the top
depending on the zone's output level
(-33, -20, -10 dBFS). These LEDs can be
defeated by engaging the rear panel
switch "Disable Front LED Ladders."
5. Rack Mount Ears – The unit comes
supplied with removable rack mount
ears. These allow the unit to be rack
mounted in a standard 19" wide rack,
with a 2U height. Use standard rack
mount screws and washers to secure
the unit in a rack. The unit does not
have to be supported at the rear if the
rack is located in a fixed location.
To remove the rack ears (making the
unit 17" wide), first unplug the power
cord, and then locate and undo the
four screws securing each ear to the
side of the chassis, and remove the
ears. Replace the screws securely back
into the chassis. Do not remove any of
the other screws from the chassis or
top cover. There are hazardous voltag-
es inside the unit. Keep the rack ears in
a safe place.
Ventilation
This may be as good a time as any
to have "the talk" about ventilation.
The Architect Model 2660 features
cool-running efficient switch mode
power supplies and Class D amplifiers.
It is still a 16 channel amplifier, and
therefore requires good ventilation
to properly cool. The flow-through
5
design of the chassis allows stacking
of multiple Architect Model 2660 units
(or mix and match with our Director
Matrix M6400). When rack mounting
with equipment other than these two
AudioControl units, please leave a 1U
rack space above and below.
If the amplifier should overheat, a
thermal sensor will put it into standby
mode, allowing the heatsink to cool
down. Once the amplifier has cooled

*The protection LED also comes on for a short time during
power up or down
to a safe operating temperature,
the amplifier will reactivate. If this
occurs often, identify the cause of the
problem and take corrective action, for
example:
Provide additional ventilation
Do not install in a sealed location
with limited or no airflow
Install a fan in the rack
Make sure that the amplifiers are not
overloaded with speaker impedances
below the recommended minimum
Check that there are no short circuits
in the speaker cables or speakers.
Note: Each zone will shut off inde-
pendently when a short circuit is
detected.
