| Microphone | |
| Microphone type The characteristics of the microphone bulit into the device in terms of the reception of signals from all or just one direction, i.e. omnidirectional (better for concerts and the like vs unidirectional, more suitable for voice recording. | Lavalier microphone |
| Wireless range | 20 m |
| Receiver | |
| Receiver type Describes type of receiver which is a device for picking up an external signal. | Stationary receiver |
| Features | |
| Radio Frequency (RF) range | 2.4 - 2483 MHz |
| Microphone frequency response | 100 - 8000 Hz |
| Total Harmonic Distortion (THD) Total harmonic distortion is a measure of non-linear harmonic distortion and is given in %. Non-linear harmonic distortions are signals which were not present in the original before the signal was converted by the headphones. These unwanted signals are caused by the diaphragm, whose movements do not precisely move in time with the electric signals that cause it to move. Unfortunately, this is a feature of all electroacoustic transducers. Although it cannot be completely eliminated, suitable steps can be taken to minimise it. However, the user is not interested in why this distortion takes place but in how great the level of distortion must be for it to become perceptible. According to the findings of several research projects, a total harmonic distortion of 1% in the frequency range of 100 to 2000 Hz is imperceptible. Below 100 Hz, the perceptibility threshold lies at 10%. | 0.5% |
| Signal-to-Noise Ratio (SNR) This is the ratio of signal intensity to noise intensity. | 59 dB |
