Line Output Transformer VTX-LOUT3

1 : 1: 1 : 1 150kΩ / 600kΩ 24dBu

High performance Line Input Transformer VTXLOUT3 – Used in high performance professional audio and hi-fi systems, line output transformers are small passive devices that help different pieces of audio equipment work well together.

• Reduce Hum and Noise:
  They pass the audio signal without a direct electrical connection, which helps stop annoying buzzing or humming sounds caused by ground loops.
• Help Equipment Communicate Properly:
  They adjust the signal so the output of one device matches the input of another, helping the sound stay clear and strong.
• Improve Sound Over Long Cables:
  They can connect different types of audio wiring (balanced and unbalanced) and help reduce interference and noise, especially when cables are long.
