M Series Power Amplifiers

2 Setup

2.7 Connect to AC Mains

Connect your amplifier to the AC mains power source (power outlet) with the supplied AC power cordset. First, connect the IEC end of the cordset to the IEC connector on the amplifier; then, plug the other end of the cordset to the AC mains.

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

Amplifiers don’t create energy. The AC mains volt- age 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 a 10% variation above or a 15% variation below the amplifier’s specified line voltage and within the specfied 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.

2.8 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 Power indica- tor 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 installation changes, don’t forget to disconnect the power cord.

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

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.
