<div id="overview" class="container spacer">
<p>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.</p>
<p>SLA-4 Applications:</p>
<ul>
<li>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</li>
<li>Separate mode switches allow you to bridge channels 1 and 2, or channels 3 and 4, or both channel pairs</li>
<li>Maximizes flexibility by allowing the amp to be configured for best utilization in 2, 3, or 4 channel applications</li>
<li>Designed for long-term reliability in any audio application, the SLA-4’s output is fully protected from short circuits.</li>
<li>An ultrasonic network decouples RF from the output and helps keep the amplifier stable with reactive loads</li>
<li>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</li>
<li>The SLA-4 features SmartFan, an advanced, thermal dependent fan assisted convection cooled system.</li>
<li>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</li>
<li>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.</li>
