Bose 803288-1110

Overview

The Bose 803288-1110 is a four-channel PowerSpace P4300A amplifier designed to deliver 300 watts per channel while occupying just one rack unit. It supports loudspeakers with 4 or 8 ohm loads as well as distributed lines requiring 70 or 100 volt operation, all without the need for bridging or rewiring. This amplifier is ideal for environments that demand reliable, flexible sound reinforcement such as retail stores, restaurants, fitness studios, houses of worship, and conference centers.

Integration is simplified with an AmpLink port that transmits up to eight channels of uncompressed, low-latency digital audio over a single Cat 5e cable, reducing cable clutter and potential failure points. Additionally, four analog inputs and removable Euroblock connectors make installation straightforward and compatible with common commercial wiring setups.

Key features

• Delivers consistent 300 watts per channel across 4 or 8 ohm loads and 70 or 100 volt distributed speaker lines, providing versatile power options without rewiring.
• AmpLink input supports up to eight channels of digital audio via one Cat 5e cable, streamlining system design and reducing cable complexity.
• I-Share technology allows combining two amplifier channels to double output power for zones requiring extra headroom.
• Auto-standby mode conserves energy by powering down during idle periods and instantly waking when audio resumes, improving efficiency.
• Compact 1U rack chassis with front-to-back airflow ensures effective cooling even in tightly packed rack environments.
• Four analog inputs and removable Euroblock connectors facilitate quick and reliable connections with standard commercial audio wiring.
• Includes a Cat 5e cable for immediate digital audio integration, reducing setup time.

Performance and reliability

The amplifier’s design focuses on delivering reliable power with efficient cooling and energy-saving features. The front-to-back airflow system maintains optimal operating temperatures even in dense rack setups, protecting internal components. The auto-standby feature reduces power consumption during inactivity but ensures the amplifier is ready to respond instantly when audio signals return. I-Share technology provides flexibility by allowing two channels to be combined for higher power output when needed.

Ideal uses and environments

The PowerSpace P4300A is well suited to commercial and professional audio installations where space is limited but power and flexibility are essential. It fits naturally in retail environments, restaurants, fitness centers, houses of worship, and conference venues that require dependable sound reinforcement for both background music and foreground announcements. Its ability to handle both low-impedance and distributed speaker systems makes it a practical choice for integrators managing diverse audio setups.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
