For the default state and the overall signal flow, refer to
“Signal flow (block diagram)”
(p. 14).
If you’re using software that has a recording monitor or input
monitor function, and select “InP” as the source being output
from the SP-555 to USB, it is possible that the audio signal will
create a feedback loop. Either turn off the recording monitor
or input monitor function in your software, or select “OFF” or
“out” for the source being output from the SP-555 to USB
audio.
