As with all audio systems, it is good to turn your audio system off or
turn system levels down to zero before making connections. This will
avoid connection or power-up transients from damaging more sensitive
components such as tweeters.
using standard TX4 and rX4 (non-isolated) modules
To use the Catapult in the simplest form, connect the TX4 and the RX4
together using Cat 5 or Cat 6 cable. In order to pass 48V phantom power
to feed your condenser mics or active direct boxes, the cable must
have a shield. If you are transmitting line level signals, the shield is not
required due to the twisted pair configuration, but it will still be beneficial
as shielded cables are less susceptible to noise. As the twisted pairs are
tightly wound together in a compact jacket, it's a good idea to send similar
level signals together over the same wire as this will reduce crosstalk
from higher signal levels (such as +4dB line levels) polluting lower output
signals (such as -30dB mic levels). TX and RX modules are equipped
with two sets of XLRs to enable greater connectivity. This is basically a
simple Y-jack that can be handy in certain situations.
