Audix CBLM330 - Shielded CAT7 Interface Cable for M3 Microphone System (30 Meters)
The Audix CBLM330 is a high-performance Category 7 (CAT7) interface cable, specifically designed for the critical interconnection between the Audix M3 three-element ceiling microphone system and its connection unit or DSP console. Measuring 30 meters in length, this cable is more than just a standard network cable; it has been validated to carry high-fidelity analog audio signals from the microphone preamps in the ceiling to the equipment rack without any loss of quality or interference.
In professional installations where aesthetics and sound purity are paramount, the CBLM330 acts as the system's main artery. Its robust construction ensures that the M3 microphone's three independent audio channels travel with complete immunity to electromagnetic interference (EMI) and radio frequency interference (RFI), common in suspended ceilings with LED lighting or nearby electrical wiring. Its housing is made of Plenum- grade materials, meeting the strictest fire safety regulations for installations in air handling units.
Main features
-
High Fidelity Audio Transmission: Optimized to carry balanced analog signals from the three elements of the M3 microphone over long distances without signal degradation.
-
Superior CAT7 Shielding: Features four individually shielded twisted pairs, ensuring exceptional protection against crosstalk and external noise.
-
Plenum Certification (CMP): The cable sheath is designed with low smoke emission materials, making it safe and mandatory for permanent installations in ceilings and plenum chambers of commercial buildings.
-
Robust RJ45 Connectivity: Equipped with high-quality RJ45 terminations that ensure a firm fit and perfect electrical continuity with the M3 junction box and breakout cable.
-
Extended Length: Its 30 meters allow total flexibility to connect large conference rooms with remotely located control rooms or equipment racks.
Benefits of professional installation
Using the Audix CBLM330 dramatically simplifies cabling infrastructure in audiovisual projects. Instead of running three individual balanced XLR microphone cables through narrow conduits, this cable consolidates all transmission onto a single, manageable, and flexible CAT7 line. This not only reduces installation labor time but also minimizes cable clutter in cable trays, resulting in a tidier and easier-to-maintain environment.
Furthermore, as an official component of the Audix M3 ecosystem, it eliminates guesswork about impedance compatibility or shielding quality that might arise when using generic network cables, ensuring that noise rejection and vocal clarity remain at the studio-level quality promised by the M3 microphone.
Use cases
-
Corporate Videoconferencing Rooms: Ideal for connecting ceiling microphones in large boardrooms where the AV rack is located in a distant server room.
-
Auditoriums and Distance Education: Perfect for universities and training centers that require crystal-clear audio without interference from stage lighting or projectors.
-
Operating Rooms and Telemedicine: Its Plenum classification and high shielding make it suitable for hospital environments where reliability and safety are critical.
-
Courts and Justice Halls: Ensures accurate recording of legal proceedings through discreet and secure installation.
Frequently Asked Questions
Can I use a generic CAT7 cable instead of the CBLM330?
Although technically possible, the CBLM330 is guaranteed by Audix to meet the shielding standards required for the M3's analog audio. Generic cables may not have adequate shielding quality, which could introduce noise or interference into the audio signal.
Does this cable carry digital data or analog audio?
Within the context of the standard Audix M3 system, this cable is used to carry balanced analog audio over the twisted pairs. When used with the M3's Dante kit, the cable will carry a digital signal, for which it is also perfectly suited.
What does it mean for the cable to be "Plenum"?
This means the cable sheathing has special fire resistance and emits little smoke in case of combustion. It is a mandatory requirement in many building codes for cables passing through air plenums above suspended ceilings.
Project description
This 30-meter shielded Category 7 (CAT7) interface cable is specifically designed for interconnecting three-element ceiling microphone systems. The cable consists of four individually shielded twisted pairs with RJ45 connectors, optimized for transmitting analog or digital audio signals with high RF immunity. It features a Plenum-rated (CMP) jacket suitable for installation in air handling units (AHUs) of commercial buildings, meeting relevant fire safety regulations. The jacket color conforms to fixed installation standards.
