To operate a DSA loudspeaker, pre-performances checks and adjustments should be made. In typical permanently installed applications, these checks would normally be one-time, set-up adjustments that may only need to be periodically verified. All of these steps require using DSAPilot.

1.Set the Power Management function as appropriate for your application.

2.Select each cluster in the DSAPilot design and verify the LED indicator illuminates on the corresponding physical cluster.

3.Verify that the LED indicator on each enclosure is at the top or bottom as shown in DSAPilot.

4.Adjust the input gain for each cluster for the desired nominal output level for the expected input signal levels.

5.Adjust the input EQ for each cluster for the desired voicing to accom- modate room acoustics, program content, or personal taste.

6.Adjust the input Limiting for each cluster to prevent higher than desired output SPLs.

Power is applied to DSA in one of three ways:

1.Always On: Connect the loudspeaker to a continuously powered AC mains supply. The loudspeaker is always ready for use. For this mode, disable the Power Management function.

2.Off/On: Connect the loudspeaker to an AC mains supply which is switched on and off between uses. The AC mains must be switched on for each use. For this mode, disable the Power Management function.

3.Standby/On: Connect the loudspeaker to a continuously powered AC mains supply. The loudspeaker will be ready when input signal is applied. For this mode, enable the Power Management function.

When powered up, the signal processing in each loudspeaker will be set to what it was for the previous use. The signal processing settings are retained by non-volatile memory in each loudspeaker. This memory will last indefinitely when connected to the AC mains. When disconnected from AC mains, a battery supplies power to this memory. The expected battery life without being connected to the AC mains is 10 years.

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.
