I need a very simple solution here. I have a Macbook Pro 13". I also do a radio show on Blog Talk Radio once per week. I'm about 80 shows in and have some offers to start doing some remote broadcasts. I need a very simple solution that I can plug 4 - 3.5 or 1/4" microphone jacks into and 4 - 3.5 or 1/4" headphone jacks into. I don't need some extravagant audio mixer as this will be strictly for talk and no instruments. Any non extravagant suggestions as i want to keep this as easy as possible and somewhat portable. I'm willing to pay up to $1,000.
