VT DUPLEX

The VT DUPLEX is the all-rounder of the VT DUPLEX SERIES and transmits the complete frequency range of human hearing with 20Hz to 20kHz. The omnidirectional characteristic is particularly well suited to reliably reproducing the user's voice in any situation. The VT DUPLEX also benefits from an RF-protected microphone capsule, which prevents interference from RF signals.

The VT DUPLEX has many tried and tested design features. The interchangeable headband holder is available in two sizes and is therefore equally suitable for adults and children. It is comfortable to wear and can be optimally adjusted to the wearer's build. The shape of the ear hooks has been carefully developed. They surround the ear and ensure a high level of comfort. The material used also minimises any background noise, such as that which can occur when wearing ear rings. The microphone boom can be attached on either the left or right side.

This excellent sound combined with a firm hold and unique wearing comfort makes it the first choice for stage, broadcast, presentation and speaker applications. The cable is detachable and can be supplied with the appropriate plugs for standard wireless systems.
