D.A.S. Audio Explains Line Array Line

D.A.S. Audio has expanded the Event series of line arrays and bass systems with two new powered models, the Event-212A line array and the Event-121A subwoofer. The new products are aimed at providing Event Series users with the tools needed to handle an even a wider range of applications.

The D.A.S. Event-212A is a powered, three-way line array which employs two D.A.S. 12-inch loudspeakers in a dual band configuration where each speaker operates in a specific frequency range. The D.A.S. loudspeaker units have been teamed up with a single M-75 compression driver and purpose-designed injected aluminum high frequency waveguide to provide unmatched performance, sensitivity and coverage in both the 90º and 120º formats offered.

The Event-212A line array incorporates the DAS control interface that offers a quick and hassle-free set-up of the systems in arrays and easy alignment with the Event-218A and Event-121A subwoofer systems. Presets for the number of units of the array, HF compensation for throw distances and correction for the splay angle of the array can be selected by way of DAScontrol and the LCD screen located on the back of the cabinet. The powerful digital signal processing of the Event-212A includes Finite Impulse Response (FIR) filters providing linear phase response and precise impulse response which, in terms of performance, results in added clarity, defined attack in percussion and overall, a more natural sound.

Along with the new line array, D.A.S. launches the Event-121A, a direct radiating rear-loaded powered subwoofer system which incorporates a single 21-inch neodymium loudspeaker to provide “earth-moving” low-frequency reproduction for the Event Series line arrays. The combination of direct radiation and rear-loading provides a high output, tight and accurate sub-bass response.

The Event-121A employs the new D.A.S. 21LFN loudspeaker which offers impressive features such as a 4-inch sandwich split winding voice coil, a powerful FEA optimized neodymium magnet assembly and a FEA optimized suspension system with double silicon spider. The result is a loudspeaker with exceptional sensitivity, high power handling capacity and a quality suspension design capable of withstanding the stress and mechanical fatigue of today´s high-power pro audio systems.

An aluminum demodulating ring benefits lower distortion and effective forced ventilation of the voice coil gap provides for a high thermal rating, and reduced power compression.

The Event-121A electronics package includes a 3200 watt peak Class D amplifier and 24-bit high-end DSP for top quality audio reproduction. On the rear panel, controls can be found for gain, polarity and a continually variable low-pass filter that ranges from 63 Hz to 100 Hz. A unique “cardioid preset” button simplifies the use of subs in cardioid configurations, making setup of two to three units a snap without the need for an external DSP. The Event-121A is phase response coherent with the Event-208A, Event-210A and Event-212A active tops offering precise alignment. Two balanced inputs with stereo filtered outputs, which can be switched to pass-through connections, are provided.
