The SLA4 is the most versatile power amplifier from ART: a four-channel linear amp designed to drive multiple sets of studio monitors, with the versatility and volume for live and commercial applications.

It delivers 100 watts per channel at 8 ohms and 140 watts per channel at 4 ohms. Both pairs of channels can be independently bridged for up to 280 watts at 8 ohms. The SLA2 offers a wide frequency response of 10 Hz - 40 kHz (+/- 0.5 dB) with ultra-low noise and distortion to deliver the full fidelity of your source material.

Each channel has an independent volume control and status LEDs to indicate signal activity, clipping, and thermal protection. The rear panel has balanced XLR and 1/4 TRS inputs, Euroblock inputs, and binding post outputs for bare wire, banana plug, or spade connectors.

The SLA4 also incorporates our SmartFan system that adjusts the fan speed based on the internal ambient temperature for advanced cooling and quiet operation.

Whether you need to drive two pairs of monitors, two bridged output pairs for high-power stereo, or a multi-zone system, the SLA4 offers fidelity, flexibility, and durability.
