The Sescom SES-SPKNM-XLRF is a Speakonr 4 Pole Speaker Plug to 3 Pin XLR Female Loudspeaker/Amplifier Adapter designed with high power audio systems in mind. These adaptors are perfect for frequently connected/disconnected systems.
Q: What is the purpose of the SES-SPKNF-XLRM, SES-SPKNM-XLRF & SES-SPKNM-XLRM speakON-to-XLR adapters?
A: Sescom's SES-SPKNF-XLRM, SES-SPKNM-XLRF & SES-SPKNM-XLRM are intended to interface speaker-level, high-amperage XLR connections with speakON. Only the 1+ and 1- connections on the speakON connector are active (wired). These parts are very rarely used, since speaker-level connections are rarely made via XLR connectors. These parts should only be used by experienced technicians who understand the amperages involved. Never use these products to connect an amplifier output to any line-level type input! Doing so will almost surely damage equipment. These devices are not attenuators, just passive adapters.
