4 x 140 Watt Studio Linear Power Amplifier

Offering superb sound quality, the ART SLA-4 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 SLA-4 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 SLA-4’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 SLA-4 features SmartFan™, 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.

They are an excellent choice when a robust amplifier is necessary to deliver the power you need for professional and project studio monitoring. ART power amplifiers may be used in a wide variety of project and professional studio environments. Self-contained in a steel and aluminum enclosure, these units are designed for many years of reliable performance. The SLA-2 Studio Linear Power Amplifier delivers 200 watts per channel (560 watts bridged mono) of clean, clear power and is housed inside a convenient single rack space! With the already stellar level of sound quality, the SLA-2’s redesigned circuitry combined with the same straightforward user interface as the SLA-1, quickly and accurately packs the additional punch you need to make your mixes clear and accurate. The SLA-2 features ART’s SmartFan™ Technology which in addition to a standard cooling fan, provides oversized convection heat sinks located on each side of the unit which silently directs heatflow outside the chassis. SmartFan's temperature controlled variable speed keeps the amp quiet and cool when performing at lower output and activates when the amp’s heatload rises. The SLA-2 also features a Euroblock connector and a tamper-proof faceplate for your fixed installations. Its long list of useful features measure up to an incredible value! Ideal for pro, project and home studios, the SLA-2 is the perfect solution for passive studio monitors.
