K Series Power Amplifiers

3 Setup

3.7 Connect to AC Mains

Connect your amplifier's power cord to the AC mains power source (power outlet).

WARNING: The third prong of this con- nector (ground) is an important safety feature. Do not attempt to disable this ground connection by using an adapter or other methods.

Amplifiers don't create energy. The AC mains voltage and current must be sufficient to deliver the power you expect. You must operate your amplifier from an AC mains power source with not more than 10% variation above or below the amplifier's specified line voltage and within the specified frequency requirements (indicated on the amplifier's back panel label). If you are unsure of the output voltage of your AC mains, please consult your electrician.

3.8 Startup Procedure

Use the following procedure when first turning on your amplifier:

1. Turn down the level of your audio source.

2. Turn down the Level controls of the amplifier.

3. Turn on the Power switch. The Enable indica- tor next to the Power switch should glow.

4. Turn up the level of your audio source to an optimum level.

5. Turn up the Level controls on the amplifier until the desired loudness or power level is achieved.

6.Turn down the level of your audio source to its normal range.

If you ever need to make any wiring or installa- tion changes, don't forget to disconnect the power cord.

For help with determining your system's opti- mum gain structure (signal levels) please refer to the Crown Amplifier Application Guide, available online at www.crownaudio.com.

4 Operation

4.1 Precautions

Your amplifier is protected from internal and external faults, but you should still take the fol- lowing precautions for optimum performance and safety:

1.Before use, your amplifier must be config- ured for proper operation as described in the Setup section of this manual. Improper wiring can result in serious operating difficulties. For advanced setup techniques, consult Crown's Amplifier Application Guide available online at www.crownaudio.com.

2.Use care when making connections, select- ing signal sources and controlling the output level. The load you save may be your own!

3.Do not short the ground lead of an output cable to the input signal ground. This may form a ground loop and cause oscillations.

4.Never connect the output to a power supply, battery or power main. Electrical shock may result.

5.Tampering with the circuitry, or making unauthorized circuit changes may be hazardous and invalidates all agency listings.

6.Do not operate the amplifier with the Clip LED constantly flashing.

7.Do not overdrive the mixer, which will cause clipped signal to be sent to the amplifier. Such signals will be reproduced with extreme accu- racy, and loudspeaker damage may result.

8.Do not operate the amplifier with less than the rated load impedance. Due to the amplifier's output protection, such a configuration may result in premature clipping and speaker dam- age.

Crown is not liable for damage that results from overdriving other system components.

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.
