Sennheiser e 835-S-PTT – Cardioid Dynamic Vocal Microphone with Push-to-Talk Switch If you work in the audio industry and need a tool that ensures instant, controlled voice communication without compromising on sound quality, the Sennheiser e 835-S-PTT was designed exactly for you. This professional dynamic microphone with a cardioid polar pattern combines the legendary acoustic properties of the e 835 series with a practical Push-to-Talk mechanism, giving you full control over when your voice is transmitted. Product Features The Sennheiser e 835-S-PTT microphone stands out with a set of features that make it an indispensable tool in professional audio applications. The most important ones include: Push-to-Talk (PTT) Mechanism – allows for immediate microphone activation upon pressing the switch, providing full control over the start and end of voice transmission. An ideal solution in environments where precision and discretion in communication are paramount. Legendary Sound of the e 835 Series – the dynamic cardioid capsule delivers warm, detailed, and natural voice reproduction, which has been highly valued by professionals worldwide for years. Effective Ambient Noise Rejection – the cardioid polar pattern eliminates unwanted signals arriving from the rear and sides of the microphone, resulting in a clean and isolated signal even in noisy environments. Shock-Mounted Microphone Capsule – the vibration damping system minimizes noise transmitted through the hands, which is crucial during long sessions and intensive use. Feedback-Resistant Design – the microphone construction effectively reduces the risk of unwanted feedback, even in challenging acoustic conditions on stage or in the studio. Humbucking Coil – protects the signal from electromagnetic interference, ensuring stable and clean sound in any environment. Professional Control Over Voice Communication In the audio industry, where precision and reliability of communication are key, the Sennheiser e 835-S-PTT is the answer to the needs of the most demanding professionals. The Push-to-Talk mechanism allows for immediate voice transmission activation with a single button press, eliminating the risk of accidentally turning on the microphone and sending unwanted sounds to the PA system, stage monitoring, or transmission line. The dynamic capsule with a cardioid polar pattern was designed with maximum speech clarity in mind. The frequency response has been optimized for speech intelligibility, ensuring your voice cuts through the mix with natural warmth and detail, even under the most demanding acoustic conditions. The reduced proximity effect ensures a stable frequency response regardless of the distance between the mouth and the microphone – a practical solution appreciated by engineers working in dynamic environments where the speaker's distance from the microphone constantly changes. The high maximum sound pressure level (SPL) rating means the microphone handles even the loudest speeches and most expressive presentations with ease. Whether you are working with a charismatic presenter or managing an event with lively stage communication, the e 835-S-PTT will maintain signal purity without distortion or clipping. The built-in PTT switch operates intuitively and reliably – simply press the button to immediately transmit the signal to the system. Releasing the button automatically cuts the transmission. This solution is particularly valued in environments where discretion and control over communication timing are priorities: in command centers, radio studios, live broadcasts, and corporate internal communication systems. Applications Live sound reinforcement and stage event management – instant communication between the sound engineer and the technical team Studio production – precise communication between the sound engineer and performers Radio and television broadcasts – controlled microphone activation in talkback systems Corporate internal communication – information and conference systems Command centers and high-security facilities – discreet, controlled voice communication Fixed installations – communication systems in public, transportation, and industrial facilities Technical Specifications Transducer type: dynamic Polar pattern: cardioid Function: Push-to-Talk (PTT) – push-to-activate switch Manufacturer part number: 390020 Shock mount system: yes – reduces handling noise Feedback resistance: high – optimized construction Interference protection: humbucking coil Proximity effect: reduced – stable response at varying distances Intended use: voice communication, talkback, PA systems Materials and Construction The Sennheiser e 835-S-PTT microphone is built with a solid metal housing, which is a hallmark of the entire e 835 series.
