Audac Eight-channel amplifier CEP803 (2SA0816) — 8×100W output, 8-channel professional power amplifier

The Audac Eight-channel amplifier CEP803 is a professional multi-channel power amplifier that provides eight balanced outputs, each rated at 100 W. Designed for distributed audio installations and multi-zone sound systems, this compact rack-mountable unit delivers stable power for background music, paging and venue sound reinforcement. The amplifier is engineered for integration into AV systems where space-efficient multi-channel amplification and reliable continuous performance are required.

Advantages

The CEP803 offers eight independent channels in a single chassis, reducing rack space and simplifying cabling compared with multiple single-channel amplifiers. Each channel delivers consistent 100 W output, allowing uniform audio coverage across several zones. The unit's professional design supports integration into centralized control systems and provides stable thermal and electrical performance for prolonged operation in commercial environments.

Suitable for

• Multi-zone background music systems in retail, hospitality and office environments
• Paging and voice evacuation systems in schools, hospitals and public buildings
• Small to medium-sized venue sound reinforcement with independent zone control
• AV racks where compact multi-channel amplification is required

Key specifications

• Number of channels: 8 independent channels
• Power per channel: 100 W continuous output
• Form factor: Rack-mountable multi-channel amplifier
• Intended use: Distributed audio and multi-zone installations
• Cooling: Built for stable thermal performance under continuous load

How to use

Install the amplifier in a standard 19-inch equipment rack using appropriate mounting hardware and ventilation clearance. Connect audio sources and zone controllers to the inputs and wire each speaker line to the corresponding channel outputs, observing correct impedances and wiring practices. Configure gain and input routing via the front- or rear-panel controls (as provided) to balance levels between zones. Ensure the unit is powered from a stable AC supply and that cooling pathways are not obstructed.

Usage recommendations

For reliable long-term operation, use the amplifier within its rated output per channel and match speaker impedances to recommended values. Allow adequate ventilation space in the rack, avoid stacking heat-generating equipment directly above, and plan speaker cabling runs to minimize impedance losses. For paging applications, integrate with a dedicated microphone input and zone control system to ensure clear announcements and priority routing when required.
