Overflowing with power and precision, the ART SLA-4 4-Channel 4x140W Studio Linear Power Amplifier is a high-quality, durable, and reliable choice for any professional audio application. Whether you're working in a project studio, professional recording environment, or managing commercial sound installations, this efficient amplifier delivers the clean, robust power you need.
The SLA-4 is a true four-channel amplifier, neatly housed in a single rack-space for optimal convenience. It boasts a versatile design, allowing for easy switching between Multi-channel, Stereo, and Bridged Mono Modes. Separate mode switches enable you to bridge channels 1 and 2, channels 3 and 4, or both channel pairs, offering maximum flexibility for 2, 3, or 4 channel applications.
Designed with long-term reliability in mind, the SLA-4's output is fully protected from short circuits. An ultrasonic network decouples RF from the output, ensuring the amplifier remains stable even with reactive loads. This powerful amplifier is stable into loads as low as 2 ohms in stereo mode or 4 ohms in bridged mode, making it an ideal choice for virtually any installation application or complex system configuration.
The SLA-4 also features the SmartFan system, an advanced, thermal dependent fan-assisted convection cooled system. This intelligent system adjusts its speed based on the internal ambient temperature of the unit, ensuring optimal cooling at all times.
With 1/4-inch TRS and Euroblock balanced inputs, as well as multi-way output binding posts, the SLA-4 can be quickly and easily integrated into any system without modification. A simple to install, tamper-proof cover is included for added security.
In summary, the ART SLA-4 4-Channel 4x140W Studio Linear Power Amplifier is a powerful, high-quality, and reliable choice for any professional audio application, offering superb sound quality and long-term durability.
