Q: 1. Headphone jack?

A: This is the 512P G4, yes, has a headphone jack to monitor at the receiver.

Q: 2. Can these lavalier be wirelessly connected to a soundboard?

A: Yes. The Sennheiser EW 112P G4 Camera-Mount Wireless Omni Lavalier Microphone System can be connected to a soundboard (mixer). The system comes with two receiver output cables, one with a 3.5mm connector and one with an XLR connector. You can use the cable with the XLR connector to send the output from the receiver into a mic input on the board.

Q: 3. are these still legal in the US? Here's what the FCC says about frequencies - Unlicensed wireless microphone use is permitted on the 902-928 MHz band, the 1920-1930 MHz, and on portions of the 2.4 GHz and 5 GHz bands under specified power levels and rules for operation for each of those bands.

A: These are legal in The US without a liscence. The FCC currently allows wireless microphones in the range of 470-608Mhz to opperate.

Q: 4. What is the difference from the EW 512P to the EW 100? - In other words, why is there such a price difference?

A: The ew 512P system has a wide 88 MHz bandwidth with 3520 frequencies and an adjustable RF output level of 10, 30 or 50 mW. Depending on your location, you can operate up to 32 wireless systems simultaneously. The ew 100 has a 42 MHz bandwidth with 1680 frequencies and a fixed RF output level of 30 mW. You can use up to 12 ew 100 systems at the same time depending on the environment. The ew 512P includes the MKE 2 lavalier which is a more professional mic than the ME 2-II (or ME 4) which is included with the ew 100 system. Additionally, the ew 512P has a headphone jack on the receiver but the ew 100 does not have a headphone jack. The ew 100 system also includes a plug-on transmitter (SKP 100) for use with dynamic mics and mics that do not require phantom power. If you do want to add on a similar plug-on transmitter for the ew 512 or use the ew 500 system, the SKP 500 does supply +48V phantom power.

Q: 5. It this model's frequency a good fit for recording in NYC?

A: Yes, frequency band A1 can be used in New York City. However, channels 14, 15, and 16 will be blocked for public safety deployment.

Q: 6. Does it come with a case?

A: No, it does not. We offer a nice waterproof case from SKB that already has the cut outs for the transmitter and receiver, and has some room for accessories. https://www.bhphotovideo.com/c/product/1288521-REG/skb_3i_0907_bh1_iseries_waterproof_sennheiser_ew.html

Q: 7. If I'll buy 2 receivers and 2 transmitters, what else I would need to connect it to my DSLR camera? I need to connect 2 people at the same time and I'm intending to use it together with 2 of sanken cos-11d ( i have a NIKON D800 and a Nikon D850)

A: Hi Vasile - to use two receivers on your DSLR, you'll need to split the signals so that they are routed independently to the Left & Right channels of the stereo input on your camera. This can be done using a Stereo Y-cable (e.g. Hosa Technology Stereo 3.5mm Male TRS to Two 3.5mm Female TS Y-Cable (6")). Once captured, you'll need to split the signals in post from a stereo feed into to mono channels (Channel 1 = Left, Channel 2 = Right). Alternately, it may be worthwhile to look into a portable audio recorder as the preamp will be quite an improvement over the mic input on the camera - you can send your signal from the EW Receivers into a camera mounted recorder and use a stereo output to the camera while having much more control over your audio and monitoring with much better quality.

Q: 8. I've read that the AVX series introduces a 19 ms delay. Does this system introduce any delay? I will sometimes want to run wireless and wired microphones at the same time.

A: Hi Dave - the evolution Wireless series is an analog wireless system that operates on UHF frequencies - there's no delay with respect to transmission time. However, the distance of your wired microphone capsule from your wireless lav capsule should also be taken into consideration - due to timing differences between direct audio and distant audio, you can get a phasing sound, making your audio a bit hollow or lacking body. The AVX system operates on a DECT Wireless standard, which has 19ms of delay - we generally recommend to not mix G4 and AVX wireless together for that reason.

Q: 9. Which frequency would be best for Hawaii (specifically the North Shore of Oahu)? I see some frequencies aren't allowed in Hawaii? Maybe? A specific frequency would be appreciated.

A: There is no one frequency that is best to use all of the time. Any of the bands offered will work throughout Hawaii. The reason there are three bands is so that you can use many systems in the same space and at the same time. The receiver will scan for the best available frequency within that band to use at that time. You can use up to around 8 systems in the same band, in the same space and at the same time, before you would need to worry about switching bands for your next group of systems, to avoid interference with your first group of system.

Q: 10. Can I used this mic to shoot with my gopro 6?

A: Yes you can, if you have the GoPro Pro 3.5mm Mic Adapter, BH #GO35MA. https://bhpho.to/2xKXdEv
