3.4Choose Input Wire and Connectors

Figure 3.3 shows connector pin assignments for balanced wiring, and Figure 3.4 shows connector pin assignments for unbalanced wiring.

When possible, use balanced wiring for signal input, which provides better rejection of unwanted noise and hum. For more information, refer to the Crown Amplifier Application Guide, available online at www.crownaudio.com

NOTE: Custom wiring should only be performed by qualified per- sonnel.

3.5Choose Output Wire and Connectors

Crown recommends using professionally constructed, high-

quality, two- or four-conductor, heavy gauge speaker wire and connectors. You may use terminal forks or bare wire for your output connectors (see Fig- ure 3.5). CTs amplifier terminal strips accept up to 10 AWG terminal forks which fit over a #8 screw. For best results, Crown recommends Panduit part #PV10-10LF-L or equivalent terminal fork. Screw spacing is shown in Figure 3.5.

To connect outputs, first remove the touch-proof cover plate covering the ter- minal strip by removing the screw which holds it in place.

To prevent the possibility of short-circuits, wrap or otherwise insulate exposed loudspeaker cable and connectors. Also, a touch-proof cover plate, which covers the terminal strips, is provided to help prevent short circuits. The cover plate should be reinstalled after connecting outputs.

Suggested below are guidelines to select the appropriate size of wire based on the distance from amplifier to speaker. Check with local code as this may vary.

Distance

Wire Size

up to 25 ft (7.6 m)

16 AWG

26-40 ft (7.9-12.2 m)

14 AWG

41-60 ft (12.5-18.3 m)

12 AWG

Over 60 ft (18.3 m)

10 AWG

CAUTION: Never connect the speaker return to the chassis of the amplifier, or damage to the amplifier may result.

CAUTION: Never use shielded cable for output wiring.

CTs 4200, CTs 8200 specifications

Crown Audio is recognized as a leader in professional amplification, renowned for producing power amplifiers that offer exceptional sound quality and reliability. Among their esteemed offerings, the CTs 4200 and CTs 8200 have emerged as powerful solutions for various audio applications, particularly in fixed installations and live sound reinforcement.

The Crown CTs 4200 is a versatile 4-channel power amplifier designed to deliver reliable performance in a compact form factor. It features an output power of 4200 watts at 4 ohms, making it suitable for driving multiple speaker configurations. One of the key technologies employed in the CTs 4200 is the Class D amplifier design, which ensures high efficiency while minimizing heat generation. This efficiency not only results in cleaner audio reproduction but also allows for a lighter and more portable product ideal for venue installations.

Equipped with the latest DSP (Digital Signal Processing) technology, the CTs 4200 offers comprehensive control over audio signals. Users can take advantage of features like EQ adjustments, crossover settings, and limiter controls, allowing for precise tuning to match specific acoustic environments. The front panel provides an intuitive interface for gaining access to these settings, while LED indicators provide real-time feedback on the amplifier's status.

The CTs 8200, on the other hand, elevates the output capabilities to new heights. With 8200 watts of output power at 4 ohms, this amplifier is designed for more extensive setups requiring greater amplification. It maintains the same Class D efficiency as its counterpart while offering additional channels for enhanced flexibility in setup configurations.

Both amplifiers feature a rugged construction designed to withstand the rigors of touring and installation environments, with reliable connectors and durable chassis. They also include comprehensive protection circuitry to safeguard against overloads and overheating, ensuring longevity and consistent performance.

Connectivity options further enhance their usability, providing XLR and TRS inputs along with Speakon outputs, making them compatible with a wide range of professional audio equipment. Their compatibility with Crown's intellectual property for network control opens up opportunities for remote monitoring and operation, simplifying integration into larger audio systems.

In summary, the Crown Audio CTs 4200 and CTs 8200 power amplifiers stand out for their exceptional output power, advanced DSP features, efficient Class D technology, and robust construction. Whether utilized for permanent installations or in dynamic live sound applications, these amplifiers offer unparalleled performance and versatility, solidifying Crown's legacy in professional audio amplification.
