Related Questions and Answers

Q: 1. Hello! This package have two receivers only; Can I use more receivers for same transmitter over same frequency?

A: Yes, you can add more recievers, which would all receive the same mix. The appropriate reciever is the Sennheiser EK IEM G4 Stereo Bodypack Receiver with IE 4 Earphones (A: 516 to 558 MHz), BH #SEEKIEMG4A.

Q: 2. can you add more receivers than two?

A: Yes you can. When adding additional receivers, make sure they are all on the same band and then just tune all receivers to the same frequency and it will work perfectly.

Q: 3. I currently own the Sennheiser XSW-D lav set and need to upgrade to a system that will allow two mics simultaneously. Will this receiver allow more than one mic at a time and if so will my existing transmitter work with this receiver?

A: No, the Sennheiser EK 100 G4 Camera-Mount Wireless Receiver included with the Sennheiser EW 122P G4 Camera-Mount Wireless Cardioid Lavalier Microphone System is single-channel and can only be used with one transmitter. Sennheiser does offer any camera-mountable receivers or other EW Series wireless receivers with two channels. You will need to get a second receiver in order to use two transmitters at the same time. If you need to use two mics and have a camera with a single mic input like a DSLR or mirrorless camera, you can use a passive mini mixer such as the Kopul CMX-1-V2 Two-Channel Mini Mixer with Shoe Bracket (B&H # KOCMX1V2) or the Kopul CMCS-1 Passive 3.5mm Microphone Combiner/Splitter (B&H # KOCMCS1) to connect the output from each receiver and then send one signal with the audio from both mics into the camera.

Q: 4. Can I use this device to transmit Zoom meetings? So my presenters can listen to the questions in ear?

A: Yes you csn send the audio from a computer into an audio interface or mixer and out to the Sennheiser ew IEM G4-Twin Wireless Monitor System Kit.

Q: 5. Will these potentially interfere with lavaliers that have already been paired on a film set? I'd like to use these as IFBs.

A: Yes, the Sennheiser ew IEM G4-Twin Wireless Monitor System Kit (A1: 470 to 516 MHz) can be used on a film set where wireless microphones are already being used. As long as the 470 to 516 MHz frequency band will work in your area and does not already have a large number of wireless mics operating on the same band, there should not be any problems. The IEM G4 system offers 1,680 receiving frequencies,

Q: 6. Is the xlr out line level?

A: The XLR out is a balanced MIC level output, while the 1/4-inch out is an unbalanced LINE level signal.

Q: 7. Is there a way to assign left channel to one receiver and right channel to another, either through the transmitter or the receiver configuration settings?

A: Unfortunately not , channels are not assignable.

Q: 8. Can the transmitter be battery powered? Perhaps via an Audioroot BDS?

A: While I haven't experimented with it, technically you should be able to. It's a 12vdc input. So as long as you have the right cable and an adequate battery, I don't see why not.

Q: 9. Should I get a different frequency if want to get two?

A: That is not necessary. The bodypack transmitter provides up to 8 hours of operation on two AA batteries, with a fixed 30mW RF power output and a transmission range up to 330'. Up to 12 wireless mics can operate simultaneously in the same space, with the receivers linked together for fast, multi-channel frequency setup. Fast Multi-Channel Setup for Expanded System To simplify and speed up your workflow, two RJ10 data networking ports allow you to daisy-chain up to 12 receivers and quickly perform a frequency setup for the entire multi-channel system via the Easy Setup function. If you assign the frequencies manually, you can expand the setup to accommodate a maximum of 20 receivers. An RJ10 cable is included.

Q: 10. Can the speaker feel the mic being switched to mute or is it a soft touch switch?

A: The physical mute button is located on the top edge of the transmitter ad can eaily be felt by the user.
