K Series Power Amplifiers

5 Advanced Features

NOTE: For detailed information about these Crown amplifier features, please consult the Crown Amplifier Application Guide, available on the Crown website at www.crownaudio.com.

5.1 Protection Systems

Your Crown amplifier provides extensive protection sys- tems, including protection against shorted outputs, open circuits, DC, mismatched loads, general overheating, high-frequency overloads and internal faults.

5.1.1 TLC

If the amplifier starts to overheat, the thermal level con- trol system will subtly and dynamically reduce the gain as needed. Transformer overheating (extremely unlikely) will result in a temporary shutdown. When the amplifier has cooled to a safe temperature, the transformer will automatically reset itself.

5.1.2 Out-of-band Filtering

An 8-Hz high-pass filter protects the amplifier and loads from subsonic frequencies. A 30 kHz low-pass filter offers protection from ultrasonic frequencies.

5.1.3 Inrush Limiting

The “soft-start” feature prevents the amplifier from draw- ing a large inrush current when it is first turned on.

5.1.4 Fuse

A fuse is provided to protect the power supplies from excess current. It is located on the back panel below the power cord.

K-Series amplifiers that are configured to use 100-120

VAC power should use the following fuses:

K2: 20-amp fuse

K1: 15-amp fuse.

K-Series amplifiers that are configured to use 200-250

VAC should use the following fuses:

K2: 10-amp fuse.

K1: 8-amp fuse.

5.2 Advanced Features

•BCA (Balanced Current Amplifier) technology allows high levels of power output without all the associated heat found in a conventional amplfifier. This highly efficient design works without using a cooling fan.

•Accurate, uncolored sound with very low distortion.

•High damping factor for tight, clean bass response.

•Advanced design for energy conservation.

•Versatile, handling a wide range of speaker impedances and outputs.

•Switchable input sensitivity.

•“Soft Start” feature prevents the amplifier from drawing large currents whenit is first turned on.

•Can be mounted in standard 19-inch (48.3-cm) rack. Uniquely molded, cast-aluminum front panel provides exceptional air circulation.

•Advanced protection circuitry guards against shorted out- puts, open circuits, DC, mismatched loads, general over- heating, high-frequency overloads and internal faults.

•Mono mode switches allow you to set up your amps/speak- ers in the configuration that best suits your needs, with combined amp inputs, combined amp outputs, or both.

•Backed by the industry’s ONLY three-year, no-fault, fully transferable warranty.

CROWN K Series specifications

Crown Audio is widely recognized for its innovative power amplifiers, and the K Series stands out as a premier solution for artists, venues, and audio engineers seeking exceptional performance and reliability. The Crown K Series amplifiers are designed to deliver high power output with remarkable efficiency, making them suitable for a wide range of applications, from live performance to installed sound systems.

One of the key features of the K Series is its sophisticated switching power supply technology. This design not only enhances power efficiency but also reduces the overall weight of the amplifiers, allowing for easier transport and setup in various environments. The use of Class D amplification ensures that the K Series maintains a high power-to-weight ratio while providing excellent sound quality. Users can expect clear, dynamic audio with minimal distortion, even at high volume levels.

The K Series is equipped with Crown’s proprietary DriveCore technology, which integrates analog and digital components into a single chip. This innovative approach streamlines the amplification process, resulting in lower operating temperatures and enhanced reliability. The amplifiers feature integrated DSP (Digital Signal Processing), allowing users to customize their audio output with adjustable EQ settings, crossover points, and limiter functions. This level of control ensures optimal performance for any sound reinforcement application.

Another notable characteristic of the K Series is its robust build quality. Constructed with a durable chassis and high-quality components, these amplifiers are designed to withstand the rigors of touring and permanent installations alike. The K Series also includes comprehensive protection circuitry to guard against overheating, short circuits, and other potentially damaging conditions, ensuring longevity and consistent operation over time.

Connectivity is simplified with the K Series, featuring a variety of input options, including balanced XLR and TRS connectors, making it easy to integrate with different audio systems. Additionally, the amplifiers can be easily bridged for applications requiring extra power, providing versatility for different sound reinforcement needs.

In summary, Crown Audio's K Series amplifiers combine cutting-edge technology, superior sound quality, and robust build design, making them a reliable choice for professionals in the audio industry. Whether for live events, installations, or studio applications, the Crown K Series delivers exceptional performance that meets the demands of modern audio environments.
