Squareplug SP550-SBK, 1/4″ TRS/Stereo Pancake Plug, Black

SP550-SBK is a low-profile right angle ¼” TRS/Stereo plug with black metal shell. Suitable for balanced cable up to 5.6mm.

SP400 is a modern and functionally superior iteration of the original ‘pancake’ design introduced by Switchcraft in the 1960’s. Since its inception in 2017, SP400 and all subsequent SP and SPS models have set a new standard in low profile audio connectivity.

SP550-S is the TRS variant of the SP400/500. It features a slightly larger cable opening than the SP500 to accommodate balanced cables up to 5.6MM OD.
