Feedback Controller — Stop Mic Squeal at Events
Microphone feedback ruins live events. A feedback controller (feedback eliminator) automatically detects and removes feedback frequencies before they squeal. Every professional DJ in India needs one. Available from Punishka Trading, Rohini, New Delhi.
Why Feedback Happens
- Hard reflective walls in indoor Indian venues
- Mics and speakers too close on small stages
- High volume demands from clients
- Multiple open mics active simultaneously
How It Works
Narrow notch filters automatically detect feedback frequency and cut it by 6-12dB in milliseconds. Units with 8, 12, or 16 bands handle multiple frequencies simultaneously — far faster than manual EQ adjustment.
Types
- Automatic: Real-time detection and notching. Best for live events.
- Semi-automatic: Run learning mode before the show. More transparent sound.
Setup Step by Step
- Insert between mixer main out and amplifier input
- Run auto/learning mode before show with all mics open
- Raise volume gradually — unit notches feedback automatically
- You can now run 3-6dB more gain before feedback vs without the unit
Feedback Controller vs Graphic EQ
Graphic EQ cuts broad bands — affects overall sound quality. Feedback controller uses narrow notch filters — only cuts the exact problem frequency. For professional events, use both: GEQ to tune the room, feedback controller as backup insurance.
