The OnQ legrand AU7428 lyriQ Triple Source Input converts and sends line-level audio from up to three audio components (i.e. Stereo Receiver, CD Player, Tape Deck, etc.) to an audio distribution module via Cat 5e cable. It is an integral part of the lyriQ Audio System, which utilizes Category 5 technology to distribute high quality audio to remote locations via Cat 5e cable, creating a versatile whole-house audio system that will fill your rooms with high quality sound for years to come. This technology provides many advantages over conventional methods of audio distribution, such as simple Category 5 wiring schemes, infrared control of system components, and improved sound quality due to an amplifier being located in every room. This unit also receives IR control codes from the Volume Control IR Targets and passes them to the emitter output ports for control of the source equipment.
