Thor Fiber F-1-8XLR-HIFI-TXRX 1- 8 Professional High Quality 3-PIN XLR Audio Over Fiber Extender

The Thor Fiber F-1-8XLR-HIFI-TXRX is a HIFI professional audio optical transceiver with 3-PIN XLR interface, performs high-quality 1~8-ch HIFI audio transmission over an optical line. Fiber Optic Transmitter High Quality audio signals are converted to digital signals and then converted to optical signals for transmission. Fiver Optic Receiver does the photoelectric conversion from modulated light signal to the analog XLR signal output. Used for professional and extremely high quality audio transmission over the fiber.
