Heil PR 77D Dynamic Microphone

The Heil PR 77D is a large-diaphragm dynamic microphone with a cardioid polar pattern for focused pickup. It includes a TT-ISO isolating desktop stand and an XLR-XLR cable so the system is ready for podcast, broadcast or recording work. The 600 ohm balanced output connects directly to professional preamps or interfaces.

Two-position voice and music filter

A switch selects between a 120 Hz roll-off for voice and a flat 60 Hz to 16 kHz response for music. The cardioid pattern gives 40 dB attenuation at 180 degrees off-axis to reduce room bleed. This replaces a fixed-filter dynamic mic when you need both speech clarity and full-range instrument capture.

Desktop stand with isolation base

The TT-ISO stand decouples the microphone from desk vibration without tools or permanent mounting. Connect the supplied XLR cable to the 3 pin output and position the side-address capsule toward the source. Ensure the preamp provides enough clean gain for the 600 ohm output or the signal will be too quiet.
