For sale is a Tascam US-122MKII USB sound card with microphone preamp, and a Dayton EMM-6 calibrated measurement microphone.
This is a great setup to get started with Room EQ Wizard. Both the mic and the Tascam come with all accessories and software. I'd prefer to sell them together, but feel free to make an offer for one or the other.
I accept Paypal or Chase Quickpay, and will only ship to the continental US (included in listed price). PM for details and interest.
