TOA PSQ4804-DSP 4-Channel Install Power Amplifier With DSP

The TOA PSQ4804-DSP is a Powersoft Quattrocanali platform amplifier engineered specifically for permanent installation environments. It is a strong fit for integrators working in houses of worship, corporate AV, hospitality, and large-venue distributed audio systems where rack space, efficiency, and remote monitoring are primary concerns. Delivering 1200W per channel into 4 ohm, 8 ohm, 70V, and 100V loads, and 2400W bridged into 8 ohm, it handles both low-impedance loudspeaker systems and distributed 70V/100V lines without additional transformer hardware.

What separates the PSQ4804-DSP from comparable four-channel install amplifiers is its dual-supply architecture. A primary high-efficiency microprocessor-controlled power supply handles main audio output, while a dedicated secondary supply keeps DSP processing, system monitoring, and network communication active even in standby or deep-sleep modes. This means facility managers and AV technicians can poll system status, perform diagnostics, and push configuration changes without powering the amplifier into full operational mode, a meaningful advantage in managed enterprise installs. Integrated DSP removes the need for separate signal processors in the rack, tightening the signal chain and reducing points of failure.

At 1U, the PSQ4804-DSP is measurably smaller and lighter than traditional four-channel commercial amplifiers in its output class, making it well-suited for tight equipment rooms, rack-mounted furniture installations, and multi-zone systems that require several amplifier units. The combination of high output density, always-on monitoring, and native DSP makes it a practical single-box solution for demanding commercial audio installations.
