Audio-Technica ATUC-F11 Foam Insert

Each ATUC-F foam insert is cut with cavities that hold a specific mix of ATUC-50 or ATUC-IR discussion system components in place inside an SKB 3R2817-10 case or equivalent (case not included), so a rack of units, microphones, and batteries travels without rattling or crushing connectors. F11 and F12 are built for wired systems: F11 holds twelve ATUC-50DU discussion units and twelve microphones, while F12 holds one ATUC-50CU control unit plus four discussion units and four microphones.

F13 and F14 are built for the infrared wireless ATUC-IR line: F13 holds ten ATUC-IRDU units, ten microphones, twenty LI-240 lithium-ion batteries, and one ATCS-B60 charger, while F14 adds an ATUC-IRCU control unit to a smaller set of discussion units and microphones. All four accept the same ATUC-M43H, ATUC-M58H, or ATUC-M32L microphones in their cutouts.
