3.3 Ensure Proper Cooling

Please unpack and inspect your amplifier for any damage that may have occurred during transit. If damage is found, notify the transpor- tation company immediately. Only you can ini- tiate a claim for shipping damage. Crown will be happy to help. Save the shipping carton as evidence of damage for the shipper’s inspec- tion.

We also recommend that you save all packing materials so you will have them if you ever need to transport the unit. Never ship the unit without the factory pack.

YOU WILL NEED (not supplied):

Input wiring cables

Output wiring cables

Rack for mounting amplifier (or a stable surface for stacking)

WARNING: Before you start to set up your amplifier, make sure you read and observe the Important Safety Instruc- tions found at the beginning of this manual.

CAUTION: Before you begin, make sure your amplifier is disconnected from the power source, with power switch in the “off” position and all level controls turned completely down (counterclock- wise).

Use a standard 19-inch (48.3 cm) equipment rack. See Figure 3.1 for amplifier dimensions.

You may also stack amps without using a cabi- net.

NOTE: When transporting, amplifiers should be supported at both front and back.

This amplifier has been furnished with a convenient, 2-foot-long AC power cord. To meet system compliance, this cord must be plugged into a local, rack- mounted, commercial grade electrical outlet box. Extension cords are not to be used.

The K Series amplifier is convection cooled and uses no fan. If ambient temperatures are high, the TLC indicators may start to illuminate, showing that the amplifier is becoming hot.

To prevent this, space the amplifiers in the rack, allowing the top and bottom covers to act as radiators (Figure 3.2). In extreme conditions, add fans to direct air onto any surface of the amplifier.

The K Series amplifiers incorporate advanced technology such as Crown's highly efficient Class-D design, which not only reduces weight but also minimizes power consumption, making them more environmentally friendly. This efficiency allows for greater power density, meaning more power can be delivered without excessive heat generation. In addition, the K Series uses a patented "Power Factor Correction" technology, ensuring that the amplifiers perform consistently under varying load conditions, which is crucial for maintaining sound quality in professional applications.

Another key characteristic of the K Series is its robust build quality. Constructed with durable materials and featuring an efficient cooling system, these amplifiers are designed to withstand the rigors of touring and installation use. Furthermore, the K Series is equipped with comprehensive protection circuitry, including over-temperature, short circuit, and RF interference protection, guaranteeing reliable operation even in challenging environments.

The K Series also offers advanced connectivity options, with models equipped with digital signal processing capabilities. This allows users to tailor the audio output to suit specific acoustic requirements, including equalization, delays, and limiting. Additionally, the K Series is compatible with the Harman HiQnet Network, enabling remote monitoring and control via a user-friendly graphical interface.

With a combination of high output power, advanced technologies, and robust design, the Crown Audio K Series amplifiers provide exceptional performance for professionals seeking reliable, high-quality sound amplification solutions. Whether for concert tours, festivals, or permanent installations, the K Series continues to set the standard in audio amplification.
