Need to send audio way across your house or venue without losing quality? This gofanco extender kit is your answer. It uses a simple CAT5e/6/7 cable (up to 984 feet for 48kHz signals) to transmit either Toslink digital audio (supports 5.1 channel Dolby Digital, DTS) or analog L/R stereo. It has an embedded DAC, so the receiver outputs both Toslink and analog simultaneously. There's zero latency, ultra-low jitter, and it supports high-res audio up to 24-bit/192kHz. The cool 'Power over Cable' feature means you only need one power supply plugged into either the transmitter or receiver to power both units. It's a point-to-point kit (not for networks), housed in a sturdy metal case to minimize interference. Perfect for home theaters, whole-house audio, or commercial installations where running long audio cables is a pain. Just plug and play!
