These AKG C 98 Mics ofern come with testing kit like the Lexicon MC-12.
The are well made both feed into a mini jack with wire about 2.3m in lenght meaning with the jack centred the mics can be around 4.5m apart. They come with mini mic stands which are again well made and not as plastic as they look.
AKG make brilliant micphones and I used these with a digital 4 track to get a good room sound. Not used in a while, but to good to throw.
These are Condensor mics I understandd but wired up together as mono form a Olympus Digital Conference kit.
