Why are software returns disabled?
When the interface operates at higher sample rates (i.e., 88.2/96 kHz or 176.4/192 kHz), certain hardware input and output ports become disabled due to S/MUX II and S/MUX IV operation. When this happens, the Control Panel automatically scales the number of software return channels to match the number of hardware outputs. See the section entitled “Architecture of ProFire 2626” to learn about which specific hardware I/O and software return channels become disabled at various sample rates.
NOTE: If you wish to use the DSP Mixer of ProFire 2626 for input monitoring, be sure to mute your DAW application’s recording channels (or, if possible, turn off the application’s monitor mixing functionality altogether) to prevent two separate cue mixes from being created (this can cause undesirable effects such as phasing and
The DSP Mixer can be bypassed by either muting all of its input channels or by making sure that the Mixer’s outputs are not routed to any hardware outputs in the Router (see the following section to learn more about the Router).
Keep in mind that that the DSP Mixer channels have up to seven auxiliary sends* that can be shown or hidden using the
“+” and
Aux sends can be routed to any of the hardware outputs on the interface via the Router tab and can be used to send signals to external effects processors just like an Aux Send on a traditional mixing console. Another common use of this functionality is to create custom cue mixes for separate performers (this topic is covered in “Example Scenario #1” section of this guide). The aux sends are in stereo and will always maintain the pan settings made in the DSP Mixer channels.
* When operating at 176.4 or 192 kHz sample rates, the number of available auxiliary sends is reduced to one.
