A CAT-5 or better cable with RJ-45-compatible connectors is required for each loudspeaker.

NOTE: Ethernet cable length is limited by specification to 328 ft / 100 m. Longer runs are possible using network hubs or switches as repeaters or by conversion to fiber optic cable.

Audio and RS-232 (for the DSAPilot control signals) must be converted to the CobraNet™ protocol and connected to the network via an RJ-45 Ethernet port. Products that do this are available from several manufacturers. Your choice will depend, in part, on how many and what form of audio signals (digital or analog) you need to distribute.

Manufacturers of converters include:

Peavey, QSC, Rane, Symetrix, Whirlwind, and Yamaha.

An optional EAW CM-1 CobraNet™ Interface Card must be installed in the slot provided in loudspeaker. To do this, see installation instruc- tions that accompany the CM-1.

Connect the PRIMARY RJ-45 Ethernet connector to the Ethernet cable.

The SECONDARY RJ-45 Ethernet connector on the CM-1 is for connec- ting to a second, redundant Ethernet network. This would be designed as a back-up network that automatically takes over in the event of failure in the primary network.

The digital audio received by the CM-1 connects directly to the loud- speaker’s digital signal processing. It is converted back to analog at the inputs to the internal power amplifiers.

5.2.7MULTIPLE LOUDSPEAKERS:

To connect multiple loudspeakers to the network, the Ethernet output on the audio/computer interface must connect to a network switch or hub. A network switch is normally recommended. The switch must have an Ethernet port for each loudspeaker.

A CAT-5 cable is required from the Ethernet port on the CM-1 Interface Card in each loudspeaker to its port on the network switch. For net- works requiring cable runs longer than 328 ft / 100 m, a repeater network or fiber optic cabling is recommended. Do NOT mix hubs and switches on a repeater network. Network switches and hubs are avail- able through most computer retailers.

DSA250 & DSA230 specifications

The EAW DSA250 and DSA230 are state-of-the-art powered loudspeakers designed for professional audio applications, offering high performance in a variety of environments. Both models deliver exceptional sound quality, ensuring clear audio reproduction for live events, installations, and portable use.

The EAW DSA250 features a robust bi-amplified design with a powerful 2500 watts of peak power output. This loudspeaker is equipped with a custom-designed 15-inch woofer, delivering deep and impactful low frequencies. Additionally, it boasts a 1.4-inch titanium compression driver that provides smooth mids and crisp highs, ensuring a well-balanced sound profile across the frequency spectrum.

On the other hand, the EAW DSA230 is engineered for similar high-performance needs but comes with a slightly more compact design. The DSA230 incorporates a 12-inch woofer, which still produces rich low-end sound, making it ideal for smaller venues or for use as a stage monitor. It features a 1-inch compression driver, which provides excellent vocal clarity and intelligibility.

Both models are equipped with advanced digital signal processing (DSP), allowing for optimized performance through precise loudspeaker modeling. The DSP offers various preset configurations tailored to different acoustic environments, allowing users to select the ideal settings for their specific applications. Additionally, the built-in EQ settings facilitate precise sound tuning, enabling users to adapt to various challenges presented by live sound environments.

One standout feature of the DSA series is the integration of the EAW FOCUS technology, which ensures consistent coverage and dynamic response across wide areas. This innovative technology also helps to minimize feedback and interference, making it a reliable choice for both performers and audio engineers.

The construction of both models is rugged, designed to withstand the rigors of touring while maintaining a professional appearance. They come with a sleek and practical enclosure design, featuring convenient mounting options for versatile deployment.

In summary, the EAW DSA250 and DSA230 loudspeakers are exemplary examples of advanced audio engineering, combining powerful amplification, precise DSP management, and robust build quality. With their exceptional sound reproduction, these models are ideal for professionals seeking reliable and high-performance audio solutions in diverse applications.
