160MA specifications

Crown Audio, a leading manufacturer of professional audio equipment, has made a name for itself with its innovative amplifier designs. Among their extensive lineup, the Crown 160MA and 135MA models stand out as highly regarded solutions for various applications, particularly in commercial audio systems, installations, and even mobile setups.

The Crown 160MA is a 160-watt, 2-channel amplifier that delivers robust performance while ensuring outstanding sound quality. Designed with versatility in mind, it is well-suited for powering speakers in both small venues and larger installations where high-quality audio is required. The amplifier features a built-in mixer with three inputs, allowing users to easily connect multiple audio sources. This feature is particularly beneficial in settings such as community centers, conference rooms, and educational institutions.

On the other hand, the Crown 135MA is a slightly smaller yet equally capable 135-watt, 2-channel amplifier, designed for applications where space may be limited.

The integrated mixer also accommodates various audio inputs, simplifying connections in various environments.

Both models incorporate advanced technologies that enhance performance and reliability. They utilize Class D amplification, which not only reduces energy consumption but also minimizes heat generation, allowing for a more compact design without sacrificing output power. This makes them ideal for permanent installations where space is a constraint. Additionally, the amplifiers come equipped with comprehensive protection circuitry, safeguarding against potential overloads and thermal issues.
