Connect a redundant microphone to a single transmitter using this BBX-SK Back-Up Box from Point Source Audio. The box itself features two female 3-pin LEMO-type connectors which accept two CONFIDENCE dual-element lavalier microphones while a male 3-pin LEMO-type connector inserts into your compatible LEMO-type transmitter. This is especially ideal for live event productions where your talent requires a contingency plan if one microphone fails.
