The TR-1A Balanced Mono Audio Isolation Transformer from Kramer is designed for use with balanced mono audio signals. This unit provides complete isolation between devices, thus eliminating hum, ground loops, and DC offsets that can degrade audio quality. It is well suited for use in broadcast and production facilities, staging & field work, duplication studios, and other similar settings and uses.

The transformer features external input and output ground terminals. Moreover, grounding options can be selected with a dip switch. The unit receives power passively and no power supply is required.
