The following table shows the action taken for various Aux connection patterns in the
various Aux port modes:
AUX X AUX Y
2+Mute ACTION
(State or Event)
3 Snaps ACTION
(State or Event)
4 Snaps ACTION
(State)
3+Mute ACTION
(State)
Open Open No Change No Change Recall Snapshot 1 Recall Snapshot 1
Gnd Open Recall Snapshot 1 Recall Snapshot 1 Recall Snapshot 2 Recall Snapshot 2
Open Gnd Recall Snapshot 2 Recall Snapshot 2 Recall Snapshot 3 Recall Snapshot 3
Gnd Gnd Mute Recall Snapshot 3 Recall Snapshot 4 Mute
Some of the above modes allow the AUX Port to be used:
•
Either in Event mode (whereby a momentary push-button or momentary relay contact
closure on one of the AUX lines will cause a Snapshot to be recalled).
•
Or in State mode (where a rotary switch etc. connected to both of the AUX lines selects
which Snapshot to use).
Some of the other modes only allow State mode, requiring the connection pattern to persist
in order for the Snapshot to be held as the current one.
NOTE: That if the contact closure port is being driven, or if the Aux Style is set to
one of the
State
modes, this will override the snapshot recall setting in the menu (or
in System Engineer). Also under these conditions, the snapshot menu items are not
accessible, and the Home screen will show the Snapshot number as a reminder.
Also see Snapshots on this page.
5.3 Latency Delay
All Digital Signal Processing, and conversion between different formats of signal –
analogue/digital/network etc, necessarily introduce some delay (latency) to the signal path. Of
course, we strive to minimise these latencies. Small as they are, it is sometimes useful to know
their precise values. The following describes the principal latencies introduced by various parts
of the processing:
Analogue Input
OR Digital input at 96KHz sample rate
OR Digital input at 48KHz sample rate 0.385 ms
0.5 ms
0.66 ms
Analogue Output
OR AES3 Output
OR Dante Output 0.402 ms
01 ms
0.5 ms (TBC)
Input HiShelf FIR 0.4 ms (0ms if set to Off
LIR Linear Phase crossover 1.19ms/Fhp (kHz) limited to 30ms max
1
VxLim Limiter (VX mode off) 0.12ms/Fhp (khz) limited to 1.53ms max.
1
OR VxLim Limiter 0.358 ms/Fhp (kHz) limited to 9ms max
2
Important tip:
The processing latency is constant at 1.53ms unless LIR crossover
filters or FIR HiShelf EQs are used, so normally you would just need to add the Input and
Output delays to this constant value.
