GENERAL The FP12 is an in-line, battery-powered amplifier designed to accept a microphone- or line-level signal, bridge it, and produce a signal sufficient to drive headphones at very loud levels. The FP12 is ideal for anyone in the broadcasting, sound reinforcement or audio recording fields who has a need for headphone monitoring or checking microphone- or line-level cable runs. In addition, the FP12 can be used to provide multiple headphone feeds, a two-station intercom, extra power for existing headphone circuits, or a means of practicing electronic instruments through headphones.
