It might be worth adding that you should turn the amps down to minimum before starting the test tone, then slowly turn one up. If you start to hear distortion you've gone too far... Sine waves can be dangerous for speakers, especially high frequency ones, as (cheaper speakers especially) are not typically very tolerant to the constant current that a sine wave produces. I'm guessing the sb test tone is 1kHz though, which shouldn't be too bad as it'll go through the woofer in most speakers. -- bludragon ------------------------------------------------------------------------ bludragon's Profile: http://forums.slimdevices.com/member.php?userid=1530 View this thread: http://forums.slimdevices.com/showthread.php?t=18863 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
