Technical Specification
B.1.3.1
RX8000 Audio Alignment Levels
The audio Alignment Levels on the RX8000 are configured according to SMPTE
RP155. That is, with the audio Gain and analogue Clipping Level at their default
values, a digital audio source at -20 dBFS (SMPTE Alignment Level) decoded on
the RX8000 will produce an AES output level of 0 dB(VU) and an analogue output
level of +4 dBu.

Where it is desired that the output levels of the RX8000 satisfy EBU Alignment
Levels then the Gain and/or Clipping Level can be adjusted to achieve this.
