SquarePlug
the most comprehensive range
of low profile Audio connectors
in the industry
SquarePlug offers the most comprehensive range of low profile audio connectors in the industry. The product line consists of 11 different models, set to cover virtually every possible application where low profile balanced and unbalanced audio cabling is required. Besides the obvious small form factor competitive advantage, SquarePlug connectors provide a set of functionalities not found elsewhere, such as:
An improved strain relief design preventing any axial AND lateral cable movements, thus keeping the solder joints completely stress-free
An elegant cable identification/tracing system built around a set of colored screws — 2 screws per connector, 10 different colors — that can be retrofitted on all SP connectors. 55 distinct combinations can be built this way
SquarePlugs are protected by domestic and foreign patents

FAMILY
SP SERIES
Low Profile 1/4″ Mono and Stereo Right Angle connectors
SP400
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
SP500
SP500 is the twin brother of the SP400 except for that it allows for larger diameter cables to be used
SP600
SP600 is the newest member of the SP series. Designed to work with cables up to 6.2mm OD, it’s the perfect choice for instrument cables assemblies
SP550-S
SP550-S is the TRS variant of the SP400/500. It features a slightly larger cable opening than the SP500 to accommodate balanced cables
KEY FEATURES OF THE
SP SERIES
Low profile design for highest packing density
Unmatched strain relief and emi protection: the SP series features a flat smooth cable channel that’s perfectly snug with the right sized cable providing equal pressure around the entire cable, thus insuring proper shielding continuity and effective strain relief action
Solder tabs for tip, ring and sleeve connections for quick and easy soldering and desoldering
Serviceable, all-metal construction
Available in silver and all-black finish
SPS SERIES
Low Profile 1/4″ Mono and Stereo Straight connectors
SPS4
SPS4 is the lowest profile 1/4″ straight connector with strain relief in the industry. It features a proprietary two-screw cable clamping mechanism that can be retrofitted with a set of anodized screws to provide the most comprehensive color coding identification system found on any connector on the market
SPS5
SPS5 is identical in every point to the SPS4 except that it accommodates larger diameter cables
SPS6M
SPS6M is intended to be used on instrument cables, where small size is not imperative. It offers the same design as the SPS4/5 connectors, including the signature circular groove for increased grip as well as the 2-screws strain relief / color coding system
SPS6-S
SPS6-S is our straight TRS plug similar in design to its SPS4/5 TS counterparts. It can accommodate balanced cables with an OD up to 6.5mm, and pairs perfectly with our short body XLR plugs for 1/4″ TRS – XLR cables assemblies
SPS7-S
SPS7-S was specifically designed for Y or insert cables assemblies. It features a proprietary oblong shaped ring that maintains the cables parallel to each other, thus preventing any stress build-up on the solder joints induced by the cables tendency to fold/twist on one another
KEY FEATURES OF THE
SPS SERIES
Low profile design for highest packing density
—
Solder tabs for tip, ring and sleeve connections for quick and easy soldering and desoldering
Serviceable, all-metal construction
Available in silver and all-black finish
SPX SERIES
Low Profile True Heavy Duty – THD – XLR Connectors
SPX-M
SPX-M is a 3-PIN male XLR connector unlike anything else on the market. Built equally for studio and stage applications, SPX-M/F is designed to deliver high performance, maximum reliability and unmatched functionality in a small package. It’s the perfect solution for low clearance situations and/or when a true heavy duty connector is required
SPX-F
SPX-F is the female variant of the SPX-M
KEY FEATURES OF THE
SPX SERIES
25% shorter than the standard XLR design
All-metal THD – True Heavy Duty – construction built to withstand the rigors of daily abuse and touring
Ergonomic design featuring knurled shoulders for maximum grip strength
Secure cable clamping provided by a chuck type strain relief that allows higher pull-out force
Quick and easy assembly using only 4 parts and no screws. Side screws for color coding only
Retrofittable cable identification/tracing system via a proprietary set of color coded screws common to both the 1/4″ and XLR connectors. SquarePlug is the only brand that provides such a unique and elegant solution to ID/trace any type of cable assembly through 55 distinct combinations
