SP-14 Audio
Audio input channels are the 4x AES coaxial connectors and audio embedded in HDMI and SDI video
streams for SP-14.
The audio is passed through the system and re-embedded into the HDMI and SDI output signals with an
appropriate delay to synchronize with the video stream.
Also, audio output is present on the respective 4x AES coaxial connectors. Any PCM audio of 32kHz,
44.1kHz, and 96kHz is resampled to 48kHz.
Higher sample rate PCM audio such as 192kHz is muted.
Any compressed audio is passed through if the original audio is identified as 48kHz sampled audio or
muted.
Incoming Dolby E audio is muted.

Audio Channel Configuration
SP-14 has 4x two channel AES audio outputs and embedded audio on the HDMI and SDI video output
ports. These audio outputs carry the embedded audio of the select video input stream (HDMI or SDI) or
audio input on the 4x two channel AES audio inputs. Also, an internally generated test tone can be sent
to the audio output channels. The audio routing can be controlled with the following menu items:
Audio Input Select
This setting determines whether embedded audio of the selected video input (HDMI or SDI) or AES
audio or a test tone is sent to the audio output channels. Also, the audio can be muted globally for all
channels in this menu.
Input Pair 1 Mute, Input Pair 2 Mute, Input Pair 3 Mute, Input Pair 4 Mute
By default embedded audio and AES audio is passed through the system if the hardware does not need
to decode and encode compressed audio for resampling or is capable to resample PCM audio (see
table above).
The system can be forced from this Auto mode to Always or Never for each audio input channel
individually. Always mutes the channel and Never let all audio data pass through the system regardless
of hardware limitations.
Output Pair 1 from, Output Pair 2 from, Output Pair 3 from, Output Pair 4 from
By default the audio output channels get the audio input channels in sequential order. Each audio output
channel can be assigned a different audio input channel or they may all get the same signal.
