how to adjust the evolution wireless sennheiser
Hi everyone, I just got the evolution sennheiser wireless set and I want to ask if someone uses it and knows what are the optimal settings conserning sensitivity on the transmitter and AF out on the receiver. Any info would be very much appreciated as I am going for a long shooting on the 9th. I am planning to use a small mixer that I have, from ASDN, 2 channels if this changes something.
Thank you. Panos Bournias |
This helped me get started after I got my set.
http://link.brightcove.com/services/...bctid187745393 There is a tutorial there for the G2 (if you have the original I am not sure how similar they are if at all) |
re- adjusting the G2
Thanks Josh, this was really helpful.

After watching the tutorial, I've reduced the squelch to LOW, I guess I could get a few extra feet of range this way, but it seems like a choice between silent dropouts and loud dropout hiss. I guess it's a wash either way on this system.

I haven't watched the tutorial, but, I can tell you what I've found with the Senn G2. First, it's highly sensitive to stray RF emissions. This will REALLY limit your range. There are 2 things you can do to reduce stray RF.
1-keep the xmitter away from any known sources. Cameras(!), audio recorders, and anything digital uses oscillators that generate RF. If you can't remove RF sources, try shielding from them with something like tin foil. 2-Use the scan frequency button on the xmitter and receiver. The unit will pick a frequency with the lowest interference. |

The squelch control works on the noise in the xmitted audio. Even weak RF, generated in external sources, will effectively jam signal reception, regardless of the squelch setting, if the external RF frequency is close to the frequency of the transmitter, or a harmonic of, the receive frequency.

Squelch seems to be effective in cutting interference to a minimum in my experience with G2.

I think we're saying two different things. Yes, I agree with you completely. Neverttheless, squelch is an internal electronic process that has no effect on the strength of external RF sources. If you have an external RF source at a frequency close to the xmit/receive freq, it will JAM the signal and you'll receive absolutely nothing. Same effect as turning the squelch up all the way, but, different physics going on. It's possible that the lowest setting of squelch, doesn't turn squelch off, just reduces it to a lower level. Any external RF noise is enough to trigger even the lowest squelch setting on the G2. The G2 also has a circuit that looks for a carrier wave frequency embedded in the xmit signal. If it doesn't "hear" the carrier, it automatically mutes the receive output. Unfortunately, an external RF noise source doesn't have the carrier wave, and if it overpowers the proper xmit signal, the receiver will mute the output. Sometimes, this can be very frustrating. |
What about sensitivity settings?
What about the sensitivity and AF out settings... What are the optimal setting for the JVC when settings are in -50db? It is not clear in this tutorial. Can someone post his settings please?

I pad the lav & hand held mic down to -30db while leaving the receiver at 0db AF OUT.
I use AUTO audio level adjust on the HD100. |
