M Series Power Amplifiers

4Advanced Features and Options

4.3Optional Barrier Block Outputs

If you prefer, the 5-way binding post outputs on your M-Series amplifier can be replaced with model CEAS1 barrier block outputs (see Figure 4.3). You can order your M-Series amplifier with barrier block outputs factory-installed on new amplifiers or they can be added to existing M-Series amplifiers by an authorized Crown Service Center. Please contact Crown Technical Support or your local Crown Service Center for more information on this option.

4.4 Tamper-Resistant Hole Plugs

Your M-Series amplifier comes with a set of tamper-resistant hole plugs, which allow you to “protect” the level controls against unautho- rized adjustment. To use, simply pull off the control knobs from the front of the amp, and

slip the hole plugs into place (see Figure 4.4). The plugs should slide easily into position, without forcing. Once in place, the plugs will help to avoid most accidental or intentional tampering (some situations may require addi- tional security measures).

To remove the hole plugs, simply pry the plug away from the amplifier case using a small, flat- blade screwdriver. To help to ensure adequate security, the plugs have been designed to be more difficult to remove than to place into posi- tion. If necessary, additional hole plugs can be purchased separately from Crown’s Parts Department (Part # 103234-1).

Store your knobs in a safe location should you need to make level adjustments in the future.

4.5Optional 0.775-V Input Sensi- tivity Setting

The M-Series amplifier also provides an optional 0.775-V input sensitivity setting. If you determine your application requires this sensi- tivity setting, please contact Crown Technical Support for more information.

M Series specifications

Crown Audio's M Series amplifiers are a renowned collection in the realm of professional audio equipment, recognized for their reliability, performance, and innovation. Designed specifically for commercial installations, the M Series provides powerful amplification with exceptional audio quality, making it a prime choice for venues such as auditoriums, churches, and theaters.

One of the standout features of the M Series is its high-efficiency Class D topology. This design not only reduces power consumption but also minimizes heat generation, which is crucial for long-term reliability and performance in demanding environments. The amplifiers are capable of delivering high output power while maintaining low distortion, ensuring that the audio experience remains clear and robust, even at high volumes.

The M Series amplifiers are equipped with a range of power options, ensuring that users can find a model that suits their specific needs. The lineup typically includes models ranging from 2-channel to 4-channel configurations, with power ratings suitable for various applications. This versatility allows for flexible setups, whether powering large PA systems or smaller setups for more intimate settings.

Integration with control systems is effortless, thanks to the M Series’ comprehensive connectivity options. The amplifiers feature XLR and TRS inputs, allowing for seamless integration with a wide array of audio sources. Their ability to be controlled remotely allows for convenient adjustments during live events or installations, further enhancing their usability.

The built-in DSP (Digital Signal Processing) is another critical highlight of the M Series. This technology provides users with significant control over the audio signal, enabling adjustments such as equalization, limiting, and crossover settings to fine-tune the sound output to perfection. The advanced protection circuitry ensures that the amplifiers remain safe from overheating and signal overloads, thus extending their lifespan and reliability.

Robust construction is a signature characteristic of the M Series, designed to withstand the rigors of professional use. The amplifiers feature a rugged chassis that can endure the demands of touring or permanent installations. Additionally, the fan-cooled design aids in maintaining optimal operating temperatures, ensuring performance consistency even during extended periods of use.

In conclusion, Crown Audio's M Series amplifiers combine power, efficiency, and cutting-edge technology to create an exceptional solution for professional audio applications. Whether used in concert halls, clubs, or corporate environments, the M Series continues to set a high standard for reliability and performance in the world of audio amplification.
