The DM-202 K from RCS Audio-Systems is a dynamic handheld microphone with a cardioid polar pattern, designed for speech and vocal applications. It features a feedback-reduced radiation characteristic, making it particularly suitable for live events, stage use, and rehearsal rooms. The integrated wind and pop shield minimizes unwanted air and plosive sounds, improving sound quality when used in close proximity to the microphone. Operation is via a noiseless on/off switch built into the grip, equipped with a locking screw, enabling disturbance-free actuation. The microphone is fitted with an unbalanced 3.5 mm jack plug, allowing universal use with standard audio and PA systems. The package includes a 4-meter connection cable, providing sufficient freedom of movement.

Applications
This microphone is designed for speech transmission and vocal applications. The cardioid polar pattern ensures that sound is primarily captured from the front direction, while sound from the sides and rear is attenuated. This reduces the likelihood of feedback, especially in acoustically demanding rooms. It is therefore suitable for professional stage use as well as for use in rehearsal rooms, conferences, or presentations.

Functions and Equipment in Detail
The integrated wind and pop shield protects against airflows generated during speaking or singing and prevents sharp plosive sounds such as p and t. The on/off switch in the grip is mechanically stable and features a locking screw to prevent accidental activation. The combination of compact design and ergonomic grip ensures comfortable handling over extended periods.

Technology Explained Simply
The microphone operates on the dynamic principle, in which a movable diaphragm and coil system is set in motion by sound waves, generating an electrical signal. The nominal impedance is 600 Ohms, enabling standard compatibility with many audio amplifiers and mixing consoles. The sensitivity of -53 dB ±3 dB falls within the typical range for dynamic microphones and ensures sufficient signal capture at moderate sound levels. The frequency range of 120 Hz to 18,000 Hz covers the entire audible range for human speech and vocals, with the lower limit sufficient for deep bass and speech frequencies, and the upper limit ensuring clear, detailed highs.

Compatibility and Accessories
The microphone is equipped with an unbalanced 3.5 mm jack plug, compatible with most standard audio inputs. The included 4-meter cable allows flexible positioning.

Mounting and Installation
Installation is achieved by directly connecting the jack plug to an appropriate input on a mixing console, amplifier, or recorder. No additional mounting or installation measures are required. The microphone is held in hand and can be positioned at various angles depending on the application.

Operational Advantages
The combination of feedback-reduced cardioid polar pattern, integrated wind and pop shield, and noiseless switch ensures reliable and high-quality signal transmission. The compact design and low weight of approximately 300 g enable fatigue-free use. The 4-meter cable provides sufficient freedom of movement without requiring additional extensions. Batteries are not included in the delivery scope.
