Digital Audio Transformers
Commercial transformers exhibit tremendous differences in parameters and performance. Digital audio transformers substantially improve common mode noise rejection and EMI emission. Second order effects such as pulse aberration and saturation greatly influence waveform fidelity. AES/EBU receivers exhibit jitter that is a function of the transformer CMRR and capacitance. Professional, broadcast and high resolution applications need maximum CMRR to minimize recovered clock jitter in the presence of noise. High quality transformers offer cost effective improvements in product design.
The requirement is to have substantially improved transformer performance by using the highest quality materials, special winding techniques, and 100% hand-winding and testing. The transformers’ pulse aberration, jitter, and high frequency common mode interference rejection need to be15-36 dB better than competitive products. MH&W offers the highest quality materials to achieve these requirements. The TDK H5C2 material is particulary dominent in this field in core shapes EP10, EP13, ER9.5/5 and ER11/5.
