Always use good quality cables to achieve the maximum cable lengths shown below:
Signal (connector) Cable length Connection
Analog (XLR) up to 100 m
(300’)
directly to the ANALOG INPUT socket (XLR/Jack)
(see below)
Analog (Jack) up to 100 m
(300’)
directly to the ANALOG INPUT socket (XLR/Jack)
(see below)
Analog (RCA) up to 10 m
(30')
via an adapter (RCA-XLR or Jack-XLR) to the
ANALOG INPUT socket (XLR/Jack) (see below)
If possible, use a balanced connection (XLR, stereo Jack) in order to avoid interference in
the cable.

Use an XLR or Jack adapter (not supplied) to connect unbalanced cables (e.g. RCA cables).
X
Use this adapter directly at the source and connect the adapter via a properly wired balanced
XLR cable to the loudspeaker. The connection of pin 3 to ground should be as close as pos-
sible to the source to maximize hum rejection on the cable.

Use the following wiring if you want to make your own RCA to XLR cable:
