The gooseneck modules of the DAM series GN ESP for fixed and mobile installation feature a programmable mute switch that can be set to various functions, such as On/Off, Push-To-Talk, or Push-To-Mute. Together with the clearly visible LED ring for the MIC on/off indication, the GN ESP modules can be perfectly used as a small discussion system. The GN ESP gooseneck modules are available in three different lengths: 15 cm, 30 cm, and 50 cm. The design of the electronic circuit provides high immunity against high-frequency interference. The gooseneck module is compatible with all capsules of the DAM series, CK31, CK32, CK33, CK47, and CK80, through very reliable contacts.
