This nominal 5" by 7" input cup comes pre-drilled with two 29/32" holes designed to fit standard Neutrik SpeakOn jacks, plus two 7/16" holes designed to fit 1/4" jacks. On the rear of the input cup are six 1-3/4" standoffs that allow the attachment of PC boards or any type of custom crossover board, while still allowing room for large input jacks. The extended standoff space and large overall size also make this cup excellent for use with L-pads. Heavy-duty injection-molded construction with a thickness of over 4mm offers superior stiffness and rigidity compared to other input cups. Overall dimensions: 5-3/16" wide, 7-3/16" long, 2-3/4" depth. Cutout size: 4" by 6".
