Video & Balanced Stereo Audio Isolation Transformer

The TR-3 is a high-performance isolation transformer for composite video and balanced stereo signals. The TR-3 provides complete isolation between devices to eliminate hum, ground loops and DC offsets that can degrade the audio and video quality.
 

TR-3 features include:

  • Video Bandwidth - <10kHz to 5.8MHz (−3dB).

  • Audio S/N Ratio - −83dB to +4dBu @1kHz.

  • Audio & Video Input & Output External Ground Terminals.

  • Audio & Video Grounding Options - DIP−switch selectable.

  • Passive - No power required.

  • Compact Kramer TOOLS™ - 3 units can be rack mounted side−by−side in a 1U rack space with the optional rack adapter.
