The Grimm Audio TPR Cable – 40 Metres is a premium bulk-cable solution for larger studio installations, mastering rooms, theatre systems, post-production facilities and high-performance home-cinema projects. Supplied as one continuous, un-terminated 40 m length, it gives engineers and installers the flexibility to create custom balanced XLR lines, long patchbay runs, equipment looms and AES/EBU digital connections exactly where they are needed.
TPR — Twisted Pair Reference — was developed for the renovated Wisseloord Studios and is engineered for demanding professional audio environments. Its symmetrical twisted-pair construction, 89% shield coverage and conductive polymer layer are designed to achieve high RF immunity and very low microphonics. This makes TPR particularly relevant for longer signal paths running near rack equipment, switching power supplies, network hardware, lighting systems and other potential sources of electrical interference.grimmaudio+1
With a 110 Ω characteristic impedance, Grimm TPR is an excellent choice for professional AES/EBU digital audio connections. At the same time, its balanced, shielded construction makes it highly suitable for critical analogue microphone, line-level and patchbay applications. The 40 m format is ideal for control-room-to-live-room cabling, theatre racks, fixed AV installations, mastering suites and custom home-cinema signal routing. Its 24 AWG conductors, 5.5 mm diameter and 55 mm minimum bend radius combine durable installation quality with practical handling and professional termination options.
Installation note: For permanent installations in theatres, public buildings or commercial venues, please verify all local fire-safety, building and installation requirements before use.
