This is a review and detailed measurements of the Outlaw 2200 single-channel amplifier. It is on kind loan from a member. The 2200 costs US $399 plus shipping although I read that it goes on sale for less than that.
I was surprised how svelte the 2200 is given its power capability:
The diminutive size comes from "class G" implementation which varies the power supply with signal. This sharply lowers the power loss at lower power levels allowing the heatsinks to be much smaller. Despite its low "1U" height, the 2200 is heavy though courtesy of a larger pancake toroidal power transformer.
It is always great to see balanced XLR input and trigger capability on amplifiers:
In use, the 2200 was solid as a rock. It never shut down or complain and ran very cool even after full suite of tests. I was worried about recommendation to stack these from Outlaw but after testing, I think that can be done without much concern.
Amplifier Audio Measurements
As usual, we start with our dashboard of 1 kHz tone into 4 ohm load:
SINAD is supposed to be sum of distortion and noise relative to our input signal. Here, distortion is very low, approaching -105 dB. So the fact that the SINAD is just 86 dB tells us that the number is dominated by noise as you will see shortly. As it is, this is above average for some 75 amplifiers tested so far:
Here is our signal to noise ratio at 5 watts and full power:
Frequency response is a bit more limited than I like to see:
Measured power at both 4 and 8 ohms exceed outlaw specifications:
Even more power is on tap if you allow higher distortion or for momentary peaks:
Wideband spectrum analysis shows very clean output:
Those of you who are bothered by class D switching noise, should be happy to see this. Indeed I performed all of my tests without an ultrasonic filter on my Analyzer.
Thermal Stability
Performance was rock solid from cold to operating temp:
Conclusions
The Outlaw 2200 monoblocks provides solid performance, easily besting the amps you get in a typical home theater AVR and then some. Its slim packaging allows you to configure as many channels as you need without needing a lot of space. Efficiency is good but doesn't bring with it the light weight of the class D.
I am happy to recommend the Outlaw 2200 amplifier.

As always, questions, comments, recommendations, etc. are welcome.
Freezing in the garage measuring speakers. Need to get a nice supply of hot chocolate to warm me up. So please donate what you can to pay for that using : https://www.audiosciencereview.com/forum/index.php?threads/how-to-support-audio-science-review.8150/
