FAQ

Q: I'm having trouble reading some types of .wav files in EQ Filtering. Is there a fix?

A: Yes. If you are having trouble using .wav files in EQ Filtering, you are encouraged to download the "EQ Filtering WAV File DLL Update" from the download page. This DLL fixes a problem in EQ Filtering 2.0 and 2.1 where certain types of .wav files are read incorrectly.

Q: The EQ Filtering software is crashing, or is not working correctly. Is there an update avaible?

A: Yes. Version 2.1 of EQ Filtering is available for download to all S14 users from our download page.

This update addresses the following issues with EQ Filtering 2.0:

1) On some systems, filters applied to wav files that were less than a certain length sometimes caused the program to crash. This error has been corrected.

2) Stereo input files were output as mono files if the Mono Input To selector specified Left Only or Right Only. Stereo input files are now always processed and saved as stereo output files.

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.
