My question would be' why do you want to connect up to something else anyway'?
It's a practice amp and from the description, quite small and low in features. If you want to gig it will probably not be large enough anyway so if there is a PA, just DI straight into that. You'll hear yourself in the monitors.
Otherwise you may need to invest in something, either more powerful or if you want to stay small, with more features like a 'Line Out'.
What is the practice amp you have?
