Embedding formats
Operator selection of enhanced SMPTE or SONY formats
Standard selection
525/625 automatic
EDH
EDH insertion on embedder and EDH checking on de-embedder
Audio channel gain
Eight channels of variable audio gain provided from 0% (mute) to 799%
Delay/Phase inversion
Dual channel digital audio delay - OFF or pre-settable in 1ms steps from 1
– 681ms. In addition each channel may be phase inverted
Silence threshold delay
Silence threshold delay for both sides is pre-settable for the amount of
time a signal is allowed to remain below –50dB wrt Full Scale before a
silence error is flagged. Values start at 1.5s, 8s and then in increments of
8s to 120s
Setups
Sixteen set-ups are available to store setup data. They may be recalled
either from the board control or through the use of external GPIs
GPIs
Four GPIs are available for external recall of setups and two are available
to provide alarm monitoring
Status monitoring
Front card edge visual monitoring with alphanumeric and LED indicators.
Remote control panel also available
Maskable GPI output of inputs/references present and silence
Weight
250g with two sub-modules fitted
AIP2: Dual analogue audio input sub-module
