CROWN CT 8150 - Eight-channel power amplifier, 125W @ 4Ω

CROWN CT 8150 – Eight-channel power amplifier, 125 W @ 4 Ω

The CROWN CT 8150 is an eight-channel installation amplifier delivering 125W per channel into 4Ω in a fanless 1U chassis, ideal for environments where silence and reliability are critical. Based on DriveCore™ technology, it integrates the drive and power stages into a single chip, achieving efficiencies over 90% without sacrificing the sound quality of an evolved Class AB design. Its universal power supply and convection cooling eliminate the need for maintenance and guarantee continuous operation in fixed installations.

Main features

• Flexible Input Routing: Allows any input signal to be assigned to the eight output channels.
• Convection cooling: Silent operation without fans.
• Universal Power Supply: Compatible with 100–240 VAC for global use.
• Integrated human safety: Life-safe functions suitable for evacuation systems.
• Fanless 1U Chassis: Up to 8x125W in a compact form factor.
• DriveCore™ Efficiency: > 90% efficiency, reducing consumption and dissipated heat.
• Advanced Protection: Patented feedback and limiting circuitry for 2–16 Ω loads.
• 70V/100V Output: Requires XFMR-4/8 transformer for constant voltage applications.

Product benefits

• Silent installation: Fanless, suitable for conference and broadcast environments.
• Low operating cost: Efficiency > 90% minimizes power consumption.
• Zero maintenance: Passive cooling and universal power supply with no moving parts.
• Design Flexibility: 125W output in low impedance or, with transformer, in 70V/100V.
• 24/7 Reliability: Designed for continuous operation in critical environments.

Use cases

• Distributed sound systems in shopping malls, airports, and public buildings.
• Public address and voice evacuation systems in hotels, hospitals, and auditoriums.
• Background audio in conference rooms, restaurants, and retail stores.

Frequently Asked Questions

• Is it really silent? Yes; since it doesn't use fans, its heat dissipation is achieved through passive convection.
• How do you power 70V/100V speakers? Using the XFMR-4 or XFMR-8 transformer.
• What maintenance does it require? None; since it has no moving parts, only occasional cleaning is recommended.
