ProFire 2626 User Guide 17 It is important to note that any changes made to the DSP Mixer will only affect what is audible from the mixer’s outputs—the DSP Mixer does not affect the signals that are sent to the audio application for recording For example, if you are recording a vocalist and he/she tells you to turn up the vocal track so they can hear themselves better, you can increase the vocalist’s microphone channel in the DSP Mixer This will make the vocal part louder in the vocalist

ProFire 2626 User Guide 18 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 softwa
