RTI Tech
MODEL 2040 PERFORMANCE SPECIFICATION

New subminiature transducers for applications demanding the ultimate in vibration immunity and ultra small size such as hearing aids worn in the ear. This is the Zero G line which incorporates a novel diaphragm construction which reduces interference caused by mechanical vibration. The wide frequency range permits improved voice intelligibility and an internal preamp facilitates applications.
