FAQ

Q: Where can I get additional ear canal tips for the S14 earphones?

Q: What sort of audio amplifier do I need?

A: The requirements for the amplifier are very modest. The transformer/earphone combination will require no more than 3 watts per channel, which is met by a large number of small audio amplifiers. Note that some amplifiers incorporate a loudness correction that effectively changes the frequency response along with overall gain as the volume is controlled. Two examples of amplifiers that have been used successfully are the Pyle Home PCA1 and the Dayton DTA-1.

Q: What is the attenuation provided by the S14 insert earphones?

A: See the Technical Note on Attenuation.
