Overview
The MUX-8258 is a high quality program analog multiplexer that is extremely flexible in handling channel
assignments and channel re-mapping as well as fully reconfigure, append, and overwrite capability for existing
channels.
MUX-8258-A and MUX-8258-B Overview
The MUX-8258-A and MUX-8258-B are capable of embedding up to eight AES/EBU pairs (16 audio channels)
into an HD/SD-SDI signal. Audio proc control on each input allows for audio processing with independent channel
Sample Rate Conversion (SRC), gain of +/-20dB, audio delay up to 1 second and channel phase invert and
summing capability. If the input is a synchronous 48kHz signal, the audio can be embedded into the SDI signal
unaltered. If the input is not a synchronous 48kHz signal, it may be converted using SRC before it is embedded on
the SDI output.
Note that the MUX-8258-A offers eight 75ohm unbalanced AES connections while the MUX-8258-B offers eight
110ohm balanced AES connections.
MUX-8258-C Overview
The MUX-8258-C includes one multi-rate SDI input which supports up to 16 channels of embedded audio and four
or eight channels of analog audio inputs (MUX-8258-4C and MUX-8258-8C respectively). The MUX-8258-C is
capable of embedding up to eight analog audio channels into an HD/SD-SDI signal. Audio proc controls on each
input allows for gain control of +/- 10dB, audio delay up to 1 second and channel phase invert and summing
capability.
Features
The following features make the MUX-8258 the ideal solution for multiplexing analog audio sources into an
HD/SD-SDI signal:
• Supports HD-SD SDI SMPTE 292M (1.5Gbps), SMPTE 259M (270Mbps), and SMPTE 424M (3Gbps)
