ART SLA 1 - Studio Linear Amplifier 2 x 130 W

The SLA1 is a two-channel linear power amplifier designed for passive studio monitors. It delivers 100 watts per channel at 8 ohms and 130 watts per channel at 4 ohms. It can also be bridged for up to 260 watts into a single 8 ohm load. The SLA1 offers a wide and linear frequency response of 10 Hz to 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, and binding post outputs for bare wire, banana plug, or spade connectors. The SLA1 also incorporates our SmartFan system that adjusts the fan speed based on the internal ambient temperature for advanced cooling and quiet operation.

Ground Lift Switch

This switch is used to disconnect the internal ground signal from the chassis (case) ground. This may be used to reduce 50Hz noise (hum or buzz). Normally you would ground the chassis, for best shielding. When the SLA-1 is mounted in a grounded rack of equipment, the ground to the case may be lifted to prevent multiple ground paths, which may cause a ground loop to occur.

Inputs

The SLA-1 has two styles of input connections: XLR and 1⁄4”. Use these connections to connect the output signal from a mixer, preamplifier, crossover, or EQ to the amplifier. The balanced XLR connection is recommended for cable runs longer than 20 feet. For cable runs under 20 feet, the 1⁄4” option may be preferable.
You may also use the two different types of input cables to jump a parallel connection to another amp. For example: connect an XLR cable to the input of channel one, then connect a 1⁄4” cable to the input jack of channel one and jump that cable to the input of another amp.
