A transformer can virtually eliminate most types of noise generated when equipments are connected by preventing "ground loops". Balanced lines may be converted to unbalanced and vice versa. Signal voltage can be increased or reduced and unwanted loading effects can be removed by step up or down ratios. Mumetal cores ensure minimal distortion and a thick Mumetal can protects the transformer from hum fields. Multiple interleaved windings are used for high bandwidth and clean transient response. Faraday shields on most types ensure rejection of common mode noise. We offer a large range of products for recording, broadcasting, public address, instrumentation and equipment manufacturers as well as for replacement or maintenance.
