IwannaRock2, it's not about jacks, it's about type of signal that they carry.
There's two types of signal you should know about (in current context): balanced and unbalanced.
Cable for unbalanced signal has two wires: hot and ground. Connectors for unbalanced signal cane be 1/4" mono jack and RCA.
Cable for balanced signal has three wires: hot, cold (basically inverted hot) and ground. Connectors for balanced signal can be XLR and 1/4" stereo jack (also called TRS – tip, ring, sleeve).
The main difference from user perspective is that balanced signal can "travel" further distance and pickup less noice than unbalanced.
Studio hardware usually can accept both balanced and unbalanced signals through 1/4" input – it would figure out type of signal by type of jack (mono/stereo). And there's description for your outputs (page 7):
#2. 8 TRS jack sockets for balanced outputs 3-10. – will accept either balanced or unbalanced jacks.
#3. TRS jack sockets for balanced outputs main monitor mix. – will accept either balanced or unbalanced jacks.
With that said, you can use 1/4" stereo to 1/4" stereo cable or you can use XLR to 1/4" stereo jack cable. But, 1/4" mono cable should also work.
