[AG-TECH] help on ATI MM100 & ATI BI100

[lujian]

Hi,
	I ordered a ATI MatchMaker100(http://www.atiguys.com/mm100.html) , but the seller gave me a ATI BI100 Stereo Bi-directional (IHF to PRO Interface Amplifiers) (http://atiguys.com/bi100.html),
	I have a poor knowledge on Audio tech. Can anyone tell me the difference between MM100 and BI100? 
	Thank you!
