RE90B BW
Set it on the table and let it work. The RE90B is a half-cardioid boundary mic for conference rooms, distance-learning, and presentation spaces: internal EQ counters the baffle effect for a flat response, and EV's RF Shield technology keeps cell and RFI buzz out. The zinc die-cast body sits on a rubber pad that isolates surface vibration, and the cable routes through the tabletop, out of sight. Clean voice, high gain before feedback, nothing in the way.
Key features
Pick up the talker, not the room
Half-cardioid pattern lifts gain before feedback and suppresses ambient noise.
Stay clean near phones and screens
EV RF Shield technology rejects RFI and GSM interference.
Flat, natural voice
Internal equalization counters the boundary baffle effect across the band.
Built to live on the desk
Zinc die-cast body on a rubber isolation pad shrugs off surface vibration.
Install it out of sight
Route the cable through the tabletop and power from any 9: 52 VDC phantom supply.
Make it permanent
Internal fiber washers keep the surface isolation intact when the mic is permanently mounted.
