(1) This device may not cause harmful interference, and
(2) This device must accept any interference received
including interference that may cause undesired operation.
INPUT
Single-ended (unbalanced) inputs accept levels as
low as -30dBu. Input impedance is 50 kΩ in stereo, 25
kΩ in mono. Use the right for mono input.
FOOTSWITCH
Tip/Ring/Sleeve phone input, for momentary con-
tact footswitches, allows footswitch control of Reg-
ister Step and Bypass functions.
