Heil Sound PR 40 Large-Diaphragm Dynamic Broadcast Microphone Chrome

Heil Sound PR 40 Chrome: A Mirror-Finish Broadcast Showpiece

The Heil Sound PR 40 Chrome is a large-diaphragm dynamic broadcast microphone that wraps the reference PR 40 platform in a mirror-polished chrome-plated body and grille. Underneath the gleaming shell it is a dynamic microphone, capturing sound through a moving coil rather than a powered capsule for rugged, hiss-free, broadcast-quality output. Studios and on-camera hosts choose the chrome edition when they want a mic that looks like a classic broadcast icon while performing to modern reference standards.

Large Dynamic Element with Neodymium Magnet

Behind the polished grille sits the same oversized dynamic element used throughout the PR 40 line, built on a low-mass diaphragm and an efficient neodymium magnet structure. The large coil responds instantly to transients while the neodymium magnet lifts output and expands dynamic range, so subtle detail and loud peaks are both preserved. That engineering gives narrators and broadcasters a full, articulate midrange with no outboard preamp or heavy processing required.

Widest 28 Hz to 18 kHz Response in the Line

This chrome PR 40 reproduces a 28 Hz to 18 kHz frequency response, the broadest of any dynamic in the Heil PR family. Frequency response describes the band of pitches captured evenly, and reaching to 28 Hz retains the low fundamentals and chest resonance that thinner mics roll off. A broadcaster gains a rich, authoritative sound, while the same microphone can double as a full-range instrument mic on bass or drums.

Cardioid Pattern and -40 dB Rear Rejection

The PR 40 Chrome employs a cardioid pattern with a rated -40 dB of rear rejection at 180 degrees off axis. Cardioid pickup emphasizes the front of the capsule and progressively rejects sound from the sides and rear, and this deep null is unusual for a dynamic microphone. In a reflective studio or a busy set, that rejection shuts out room echo and off-mic chatter so the primary voice stays clean.

148 dB Max SPL on Demanding Sources

A maximum SPL of 148 dB gives the chrome PR 40 the headroom to remain distortion-free on the loudest sources. Maximum SPL is the ceiling a microphone can take before the signal breaks up, and 148 dB is plentiful for kick drums, bass cabinets, and horns. The mirror-finish mic that anchors a broadcast can therefore step onto a drum kit or amplifier for a recording session without hesitation.

Internal Breath Filter Behind the Chrome Grille

The chrome head basket conceals dual mesh screens layered over an internal breath-blast filter mounted on the element. These barriers dissipate the burst of air from hard consonants before it reaches the diaphragm, controlling the plosive pops common in close vocal work. A voiceover artist can work close for an intimate, polished tone while keeping the sightline of the polished microphone uncluttered by an external pop screen.

Humbucking Coil, Steel Body, and Passive Setup

Beneath its plating the PR 40 Chrome is a rugged steel microphone with an internal humbucking coil for shielding, and it operates as a fully passive dynamic. The humbucking winding cancels hum from monitors, computers, and lighting, while the passive design means no phantom power is ever needed. Connect a balanced XLR cable to any preamp or interface and the chrome showpiece is ready, pairing vintage looks with genuine plug-and-play reliability.
