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 15 A RMS and features a compressor and an AGC to ensure optimal audio quality.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe amplifier incorporates a fault synthesis controlling continuously the integrity of both loop and amplifier. The information is displayed on the driver’s front panel and can be deported thanks to a dry contact. Thanks to our high-efficiency Class D technology, the LD4.0 amplifier consumes less and offers a natural cooling. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe amplifier's output voltage is the highest available on the market for this type of amplifier (48 Vpk), ensuring outstanding sound quality without clipping or distortion. The variable frequency of switching class D amplifiers developed by Opus Technologies allows unequaled performances and exceptional sound signal in the most compact device on the market.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe LD4.0 can also be used in a low diaphonic phased loop system or an ultra high coverage system with a built in 90 ° or 0 ° phase shift module (2 amplifiers).
