you can input stereo signals. If only the L jack of
AUX RETURN 1/2 is connected, this can be used
as a monaural AUX return. The input signal from
AUX RETURN jack 1 can also be sent to GROUP
bus 1/2 and AUX bus 1/2, and the input signal
from AUX RETURN jack 2 can be sent to
GROUP bus 3/4 and AUX bus 3/4.
