ART Pro Audio SLA4 Studio Linear Power Amplifier 4x100 Watts

The ART Pro Audio SLA4 is a four–channel power amplifier engineered to run studio monitors and live sound rigs with clean, controlled output across four independent channels. Each channel delivers 100 watts into 8 ohms or 140 watts into 4 ohms, with the ability to bridge pairs for up to 280 watts per channel at 8 ohms. That muscle matters when you're pushing multiple speaker sets or running complex monitoring arrangements without compromise.

Frequency response spans 10 Hz to 40 kHz (±0.5 dB), maintaining full fidelity from deep bass through crystalline highs. Input options include balanced XLR and quarter–inch TRS connectors, plus Euroblock sockets for flexible integration into existing rigs. Outputs use multi–way binding posts that accept bare wire, banana plugs, or spade connectors. The SmartFan cooling system ramps speed up or down with temperature, keeping noise low during extended sessions. Signal–to–noise performance exceeds 100 dB below clipping, keeping your mixes transparent and professional.

Build quality and thermal management make this amp reliable in touring scenarios and permanent studio installations alike. Compact dimensions (19 inches wide, 13.5 inches deep, 1.75 inches tall) fit standard rack configurations without eating up valuable real estate. Bridging flexibility means you can reconfigure channel assignments as your setup evolves, making it a long–term investment for engineers who expand their monitoring or speaker arrangements.
