Because of their high cost, transformers have become increasingly unattractive to the Hi-fi industry over the decades. But especially in today’s world, where interference (WLAN, mobile phone, etc.) is a serious problem, transformers offer great advantages in connection technology. The devices are galvanically isolated from each other, the connections are ungrounded and offer high immunity to interference. Both connectors, XLR and RCA (optional), are supplied in parallel via the output transformers.
