ART SLA4 Studio Linear Amplifier

Designed for versatility, this ART 4-channel linear amp is a 1-rack-space unit that can toggle between multi-channel, stereo or various bridged modes.

Offering superb sound quality, the ART SLA4 studio linear power amplifier delivers the clean power you need for any professional audio application including project or professional studio environments or commercial sound installations.

The SLA4 is a true four-channel amplifier in a single rack-space that can be switched easily from Multi-channel, Stereo and Bridged Mono Modes. Separate mode switches allow you to bridge channels 1 and 2, or channels 3 and 4, or both channel pairs. This maximizes flexibility by allowing the amp to be configured for best utilization in 2, 3, or 4 channel applications.

Designed for long-term reliability in any audio application, the SLA4's output is fully protected from short circuits. An ultrasonic network decouples RF from the output and helps keep the amplifier stable with reactive loads. The SLA4 is stable into loads as low as 2 ohms (stereo mode) or 4 ohms (bridged mode) making it ideal for virtually any installation application or complex system configuration.

The SLA4 features SmartFan(TM), an advanced, thermal dependent fan assisted convection cooled system. The SmartFan system is dependent upon the internal ambient temperature of the unit, and runs at high or low levels depending on the amplifier's cooling needs.

1/4-inch TRS and Euroblock balanced inputs as well as multi-way output binding posts are ensure the SLA4 can be quickly and easily tied in to any system without modification. A simple to install tamper proof cover is included.

my purpose for this amp is to compare different type of monitors Studio passives monitors and Hi-fi bookshelf speakers. so far, I like what i am hearing from this amp. So you can say its for monitoring purposes lol... well, everyone have different hearing perception to what sound natural, unnatural and i won't try to describe the flats, the colors or uncolors, speaker wire length/gauge and what brand or type of passive size monitor is best. just know why and what you need this amp for and use it accordingly to what its design for. Yes it linear and so forth which is great for studio applications but again as it comes with cooling fan, expect to hear some relative low noise fan from it. I guess, its up to you how you wanna hide it or place it. all i know is i can count on this amp to give out what i put in. If you like me who have fun doing critical listening, home studio recording or collecting/experimenting with noise/sound/music or enjoy life basically, with this price range, its a good value purchase and peace of gear to have. I am at the moment contemplating either to get SLA-1 or SLA-2. faceplate is a plus.... to be able to adjust your level and safe it by just screwing the faceplate on. now, two rack space is awesome! right amount of power for my need. its simply a great peace of gear.
