Audix CBLM3300 - CAT7 Plenum Cable Reel for Installation (300m)
The Audix CBLM3300 is a high-performance Category 7 (CAT7) bulk cable reel, specifically designed to meet the demanding needs of professional audio installations, and in particular, the Audix M3 ceiling microphone ecosystem. With a total length of 300 meters , this cable provides integrators and technicians with the flexibility to create custom cable runs in large venues, ensuring flawless signal transmission from the source to the processing equipment.
Unlike standard network cables, the CBLM3300 has been validated to carry high-fidelity analog audio signals through its twisted-pair architecture without loss of quality or interference. Its robust construction includes a Plenum- rated jacket, making it the safe and mandatory choice for installations in suspended ceilings and air handling units in commercial buildings, meeting the strictest fire safety regulations.
Main Features
-
High Performance CAT7 Certification: Exceeds conventional bandwidth standards, delivering a bottleneck-free data and audio highway.
-
Superior Shielding: Features 4 individually shielded twisted pairs. This design is critical for the Audix M3 microphone, as it prevents crosstalk between analog audio channels traveling through the same cable.
-
Plenum Cover (CMP): Special low toxicity and flame retardant coating, designed to be legally installed in plenum spaces (air ducts and suspended ceilings) of offices, schools and auditoriums.
-
Length of 300 Meters: Supplied on a large capacity reel, ideal for large-scale projects where it is necessary to cut the cable to the exact length to avoid excess or unnecessary splices.
-
Optimized for Analog Audio over CAT: Although it is a network cable, its impedance and shielding are verified to maintain the integrity of analog microphone signals over long distances.
Benefits for the Installer and the End User
Using Audix CBLM3300 cable ensures peace of mind in critical projects. By using the manufacturer's specified cable, absolute immunity to radio frequency interference (RFI) and electromagnetic interference (EMI) is guaranteed—vital in corporate environments saturated with Wi-Fi and mobile signals. For installers, working with a 300-meter reel allows for optimized material usage, adapting each run to the exact layout of the room, whether it's a small huddle room or a large conference center.
Use Cases
-
Audix M3 Ceiling Microphone Installation: Connection between the microphone junction box and the Dante interface (such as the Audix DN43) or analog breakout cable.
-
Conference Rooms and Boardrooms: Environments where clean aesthetics are essential and cabling must be hidden in the ceiling.
-
University Auditoriums and Distance Education: Large spaces that require cable runs of more than 50 or 100 meters without signal degradation.
-
Government and Corporate Buildings: Projects that strictly require Plenum-rated cabling per safety regulations.
Frequently Asked Questions
Does this cable come with the RJ45 connectors already installed?
No, the CBLM3300 is a bulk cable reel. The installer must cut the cable to the required length and terminate it with high-quality shielded RJ45 connectors at the installation site.
Can I use this cable for regular data networks?
Yes, being a CAT7 cable, it is fully compatible with high-speed Ethernet networks, exceeding the specifications of CAT5e and CAT6. However, its cost and shielding make it "premium" for sensitive audio applications.
Why does it need to be Plenum?
In most modern building codes, any cable running through the space between the structural ceiling and the suspended ceiling (plenum space) must be plenum-rated. This ensures that, in the event of a fire, the cable does not emit toxic fumes and slows the spread of the fire.
Project description
Supply of bulk Category 7 (CAT7) cable on a 300-meter reel, model Audix CBLM3300. The cable must have four individually shielded twisted pairs to ensure immunity to crosstalk and EMI/RFI interference. It must have a Plenum-rated (CMP) jacket suitable for installation in air handling units and suspended ceilings. Specified for interconnecting tri-element ceiling microphone systems and transmitting analog or digital signals over long distances.
