The Model EJ-10 is a multi-input adapter that accepts line or speaker level input from a variety of audio/video devices, including an analog 4-wire telephone. It then inserts the signal into an existing PA or music system, while providing the necessary matching and isolation protection for the sound system and telephone. The EJ-10 provides everything required to connect a telephone, VCR, phonograph, tape player, guitar, projector, PC, CD player, DVD player, radio or other audio source, to the microphone input of a PA system. Virtually any input signal can be accommodated, including a speaker level input of up to 10 watts.
