Audix CBLM310 - 10 Meter CAT7 Interface Cable with Plenum Cover for M3 Series Microphones
The Audix CBLM310 is a high-performance interface cable specifically designed to meet the demands of professional audio installations. This 10-meter CAT7 cable is not a generic network cable; it has been selected and validated by Audix to ensure absolute signal integrity in their ceiling microphone systems, especially the acclaimed M3 Series . Its robust construction and advanced technical specifications make it the critical link for maintaining balanced, noise-free, studio-quality audio in corporate and educational environments.
In the world of audiovisual integration, the quality of the cabling is just as vital as the microphone itself. The CBLM310 stands out for its ability to protect analog audio signals traveling through its twisted pairs. Thanks to its superior shielding, this cable acts as an impenetrable barrier against electromagnetic interference (EMI) and radio frequency interference (RFI), common in suspended ceilings teeming with electrical wiring, air conditioning systems, and Wi-Fi networks. By using this original cable, you ensure that the M3 microphone's tri-element pickup reaches the DSP or mixer with crystal clarity.
A key feature of the CBLM310 is its Plenum classification. This safety feature is mandatory in many modern building codes for cables installed in air handling units (such as suspended office ceilings). The Plenum cover is made of special flame-retardant materials that emit minimal smoke and toxicity in the event of a fire, meeting the strictest safety standards. This not only protects the technical installation but also ensures regulatory compliance in public tender projects and large corporations.
Main features
-
High Fidelity Audio Transmission: Designed to carry balanced audio signals without loss of high frequencies or introduction of floor noise.
-
Advanced CAT7 Shielding: Features 4 individually shielded twisted pairs, providing exceptional immunity against ambient electrical noise.
-
Plenum Safety (CMP): Special coating suitable for permanent installations in ceilings and air chambers, complying with rigorous fire safety codes.
-
Professional RJ45 Connectors: High-quality male-to-male terminations that ensure a firm fit and a long-lasting connection, preventing accidental disconnections after installation.
-
Optimized Length: Its 10 meters (33 feet) offer the necessary flexibility for routes from the center of the room to the equipment rack or wall-mounted junction box.
Benefits for the integrator and the end user
For the audio-visual integrator , the CBLM310 eliminates uncertainty. By using the manufacturer's specified cable, common problems such as ground loops or hum that often occur with lower-category CAT cables (like unshielded CAT5e or CAT6) when used for analog audio are avoided. This translates to less troubleshooting time on site and faster project delivery.
For the end user , the benefit is seamless communication. Whether in a critical video conference with the board of directors or in a remote class, the voice is transmitted naturally and without sound artifacts, allowing the technology to become invisible and the meeting to flow without technical distractions.
Use cases
-
Videoconference Rooms: Trunk connection between the Audix M3 ceiling microphone and the breakout interface that feeds the audio processor.
-
Auditoriums and Distance Education: Facilities in universities where cabling must run long distances across the ceiling through areas with high fluorescent or LED lighting.
-
Operating rooms and Telemedicine: Environments where signal clarity is critical and interference from nearby medical equipment is not tolerated.
-
Corporate Boardrooms: Spaces that require a clean aesthetic finish and strict compliance with building safety regulations (Plenum).
Frequently Asked Questions
-
Can I use this cable for internet data networks?
Yes, being a CAT7 cable it meets and exceeds data standards, but its cost and construction are specifically optimized for sensitive audio applications and powering devices like the M3 microphone.
-
Is it compatible with microphones other than the M3?
The cable is a standard RJ45 CAT7. It can work with any system (such as Dante or AES67, or analog audio over CAT) that requires this type of connection, provided the equipment pinout is verified. However, it is certified for the Audix M3 series.
-
Why do I need a Plenum cable?
If you are going to run the cable through the space between the false ceiling and the floor slab (plenum), fire regulations usually require the use of cables with this covering to prevent the cable from spreading the flame or generating toxic smoke through the air ducts in case of fire.
-
Does this cable include the breakout to XLR adapter?
No, the CBLM310 is the 10-meter male-to-male extension cable. The breakout cable, which converts the RJ45 to XLR connectors, usually comes with the microphone or is purchased separately as a termination accessory.
Project description
This 10-meter (30-foot) Category 7 (CAT7) shielded interface cable is designed for transmitting balanced analog audio signals in installed microphone systems. It features four individually shielded twisted pairs for maximum rejection of electromagnetic and radio frequency interference (EMI/RFI). Both ends are terminated with high-quality RJ45 male connectors. The outer jacket is Plenum-rated, meeting safety standards for installation in air handling units in commercial buildings. Specifically validated for use with the Audix M3 ceiling microphone system.
