How does a noise-canceling microphone work?

A noise-canceling microphone filters out unwanted background noise. It does so by differentiating between sounds that come from nearby sources, such as from the mouth, and those that are more distant. The distant sounds are then eliminated, thus providing crystal-clear communications. It is important that the noise-canceling microphone is positioned close to the mouth (approximately 2 cm/less than 1 inch).

What is Quick Disconnect (QD)?

Easy-to-use and robust plug that connects to corded Jabra headsets and amplifiers. Lets you momentarily hold your call, disconnect your headset, and walk away from your desk. To resume the call, simply reconnect your headset.

What is acoustic shock?

Acoustic shock is a sudden, shrill sound from the telephone network that can damage your hearing. That is why Jabra contact center headsets cut off sounds at 118 dB. Moreover, thanks to digital technology, the GN8210 amplifier provides you with even better acoustic shock protection, instantly cutting off any overly-loud sound before it reaches your headset.

What is PeakStop™?

PeakStop™ technology protects against sudden loud sound spikes. Many acoustic experts define acoustic shock as being exposed to a sound of over 135 dB SPL, but even lower sounds can damage the ears. Therefore, Jabra contact center headsets cut off sounds at 118 dB SPL (RMS)*.

What does wideband and Hi-Fi bandwidth mean?

Wideband refers to the frequency range supported by the headset when transmitting and receiving sound. Regular landline telephony is limited to 300 - 3,400 Hz. Wideband is defined as 150 - 6,800 Hz. Hi-Fi bandwidth has a frequency response that is even better than wideband. Jabra Hi-Fi headsets have receivers with a frequency response of 80 - 15,000 Hz.

What is IP telephony?

IP telephony is a technology for transmitting ordinary telephone calls over private IP networks and the Internet instead of using standard public switched telephone networks.

What Is USB?

USB, Universal Serial Bus, has become a standard connection port for many devices such as keyboards, mice, joysticks, digital cameras and headset solutions. Users without a lot of technical knowledge can easily connect a USB device to their computer.

What is DECT?

DECT is a radio technology ideal for voice, data, and networking applications with range requirements of up to a few hundred meters. Because the DECT standard delivers high speech quality and security with very low risk of radio interference, it is used for most cordless desk telephones.

What is IntelliTone™?

IntelliTone™ reduces noise on incoming calls and it provides automatic limitation of the time-weighted average noise exposure during a workday. IntelliTone™ is made possible thanks to DSP (Digital Signal Processing) in the GN9350.
