Sabine SM820 Designed for single channels, Sabine’s 820 Series offers 8 patented FBX Filters, 20-bit digital resolution and increased headroom. Truly distinguishing the 820 from other feedback controllers is its ability to accurately control feedback during performances. Pre-owned, but in great condition.
The eight-filter SM-820 offers XLR connectors, has a mic preamp and selectable phantom power, is for use with balanced microphones.
The SM-820 provides more gain before feedback, increased sound clarity, and real-time automatic feedback control during setup and during the performance. The SM-820 automatically senses feedback and quickly places a narrow 1/10-octave adaptive digital filter directly on the resonating frequency. The 8 FBX filters are 10 times narrower than 1/3-octave graphic EQ filters (which are actually one full octave wide, spaced out on 1/3-octave centers), so the FBX provides more gain before feedback without a loss in sound quality. In fact, the FBX gives back more than 90 percent of the power lost with using a graphic EQ to control feedback.
The SM-820 offers a programmable noise gate and a filter locking feature that freezes the fixed filters created during setup so they won’t go deeper than their original setting. You can also switch from 1/10-octave filters to wider 1/5-octave filters for more robust feedback control. Six FBX-SOLOs can be mounted in a single space rack tray. FREE SHIPPING
The SM-820 is perfect for wireless mics, monitors, acoustic/electric instruments, harmonica mics, multi-mic locations like conference rooms and courthouses — wherever there’s an open microphone. It’ll improve sound systems in churches, theaters, schools, hotels and conference rooms – and fit into any budget.
