Description
Product Overview
The Heil PR 35 is a professional-quality dynamic handheld microphone specifically engineered for live vocal sound reinforcement, studio recording, and high-volume stage applications. Featuring a large 1.5-inch diaphragm dynamic element, the PR 35 delivers the clear, natural, and wide frequency response of a studio condenser microphone alongside the rugged durability and high isolation of a dynamic capsule.
Designed to overcome demanding acoustic environments, the PR 35 features a multi-position low-end roll-off switch (allowing users to select between a full flat response or an 80 Hz high-pass filter) to eliminate unwanted low-frequency rumble and proximity boominess. Its supercardioid polar pattern provides an exceptional -35 dB of rear noise rejection at 180° off-axis, making it an outstanding choice for vocalists needing maximum gain-before-feedback on loud stages with high monitor or instrument bleed. To ensure comfort and longevity during live performances, the microphone is finished in a durable rubberized exterior coating that enhances grip while suppressing handling noise.
Key Features
-
Large 1.5” Dynamic Diaphragm: Delivers an ultra-wide, linear frequency response (40 Hz – 18 kHz) that provides pristine condenser-like articulation and smooth vocal presence.
-
Multi-Position Low-End Roll-Off Switch: Built-in high-pass filter allows switching between UP (40 Hz – 18 kHz) for full-range response and DOWN (80 Hz – 18 kHz) to eliminate low-frequency rumble, stage thuds, or excessive proximity effect.
-
High Rear Noise Rejection (-35 dB): Supercardioid pickup pattern delivers powerful -35 dB rejection at 180° off-axis, isolating live vocals from stage volume, monitor bleed, and drum bleed.
-
High SPL Capacity (140 dB Max SPL): Handles high sound pressure levels effortlessly without distorting, making it equally effective on powerful lead vocalists and loud instruments.
-
Durable Rubberized Protective Coating: Rubber-coated exterior finish offers a comfortable grip, extra physical durability, and additional suppression of handling noise during live stage performances.
-
Plosive and Handling Protection: Internal shock mounting combined with acoustic damping shields the element from mechanical shock, vibration, and vocal plosives.
-
Passive Dynamic Design: Requires no phantom power or external preamp boosters, operating via a standard 3-pin XLR connection.

Product FAQs
Question: How does the low-end roll-off switch work on the Heil PR 35?
Answer: The PR 35 includes a multi-position switch located on the microphone body. When set to the UP position, the microphone delivers a full 40 Hz – 18 kHz flat frequency response. When switched to the DOWN position, an 80 Hz high-pass filter is engaged to reduce low-frequency rumble, stage vibration, and vocal proximity effect.
Question: Does the Heil PR 35 require phantom power?
Answer: No. The Heil PR 35 is a passive dynamic microphone and does not require +48V phantom power. Connecting it to phantom power will not damage the microphone, but it runs strictly off dynamic element principles.
Question: How does the Heil PR 35 perform on loud stages?
Answer: The PR 35 excels on loud live stages thanks to its tight supercardioid pattern and exceptional -35 dB rear rejection at 180° off-axis. It isolates the lead vocal, minimizes stage bleed from drums and guitar amplifiers, and allows high gain-before-feedback through stage monitors.
Question: What is the difference between the PR 35 and the PR 37?
Answer: While both are premium dynamic vocal microphones, the PR 35 includes a physical low-pass roll-off filter switch, a rubberized exterior coating, and a warm, wide response. The PR 37 is the next evolution in Heil’s vocal line, offering higher output level (-48.9 dB vs -52.9 dB), higher rear rejection (-40 dB), and an upper midrange voiced to cut through dense live mixes without needing manual EQ adjustments or filter switches.
