using line level TX4l and rX4l isolated modules
As 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
system as this generally affords greater flexibility. If using the Catapult as
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.
