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
