Bose Professional PowerShare PS404D Adaptable 400W Power Amplifier

Description

The PowerShare PS404D is a flexible 4-channel, 400-watt power amplifier that delivers outstanding audio performance and installation versatility. Using Bose PowerShare technology, it can distribute the total 400 W across all output channels as needed, rather than being limited to fixed wattages per channel.

The “D” model adds a Dante™ digital audio network interface, enabling integration into Dante-based audio systems. This allows both analog and digital inputs with auto-standby operation for energy efficiency.

• Total power of 400 W that can be shared across all outputs
• 4-channel Class-D design with selectable low- or high-impedance operation (4–8 Ω, 70V, 100V)
• Dante™ digital audio network interface for flexible integration (PS404D model)
• Compatible with Bose loudspeaker EQ presets for optimized performance
• Auto-standby with fast wake-up for energy savings
• Compact 1RU chassis – lightweight and rack-friendly
• Protection circuitry for safe and reliable operation
