i have the 8gb ballistics sport ddr4 2666mhz (one stick) Ab350 motherboard that supports up to 3200mhz a ryzen 5 1600. Speccy is saying its running at a freq. of 1330, and that it is single channel.

It's correct. Speccy and CPU-Z both read the actual speed of the RAM. RAM is sold marketed at effective speed. DDR = double data rate. Information is sent on both the rising and falling edges of the clock cycle. So to get the effective speed you double the actual speed. DDR4 3200 reads as 1600 etc.

Dual channel does not factor in here.
