Ò PFM Highpass Filter – This bass blocking lter
sets the low frequency cut-off point of the Archi-
tect. The PFM lter is 18dB per octave and the
frequency is xed at 40Hz. When this button is Out
(defeated) the channel passes full range to the zone.
Ó Bus Select Switches – These two buttons next
to each zones local input jacks selects the input
source for that amplier zone. If both buttons
are Out, the zone receives signal from the Local
Input. If the Top #1 Bus button is pressed, the
zone source is Bus Input #1. When Both Bus #1
and Bus #2 buttons are depressed, the zone source
is Input Bus #2. Whenever a Bus Input is selected,
the zone input can be remotely triggered to the lo-
cal input using the 12 volt Local Trigger input (see
#6 on previous page).
Local Inputs
- These unbalanced RCA inputs
connect to your preamplier’s outputs. Any stan-
dard line level audio signal can be connected to
these inputs.
AC Power Fuses -
The Architect is designed with
several layers of protection circuitry. These main
AC power fuses are here just in case something
really awful goes wrong. There are no internal
fuses in this amp.
Power Cord
The Architect™ draws a maximum
of 1600 watts at full power. Make certain that it
is plugged directly into the wall outlet or a power
strip with sufcient power rating. Since the Archi-
tect has remote power switching, you should plug
the unit into an AC outlet that is always active.
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.
Remote Power Control
- This three pin connector
allows you to remotely turn on the Architect. You
can either use a contact closure between the Trigger
In and the +12V output or an external 12 volt trig-
ger between the Control In and Ground terminals.
The +12 volt output is not designed to power other
pieces of equipment.
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.
