SRTI Tech
MODEL 1145 PERFORMANCE SPECIFICATION
New subminiature condenser microphone for
professional applications. The extended frequency response and low frequency attenuation
are especially suitable for use with modern hearing aids. Effective damping of the
resonance reduces the possibility of feedback. Transducers represent the state of the art
in resistance to shock and vibration and in acoustic performance. A novel electret element
and integral preamplifier are included.
