MAKING CONNECTIONS
As with all audio systems, it is good to turn your audio system o󰀨 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 conguration, but it will still be benecial
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.
