Ultra High Power Multi-Channel Amplification
The PSX4804D delivers:
- 4 x 1200W @ 4Ω / 8Ω / 70V / 100V
- Up to 1800W per channel @ 2Ω
With a total system power of 4800W, it is designed for:
- Large hospitality venues and multi-room environments
- Retail and shopping centres
- Corporate and conference facilities
- Education campuses and public address systems
This high output ensures consistent performance across extensive speaker networks and long cable runs.
Advanced PowerShare Technology
At the core of the PSX4804D is Bose’s PowerShare technology, enabling dynamic allocation of total amplifier power across all four channels.
Unlike traditional amplifiers, this allows:
- Even or asymmetrical power distribution
- Full utilisation of available wattage
- No need to bridge channels or reduce output count
This provides maximum flexibility in system design and reduces the need for additional amplifiers in large installations.
Integrated DSP for System Optimisation
The amplifier features a powerful onboard DSP engine, providing full control over system performance without external processing.
DSP capabilities include:
- Parametric EQ and crossover configuration
- Delay alignment and filtering
- Limiting and loudspeaker protection
- Bose-certified loudspeaker presets via ControlSpace Designer
This ensures optimal sound quality, system protection, and simplified commissioning.
Dante Network Audio Integration
The PSX4804D includes integrated Dante connectivity, enabling multiple channels of low-latency digital audio over standard Ethernet infrastructure.
Key benefits include:
- Reduced analogue cabling
- Scalable system architecture
- Seamless integration with networked AV systems
This makes it ideal for modern, large-scale AV deployments.
Compatible with 100V Line and Low Impedance Systems
The PSX4804D supports a wide range of speaker configurations:
- Low impedance: 2Ω, 4Ω, 8Ω
- High impedance: 70V / 100V distributed systems
This enables:
- Distributed ceiling speaker systems
- High-output low impedance speaker setups
- Hybrid system configurations
- Seamless upgrades to existing installations
Each channel can be configured independently, providing maximum system flexibility.
Seamless Integration with Bose ControlSpace
The amplifier integrates directly with Bose ControlSpace Designer software, allowing:
- Full system configuration and tuning
- Real-time monitoring and diagnostics
- Centralised control across multiple devices
This streamlines installation workflows and simplifies long-term system management.
High Efficiency Class-D Design
Utilising advanced Class-D amplification, the PSX4804D delivers high output with reduced power consumption and heat generation.
Benefits include:
- Lower operating costs
- Reduced cooling requirements
- Compact 1U rack design
- Reliable continuous operation
A temperature-controlled fan ensures stable performance under high load conditions.
Professional Connectivity and Integration
The PSX4804D is designed for seamless integration into complex AV systems, featuring:
- Balanced analogue inputs via Euroblock
- Dante digital audio input and network control
- GPIO connections for remote control and monitoring
- Ethernet connectivity for system management
This ensures compatibility with DSP processors, mixers, and control systems.
Installation-Ready Compact Design
Despite its high output, the PSX4804D is housed in a compact 1U rack chassis, offering high power density within minimal rack space.
This makes it suitable for:
- Equipment racks in large venues
- Centralised AV control rooms
- Space-constrained installations
Ideal Applications
The Bose PowerShareX PSX4804D is widely used across high-end commercial audio environments:
- Large hospitality and leisure venues
- Retail and shopping centres
- Corporate and conference AV systems
- Education and campus-wide audio
- Houses of worship and performance spaces
Its combination of power, DSP, and network integration makes it ideal for complex, large-scale systems.
