Whirlwind Catdusa - 4-Channel Audio Over Cat5 ExtenderCatdusa is a 4 channel analog snake box that uses shielded Cat5 cable instead of traditional multipair cable. Each channel has paralleled male and female xlrs, allowing for greater flexibility. The two Neutrik Ethercon RJ45s (IN THRU), let you daisy chain multiple boxes. If shielded Cat5 cable is used, Catdusa can pass phantom power and DMX. The Mini stage box design means Catdusa can be placed almost anywhere. Minimum 2 Catdusa boxes required.
