Phonic's i7100 Feedback Silencer features a 32-bit digital feedback eliminating DSP and 24-bit A/D and D/A converters with a 256/512 times oversampling rate. It provides a larger suppression range and a more refined feedback seeking method than other similar products.
Features
High headroom and resolution with 24-bit A/D and D/A converters and 256/512 times oversampling
Automatically searches for feedback in up to 12 frequencies per channel and intelligently removes it
24 fully programmable Parametric Filters that can be set manually
Single-Shot Mode automatically seeks and destroys feedback, locking the filters until manually reset
Auto Mode constantly monitors the mix and automatically resets the filters
Manual Mode provides each channel with up to 12 fully parametric filters, including frequency, bandwidth, and gain
Single-Shot, Auto, and Manual modes can be assigned to each individual filter
Internal 32-bit processor with 48 kHz sampling rate
Balanced XLR and 1/4" TRS connectors for inputs and outputs
20 user-definable presets, as well as 20 factory presets
A 10-segment LED meter per channel for displaying output levels
Immediate display and parameter tuning
Internal power supply design for professional applications.
Current settings are automatically saved and stored, even after power is off
Key-locking of device provides security against accidental alteration of settings
