LD2.0
Description :
The LD2.0 is a high-efficiency Class D amplifier designed to cover a 450 m² room in a single loop. It includes three units: two switchable inputs (combo and terminal block) that support line or microphone mode, and a priority 100 V input. The device delivers an output current of 7 A RMS and features a compressor and an AGC to ensure optimal audio quality.
