Classic FM is the term coined to describe FM technology where the decibel (dB) gain is constant.  Typically through classic FM technology the speaker’s voice is amplified by 10dB, regardless of the level of background noise.

Two Types of Classic FM

 

Fixed-Channel

• FM transmitters that are fixed on only one channel (FM frequency)
• May be selected because there are no other students in the school with a personal FM system or no classrooms with sound field systems.

Multi-Channel

• Channel can be changed on the FM transmitter
• Important when there are other students in the school using personal FM systems or sound field systems.
