ENGLISH OPERATION MANUAL
JB SYSTEMS 4/20 KM4.1 / DE600 MIXER+ECHO
19. Input Aux1: Used to connect any line level sound source. Use the Aux1 control (10) to adjust the
input level.
20. Input Aux2: Used to connect any line level sound source. Use the Aux2 control (9) to adjust the
input level.
21. Master output: Used to connect an amplifier. Both aux and microphone inputs are mixed at the
master output. However only the output level of the 2 mixed aux inputs can be set by the master
volume (8).
22. Echo output/footswitch: Only the echo signal is present at this output.
• When the DE600/KM4.1 is used with the effect section of a separate audio mixer, connect
the effect return of the mixer to this output.
• When the DE600/KM4.1 is used to mix the microphones and aux inputs via the master
output (21), you can connect a footswitch to this connector. The echo on the microphones
will be bypassed when you connect the signal from this connector to ground (for example
with a footswitch).
23. Mains input: connect the supplied cable to a 230V/50Hz mains outlet. Before use, inspect the
cable to be sure it’s not damaged! The main input is equipped with a fuse to protect the unit.
Replace it only with the same type and value: 20mm glass fuse 250V 500mA slow blow.
