The local attention of Speakon Connector in daily use
2017-12-04

Speakon connectors are a higher current carrying alternative to TS connectors (1/4-inch phone jacks), two-pole twist lock, and XLR connectors for loudspeakers. Speakon connectors lock into their sockets with a twisting motion, making them significantly less prone to disconnection than standard TRS plugs.


Speakon connectors are fully shielded from human touch, preventing electrical shock risks associated with high power audio amplifiers and unshielded connections. Speakon contacts do not short out upon connection or disconnection, which can happen to the 1/4-inch plug as it is being plugged in. This can be a benefit when working with sound equipment that is in operation.


Speakon connectors are designed to be unambiguous in their use in speaker cables. With jack and XLR connections, it is possible to use low-current shielded microphone or instrument cables in a high-current speaker application. Speakon cables are intended solely for use in high current audio applications.


Speakon connectors are made in two, four and eight-pole configurations. The two-pole line connector will mate with the four-pole panel connector, connecting to +1 and −1; but the reverse combination will not work. The eight-pole connector is physically larger to accommodate the extra poles. The four-pole connector is the most common at least from the availability of ready-made leads, as it allows for things like Bi-amping (two of the four connections for the higher-frequency signal, with the other two for the lower-frequency signal) without two separate cables. Similarly, the eight-pole connector could be used for Tri-amping (two poles each for low, mid and high frequencies with two unused), or quad-amping (two poles each for high, mid, low and sub).
