SLIM804

SLIM804 and SLIM804+(stackable) variable directional sound columns integrate domestic innovative and independently developed DSP core algorithm technology and have multiple innovative designs. According to system configuration requirements, two specifications of sound columns with and without stacking can be selected. The stacking function supports up to 32 channels to be stacked simultaneously; A single sound column supports two beams, which can be switched between single and double beams. That is, two independent beams can accurately cover two different audience areas, reducing sound reflection to the minimum; Create a cost-effective system solution that combines high-definition sound quality, consistent uniform coverage, and control capabilities.

Composed of a brand new high-strength aluminum metal casing, 8 European imported 4-inch speaker units, high-performance DSP modules, and D-class amplifier modules; By carefully selecting horn units with high consistency, each unit is equipped with an independent power amplifier channel driver, and DSP operation is used to freely adjust the vertical coverage direction from -45 º to 45 º, achieving constant horizontal beam characteristics; Equipped with dedicated installation racks, making installation easier and more convenient; Suitable for all application scenarios that require compact size and can provide high definition and consistent uniform sound pressure levels, suitable for use in places such as conferences, lecture halls, command centers, churches, museums, cultural centers, and science museums.

DSP software functions

1. The vertical pointing angle of the beam can be adjusted within a range of -45 degrees to+45 degrees (with a control accuracy of 0.1 degrees).

2. Equipment monitoring: supports network monitoring and control, with an intuitive operating interface design, making it convenient for operators to quickly deploy and monitor the silent status, online status, input channel signal size, etc. of the equipment.

3. Stacking use: The stacked version of the variable directional sound column supports stacking use, and the stacked sound column combination is equivalent to a large sound column. By stacking, the energy of sound can be enhanced and projected over longer distances. Supports simultaneous stacking of 32 channels, and can individually change the up and down reversal state of the sound column.

4. Independent control of two beam segments: capable of generating two beam segments, capable of independently controlling the switching, sidelobe optimization, target angle control, unfolding width control, center height control, beam delay control, beam attenuation control, beam graph equalization filter adjustment, high pass and low-pass filter adjustment, and other operations.

5. Audio processing: The sound column is equipped with various audio signal processing modules, including input channel mute, phase, input gain, delay, system equalization, factory equalization, beam equalization, high pass and low-pass filters, and dynamic processing.

6. Simulation calculation: The software has a built-in beam calculation rendering, through which the direction of the beam can be visually seen.

7. Save read program: Local can store 10 sets of system modes, and the boot state defaults to the first set of modes.
