AES/EBU Audio: Provides a synchronized AES/EBU audio path for in-line
replacement of programming audio during EAS operations. If an input is provided
(from a station source), the output sample rate will be equal to the input sample rate. If
no input is provided, the output sample rate will be 48 KHz.
AES/EBU input: 110

BNC serial digital interface output compliant with SMPTE 259M, 292M, and
274M standards. Supports embedded audio, audio replacement, and video overlay. SDI
OUT is synchronized with the SDI IN signal. If the SDI IN signal is lost, SDI OUT continues to
provide video at the last sampled input rate. On power failure, the SDI IN signal is routed to
the SDI OUT connection using a fail-safe relay.

Audio outputs: 600
Ω
balanced audio stereo pair provides the program audio input signal
during normal operation. During EAS or auxiliary audio operations the Visionary internal
audio is supplied to these outputs.
Audio inputs (program): 600
Ω
balanced audio stereo pair routed to the audio outputs
through relays during normal operation. During audio replacement operations the program
audio inputs are disconnected from the audio outputs.
Audio inputs (EAS): 600
Ω
balanced audio input is normally connected to an audio output
from the EASyCAST EAS encoder/decoder. It provides a means to deliver EAS audio to the
internal circuitry of the Visionary for audio replacement operations.
