Pro Tips from Gabriel
As Musique Dépôt’s live sound specialist, here are my insider tips for maximizing your PSM300:
- Position your transmitter antenna at 45° for optimal coverage
- Use the RF frequency scanner during soundcheck AND before the show – RF environments can change dramatically
- Create a separate mix for your monitor feed – don’t just use the main mix
- Experiment with the high/low EQ to reduce ear fatigue during long sessions
