Measuring less than 4" x 1 ½" x 1 ½" (10.16 x 3.81 x 3.81 cm), the compact design features an XLR-F input at one end and an XLR-M output at the other with solid 16 gauge steel construction and durable powder coat finish. The steel outer shell provides excellent shielding against electromagnetic fields generated by power cables, dimmers, motors and power supplies while being significantly more rugged - a very important benefit for concert touring and AV rental houses where the fast paced environment can often be very hard on gear. Connection to and from the IceCube is done using standard 3-pin XLR cables. It is also equipped with a ground lift switch to further assist in reducing noise.
