Thank you for purchasing the Radial Catapult Mini™ modular snake, a Cat
5 analog audio snake system that is designed to clean up the stage, simplify
setups and take advantage of pre-existing wire infrastructure. Although
these devices are designed to be easy to use, please take a minute to read
through this short manual in order to take full advantage of their functionality.
If you have any questions not answered within, please visit the Catapult FAQ
page as this is where we post questions and answers from users along with
updates. If you still nd yourself with more questions, you can always reach
us by email at [e-mail].

OVERVIEW

The Catapult Mini RX and TX act like a typical four-channel analog audio
snake; they allow you to send mic or line-level signals from one location to
another without signal loss, noise, or interference, and without any digital
audio conversion needed. The difference is that instead of using bulky and
expensive multi-channel audio cable, the Catapult system makes use of Cat 5
Ethernet cable, which is widely available, lightweight, and economical. Simply
connect a shielded Cat 5 cable between any two Catapult modules and they
will use the cable’s analog conductors to deliver four balanced audio lines
to any destination. As many buildings are already pre-wired for Cat 5, you
can take advantage of this to transmit audio between distant rooms without
the need to install or supply new cable. And since the Catapult system is
modular, you can mix and match different transmit and receive boxes to best
suit your application.

USING THE MINI TX WITH THE MINI RX

To use the Catapult Minis in their simplest form, connect the Mini TX and the Mini
RX together using a Cat 5 cable. As the twisted pairs within an Ethernet cable
are tightly wound together in a compact jacket, it’s a good idea to send signals
of a similar level together over the same wire as this will reduce crosstalk from
higher signal levels (such as +4dB line levels) bleeding into lower volume signals
(such as -30dB mic levels).

USING THE MINI RX WITH THE CATAPULT TX4/TX4M/TX4L

You can use the Catapult TX4 with the Mini RX to send audio signals from a
live stage to the FOH console. The Catapult TX4 provides a robust stage box to
plug your microphones into, while the Mini RX is small enough to t in the case
of a mixing board, with the XLR outputs plugged directly into the mixer. To split
the mic signals to a monitor mixer located beside the stage, the TX4M can be
employed, as it features isolation transformers optimized for mic-level that will
eliminate hum and buzz from ground loops between the two mixers. For splitting
line-level signals at the source, the TX4L is also available.

USING THE MINI TX WITH THE CATAPULT RX4/RX4M/RX4L

The Mini TX can be paired with the Catapult RX4 to feed the outputs of a
console to a distant rack of power amps. To block stray DC voltages and
avoid noise through the system, the RX4L has line-level isolation transformers
to eliminate hum and buzz, as well as four direct XLR outputs to also feed
another device such as a recording interface. If microphone splitting is
required at the destination, the RX4M has transformers optimized for this task.

TAKE ADVANTAGE OF PRE-EXISTING CAT 5 WIRING

Use the Ethernet cables already wired throughout a building to send audio
from one room to the other without additional installation or messy cables.
Note that the signals between two Catapult modules cannot pass through a
network switch, as it will block the analog audio signal.

MAKING CONNECTIONS

As with all audio systems, it is good to turn volume levels down or audio
systems off before making connections. This will avoid connection or power-

Isolated

up transients from damaging more sensitive components such as tweeters.

You can use any standard Cat 5 or Cat 6 Ethernet cable to connect Catapult
modules to each other. In order to pass 48V phantom power to feed your
condenser mics or active direct boxes, the cable and terminating connections
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.
