3.7 XLR Expander Card Option (M2/EOM2/XLR)
3.7.1 Overview
NOTE…
The M2/EOM2/XLR XLR Expander Card Option is supported by Build version 3.0 and later.
The XLR Expander Card Option permits Encoders to input and output a
stereo audio pair via XLR connectors. The option occupies two vertical
option slots, 1 and 4, due to the size of the XLRs. Because of this it is
available on the 2U version only.
The Audio menu associated with this option is described in Chapter 4,
Operating the Equipment Locally.
3.7.2 Audio Inputs Receiver
The input accepts both analogue and digital AES/EBU (left channel only).
When the unit is powered down the inputs default to digital. The input
impedance of the digital channel is 110 W, while the analogue input
operates at either 600 W or 20 kW.
The analogue receiver works at clip levels of 18 dB or 15 dB. Analogue
inputs are sampled at 48 kHz. The signal from the audio receiving inputs is
routed to the backplane as a single AES/EBU formatted digital signal.
3.7.3 Audio Outputs Transmitter
The XLR outputs deliver both analogue or digital AES/EBU (left channel
only). When delivering digital audio the output impedance is 110 W. The
analogue output is low impedance. The analogue transmitter works at
15 dB or 18 dB FSR.
The audio transmitter may select its source from any of the following:
· Four AES/EBU de-embedded feeds from the SDI feed
· Two of the AES/EBU feeds from the decoder
· Loop back
· Off
The analogue signal is reconstructed, based on the sampling rate of the
AES/EBU signal source.
