Description

This PR77D is a demo unit in excellent, gently used condition, offering the full performance of Heil’s studio-grade dynamic microphone at a friendlier price point. Finished in purple, it’s a solid pick for broadcasters, podcasters, and home studio owners who want dependable, flat-response sound without the fuss of a condenser setup.

Large 1-inch, low-mass voice coil paired with a neodymium-iron-boron magnet for a clean, accurate signal
Cardioid pickup pattern with a refined phasing plug design delivering over -40 dB rear rejection at 180 degrees off-axis
Consistent tonal response even as the speaker moves around in front of the capsule
Built-in two-position switch to tailor frequency response: Voice mode rolls off at 120 Hz (-6 dB/octave) to tighten up speech, Music mode opens the full 60 Hz – 16 kHz range
Standard 5/8″-27 mic stand threading, made for boom arms or fixed bases rather than handheld use

Specs at a glance: dynamic element, 3-pin XLR output, cardioid pattern, 600 ohms balanced impedance, 24.5 oz weight, 148 dB max SPL, and -53.9 dB output level at 1 kHz.

Whether you’re tracking vocals, hosting a show, or need a mic that handles both speech and music duties without swapping gear, this PR77D demo delivers Heil’s signature broadcast sound at a lower cost of entry.
