Ideal for use in performance venues, broadcast houses, and broad-scale AV installations, the Jensen Transformers Iso-Max DIN-PB is a passive, single-channel universal line isolator which can be inserted anywhere in the signal chain to prevent and eliminate hum and buzz caused by ground loops. Designed to work with professional, balanced audio systems, it is also capable of attenuating electromagnetic interference (EMI) and radio frequency interference (RFI) problems. The unit is plug-and-play with no power required, and snaps into place onto a standard 35mm DIN rail, for easy installation in a NEMA electrical enclosure.

The DIN-PB features a specially designed Jensen multi-tap isolation transformer that provides galvanic isolation between the input and output, reducing common-mode noise by as much as 125 dB. The unit delivers a flat frequency-response from 1 Hz to 200 kHz, and can withstand signals in excess of +24 dB, without discernible distortion.

Connections to and from the Jensen Transformers Iso-Max DIN-PB are made via removable screw-down wire terminals. The module comes equipped with a gray, molded assembly made from UL94-VO flame-retardant Noryl.
