For the audio signal transformer, the primary secondary end uses two sets of winding methods, which can be used in series or in parallel. Flexible application.
This audio transformer adopts EE25mm permalloy sheet with imported content of more than 80% and high-purity oxygen-free copper wire. The audio signal is well isolated and converted, the response frequency is extremely wide, and the spectral curve is straight. Suitable for high quality audio transmission, enthusiast DIY, preamp input and output impedance matching, professional audio field, balanced unbalanced conversion.
