The 8-channel integrated multiplexing AES/EBU audio + XLR analog optical transmitter/receiver adopts digital coding technology.
The 8-channel integrated multiplexing AES/EBU audio + XLR analog optical transmitter/receiver adopts digital coding technology. The audio interface is balanced XLR(Canon), which can transmit 8 channels of digital or analog audio signals through a single-mode fiber to achieve long-distance bidirectional transmission. The maximum signal can be transmitted without distortion and without relay 120 km.
The audio optical terminal comprises an optical transmitter and an optical receiver, which can be configured into 4 channels of bidirectional audio and 8 channels of one-way audio.
● All digital optical fiber transmission platform, the same platform multi-service flexible configuration19-inch 1U aluminum alloy anodized housing, IP40 protection grade;
● 19 “1U aluminum alloy anodized case,IP40 protection grade;
● Using FPGA, digital codec and clock recovery technology, high integration and stability.
● The analog audio interface is XLR cannon balance interface, the audio adopts 24Bit AD/DA,128K sampling, and the transmission quality of the studio level;
● Digital audio AES/EBU interface is XLR cannon head balance interface, three standard sampling rates of 32kHz, 44.1kHz, 48kHz simultaneously support;
● Each 2 audio channels can be analog audio and digital audio options.
● Audio interface provides level 3 lightning protection and can pass ITU-T K.21(10/700μS), common mode :6KV, impedance (40Ω) test.
● Single-fiber transmission, dual fiber optional
● Multiple power modes are available: AC220V, DC-48V/DC24V, and support dual power backup: AC+AC, AC+DC, DC+DC.
