General Description
The Set 830-TV is an infra-red stereo TV assistive listening system. The set enables assistive listening anywhere in the room without the need for cables and without disturbing others. Directly connectable to a TV, hi-fi system or radio, the Set 830 guarantees outstanding sound quality, which, for example, thanks to treble emphasis, can be customised to the listener’s hearing.
What’s more, the receiver is extremely lightweight and, with its perfect-fitting ear cushions, offers maximum comfort when worn. Ergonomic controls and visual signals for the individual control processes mean that operation of the Set 830-TV couldn’t be easier.

Glossary
| Charging time |
| The time required to recharge a Sennheiser accupack. After recharging, automatic chargers will automatically switch to trickle charging. |
| Frequency response |
| The frequency response of a microphone is given within the limits defined by the manufacturer. In studio condenser microphones it is generally within the range of between 20 Hz and 20 kHz. |
| Modulation |
| The process in which one wave is varied by some parameter of another wave, for example, an RF carrier frequency that is modulated by an audio signal. Types of modulation include amplitude modulation, frequency modulation, pulse code modulation and pulse width modulation. |
| Operating time (receiver) |
| Indicates the receiver’s operating time with a new, fully charged battery or accupack. |
| Range |
| See RF wireless headphones, transmission loss. |
| Sound pressure level (SPL) |
| Due to the impractical numerical values, the sound pressure is usually given as the logarithmic value of the sound pressure level according to the equation: dB SPL = 20 x log (po / 0.00002 Pa). The abbreviation SPL (sound pressure level) is added in order to make a clear distinction from other uses of dB. The reference sound pressure, which is at the same time the threshold of hearing, is then 0 dB SPL. The threshold of pain is 140 dB SPL. A difference in the sound pressure level of 1 dB is just about perceptible, while a doubling of the sound pressure corresponds to 6 dB and a doubling of the volume corresponds to a rise of 10 dB. |
| 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%. |
| XLR connector |
| Most common form of connector in audio studio technology. |
