CONSUMER ALERT
Most users do not need a license to operate this wireless microphone system. Nevertheless, operating this microphone system without a license is subject to certain restrictions: the system may not cause harmful interference; it must operate at a low power level (not in excess of 50 milliwatts); and it has no protection from interference received from any other device. Purchasers should also be aware that the FCC is currently evaluating use of wireless microphone systems, and these rules are subject to change. For more information, call the FCC at 1-888-CALL-FCC (TTY: 1-888-TELL-FCC) or visit the FCC’s wireless microphone website at

Glossary
| Switching bandwidth |
| The frequency band in which frequencies can be switched directly. |
| Peak deviation |
| Maximum permissible deviation for FM. |
| Compander |
| Also known as noise reduction system. A system which improves the signal-to-noise ratio by compressing the dynamics on the transmitter side using a compressor, and subsequently restores the normal dynamics on the receiver side using an expander. |
| Frequency response (microphone) |
| 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. |
| In compliance with |
| Gives the guidelines and requirements which have to be met before a unit can be put onto the market. Such guidelines are published by e.g. standards committees, telecommunications authorities etc. |
| Audio output level (balanced) |
| Logarithmic value of the audio output voltage based on a standard reference value. A balanced circuit or connection uses separate signal lines for sending a signal, returning the signal and ground (3-pole connection). |
| RF output power |
| Output power measured at the antenna socket. |
| Operating time |
| States how long a unit can be continuously used with one set of batteries / rechargeable accupack. |
| Input voltage range |
| Indicates the voltage range of the input signal within which a unit will work properly, i.e. as specified in its technical data. |
| AF sensitivity |
| Specification used for judging the quality of acoustic transducers. A given sound pressure level will generate a certain voltage and vice versa. |
| 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.
|
| Pick-up pattern |
| Also known as polar pattern, directivity. According to their acoustic design, microphones differ in their sensitivity towards sound from different directions. Pressure microphones have a sensitivity that is largely independent of direction (omni-directional pick-up pattern). Pressure gradient microphones have the pick-up patterns wide cardioid, cardioid, super-cardioid or figure-of-eight. Interference microphones can be used to achieve a further concentration of the pick-up pattern (lobar pick-up pattern). As a special case, dummy head microphones achieve the pick-up pattern of the human ear/head (dummy head stereo). |
