Introduction

Thank you for purchasing the PG2200 or PG 3800 power amplifier from Samson! We know you don’t like reading 

owners manuals, but you’ve just purchased one of the finest sound reinforcement power amplifiers around, and we 

want to tell you about it!  So, before you plug in, we’d like to suggest you take just a few moments out to scan these 

pages. We’ll make it as painless as possible, we promise—and, who knows, you might just pick up a tip or two. The 

Samson PG Series stereo power amplifiers have been designed to a specification we call Pure Gain Amplification. 

The PG series amplifiers provide robust, clean output with low distortion and wide dynamic range, along with the 

dependability demanded by the most professional audio engineers and installers. This manual covers both the 

PG2200 and PG3800 models. The PG series convenient 2 rack-space design is compact, and yet there’s plenty of power 

available, with 2 x 280 Watts at 8Ω, 2 x 500 Watts at 4Ω and 2 x 1000 Watts at 2Ω for the PG2200 and 2 x 560 Watts at 

8Ω, 2 x 900 Watts at 4Ω and 2 x 1800 Watts at 2Ω for the PG3800. For mono applications, a Bridge mode links both 

channels of the amplifiers, thus providing even more power, with massive mono power ratings of 1000 watts at 8Ω, 

2200 watts at 4Ω for the PG2200 and 1800 watts at 8Ω, 3800 watts at 4Ω for the PG3800. Making input connections 

is simple since the PG series’ rear panel provides both balanced XLR and balanced 1/4-inch TRS connections. For the 

outputs, the PG Series amplifiers provide standard 5-way binding posts, as well as dual Speakon™ connectors.  The 

front-panel controls and displays include a large power switch with LED indicator, as well as independent left and 

right channel input level controls. To help you set the correct operating levels, the PG series amplifiers include front 

panel Signal, Peak and Protection LED indicators. The PG series amplifiers also include onboard dynamics processing 

with a selectable Low Frequency Filter at 30 Hz to help remove stage rumble and a selectable Limiter to help protect 

your speakers and help keep your signal clean. Like all serious power amplifiers, the PG Series internal electronics are 

based around a serious power-core, with over-sized toroidal transformers and large extruded heat sinks. To keep the 

PG series amplifiers running cool, their designs employ twin internal wind tunnels with forced-air cooling via two 

temperature-sensitive, variable speed fans, which greatly reduces the chance of thermal and overheating problems. 

Multi-stage protection for power-up, over-heating, over-current, short circuit, low output impedance and DC voltage, 

assures high reliability under the most demanding situations. The PG series amps are road tough with their all steel 

chassis, 19-inch rack mount design and convenient carry handles, the PG series amplifiers are ready for a life of travel, 

or at  home in a nice fixed installation. Optimized for live sound venues, houses of worship, commercial installations, 

and for driving small and medium-sized live PA systems, the PG series amplifiers will deliver reliable power from gig-

to-gig and venue-to-venue, day in and night out. 

With proper care and adequate air circulation, your PG Series amplifier will operate trouble free for many years. We rec-

ommend you record your serial number in the space provided below for future reference.
