The DL-A 2.4 DSC AlArray is a pair of high-end display speakers with an adjustable vertical dispersion direction for installation on large-format LCD split walls and LED video walls. Depending on the installation height of the speakers, the sound dispersion can be adjusted to the required listening area. Interference caused by sound reflections in indoor spaces is largely avoided. Using our browser-based LB AUDIO CONTROL Software, the vertical dispersion direction can be selected and saved within a range of -30° to +30°. The 16-channel active speakers have a total amplifier power of 2 × 500 watts and are designed for natural reproduction of music and speech at high volume in large indoor spaces. The electronically controlled array with 4 × 1“ high frequency drivers and 4 × 2,5“ mid-range chassis ensures a constant dispersion direction of 140° × 40° (H × V) independent from the beam direction. The integrated subwoofers give DL-A 2.4 DSC AlArrays an extended frequency range with powerful low-frequency sound. For the specific requirements of bass response or high volume we recommend our subwoofers, e. g. SUB 40, SUB 80, B 12 B or B 212 B. In addition to symmetrical analog inputs, an optical SPDIF input (Toslink) is available. The DL-A 2.4 DSC AlArray DANTE model is also equipped with a DANTE interface.

Use our DL-VESA brackets for direct display mounting. Alternatively you can use numerous attachment points are provided at the rear to facilitate mounting on a wall or on LED video walls.
