Audio systems can utilize ___ cables.

Audio systems can utilize CMG (Communications Multipurpose General) cables because these cables are specifically designed for general use in commercial environments where low smoke and flame resistance are required. CMG cables are suitable for in-wall use and maintain a balance between flexibility and durability, making them ideal for audio applications where mobility, installation flexibility, and safety from fire hazards are essential.

In contrast, CMR (Communications Multipurpose Riser) cables are primarily intended for vertical spaces between floors and are designed to prevent the spread of fire from one floor to another. CMP (Communications Multipurpose Plenum) cables, which are rated for use in spaces used for air circulation for heating and air conditioning (plenum spaces), have a higher flame resistance and generate less smoke when burned, making them highly suitable for environments where airflow is critical.

While all three types of cables can technically be used for audio systems under the right circumstances, CMG cables are the most common choice for typical audio installations due to their balance of safety and versatility in various environments.
