Audix CBLM320 - Shielded CAT7 Interface Cable for M3 Ceiling Microphone (20 Meters)
The Audix CBLM320 is much more than just a network cable; it's a critical infrastructure component specifically designed to ensure optimal performance of the Audix M3 ceiling microphone system. This 20-meter (66-foot) interface cable has been manufactured to the most demanding standards of professional audio engineering, ensuring that the signal captured by the M3 series tri-element microphones reaches its destination with crystal clarity and free from interference.
In modern audiovisual installations, cabling is often the weakest link, but with the CBLM320, Audix eliminates that concern. This cable is built with CAT 7 (Category 7) technology, which means significantly higher bandwidth capacity and shielding than standard Ethernet cables. Its design incorporates four individually shielded twisted pairs, providing exceptional immunity against radio frequency interference (RFI) and electromagnetic interference (EMI) caused by LED lights, Wi-Fi networks, air conditioners, and other electrical equipment found in suspended ceilings.
Safety is a top priority with this product. The CBLM320 features a Plenum -rated cover. This means it is coated with special flame-retardant and low-smoke materials, meeting the building and fire safety regulations required for installation in the plenum spaces of commercial buildings, corporate offices, and educational institutions.
Main features
-
Specific Engineering for Audio: Designed exclusively to interconnect the Audix M3 tri-element hanging microphone system with your DSP interface or console.
-
Superior CAT 7 Standard: Offers high-fidelity audio and data transmission performance thanks to its high-frequency (600 MHz) construction and robust shielding.
-
Interference protection: It has 4 shielded twisted pairs that ensure the audio signal remains pure, even in environments with high electrical noise.
-
Plenum Cover (CMP): Specialized cladding that meets safety codes for installations on roofs and air circulation spaces.
-
Extended Length: Its 20 meters in length allow for great installation flexibility in large conference rooms, auditoriums or lecture halls with high ceilings.
-
Professional Termination: Equipped with high-quality RJ45 connectors (specific configuration for M3 interface) that guarantee a secure and durable connection.
Benefits of professional installation
Using the genuine Audix CBLM320 cable provides peace of mind for both system integrators and end users. For installers, the Plenum rating simplifies compliance with building inspection regulations, eliminating the need for additional metal conduit in many cases. For users, the benefit is aural: the elimination of hum, static, and crosstalk ensures that video conferences and recordings sound professional and crystal clear, fully utilizing the M3 microphone capsule's capabilities.
Ideal use cases
-
Corporate Boardrooms: Where a clean ceiling aesthetic is vital and audio quality cannot fail during international calls.
-
University Auditoriums and Distance Education: To capture the voice of the teaching staff or students clearly in large spaces.
-
Convention Centers: Environments with a high density of electronic devices where CAT 7 shielding is indispensable.
-
Government and Judicial Facilities: Spaces that require strict compliance with security regulations and recording fidelity.
Frequently Asked Questions
-
Can I use a generic Ethernet cable instead of the CBLM320?
Although the connectors may appear standard, the CBLM320 is certified for the M3 system, ensuring the correct shielding and Plenum rating necessary for the safety and integrity of the system's specific analog or digital signal.
-
What does it mean for the roof to be Plenum?
This means the cable sheathing is treated to resist fire and not emit toxic fumes if burned. It is mandatory in most concealed spaces above suspended ceilings where air conditioning units circulate.
-
Does this cable transmit power (PoE)?
While the CAT 7 cable supports PoE, its primary function in the M3 ecosystem is the transmission of balanced audio signals and control between the microphone and the mixing interface.
Project description
Supply of high-performance audio interface cable for ceiling microphone system. The cable must be Category 7 (CAT 7) with four individually shielded twisted pairs for maximum EMI/RFI interference rejection. It must have a plenum-rated jacket for compliance with airspace safety regulations. The total length will be 20 meters (66 feet) and it will be terminated with RJ45 connectors optimized for connection between the Audix M3 microphone and its interface unit. Required reference: Audix CBLM320.
