This allows stage techs to take advantage of the relatively low cost of this abundantly available cable for return snakes or for transporting balanced audio across a large stage. For the system contractor, the Catapult lets you take advantage of pre-wired networks to connect audio from one room to another.\u003c\/p\u003e\u003cp\u003eSix configurations are offered with a choice of three input modules and three output modules. Each input module features four XLR inputs, four XLR thru-puts along with two Neutrik Etherconâ„¢ outputs to connect the Cat 5 cable to the desired output module. These are equipped with RJ45 type Ethercon input and thru-put plus two sets of XLR outputs. These may be ordered without transformers for sub-snakes or to transmit AES audio signals; with mic isolation transformers for signal splitting between FOH, monitors or the recording system, or with line level isolation transformers to eliminate system noise. A ground lift switch is provided at each end for the Ethernet cable connection to help eliminate hum and buzz caused by ground loops.\u003c\/p\u003e\u003cp\u003eAs with all Radial products, the Catapult is constructed with solid 14-gauge steel to handle the rigors of live touring and is finished in a powder-coat finish to keep your Catapult looking good for years! Inside, a two-sided PCB is used to mount the connectors and transformers doubling up the solder joints for maximum durability.\u003c\/p\u003e\u003cp style=\"margin: 0pt 0pt 0pt 0pt;\"\u003e\u003cstrong\u003eMAKING CONNECTIONS\u003c\/strong\u003e\u003c\/p\u003e\u003cp style=\"margin: 0pt 0pt 0pt 0pt;\"\u003e\u003cstrong\u003e\u003cbr\u003e\u003c\/strong\u003e\u003c\/p\u003e\u003cp style=\"margin: 0pt 0pt 0pt 0pt;\"\u003eAs 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.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e\u003cbr\u003e\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eUSING STANDARD TX4 AND RX4 (NON-ISOLATED) MODULES\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eTo 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.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCATAPULT DEVELOPMENT\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eTwisted pair cable was invented by Alexander Graham Bell in 1881. Twisting the wires in a pre-determined ratio creates a magnetic field that rejects noise. Early telephones could transmit a signal several kilometers before it had to be boosted. By 1900, the entire American telephone line network was either unshielded twisted pair or open wire with transposition to guard against interference. Today, most of the millions of kilometres of twisted pairs in the world are outdoor landlines, owned by telephone companies, used for voice service, and only handled or even seen by telephone workers.\u003c\/p\u003e\u003cp\u003eThe same unshielded twisted pair configuration is employed in Cat 5 and Cat 6 Ethernet cable. This makes it effective for transmitting audio signals.
