Ê
Remote Power Control - This three pin connec-
tor allows you to remotely turn on the Architect.
You can either use a contact closure between the
Control In and the +12V output or an external 12
volt trigger between the Control In and Ground
terminals. The +12 volt output is not designed to
power other pieces of equipment. It is a current
limited output for switching the Architect only.
Ë
Signal Sense Defeat - The signal sensing cir-
cuitry activates a zone approximately 0.5 second
after an audio signal is present on the Input RCA
jacks. To defeat this function and leave the
Architect ready to play at all times, press this
switch in to the recessed (Defeat) position.
Ì
Inputs - These unbalanced RCA inputs connect
to your preamplifier’s outputs. Any standard line
level audio signal can be connected to these
inputs.
Í
Thru Outputs - These unbalanced RCA outputs
send a buffered audio output to daisy-chain
multiple amplifiers together.
Î
Input Level Control - This screwdriver adjust-
ment controls the input sensitivity of the Architect
amplifier. The sensitivity is variable from 0-1
volt.
Ï
PFM Highpass Filter - This bass blocking filter
adjustment sets the low frequency cut-off point of
the Architect. The PFM features an 18dB per
octave slope and the filter frequency is adjustable
from 20Hz to 80Hz.
Ð
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 balancing the Architect on your lap.
This also makes it very simple to pre-wire a system
without ever taking the Architect out to the installa-
tion site. The two output blocks are paralleled to
simplify connection to multiple speaker zones. The
speaker connector blocks will accept up to 12 awg
wire.
An optional set of 5-way binding posts are available
for installers that prefer this type of speaker connec-
tion (The Architect Model 105 and Model 205).
Ñ
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 other two
settings for the best operation. For your safety, the
chassis is always connected to the earth ground
regardless of the switch setting.
Ò
AC Power Fuse - The Architect is designed with
several layers of protection circuitry. This power fuse
is here just in case something really awful goes
wrong.
Ó
Master Power Switch - This switch shuts off the
main AC power. Normally the only time you need to
turn the master power switch off is if the system is
going to be shut down for an extended period of time.
Power Cord - The Architect
tm
draws approximately
500 watts at full power. Make certain that it is
plugged directly into the wall outlet or a power strip
with sufficient power rating. Since the Architect has
remote power switching, you can plug the unit into an
outlet that is always active.
