LL1588 is a high - level general - purpose transformer which can be used for microphone or line input, for line output and for galvanic isolation. The windings are arranged to give perfect symmetry if the transfo rmer is used in phase splitting input applications. The two coils structure also greatly improves immunity to external magnetic fields from e.g. power supplies and motors. Primary and secondary windings are separated by electrostatic shields. The core is a high permeability mu metal core. The transformer is housed in a mu - metal can.

Received promptly Distributors in the USA were not responding to request to purchase Lundahl 1588 transformers. Found that DonAudio had them and I received them in a couple weeks. Cant ask for more!

Good transformers for interconnect. LL1588/LL1592/LL1590 are good transformers for audio signal, which can be used in high-end audio system. I used these transformers for galvanic isolation and filtering like Jeff Rowland. Distortion is extremely low and Lundahl is a serious supplier for such items. Transformers are still limited to low frequencies. These three transformers support about 7Vrms at 20Hz without visible distortion on a sinusoidal signal. For the perfectionist guys, I suggest adding an RC element to have flat bandwidth and good transient response, and maybe a series capacitor as well. The question remains: mu-metal core or cobalt-based core? Mu-metal seems safer...
