Ideal for live entertainment, theatres, lecture halls and conference facilities, this four-channel receiver combines transparent 24-bit digital audio with exceptional RF reliability. Featuring a 118 dB dynamic range and wide tuning capabilities, it provides clear, consistent sound across demanding professional applications.\u003c\/span\u003e\u003c\/p\u003e \u003cp\u003e\u003cspan\u003eDesigned to maximise efficiency, the SLXD4Q+ accommodates four wireless channels in a single rack space, reducing equipment requirements without compromising performance. Its audio summing functionality allows four channels to be routed across four, three, two or one mixer outputs, while RF cascading enables two SLXD4Q+ receivers to be linked for an eight-channel system. Digital predictive switching diversity further enhances reception stability.\u003c\/span\u003e\u003c\/p\u003e \u003cp\u003e\u003cspan\u003eThe SLXD4Q+ offers straightforward setup through automatic frequency scanning and infrared transmitter synchronisation. With four balanced XLR outputs, four 6.35 mm audio outputs, Ethernet connectivity and switchable antenna bias voltage, it provides flexible integration into professional sound systems. Its rugged galvanised steel construction ensures durability for both touring and permanent installations.\u003c\/span\u003e\u003c\/p\u003e
