Chapter 6 Operation

The general operation of a DSA loudspeaker is similar to the operation of most loudspeakers. Initial system set-up and overall tuning adjustments detailed in this Chapter must be made using DSAPilot. For details about using DSAPilot functions refer to the DSAPilot Help File. Performance operation is largely concerned with adjusting the operating levels, avoiding excessive input signals and, if needed, making in-performance “voicing” adjustments using external equalization

These operation instructions assume that the loudspeaker has AC Mains, audio signal, and computer control lines properly connected, and that they are passing signals correctly.

There are several, unique functions that affect and enhance operation. These include Power Management, LED Indicator, and signal Monitoring.

The Power Management feature is a power saving function that improves energy efficiency. This feature automatically puts the DSA amplifiers into stand-by mode similar to a computer monitor. The initiation of this mode occurs after the input signal is absent for a period of time.

Enable or disable this function using DSAPilot. If enabled, the period of time the input signal must be absent before entering stand-by is adjustable. In addition, DSAPilot allows forcing the standby condition should the need arise to de-activate the amplifiers without disconnecting the AC mains.

The LED Indicator located on the front of a DSA loudspeaker at the “Signal End” can be set to indicate the status of several operating conditions. Enable or disable each indication using DSAPilot. The actual conditions monitored by the LED are not affected by enabling or disabling the LED indication.

1.Initialization: The LED on the “Signal End” will flash rapidly for about 3 seconds when first powered on. This is normal and indicates the electronics are being initialized. The LED should then go off. This indication is permanently enabled.

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.
