Audio Monitoring

The Stereo input has two sockets wired in parallel. This allows you to connect a

pair of headphones to monitor the input levels, however this will increase the

loading on your audio device and may not be suitable for all audio devices. The

Audio monitoring facility is not available for use with the internal microphone.

Because the human body does not respond to E-Stim Signals above 6Khz,

audio signals with a substantial high frequency component may not always

produce the result that you would expect. For the same reason low frequency

signals below 50Hz will be poor sources for stimulation.

The ideal input level in both the microphone and stereo input modes should

result in the maximum input LED flashing from time to time indicating a peak. A

signal that results in the 100% LED being illuminated continuously will cause

distortion and not allow the full output range to be utilized.
