I am selling my Theta CB IV SSP. The unit is about 2 years old and it is in excellent condition; this is an orginal CB IV. I have had this in my dedicated HT for the entire time. When I purchased the unit, I had it configured for 12 output channels: 1 XTreme D2 card and 2 Premium cards. Earlier this year I upgraded to a D3 card. I still have the XTreme D2 card which I will include with this unit. The cards are easy to replace, so you can have a D3/D2/Premium configuration with a spare Premium card. I have the original box and remote control.
