using lectrosonics smb transmitter with a sennheiser ew100 g2 receiver

Many Lectrosonics transmitters CAN do different modes to be compatible with other receivers. The US models, for instance, can be put into 200 Series mode (older analog Lectrosonics), IFB, Sennheiser 3000/5000 (HiDyn Plus) and older Shure (pre-UHF-R). We have heard reports that for G2/G3 compatibility, users find that Mode 6 (Shure UHF) works well.

However, the EU units the the SMb you asked about only have two modes: 400 Series (Hybrid) Lectrosonics, and IFB. The reason for this is that each different modulation scheme requires a different certification and thus becomes prohibitively expensive. Thus, the SMb has no good way to "talk" to an EW 100 Series receiver.

To work with a Sennheiser ew receiver the Lectro will have to transmit Sennheiser HDX noise reduction - if it can't do this it's not compatible, so don't do it.

Consider the excellent possibility that a "very good deal" on just a transmitter (vs. the whole TX/RX kit) has a strong aroma of a piece of stolen gear. In your country are there any lists of stolen gear serial numbers? I would consider contacting the official dealer(s) to see who they sold the serial number to.

Yes - very much so.

9 times out of 10 a s/h transmitter, sold on it's own, is likely to be stolen.

Trew Audio's reputation is stellar.
Just the same, the combo won't work.

Re: using lectrosonics smb transmitter with a sennheiser ew100 g2 receiver

hi everybody, sorry to exhume this thread, but I don't understand all these clarifications on the about the oddity of buying a single transmitter or receivers considering that eBay is full of it and even trew audio has some.

Buying something like that from an official (and/or reputable) vendor is NOT AT ALL the same thing as buying it on Ebay. Especially if the seller cannot (or will not) reveal the serial number so that you can check it against stolen goods. Why does that seem unusual to you?

Mixing Lectro with G3 is the less than great idea.

But buying individual TX/RX Lectros from eBay to match up later, sure, why not? I do it all the time, you don't need to always buy them in pairs.

Re: using lectrosonics smb transmitter with a sennheiser ew100 g2 receiver

wireless audio isn’t the area you want to be fooling around with. If your work justifies the cost of Letro then buy a new kit. What you’re are trying to do runs counter of the point of owning a Letro. It’s akin to buying an old luxury car with a million miles so you have the bragging rights to owning a high end brand.

Re: using lectrosonics smb transmitter with a sennheiser ew100 g2 receiver

The key factors in mix and match success relate to things like bandwidth, companding ratio, noise reduction, pilot tones, and now programming (as often units program each other via RF or IR)

In practice, you can try them and see what they sound like. if you like it, you use them. However, often the results are just not pleasant to listen to, or there is distortion on the speech peaks, or excessive noise, or most common - no sound at all!

Some combinations, as I think I've mentioned before, work quite well. Sennheiser microphones with Trantec receivers work rather nicely - with a hint of compression, but the other way around the commanding ratio works against you, and live, feedback is never far away, and once it goes, it really goes. Shure and Sennheiser often suffer from intermod interference that is only OK with a very wide gap between their frequencies, and trying Sennheiser with some Chinese kit failed miserably - chronic distortion.

In all seriousness, if you buy separate bits, buy from the same manufacturer, and generation/model ranges.
