3. Selecció de freqüència: Once the scan is complete, select a free frequency from the options displayed on the receiver. Alternatively, you can manually set a specific frequency if desired.
4. Sincronització: With a frequency selected on the receiver, press the 'Sync' button on the receiver unit. Then, hold the microphone module close to the receiver's infrared (IR) port. The receiver will transmit the selected frequency information to the microphone, establishing a synchronized connection.

En funcionament

• Supercardioid Pickup Pattern: The MMD 845-1 features a supercardioid pickup pattern, which is highly effective at capturing sound directly in front of the microphone while significantly rejecting sounds from the sides. This characteristic is beneficial for minimizing feedback and unwanted ambient noise, ensuring clear vocal reproduction.
• Configuració ajustable: The microphone module includes small, discreet controls that allow you to navigate a menu on the transmitter. Through this menu, you can adjust various settings, such as the microphone's sensitivity, to optimize performance for different vocalists or sound environments.
• Secure Power Button: The power on/off function is controlled by a small red button located at the back of the module. This design prevents accidental power-offs during performances or critical use.
• Interchangeable Capsules: A key feature of this system is the ability to change microphone capsules. The MMD 845-1 capsule can be easily unscrewed and replaced with other compatible Sennheiser capsules, such as cardioid or other specialized types. This allows for flexibility in sound characteristics to suit different applications or preferences.
