AC Power
Under normal operating conditions, The Architect can draw
up to 1000 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).
Remote Power Control
The Architect has three levels 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 red 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 Power Control — This removable 3-pin remote
connector on the rear panel allows simple interfacing with external
control systems. It accepts either a contact closure or ex12
volts DC (see diagram). The two-color Protection LED on the
front panel illuminates Green to show that the remote power
control is active and The Architect
®
is in Stand-by.
3. Signal-Sense Circuit — This provides individual zone
power control. When active, it senses that an audio signal is
present on the RCA inputs, enables the power and unmutes that
zone. The zone status LEDs on the front panel light up Green
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.
Note: The channels are paired into
stereo zones (channels 1&2, 3&4,
etc.). The signal-sense control
effects both channels in a zone at
the same time even if only one input
is used.
Installation:
The Long
Version
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
Control Input pins.
Note: If you are not using the
Remote Power Control you must
connect the +12 V output to the
control input.
