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 amplier. Additionally the unused mini jack can then
output 12 volts that can be used to turn-on secondary amplier.
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 ampliers power from almost anywhere in the
world via the Internet. This is also very useful on a more local
sense for integrating the amplier 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 amplier 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.
