Operating Instructions

3. Acoustic Mode (Original Sound)
To switch to acoustic mode, press the 'Boot' button on the transmitter (TX) again after activating reverb mode. This mode captures the original, unprocessed sound without any effects or noise reduction.
4. Volume Adjustment
Use the 'Volume Up' and 'Volume Down' buttons on both the transmitter (TX) and receiver (RX) units to adjust the input and output audio levels respectively.
5. Real-time Monitoring
Connect headphones to the headphone output port on the transmitter (TX) to monitor your audio in real-time during recording.
