PROEL CMT8 - 8 Pair Multipolar Audio Cable with Full Shielding
The PROEL CMT8 is a high-end professional solution designed for sound engineers, installers, and technicians seeking absolute reliability in analog audio signal transmission. Part of Proel's acclaimed CMT series, this multi-core cable stands out for its superior engineering, designed to withstand the demands of live performance and deliver maximum clarity in studio environments.
This cable consists of eight balanced pairs , each meticulously insulated and 100% shielded. Its performance is key to using XLPE (cross-linked polyethylene) for the insulation of the inner conductors (red and black coded). Unlike standard insulation, XLPE offers a lower dielectric constant, resulting in lower capacitance and, therefore, improved high-frequency response over long distances. Furthermore, this material is extremely heat-resistant, preventing the insulation from shrinking or deforming during the connector soldering process.
To simplify the technician's work, each pair has an individual, numbered, and color-coded cover on both sides. This eliminates the need for continuity testers during assembly, drastically reducing cable assembly time and minimizing the risk of phasing errors. The entire assembly is protected by a specially formulated S-PVC (soft PVC) outer jacket. This material is not only abrasion-resistant, protecting the cable from being stepped on and rubbed on stage, but also maintains exceptional flexibility even in adverse temperature conditions, allowing the cable to be wound and unwound without developing "memory" or distorted shapes.
Main features
-
Superior signal integrity: Thanks to the low capacitance XLPE insulation, the signal remains crystal clear and without treble loss, ideal for long runs.
-
Quick identification system: The pairs are individually numbered and feature distinctive colors, simplifying instant visual identification without additional tools.
-
Robust and flexible construction: The abrasion-resistant PVC cover ensures a long lifespan on demanding tours, while its flexibility makes it easy to handle and store on reels.
-
Total shielding: 100% shielding on each pair ensures absolute rejection of electromagnetic interference (EMI) and radio frequency noise (RFI), crucial in scenarios with high electrical load.
-
Ease of soldering: The internal materials withstand high temperatures, allowing precise tinning and soldering without damaging the conductor insulation.
Benefits for the professional
The PROEL CMT8 is designed to save time and money. Its identification system eliminates common wiring errors that often require hours of troubleshooting. For rental companies, the durability of the abrasion-resistant PVC means a more cost-effective long-term investment, as the cable withstands the wear and tear of daily setup and teardown. For the studio engineer, the low capacitance ensures that the original tone of instruments and microphones reaches the mixing console without coloration or background noise.
Use cases
-
Stage hose making (Snakes): Ideal for creating custom 8-channel stage boxes for drums or wind sections.
-
Fixed installations in studios: Perfect for wiring recording rooms (Live Rooms) to the control room, passing through conduits or false ceilings thanks to its robustness.
-
Effects and amplification racks: Very useful for cleaning up the cabling at the back of complex racks, unifying 8 signal lines into a single, tidy cable.
-
Monitoring systems: Excellent for sending signals to headphone amplifiers or in-ear monitors on stage.
Frequently Asked Questions
Is the cable suitable for both microphone and line signals?
Yes, the cable's impedance and construction are perfect for transmitting both microphone-level and balanced line-level signals with complete fidelity.
What is the outer diameter of the hose?
The hose has an approximate diameter of 13.40 mm, making it compatible with most standard gland fittings and multipin connectors on the market.
Do individual pairs have their own cover?
Yes, each pair is insulated with its own numbered PVC cover, allowing the pairs to be separated at the connector end (fan-out) in a clean and protected manner without the need for additional heat shrink tubing in most cases.
Is it difficult to peel for welding?
No, the XLPE material and the arrangement of the drainage threads are designed for quick stripping and preparation, making the installer's job easier.
Project description
8-pair balanced analog audio multi-core cable, CMT series model. Each pair consists of 26 AWG (0.14 mm²) flexible copper conductors with low-capacitance, high-thermal-resistance cross-linked polyethylene (XLPE) insulation. Each pair is individually 100% shielded with tape and features a 24 AWG (0.22 mm²) tinned copper drain wire, as well as an individual numbered and color-coded PVC jacket. The overall outer jacket is made of flexible, abrasion-resistant black S-PVC with a total diameter of 13.40 mm. Nominal impedance is 100 ohms and conductor-to-conductor capacitance is 52 pF/m.
