ART Pro Audio SLA4 Studio Linear Power Amplifier 4x100 Watts

The ART Pro Audio SLA4 is a four–channel studio power amplifier designed to drive multiple monitor sets with control and transparency. Built for mixing environments where clean, accurate amplification matters, it delivers 100 watts per channel into 8 ohms, or 140 watts into 4 ohms—enough headroom for professional studio and live monitoring without colouration. The standout spec is ultra–low noise performance exceeding 100 dB below clipping, paired with a flat frequency response spanning 10 Hz to 40 kHz (±0.5 dB), ensuring mixes translate with precision across the spectrum.

Each channel runs independent circuitry; bridge any pair to push 280 watts at 8 ohms when you need more muscle for larger rigs. Balanced XLR and 1/4" TRS inputs handle studio console outputs, whilst Euroblock connectors suit rack integration. Multi–way binding posts accept bare wire, banana plugs, or spade connectors for flexible speaker wiring. The adaptive SmartFan system throttles cooling based on thermal load, keeping operation quiet during long mixing sessions. Input sensitivity is rated at 1 V RMS for full power into 8 ohms, with input impedance of 44 kOhms balanced or 22 kOhms unbalanced—standard for clean integration with DJ mixers and audio interfaces.

Club engineers and mobile DJs running multi–zone PA systems find the SLA4's compact 19" rack form factor and four independent gains essential for driving discrete monitor arrays or bi–amped speaker pairs from a single unit. The bridging flexibility allows you to configure the amp to suit your speaker load and desired headroom on–the–fly without rewiring.
