The Shure SM90 is a vintage, surface-mounted omnidirectional condenser boundary microphone released as an omni counterpart to the SM91.
Overview & Specs:
- Type: Permanently-biased condenser, boundary/surface-mount
- Polar Pattern: Hemispherical omnidirectional (360° pickup above the mounting surface)
- Frequency Response: 20–20,000 Hz
- Powering: Requires Shure external preamplifier (like the model 94A1670/preamp) running on dual 9V alkaline batteries or 11–52V DC phantom/simplex power
- Key Features: Boundary effect doubles sound pressure (+6 dB sensitivity, ~3 dB background noise rejection), switchable low-frequency cutoff on preamp.
Common Uses:
- Kick Drum: Placed inside or just in front of the shell for a punchy, direct low-end attack.
- Room/Ambience: Laid or mounted on floors, walls, or grand piano undercarriages for natural "in-the-room" capture.
- Surfaces: Conferences, theater stages, or broadcast boundary applications.
