Who makes this product? What is the brand name?

Manufacturer seems Shenzhen RHM Electrical Appliance Company Limited in Guangdong, China - Model RM-K666 - branded by several companies of which SoundBeast is one (http://www.soundbeast.rocks/contact-us.html). I have one and like it - seems well built. I got it for presentations where I could input computer AV on one channel and use the mike on an another channel.

Will/Can it connect to a tv with Google Chromcast?

You can connect to a TV through fire stick

Does the audio effects on this unit include "echo"?

I guess you could call it echo- its more like a reverberation.

Does the system support more than 2 microphones. I plan to buy more microphones. Do you sell seperately?

Hi there, we are sorry to let you know that the system only support to connect to 2 microphone that we provided.
