For the Sennheiser EW Series equipment there is a proprietary rechargeable battery system that is designed specifically for these products to ensure the best operation time possible when using rechargeable batteries.
The rechargeable battery system consists of the following components:
- BA2015G2 = (rechargeable battery pack)
- L2015 = (charger for two units)
- LA2 = (charging slot-in adapter for a G3 or 2000 series handheld microphone)
- NT1-120 = (power supply for a single L2015 charger)
- NT3-1-US = (power supply for up to three (3) L2015 chargers daisy chained together)
NOTE: The BA2015G2 battery pack can be placed directly into the L2015 charger for charging. When using the BA2015G2 battery pack in a SK or EK device the whole body pack can slot directly into the charger to charge the battery packs allowing charging in the device.
When a handheld microphone is used in conjunction with the LA2 adapter the handheld microphone and LA2 adapter can slot directly into the charger to charge the battery pack without having to remove the battery pack from the handheld microphone.
There are two main settings that will typically affect sound quality:
This is how sensitive the microphone pick up is and this is adjusted on the handheld microphone, bodypack or SKP transmitter itself. Typically for general speaking the sensitivity should be set around -15 to -18 dB. You will need to adjust this depending on the exact application. Closer to 0 dB is more sensitive and further away from 0 dB is less sensitive. If the microphone is too sensitive the input will overload the microphone and the AF level will peak and the audio will be clipped. The sensitivity should be set so the AF PEAK indicator only lights up during the loudest passages.
This is how strong the final signal exits the receiver into the sound board/PA system/recorder etc. The "AF OUT" setting is found only in the receiver's menu settings. Typically this will be set around 0 dB or +6 dB if you connecting to a line level input on the sound board/speakers/etc. If you are trying to connect to a device which expects a mic level input, you will typically need to drop this AF output down to -24 dB or -30 dB.
NOTE: If the AF Output is too high it may overload the input (peak) on connected device and may create undesirable noise (distortion, rumbling, etc).
The Evolution Wireless (EW) products are built according to their frequency range when manufactured. It is not possible to re-tune or switch the frequency without switching out the RF boards which is often more expensive than purchasing new equipment.
In June 2010 the FCC instituted regulations that made it illegal to operate wireless microphones within the 700 MHz frequency range in the United States.
With the transition to digital television TV broadcasters vacated a large section of the UHF spectrum (from 698 to 806 MHz) so the FCC auctioned the 700 MHz band to the highest bidders (including AT&T and Qualcomm) to facilitate the development of wireless broadband Internet service throughout the United States. In addition, the FCC has reserved select frequencies in the 700 MHz band for emergency and national security purposes.
NOTE: The FCC is the Government agency tasked to regulate interstate communications by radio, television, wire, satellite, and cable in all 50 states, the District of Columbia and U.S. territories. The FCC sets the guidelines and regulations for all broadcast equipment (including wireless microphones).
EW is the acronym for Evolution Wireless.
