Q: 1. Does Sennheiser offer a wireless solution that offers dual recording, so that two mics can be used simultaneously?

A: The only dual channel system Sennheiser makes that is similar to the EW 500 FILM G4 Camera Mount Wireless Combo System would be the Sennheiser EK 6042 Dual-Channel Slot-Mount Wireless Receiver (B&H # SEEK6042)

Q: 2. How does this compare to the Sony UWPD16/14 Wireless Microphone System?

A: They are both very popular systems and offer excellent quality for professional applications and commercial applications.

Q: 3. What should to be the frequency for Europe? Germany and Spain for Example?

A: These devices are only guaranteed as legal for use in the United States. Laws and regulations regarding wireless devices vary widely from country to country, and in some cases they may change frequently. For this reason we cannot provide a definitive statement on the laws of other countries. All of the wireless devices sold by B&H are legal for use within the United States, but customers travelling or residing abroad must check local regulations before attempting to use these devices.

Q: 4. does this have headphone jack on the receiver?

A: Yes, the EK500 G4 wireless receiver in this kit does have a headphone output. It is easier to see in this image, from Sennheiser's manual: http://www.sennheiser-sites.com/responsive-manuals/ewG4/500P/EN/ew_500P_G4_EN/images/EK_500_Lautst%C3%A4rke-Phones.png

Q: 5. Will the plug-on wireless transmitter attach properly to a side-exit XLR boom pole (particularly K-Tek Avalon), or will it not attach firmly enough, please? Would it be necessary to buy something like a K-Tek KlassicPro upgraded to their KPTA plug-on TX adapter? Is there another brand/model of boom pole that would suit the Sennheiser plug-on TX?

A: The SKP 100 G4 Plug-On Transmitter within the Sennheiser EW 100 ENG G4 Camera-Mount Wireless Combo Microphone System may not attach firmly to a side-exit XLR connection on a boompole. The transmitter features a fastening collar to tighten however it is uncertain whether this is sufficient to prevent the connection from loosening. The KPTA Sidekick Plug-On may help in that it keeps the transmitter in a more ideal orientation.

Q: 6. What frequency should I use?

A: Without knowing exactly where you will be using this system, it is impossible to make a firm recommendation. That being said, this system has a very wide freq band and features auto scan for the best possible clear freq to use. It should work pretty much every time. Just make sure you scan before you are ready to shoot, then sync it with your transmitter and you should be good to go.

Q: 7. why two transmitters if you can only use one at a time ?

A: The Sennheiser EW 500 FILM G4 Camera-Mount Wireless Combo Microphone System gives you the option of either using the Sennheiser SK 500 G4 Wireless Bodypack Transmitter and Sennheiser MKE 2 Gold Series Subminiature Omnidirectional Lavalier Microphone, or using the Sennheiser SKP 500 G4 Pro Wireless Plug-On Transmitter, which can be used with either dynamic mics or condenser mics that require phantom power - any microphone with XLR output, such as a handheld mic or shotgun style mic. The SKP 500 G4 can also be used to send audio from a mixer's XLR output to the receiver. Since the Sennheiser EK 500 G4 Pro Wireless Camera-Mount Receiver has a single channel, only one transmitter can be used at a time.

Q: 8. The mic included says MKE-2, but is this to gold version?

A: The microphone included with the Sennheiser EW 500 FILM G4 Camera-Mount Wireless Combo Microphone System is the Sennheiser MKE 2 Gold Series Subminiature Omnidirectional Lavalier Microphone. If you look at the "In the Box" section on the right side of the page, you will see it listed.

Q: 9. Are there any compatible antennas for this to extend the range?

A: No. The Sennheiser EW 500 BOOM G4 Camera-Mount Wireless Plug-On Microphone System includes the bodypack-style EK 500 G4 Pro Wireless Camera-Mount Receiver, which has an integrated/molded antenna, the receiver cannot be used with an external antenna. If you swap the EK 500 receiver and use the Sennheiser EM 300-500 G4 Wireless Receiver (such as B&H # SEEM3005MGAP for AW+: 470 to 558 MHz frequency band), you will be able to use remote mount antennas or half-wave antennas for extended range. However, the EM 300-500 requires AC power and is not camera-mountable, so that could be a drawback if you need to have a portable, battery-powered system.

Q: 10. Will this make interference if I have the Sennheiser ew IEM G4 Wireless Monitor System (A1: 470 to 516 MHz) next to me?

A: No, the Sennheiser EW 500 BOOM G4 Camera-Mount Wireless Plug-On Microphone System will not interfere with the Sennheiser ew IEM G4 Wireless Monitor System (A1: 470 to 516 MHz). Each system's transmitter and receiver will pair to a different frequency to use for transmitting audio, so even though the bands overlap, there should be no problems with interference between the two systems.
