Model P250 EQ

ARCHITECT

Features 

Here are some of the features that make 
the Architect Model P250 EQ a unique 
product, unlike any other amplifier:

•  Constant Wattage Output 

At any common speaker impedance, 
including 2 ohms, you’ll get 250 watts 
of pristine power from this fantastic 
amplifier. 

•  High Current Design 

Very demanding speaker loads can 
make most amplifiers quite unhappy, 
presenting you with continual cut 
outs or worse! The High Current Drive 
circuitry of this amplifier means it’ll 
power through speaker loads that 
most other amps simply can’t handle. 

•  Glorious IO options 

Digital, analog, SDS! Want to output 
a single source to multiple Architect 
Model P250 EQs? No problem. Loop 
outputs are available for digital or 
analog sources, allowing you to 
daisy-chain multiple amplifiers, or 
output to a multichannel amplifier. 

•  Unparalleled Energy Efficiency   

In terms of saving electricity or re-
ducing heat in the rack, the Architect 
Model P250 EQ has no equal…

•  Signal Sense Switching  

This feature will switch between the 
two main input stages - the analog 
and the digital stage. You can connect 
an analog source and a digital source 
and the unit will always switch to the 
prioritized input whenever a signal is 
sensed there.  Set the prioritization 
with the Input Priority switch. 

•  LightDrive™ Anti-clipping  

With durability in mind, 
AudioControl’s LightDrive anti-
clipping protection defends the 
system against clipping, distortion, 
damage, and even teenage parties. 
The Architect Model P250 EQ 
features the latest evolution of 
LightDrive which adds a power-
supply-tracking instantaneous 
dynamic control to the smooth 
sound of the traditional AudioControl 
LightDrive. 

•  Self Resetting Protection Features 

Protection features are extensive and 
include thermal, short circuit, clip-
ping, ultrasonic and DC offset among 
others. 

•  Pacific Northwest Heritage 

Hard to believe, but we make this 
product in the USA. We are very 
proud of that fact. What is more im-
portant is the care we craft in at every 
step, and the extensive knowledge 
we have in all aspects of the product. 
Plus, we back this up with a condi-
tional five year warranty.
