Housed in RapcoHorizon's standard BLOX chassis, it delivers a compact, rugged form factor that holds up to the demands of touring and installed audio environments where unreliable speaker cable connections cost time and performance.\u003c\/p\u003e\u003cp\u003eWith two NL4MP Speak-On panel-mount connectors and four independent push-button switches — one per pole — technicians can isolate and test each conductor path individually, making it straightforward to identify intermittent faults, wiring errors, or damaged poles in multi-conductor Speak-On assemblies. Four red LED indicators give instant visual confirmation of continuity for each pole without requiring a separate meter or adapter.\u003c\/p\u003e\u003cp\u003eThe STBLOX is part of the broader Tester BLOX family, which also covers XLR, 1\/4-inch, and continuity testing scenarios using the same chassis and build standard. For production teams that need a consistent, no-frills cable testing toolkit across connector types, the BLOX series provides purpose-built tools that travel easily and perform reliably in rack rooms, stage setups, and permanent installs alike.\u003c\/p\u003e","brand":"RapcoHorizon Int RHC Holding","offers":[{"title":"Default Title","offer_id":52446677631160,"sku":"65335","price":26.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0871\/7382\/4696\/files\/65335_RAPHOR-STBLOX_ALT02.jpg?v=1783629072","url":"https:\/\/soundpro.com\/products\/rapcohorizon-stblox","provider":"SoundPro","version":"1.0","type":"link"}
