The Cloud CA8125 is a high-capacity 8-channel Class-D power amplifier engineered for large-scale commercial audio installations requiring flexible zoning, efficient power distribution, and reliable long-term operation. Delivering 8 x 125W of output power with a total system output of 1000W, it provides a scalable amplification platform for multi-zone environments. As part of Cloud’s established CA Series, the CA8125 is designed to streamline system architecture by consolidating multiple amplifier channels into a single unit, making it ideal for complex installations across hospitality, retail, education, and commercial sectors. Eight Channels for Large Multi-Zone Systems The CA8125 delivers 125W per channel across eight independent outputs, enabling multiple zones or speaker circuits to be powered from a single amplifier. This makes it particularly suitable for: Large hospitality venues with multiple audio areas Retail stores and shopping centres Corporate buildings and office spaces Education campuses and public buildings Warehouses and industrial environments By integrating eight channels into one unit, the CA8125 significantly reduces rack space and simplifies system design. Compatible with 100V Line and Low Impedance Systems The CA8125 supports both high impedance (70V/100V line) and low impedance (≥4Ω) loudspeaker systems, selectable per channel via rear-panel configuration. This enables: Distributed ceiling speaker systems Wall-mounted loudspeaker installations Hybrid system designs Seamless upgrades to existing systems This dual compatibility ensures maximum flexibility across a wide range of commercial applications. Intelligent Power Sharing for Efficient Output Distribution A key feature of the CA8125 is its intelligent power-sharing capability. In 100V line mode, the amplifier’s total 1000W output can be dynamically distributed across channel groups, allowing power to be allocated where it is most needed. This provides: Efficient use of available amplifier power Flexibility for uneven speaker loads across zones Reduced requirement for additional amplification This is particularly beneficial in large installations with varied zone requirements. High Efficiency Class-D Design Utilising advanced Class-D technology, the CA8125 delivers high output with reduced power consumption and heat generation. Benefits include: Lower operating costs Reduced cooling requirements Compact and lightweight design Reliable continuous operation The transformerless output stage further improves efficiency while maintaining performance. Energy Saving with Automatic Power Down The CA8125 includes an Automatic Power Down (APD) feature, reducing power consumption to less than 2.5W when idle. The amplifier automatically resumes operation when an audio signal is detected. A remote standby/wake function is also included, enabling integration with control systems for improved energy management. Professional Connectivity and Configuration The amplifier is designed for seamless integration into commercial AV systems, featuring: Balanced line-level inputs Per-channel gain controls for precise level adjustment Rear-panel DIP switches for routing and configuration Optional Dante interface compatibility for networked audio This ensures compatibility with mixers, DSP processors, and control systems in both standalone and networked environments. Built for Reliability in Continuous Operation The CA8125 includes a comprehensive protection suite to ensure stable and long-term performance: Thermal protection and monitoring Overcurrent protection DC offset detection Switch-on delay for speaker protection Variable-speed forced-air cooling These features ensure reliable operation in demanding commercial environments. Installation-Ready 2U Rack Design Housed in a standard 2U 19-inch rack format, the CA8125 is designed for straightforward installation into AV racks and equipment cabinets. Its robust construction and front-panel status indicators allow for easy monitoring and system management. Ideal Applications The Cloud CA8125 is widely deployed across professional audio installations: Large multi-zone background music systems Hospitality venues and restaurants Retail and shopping centres Corporate and office environments Education and campus-wide audio Public address and paging systems Its eight-channel architecture makes it particularly suited to larger and more complex audio systems.

The Bose PowerShareX PSX1204D is a high-performance 4-channel installation amplifier engineered for modern commercial audio systems requiring flexibility, network integration, and efficient power distribution. Delivering a total of 1200 watts across four channels, this intelligent amplifier combines onboard DSP, Dante networking, and Bose’s advanced PowerShare technology to streamline system design and maximise performance in real-world environments. Designed specifically for professional AV integrators, the PSX1204D enables seamless deployment across hospitality venues, education facilities, retail spaces, corporate environments, and houses of worship, where multi-zone audio and system scalability are critical. At the core of the amplifier is Bose’s PowerShare technology, allowing total amplifier power to be dynamically distributed across outputs. This removes the need for channel bridging and ensures optimal power delivery regardless of speaker configuration, significantly improving system efficiency and flexibility during installation. Integrated DSP provides direct access to Bose Professional loudspeaker presets via ControlSpace Designer software, enabling rapid system configuration, loudspeaker optimisation, and ongoing monitoring from a single interface. This reduces commissioning time while ensuring consistent, protected system performance across all zones. The inclusion of built-in Dante networking allows up to four channels of digital audio to be received over standard network infrastructure, eliminating the need for additional interface cards and simplifying system architecture in larger or distributed installations. Alongside this, four analogue inputs provide flexibility for local sources such as media players, microphones, or mixers. The PSX1204D supports both low impedance (2, 4, 8 ohms) and high impedance (70V/100V) speaker systems, making it suitable for everything from background music systems in cafés and retail stores to more demanding multi-zone audio installations in schools, bars, and commercial venues. For system integrators and facility managers, network monitoring capabilities provide real-time performance data, enabling proactive maintenance and reducing downtime. GPIO connections further enhance system control, allowing integration with external control systems for volume adjustment, muting, or system triggering. Physically, the amplifier features a compact 1U rack design, making it ideal for installation within comms racks, plant rooms, or under-counter AV setups where space is limited but performance cannot be compromised. Typical system applications include background music systems for restaurants and retail, multi-zone audio in offices and warehouses, school hall and classroom audio systems, and integrated AV solutions in hospitality and leisure environments. The combination of Dante networking and onboard DSP makes it particularly effective in scalable, future-proofed AV infrastructures. For integrators working within the Bose ecosystem, the PSX1204D offers seamless compatibility with Bose loudspeakers, DSP processors, and control interfaces, ensuring consistent system design and simplified commissioning workflows. This product is priced on application and ordered directly from the manufacturer, ensuring the correct specification and system compatibility for your project.
