  • Toroidal Transformer
  • 1/4" and Euroblock Inputs

The SLA-4 from ART is a rack mountable 4-channel power amplifier designed for studio use. It offers a wide frequency response with very low noise and distortion for quality audio output. Input is via 1/4" and Euroblock connectors, while output is via 5-way binding posts. Each channel has its own level control on the front panel.

The SLA-4 can operate in multi-channel, stereo, or bridged mode, and features a ground-lift switch to eliminate hum caused by ground loops. The unit offers full protection circuitry for short circuits, overloads, and overheating. If any faults are detected, the amplifier will disconnect the outputs and automatically return to normal operation when the fault is fixed. The SmartFan cooling system offers silent fan-assisted convection cooling to keep the system running reliably.

            I have four nice speakers for my outdoor sound system and this amp powers them nicely. Great sound, very happy!

              Rock solid amplification with four channels in a single rack space. The fan is too loud to have in a studio, but for racking them up behind the scenes they're great. Comes with a cover plate for the gain settings. A nice touch.

                  I like everything about this amplifier. I installed in a cycle room, powering thier sound system. The one space size and the four channels at 100w ea makes this a great fit. No problems at all.

                    Clean sounding amp with excellent transient response and fidelity. I'm using it in my recording studio to run 4 - 12" 3-way JBL studio monitors, and the sound is superb. The little automatic fan fires up occasionally when the temp rises, but the noise is minimal, and it only runs for a couple of minutes, then slows back down. Quality of build seems very good.

                        I used this for a church installation on a medium budget. I used two channels for the main speakers, one for a subwoofer and the last channel to drive a remote speaker. I have had no problems with it and it provided me with a really clean sound on all programmes. The security lock out panel cover is great for keeping prying fingers away from the level settings. This is one of my best buys.

                              Does exactly what it says except you can't go mono to 4 outs.
