TRANSFORMER ISOLATI ON MODELS®LINE T RANSFORMER: TX4L and RX4L modules are transformer isolated at the XLR outputs and at the Ethernet THRU connector to provide line level isolation to eliminate hum and buzz. MIC TRANSFORMER: TX4M and RX4M modules are transformer isolated at the XLR outputs and at the Ethernet THRU connector to create a mic level split for stage and studio use. 2

®5MAKING CONNECTIONSAs 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 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. Cat 5

®Cat 56Using Mic Level TX4M and RX4M isolated modulesThese modules are typically employed when splitting a mic signal between two mixers. Although the transformers may be ordered inside either the transmit TX4M or receive RX4M boxes, these are usually put For instance, you may be doing a gig where your stage mics need to be sent to a monitor mixer by the stage, as well as a distant front-of-house mixing console. The TX4M would allow you to directly connect your microphones to the FOH console so it can provide phantom power, while high-performance Eclipse transformers keep the monitor mixer isolated and prevent ground loops. You can also use the same TX4M module to isolate the microphones to feed a separate recording system. Transformers are truly amazing devices that surprisingly come in handy in all types of situations. RX4MMIXER / FOHRECORDERTX4MMIXER / MONITOR Isolated OutIsolated OutDirect Out

®7Using Line Level TX4L and RX4L isolated modulesAs described above, transformers eliminate noise. These problems are often most predominant in situations where the two connection points are distanced from each other. In these setups, the electrical circuits are often on different power legs which can sometimes cause noise to enter the PA system. Isolating the signal allows the audio to pass while blocking the stray DC voltages that can disrupt the system. Line level isolators are usually positioned at the receive end (RX4L) of the a return snake for monitors or from a crossover, isolating the stage from the front-of-house (FOH) can save hours of trouble shooting! Simply connect the output from your console to the Catapult and the isolated outputs to your amp racks or powered speakers. The Eclipse transformers inside are capable of handling up to 15dB without distortion. If you like, you can use the non-isolated outputs to feed another piece of equipment such as a recorder.

Using the Catapult as a return snakeThe Catapult is the perfect return snake for corporate events where you need to run a couple of lines back to the stage and monitors. Use the RX4L line isolation module to eliminate ground loops. Using the Catapult as a sub snake on stageCleaning up the stage while reducing the set-up times has become es – sential in production. Use the Catapult at the front of the stage or next to the amps to create zones for quick deployment.
