Help purchasing additional mics for Sennheiser ew122-p g3 set.

[SGCman]

The set I recently purchased came with:
EK 100 G3 Receiver
Sk 100 G3 Transmitter
ME 4 Cardioid Mic

I want to buy 1 handheld microphone and 1 more wireless (probably omni). I don't really know **** about audio equipment, so I want to make sure I don't screw up and buy the wrong stuff.
Can you guys point me in the right direction (direct links would be awesome) of exactly what I need to get?

Also, am I going to have to buy some kind of a mixer to plug all of this stuff into in order to record on 1 clip or is there a way to get all of the audio on one receiver that I plugin to my camera?

For a hand held, the SKM 100 hand held mic/transmitter is one option ..OTOH, the SKP 100 Plug-on transmitter would allow using any dynamic mic or mic level audio source. It does not however supply Phantom Power. If PP is needed, the SKP 2000 plug-on transmitter would be the choice. All of the above transmitter options would need to be the same frequency block as your existing system. If buying a complete second system, the same is recommended.
Lots of choices for lavs, depends on your budget and preference. In any case, an omnidirectional lav is a must. The Sennheiser ME2 mic (bundled iwith the w 112 system) is usable but not great. The cardioid ME4 lav, for all intents and purposes is pretty much useless, except in a live feedback prone situation. The Sennheiser MKE2, Sanken COS11 Sony ECM88 and DPA 4071 are top shelf IMO. Other less expensive options are the Tram TR40, Countryman B3/6, RODE, ect, ect. IMO, the most cost effective (bang for the buck) option is the Oscar SoundTech OST-801/802 or TL40, and also highly regarded.
Search this and the DVi audio forums for more info and tips for optimum performance.

Thanks for the info. I guess my biggest confusion comes from knowing what transmitter to get due to frequency.

My current Transmitter says "Freq. Range A: 516-558 MHz," so I should only purchase an item that says that same thing in its description? Does that mean that all the mics can go to 1 receiver? Or are you saying that if I buy a new mic/transmitter, I need to buy a receiver that matches its frequency?

For example, if I want to buy this:

I have to buy a 2nd receiver? Which one?

If you want to use a different type transmitter with your existing receiver, it would have to be on the same frequency block. (range A, 516-558 MHz in your case) However.. two or more transmitters CANNOT be used with a single receiver. (all tuned to the same frequency) OTOH, multiple receivers can be used with a single transmitter... for instance, sending a single mic or other audio source to multiple cameras/recorders., that is one of the reasons for having the same frequency block. (mix and match) Another advantage is using multiple channels within the same bank eliminates inter-modulation issues. For instance, one actor's transmitter on Bank-5 Channel-7; a second actor's transmitter on Bank-5 Channel-8; a third actor's transmitter Bank-5, Channel-9 and so on. All would coexist without issue.
BTW, a "System" is a 'Transmitter/Receiver' combination.

Correct.

Does that mean that all the mics can go to 1 receiver?

No. Every transmitter has to have at least one receiver matched to it's specific frequency. Receivers do not multitask; they listen to exactly one single frequency at a time. Each of your transmitters must be set to a separate frequency so they don't interfere with each other. They can all be in the same range, but not on the same exact frequency.

Or are you saying that if I buy a new mic/transmitter, I need to buy a receiver that matches its frequency?

Again, yes.

For example, if I want to buy this:

Again, yes, you have to buy a second receiver. For the mic you've linked to, a receiver that receives the Sennheiser A range.
