DAS Event-210A Line array

The Event 210A makes use of the M-75 compression driver with 75 mm aluminum EFW voice coil and titanium diaphragm for HF reproduction. The proprietary injected aluminum HF waveguide has been designed specifically for the Event Line Arrays providing precise 90º horizontal coverage. The Event 210A low/low-mid frequencies are reproduced by two 10" cone speakers. This section uses a "twin-band" configuration where each speaker operates in a specific frequency range. At low frequencies, the speakers work in tandem for maximum power, each driven by a dedicated amplifier channel providing 360 Wpeak output power. Above the low frequency range, the advanced digital signal processing feeds the mid signal to only one of the two low fr equency drivers, while the other is rolled off. This technique eliminates off-axis interference between the drivers enabling the Event Line Arrays to maintain optimal polar and frequency response characteristics throughout the low and low-mid operating ranges. Each individual enclosure for the low frequency drivers has been tuned to provide optimum response for the specific operating range of each driver. In the same fashion, the digital signal processing, limiting and protections are specific to each way, reducing intermodulation distortion. The Easy-DSPTM Interface provides fast and easy line array configuration. The frequency response of each unit can be modified depending on the number of units in the array. A “downfill” correction is also available.
