Usage Illustration
The system connects a Mixer/Preamplifier to the Transmitter's audio inputs. The Transmitter then wirelessly sends the audio signal to the Receiver, which is connected to headphones for personal monitoring.
Connection Flow:
- Mixer/Preamplifier [audio out] → Transmitter [audio in (XLR/6.35mm)]
- Transmitter [wireless signal] → Receiver [wireless signal]
- Receiver [headphone out] → Earphone
