The PRO X system can be divided into conceptual ‘zones’, as follows:
• System Input Zone: DL251 Audio System I/O, DL351 Modular I/O, DL431
Mic Splitter or DL451 Modular I/O/AES3 inputs, which are normally routed
to input channels. These inputs are primary system inputs and the control
centre output latency is measured relative to these inputs.
• Mix Zone: Aux outputs, return inputs and master/matrix direct inputs,
which can be freely patched to and from internal or external eects, while
maintaining output signal alignment.
• Output Zone: System outputs, that is, master and matrix outputs when
Monitor Mode (Align with Masters) option is switched o, or aux, master
and matrix outputs when it is switched on.
Aux direct inputs are xed to the System Input Zone, so that system inputs that
are routed to an aux direct input will automatically line up with inputs routed to
auxes via input channels.
Return inputs and master and matrix direct inputs can be congured to operate
in either the System Input Zone (for example, as additional control centre inputs)
or the Mix Zone (for example, as eect returns) and are congurable on a per
channel basis.
Examples of patches using the Mix Zone that are all fully compensated when the
Send-FX-Return delay compensation is switched on are:
• Aux -> Internal/External Eect -> Return
• Aux -> Internal/External Eect -> Master Direct Input
• Aux -> Internal/External Eect -> Matrix Direct Input
For all system inputs — including insert return points — the actual location
of the input XLR is automatically compensated for, so an insert using I/O at the
stage location will produce the same latency as an insert at FOH.
Input channel direct outputs are simply a copy of the input channel output or mic
input signal, depending on the direct output mode for a particular channel. It is
not possible to delay these signals to line up with the main system outputs or aux
outputs, so patching from a direct output to an eect and back in to a return/
master direct input etc. cannot be fully compensated for.
The input to direct output latency depends on the direct output mode and input
channel insert delay compensation status according to the following table.
