Commercial Audio-Reihe-Verstärker verlangen Klasse die 2 Produktionsverdrahtung.

MAGNETIC FIELD

CAUTION! Do not locate sensitive high-gain equipment such as preamplifiers or tape decks directly above or below the unit. Because this amplifier has a high power density, it has a strong magnetic field which can induce hum into unshielded devices that are located nearby. The field is strongest just above and below the unit.

If an equipment rack is used, we recommend locating the amplifi er(s) in the bottom of the rack and the preamplifi er or other sensitive equip- ment at the top.

FCC COMPLIANCE NOTICE

This device complies with part 15 of the FCC rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.

CAUTION: Changes or modifi cations not expressly approved by the party responsible for complicance could void the user’s authority to operate the equipment.

NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equip- ment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio com- munications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television recep- tion, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

Reorient or relocate the receiving antenna.

Increase the separation between the equipment and receiver.

Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.

Consult the dealer or an experienced radio/TV technician for help.

160MA specifications

Crown Audio, a leading manufacturer of professional audio equipment, has made a name for itself with its innovative amplifier designs. Among their extensive lineup, the Crown 160MA and 135MA models stand out as highly regarded solutions for various applications, particularly in commercial audio systems, installations, and even mobile setups.

The Crown 160MA is a 160-watt, 2-channel amplifier that delivers robust performance while ensuring outstanding sound quality. Designed with versatility in mind, it is well-suited for powering speakers in both small venues and larger installations where high-quality audio is required. The amplifier features a built-in mixer with three inputs, allowing users to easily connect multiple audio sources. This feature is particularly beneficial in settings such as community centers, conference rooms, and educational institutions.

On the other hand, the Crown 135MA is a slightly smaller yet equally capable 135-watt, 2-channel amplifier, designed for applications where space may be limited. It retains many of the key features found in the 160MA, offering reliable performance while providing the necessary power for smaller speaker systems. The integrated mixer also accommodates various audio inputs, simplifying connections in various environments.

Both models incorporate advanced technologies that enhance performance and reliability. They utilize Class D amplification, which not only reduces energy consumption but also minimizes heat generation, allowing for a more compact design without sacrificing output power. This makes them ideal for permanent installations where space is a constraint. Additionally, the amplifiers come equipped with comprehensive protection circuitry, safeguarding against potential overloads and thermal issues.

The Crown 160MA and 135MA are also designed with user-friendly controls and indicators, making them accessible for both seasoned audio professionals and newcomers. Their rugged built quality ensures durability in diverse environments, whether being used in commercial spaces, houses of worship, or temporary events.

In summary, the Crown Audio 160MA and 135MA offer a compelling combination of power, sound quality, and versatility. Their innovative features, such as built-in mixing capabilities, efficient Class D technology, and robust protective measures, make them excellent choices for anyone seeking reliable amplification solutions.
