Crown CT 4150 - 4-Channel 125W at 4-Ohm Power Amplifier in Black Finish

The Crown CT 4150 is a versatile 4-channel power amplifier specifically designed for cinema applications, providing 125W of output per channel at 4 ohms. Engineered with cutting-edge DriveCore technology, this amplifier delivers high-efficiency, pristine audio performance in a compact 1U rack space design, making it ideal for cinema environments where space is at a premium. With its robust construction, fanless convection cooling, and numerous power-saving features, the CT 4150 is not only powerful but also an energy-efficient solution that meets the demands of modern cinemas and other large venues requiring reliable sound amplification.

At the core of the CT 4150 is Crown's patented DriveCore technology, which integrates the amplifier's drive stage directly into the power output stage on a chip the size of a dime. This breakthrough design leverages the efficiency of Class D amplifier output stages, while maintaining the sonic clarity and low distortion of Class AB amplifiers. The result is a compact, efficient amplifier that provides the high-quality sound reproduction necessary for cinema applications where audio accuracy is essential. DriveCore's innovation ensures that the CT 4150 delivers clean, clear audio even under demanding conditions, making it a go-to solution for theaters and other sound-critical installations.

The amplifier's power and flexibility are further enhanced by its multiple power configuration modes, including Auto-Standby, Deep Sleep, and Green Mode, which are designed to reduce power consumption during periods of inactivity. These features allow the CT 4150 to operate efficiently, saving energy and extending the lifespan of the components. The auxiliary port allows for additional power-saving functions, such as enabling Deep Sleep mode when the amplifier is not in use. Additionally, the amplifier's convection-cooled chassis ensures quiet, reliable operation, as it eliminates the need for internal fans, making it ideal for cinema environments where low noise is crucial.

For connectivity and installation, the CT 4150 is equipped with balanced 3-pin barrier block-type/line inputs and 4-pin Phnix-type speaker outputs, which provide flexible options for integrating with various sound systems. Its flexible input routing capabilities allow users to assign input signals across the four channels, making it a versatile solution for multi-channel audio setups. Whether used in a surround sound configuration or to power individual speakers, the CT 4150 provides the flexibility and control required for sophisticated audio systems in cinemas.

The CT 4150 also incorporates advanced fault protection features to ensure reliable operation over time. It includes circuit breaker protection with a reset switch, safeguarding the amplifier from short circuits, overloads, and other electrical faults. In addition, fault reporting through the auxiliary port allows system integrators to monitor the amplifier's status, making it easier to manage and maintain large-scale cinema audio systems.

In terms of performance, the CT 4150 delivers exceptional audio quality, with a signal-to-noise ratio of 110 dB, ensuring that the sound remains clean and free from noise even at high volume levels. The amplifier boasts a low total harmonic distortion (THD) of less than 0.05%, which ensures accurate and undistorted sound reproduction across all channels. With a frequency response of ± 0.5dB, the CT 4150 maintains a flat, natural sound profile that is essential for delivering the cinematic audio experience audiences expect. Its crosstalk rating of greater than 70dB ensures excellent channel separation, while the common mode rejection of typically 70dB helps minimize interference and noise.

With its adaptive rail technology, the CT 4150 is capable of delivering power on demand, ensuring that it provides optimal performance regardless of the audio requirements at any given moment. This allows the amplifier to efficiently manage its power output, delivering only the necessary power for each audio signal while keeping energy consumption low. Compliant with Harman's Green Edge initiative, the CT 4150 is designed with environmentally-friendly practices in mind, from its energy-efficient operation to its manufacturing process.

Weighing in at just 10 lbs and measuring 19 x 15.9 x 1.75 inches, the CT 4150 is compact and lightweight, making it easy to integrate into any professional audio rack setup. Despite its small size, it delivers robust power and performance that is essential for cinema applications, providing clear and powerful sound across all channels.
