Yes, all MG and MGP (except the MG24/14fx and MG32/14fx) mixers are rack mountable:
1. MG-82cx and MG-102c mixers will need the optional RK-MG102 kit.
2. MG-124cx and MG124c will need the optional RK-MG124
3. MGP, MG-166 and MG-206 come with built in rack ears. (no additional purchase necessary)
Do you need an additional help?
