Title: Recording of my amp defect
Post by: soulsearchingsun on 01 March, 2012, 08:11:57 AM
Sine waves of 55 Hz, 440 Hz and 14080 Hz played through my Sony F519R amp. Right channel defective, noise added. Lower volume, partly nasty levels (near 0dB)!
edit: updated recording, old file was incorrectly recorded.
