Verbex VT-801D Conference Delegates Microphone with Built-in Speaker is perfect companion for the VT-8000 Series Conference Central Amplifier System. 

Specifications:

• Supercardioid unidirectional condenser microphone: This means it picks up sound primarily in front of the microphone and reduces noise from the sides and back, improving speech clarity in conference settings.
• Gooseneck microphone with red speaking indication halo: The bendable gooseneck allows for flexible positioning, and the red halo light likely indicates when the microphone is active, promoting a smooth flow of discussion.
• Microphone switch with dual-color speaking status indication: This provides additional visual feedback on the microphone's status, likely with colors like red for active and green for muted.
• Powered by DC18V from the system host: The microphone receives safe power directly from the central unit.
• Dual headphone jacks (3.5mm): Allows participants to directly monitor the conference audio through headphones.
• Built-in speaker with volume control knob: Provides the option to listen to the conference audio through the microphone's speaker, with adjustable volume for personal preference.
• Automatic mute function: This could be helpful to prevent unwanted noise when not actively participating.
• Comes with a 2.1-meter 8P male cable: The microphone comes with a pre-attached cable for easy connection to the central unit.
• Hand-in-hand connection between units: Likely refers to a daisy-chain configuration where microphones can be linked together, simplifying installation.
• Country of Origin: UAE
