K Series Power Amplifiers

4 Operation

4.2 Front Panel Controls and

Indicators

Figure 4.1 below points out the controls, indi- cators and connectors on the front panel of the K Series amplifiers. The K1 and K2 look identi- cal except for product nameplates and fuse specifications.

A. Level Controls

The Level controls, one per channel, adjust the input attenuation from 0 dB to 100 dB.

B. Indicators

Figure 4.2 shows a closep view of the indicator

LEDs (4 per channel).

TLC: The TLC (thermal level control) indicators turn on with a dim glow a little before the amplifier needs help dissipating heat. This forewarning gives you a chance to turn on a fan or other auxiliary cooling (if available), or turn down the level controls of the amplifier. If you do neither, the amplifier will automatically

begin to protect itself with its TLC protection system by subtly and dynamically reducing the gain as needed. The TLC indicators gradually turn brighter as the TLC protection becomes greater.

Clip: Turns on when distortion becomes audi- ble in the amplifier output.

IOC: The yellow Input /Output Comparator indicators turn on when distortion reaches 0.05%, which is well before the distortion is audible.

Signal: The green Signal indicators flash dimly when a very low-level signal (as low as 10 mW) is present in the output. They flash brightly when a louder signal (at least 1 watt) is present at the output.

C. Enable Indicator

The green Enable indicator turns on when the amplifier has been turned on and has power. When first turned on, there will be a

2-second delay while the amplifier performs a

quick start-up test. Then the Enable indicator will turn on to its full brightness. If no signal is present, the Enable indicator will switch to a dimmer green.

D.Power Switch

Amplifier is on when the top half of the switch is depressed.

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.
