Product Description
The Samson SX1200 stereo power amplifier has been designed to provide robust, clean output with low distortion and wide dynamic range, along with the dependability demanded by professional audio engineers and installers.The convenient two rackspace design is compact, and yet there's plenty of power available, with 2 x 300 watts at 8Ω and 2 x 450 watts at 4Ω over the full frequency spectrum, from 10 Hz to 55 kHz. For mono applications, a bridged mode links both channels of the amplifiers, thus providing even more power, with a power rating of 900 watts for the SX1200 into an 8 ohm load. Input connections are made via combination connectors allowing for both balanced XLR and balanced 1/4" TRS connections. For the outputs, the SX1200 amplifier provides standard 5-way binding posts, as well as Speakon connectors. Front panel controls and displays include a 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 SX amplifiers include front panel Signal, Peak and Protection LED indicators. Like all serious power amplifiers, the SX1200's internal electronics are based around a serious power core, with oversized toroidal transformer and large extruded heat sinks. To keep the SX amplifiers running cool, their designs employ twin internal wind tunnels with forced-air cooling via two temperature-sensitive, variable speed fans, which greatly reduce 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 SX1200 is road tough with its all steel chassis, 19-inch rack mount design and convenient carry handles, so it's ready for a life of travel, or to make it's home in a fixed installation.

For many years I have been using an old Dynaco 410 amplifier to power a subwoofer in my home theatre system. I had access to a Behringer EP2000 from another system and decided to give it a try in place of my old Dynaco. It worked quite well, but the cooling fans were just a bit too noisy for a home stereo/theatre system unless you have the amplifier tucked away in an equipment closet.I also tried a Behringer A500 (which has totally silent passive cooing) and it also worked quite well, but it didn't have as much power as my old Dynaco. Both of these Behringer amplifiers sounded better than my old Dynaco so it was time to retire my old amp for a new one. I wanted more power than the A500, but less fan noise than the EP2000. Amazon.com Warehouse Deals had a Samson SX1200 available for a reduced price so I checked its specifications. This amplifier doesn't have the built-in switchable subsonic filters that the Behringer amps have but I felt I didn't need that for a home theatre subwoofer amp. What this Samson amplifier does have is variable speed cooling fans. I took a chance, hoping the fans would be quieter than the Behringer EP2000. I discovered it indeed has quieter fans, even more so than the cooling fan on my PC, so that's good enough for me. Even with the sound level cranked up, I haven't heated up the amp enough to notice much if any increase in the noise level of the fans. While playing some DVDs with very low frequency content, I observed that I could almost count the frequency cycles of the subwoofer cone moving in and out. That indicates to me that this amp is passing very low frequencies to my subwoofer. The sound from this amplifier seems to be as good as the Behringer amps, and the fan noise is less so I'm pleased with this purchase. If you don't need as much power as this Samson, (300 RMS/channel at 8 ohms, 450 RMS/channel at 4 ohms) the Behringer A500 also does a decent job, and has the additional RCA phono inputs for easy home theatre connection. The Samson SX1200 and the Behringer EP2000 have typical balanced TPS inputs, but will also accept unbalanced inputs from typical home theatre receivers if you use a TS to RCA phono adapter cable. Most all of these DJ/PA amplifiers typically have a setting switch for parallel input operation. This allows an input connected to channel one to also appear on channel two. You may also bridge the outputs of these amplifiers to power just one subwoofer of the proper impedance, if you so choose.
