ART SLA-4 overview

  • 1Description

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.

    ART SLA-4 reviews

    SLA-4 4-Channel Studio Linear Power Amplifier (100W/Channel @ 8 Ohms) is rated 4.6 out of 5 by 8.
    Rated 5 out of 5 by from Clean Amp 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.

    Rated 4 out of 5 by from Great for installations 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.

    Rated 5 out of 5 by from Good clean sound 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.

    Rated 4 out of 5 by from This is cheap and sounds AWESOME I am using this to add a little bit of oomph to my two outdoor multiroom audio zones, and this fits the bill very nicely-- four channels of 100W power in one RU is not easy to find, and it's IMPOSSIBLE to find at this pricepoint. The audio is tight and clean and LOUD-- especially when mated to an efficient speaker. I see a lot of criticism about fan noise-- I can't speak to that as this is in my central rack in the basement where I can't hear it anyway. I'm docking this a star only because it arrived in a CHEWED UP box and, SOMEHOW, the right side rack ear was BENT. I've never seen that before! Solid metal bent like paper-- I don't even know how one would do that. I bent it back (barely) with a vise grip and will be approaching B&H about some kind of money back for the cosmetic damage and my time and trouble.

    Rated 5 out of 5 by from ---------- POWER TO THE PEOPLE --------- Big things sometimes come in small packages and Art Audio's SLA4 four 100 Watt per channel power amp is no exception. Just when you thought things ain't what they used to be in the separates market place along comes this little gem . Well designed - Well Priced - Well Done Art Audio - PC LA . .

    Rated 5 out of 5 by from Great Fit 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.
    Date published: 2011-11-22
    Rated 5 out of 5 by from Exactly what I need! I have four nice speakers for my outdoor sound system and this amp powers them nicely. Great sound, very happy!

    Rated 4 out of 5 by from Work like a charm Does exactly what it says except you can't go mono to 4 outs.
