Q: 1. Does this work with g2 and g3 ew100 ? Do the mics fit in the charger?

A: The Sennheiser 4-Bay Network Charger for SL Bodypack DW and SL Handheld DW (US Version), B&H # SECHG4NUS, is a network-enabled charger featuring four individual charging bays. These can either be used for the SL Bodypack DW or the SL Handheld DW. Each bay is combined with 4 LEDs to indicate the corresponding battery status of the mobile device. It is not compatible with the Sennheiser G2 or G3 EW100 products.

Q: 2. Does this work with the Sennheiser Evolution Wireless Digital EW-D 835?

A: No, the Sennheiser SpeechLine Digital Wireless SL Bodypack DW-4-US Wireless Transmitter is not compatible for use with the Sennheiser EW-D EM Digital Wireless Receiver that is included with the Sennheiser EW-D 835-S SET Digital Wireless Handheld Microphone System. The SpeechLine Transmitter is compatible with SpeechLine series receivers such as the Sennheiser SpeechLine Digital Wireless SL Rack Receiver DW-4-US (B&H # SESLRR).

Q: 3. Is this compatible with Sennheiser AVX system?

A: Yes

Q: 4. How to reduce feedback

A: Proper placement is crucial. You want to ensure you are close enough to your source --in this case, the mouth of your presenter-- to achieve adequate gain with minimal ambience, yet far enough away as to not to pick up every breath between phrases. Once you've found your sweet spot, implement a few bands of parametric eq to catch the first frequencies that begin to propagate. Parametric eq's are easy to come by on most digital consoles but if you are working with analog gear, inserting a graphic eq at the end of your channel --after compression and before any channel groups or mix busses you may be routing through-- should also allow you to notch out the first few problematic frequencies and achieve adequate gain without carving away too much of the tone and timbre of your presenter's voice.

Q: 5. How to avoid echo & feed back

A: Stay clear of the speakers. Perform sound checks to obtain the proper level on the speakers. Maybe use one of these: dbx AFS2 Dual-Channel Advanced Feedback Suppression Processor B&H # DBAFS2
