Crown CT 8150 - 8-Channel 125W at 4-Ohm Power Amplifier in Black Finish

The Crown CT 8150 is a versatile 8-channel amplifier designed for cinema applications, delivering 125W per channel at 4 ohms or 8 ohms. Powered by Crown's pioneering DriveCore technology, this amplifier integrates the drive stage and power output stage into a single, compact chip. This technology leverages the efficiency of Class D output stages while maintaining the superior audio characteristics of a Class AB design, ensuring high-quality audio reproduction for cinema sound systems. The CT 8150's compact 1U rack space design, combined with its robust performance and energy-efficient features, makes it ideal for cinema environments where space, power, and sound clarity are essential.

At the heart of the CT 8150 is DriveCore technology, which allows for the amplifier to deliver efficient and reliable power while maintaining clean, detailed sound. This amplifier is capable of driving 8 channels at 125W each, ensuring ample power for complex audio setups in cinema environments. The flexible input routing makes it easy to customize how audio signals are directed across the amplifier's multiple channels, providing installers with the versatility to tailor the system to their specific needs. The CT 8150 is also equipped with balanced 3-pin barrier block-type line inputs and 4-pin Phnix-type speaker outputs, ensuring reliable connections with a variety of professional audio equipment.

The CT 8150 offers advanced energy-saving modes, including Auto-Standby, Deep Sleep, and Green Mode, which help reduce power consumption during periods of inactivity. This makes it an energy-efficient solution for cinemas, where operational costs and environmental impact are important considerations. The amplifier's auxiliary port further enhances energy management by enabling external monitoring and control of power-saving features. In line with Harman's Green Edge initiative, the CT 8150 complies with environmentally-friendly practices in both its energy efficiency and manufacturing processes.

Designed with durability and reliability in mind, the Crown CT 8150 features circuit breaker protection with a reset switch, providing robust protection against electrical faults such as short circuits, overloads, and power surges. The amplifier's convection-cooled chassis eliminates the need for a cooling fan, ensuring silent operation"ideal for cinemas, where fan noise can detract from the movie-watching experience. This fanless design also increases the amplifier's reliability by reducing moving parts, which are common points of failure in traditional amplifiers with active cooling systems.

The CT 8150 is designed for seamless integration into larger audio systems, with support for mass notification and EN 54 systems, making it suitable for use in cinema installations where public address and emergency notification systems are required. The amplifier also supports fault reporting through the auxiliary port, enabling system integrators to monitor the health and status of the amplifier and quickly address any issues that may arise. With Adaptive Rail Technology, the CT 8150 delivers power on demand, adjusting its power output to match the needs of the audio signal, ensuring optimal performance and efficiency at all times.

With a signal-to-noise ratio of 110 dB, the CT 8150 delivers exceptionally clean and distortion-free audio, even at high volumes, ensuring an immersive and high-fidelity sound experience in any cinema setting. The amplifier's total harmonic distortion (THD) of less than 0.05% ensures that the sound remains accurate and free from unwanted distortion, while its frequency response of ±0.5dB ensures clear, natural sound across the entire audio spectrum. The CT 8150 also boasts excellent crosstalk isolation of over 70 dB, providing clear separation between channels, and a common mode rejection of typically greater than 70 dB, reducing unwanted noise and interference for pristine audio quality.

Weighing only 10 lbs and measuring 19 x 15.9 x 1.75 inches, the CT 8150 is lightweight and easy to install in any professional audio rack. Despite its compact size, the amplifier delivers powerful, reliable performance, making it a top choice for cinemas that require a high-quality, space-saving solution. With its robust construction, energy-saving features, and advanced audio performance, the Crown CT 8150 is a smart investment for any cinema installation seeking premium sound amplification without compromising on efficiency or durability.
