Technical Specifications
| Directional Technology | Employs an intelligent speaker array system based on beamforming algorithms, combined with phased array technology. It utilizes digital control of 8 speaker units to achieve dynamic focusing and precise coverage of the sound field. |
| Desktop Mixing Control | The device supports connection to a simple desktop mixing console, enabling the call-up of presets, volume adjustment, and on/off control. |
| Embedded Speaker Array Design | Each speaker unit in the array supports independent control. Via a dedicated control system, fine-grained parameter adjustments can be made for individual units, including gain adjustment for output volume (continuously adjustable within ±20dB), delay adjustment based on acoustic distance, and independent on/off control. |
| Front-Back Sound Pressure Level (SPL) Difference (Directivity) | Full Frequency Range: Average SPL Difference ≥ 22dB 125Hz – 250Hz Band: SPL Difference ≥ 18dB◦ 250Hz – 500Hz Band: SPL Difference ≥ 20dB◦ 500Hz – 1kHz Band: SPL Difference ≥ 22dB◦ 1kHz – 18kHz Band: SPL Difference ≥ 25dB |
| Horizontal Directivity Adjustment | Adjustable Angle Range: ≥ ±45° (Total coverage angle ≥ 90°), enabling wide-angle coverage and precise steering in the horizontal plane. |
| Adjustment Precision: Horizontal steering precision reaches ±10°, supporting positioning at any angle within a 0-180° range to ensure flexible sound field alignment according to the environment. | |
| Compressor/Limiter (ALC) | Supports Auto Level Control with configurable parameters such as threshold, compression ratio, and knee, effectively controlling signal levels and preventing distortion. |
| Automatic Gain Control (AGC) | Automatically adjusts microphone gain based on speaking distance to maintain stable output volume. |
