Installation Manual

Model P250 EQ

ARCHITECT

Front Panel

1.  Power LED – This dual color LED indi-

cates when the unit is in standby, on, 
or off.

Red:  The unit is in standby mode 

and is ready to be turned on 
via 12V triggering

Blue:  The unit is on
Green: Coffee brewed
OFF:  The unit is powered off 

2.  Status LED – This dual color LED will 

illuminate blue when the unit is out 
of standby and the amp is powering 
speakers or is ready to power speak-
ers. This LED will illuminate red when 
there is a short somewhere along the 
speaker wire. If you see this flicker red 
or is in a fixed red state, double check 
the speaker and speaker wire for a 
short. 

3.  Protection LED – This single color  

LED illuminates when there is a prob-
lem. After trying to play into a short 
for instance, the protection LED will 
show red and the amp will stop pro-
ducing power. Both status and power 
LEDs will turn off in this state. Turn 
off the main power, give it a minute, 
remove speaker wires and source con-
nections, then reboot. The protection 
state should be released and you can 
now troubleshoot. 

4.  Removable Feet  – Best make sure 

that if you do remove the feet, you still 
have a slight air gap between stacked 
components. 

5.  Rack Mount Ears – The unit comes 

supplied with removable rack mount 
ears. These allow the unit to be rack 
mounted in a standard 19” wide rack, 
with a 1U height. Use standard rack 
mount screws and washers to secure 
the unit in a rack. The unit does not 
have to be supported at the rear if the 
rack is located in a fixed location.

 

To remove the rack ears (making the 
unit 17” wide), first unplug the power 
cord, and then locate and undo the 
four screws securing each ear to the 
side of the chassis, and remove the 
ears. Replace the screws securely back 
into the chassis. Do not remove any of 
the other screws from the chassis or 
top cover. There are hazardous voltag-
es inside the unit. Keep the rack ears 
carefully wrapped up in a sock under 
your pillow. Make a wish and the rack 
ear fairy may come.
