One of the names given to a pluggable terminal block suitable for use with audio where connection to permanent wiring makes their use more suitable than XLR or Jack connectors.

Transient

A sudden burst of energy in an audio signal which only lasts for a small period of time relative to the rest of the signal. The level of these transients can often reach 10 times (+20dB) or so above the normal operating level of the audio equipment, and may cause distortion if headroom is inadequate.

Speakon®

XLR

A type of connector used by audio professionals for connecting audio line, or microphone level signals to equipment. Usually three pole. Note that some XLRs may be carrying AES/EBU digital signals and these should not be plugged into audio channels.
