The A 200 is a stereo personal sound amplifier for people who may sometimes need to rely on artificial assistance for their hearing. With stereo amplification via two integrated electret microphones, the user can clearly determine the direction of the sound source within an 8' to 10' radius. Dynamic headphone transducers ensure natural and transparent sound reproduction with optimum speech intelligibility. The A 200 features an auxiliary audio input for connecting an external microphone or infrared receiver.
