The CA 20 NORMAL power amplifier

The CA 20 NORMAL power amplifier stands as a formidable solution for professionals seeking uncompromising audio power, clarity, and reliability. Engineered with advanced Class H circuitry, it offers remarkable efficiency and superior sound reproduction, making it suitable for a wide range of applications from large-scale live concerts and club sound systems to critical fixed installations and demanding studio monitoring.

Power and Performance:
This amplifier boasts significant power output across various impedance loads. For instance, it can deliver 1450 W×2 at 8Ω stereo, 2025 W×2 at 4Ω stereo, and even 2700 W×2 at 2Ω stereo. In bridged mono mode, it can produce an impressive 4050 W at 8Ω and 5400 W at 4Ω. Its frequency response spans 20 Hz to 20 kHz with minimal deviation (+/−0.5 dB or −0.3 dB), ensuring full-spectrum audio reproduction. The amplifier also features a high damping factor (often greater than 500 or 800:1), which provides superior control over speaker drivers for tight, accurate bass response. Total Harmonic Distortion (THD+N) is kept exceptionally low, typically less than 0.05% at 1 kHz and 1/4 output, ensuring pristine sound quality.

Build and Features:
Constructed within a robust 3U standard chassis, the CA 20 NORMAL is built for durability and to withstand the rigors of professional use. Its design prioritizes efficient heat dissipation through an intelligent cooling system, often employing dual variable-speed fans that draw air from front to back, preventing overheating even under sustained heavy loads.

Key features include:
Class H Circuitry: Enhances efficiency and reduces heat generation.
High Damping Factor: For precise speaker control and impactful bass.
Comprehensive Protection: Includes safeguards against DC offset, short circuits, thermal overload, VHF interference, and signal limiting, protecting both the amplifier and connected speakers.
Versatile Connectivity: Offers balanced XLR and TRS inputs, along with Speakon and binding post outputs, allowing for seamless integration into diverse audio setups.

User-Friendly Interface: Features front-panel attenuators, mode selectors (Stereo, Parallel, Bridge), and clear LED indicators for signal presence, clipping, and protection status.

Optional Crossover: Some models may include an internal crossover for 2-way bi-amplified systems.

Applications:
The CA 20 NORMAL is ideally suited for applications requiring substantial clean power, such as driving large PA systems, subwoofers, line array speakers, and for use in venues like nightclubs, concert halls, large conference rooms, and outdoor events. Its reliability and performance make it a trusted choice for professional audio engineers and system integrators.
