Audio systems can utilize which type of cables?

Audio systems can utilize any of the cable types mentioned because each is designed to meet different needs for communications and fire safety in various environments.

CMR (Communications Riser), CMG (Communications General), and CMP (Communications Plenum) cables are all rated for different installation scenarios. CMR cables are suitable for vertical spaces between floors, where fire resistance is necessary but not as stringent as in plenum spaces. CMG cables, while also providing good flame resistance, are intended for general use where fire safety ratings are less critical. CMP cables are designed for use in plenum spaces, which are more sensitive areas requiring the highest level of fire resistance.

The versatility of audio systems means that they can operate effectively with any of these cable types depending on the specific installation environment and fire codes applicable to that location. Therefore, the correct choice reflects the adaptability of audio systems to utilize any of these cable types based on their specifications and installation requirements.
