POWER
Under normal operating conditions, the Architect 900 Series
can draw up to 1600 watts of AC power. Don’t plug it into a
switched outlet on your system unless you are certain that it can
handle the power rating. Also, please don’t cut off the ground pin
on the power connector. It is an important safety feature. If you
need to plug it into a two prong outlet, use a ground adapter (and
connect the ground on it). If you have a ground noise problem, try
the ground lift switch on the rear panel.
REMOTE POWER CONTROL
The Architect has several means of power control:
1) 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.
2) 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.
3) Ethernet Control - If you have the Architect Model 961
with the Ethernet control port you have remote control over the
amplifiers power from almost anywhere in the world via the
Internet. This is also very useful on a more local sense for inte-
grating the amplifier with a home automation system via Ethernet.
4) Signal Sensing - Another level of amplifier 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 are using the
ethernet control. The power turn
on is controlled by the ethernet
