DPA 4066 / 4088 / 4466 / 4488

DPA 4066, 4088, 4466 and 4488 CORE+ Headset microphones

The DPA 4066, 4088, 4466 and 4488 are miniature headset microphones featuring CORE+ technology. These models are used for speech, theatre, broadcast and live applications where stable positioning and consistent sound quality are required. The lightweight headset construction positions the capsule close to the mouth, maintaining a constant distance to the sound source.

• 4066 CORE+ Miniature Headset Microphone: The 4066 is a subminiature omnidirectional headset microphone designed for speech and presentation. It provides natural and transparent sound reproduction with a frequency range of 20 Hz to 20 kHz and a maximum SPL of 144 dB. Available in black, beige and cocoa.
• 4088 CORE+ Miniature Headset Microphone: The 4088 is a directional headset microphone with a cardioid pickup pattern. It provides increased isolation from surrounding sound and supports a maximum SPL of 146 dB. Available in black, beige and cocoa.
• 4466 CORE+ Miniature Headset Microphone: The 4466 uses the same omnidirectional capsule principle as the 4066 but features a reinforced headset design. The frequency range is 20 Hz to 20 kHz and maximum SPL is 144 dB. Available in black, beige and cocoa.
• 4488 CORE+ Miniature Headset Microphone: The 4488 is the directional version of the 4466 and is designed for higher SPL environments. The cardioid capsule provides increased isolation and supports a maximum SPL of 146 dB. Available in black, beige and cocoa.
