Overview

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.

SLA-4 Applications:

• 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
• 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
• SLA-4 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.
