Headphone Amplifier

In a noisy contesting environment, it’s handy to have three controllable audio outputs.

  • the Operator with a headset to exclude background (room) noise
  • the Logger with a headset¬† to exclude background (room) noise
  • the casual Listener monitoring the QSOs

By connecting a headphone amplifier, such as the Behringer HA400 or equivalent, each person can control his/her audio volume. The Listener output can be connected to a speaker without bothering the other two.
