Pyramix Mixer : Mixer Delay Compensation
Delay Chart
Time Alignment of Recorded Clips
All recordings from Input Strips designated as
Input
are automatically time-aligned. E.g. recordings from
live inputs.
Recording Bus Returns
When recording the output of an input strip taking an Aux or Bus return, for example to “freeze” a reverb
track, the recorded media will be placed too early in the Timeline. In this situation it may therefore be desir-
able to designate this Aux or Bus return as a normal
Input
in order to ensure correct time-alignment of the
recorded clip.
Note:
For Power Users the
SABR
debug windows show the delay values applied to each
bus / aux node and may prove useful.
Delay Compensation Detail
All digital processing takes a finite amount of time. When
Internal Return Busses
are used to route
Aux
or
Master
output busses back into channel inputs (by selecting an
Internal Return Bus
input from the routing
pop-up for the
Aux
or
Bus
output, and selecting an
Internal Return Bus
output as the return channel
input) all other busses not so routed must be delayed if the Mixer is to be ‘time-aligned’ I.e. If a signal is fed
to two inputs, the first feeding the Main Output direct and the second routed back to an input via (say) an
Aux
bus with the return input strip routed to the Main Output, then the second will be delayed with respect
to the first. Selecting
Settings > Enable Delay Compensation
from the mixer context pop-up menu will
automatically ensure both signals remain in sync by delaying the signals directly routed to the Main Output
by an amount equivalent to the delay introduced by the extra processing in the second path.
Input Strip Mode
In order for Pyramix to correctly calculate the required delay you have to tell it which bus is the source for
the Internal Return Bus. Clicking
on
Input
at the bottom of the strip, above the XLR icon, pops-up a list of
