EI28 AC AC Step Down Power Transformer Audio transformers are designed to modify the signal between various audio components in a sound system to provide the ideal sound balance. Typical audio transformer specifications include: Power Levels. Using an audio transformer allows for adjusting power levels between sound system components in order to balance the sound between amplifiers and speakers and avoid distortion. Frequency Response. Different equipment produces different ranges of sound frequencies. An audio transformer can help modify input and output in order to ensure transmission of the full range of audio being produced. Total Harmonic Distortion (THD). THD is caused by the combination of multiple layers of sound and power flowing through audio systems. Audio transformers help modify the distortion in order to improve sound quality. Insulation Resistance. Insulation resistance can cause loss of sound quality by interfering…
