Mixer to send sound from keyboard and computer.

[NeedyJay]

Hello everyone,
(As some of you may remember) I own a pair of JBL 305P MKII monitors. What I want to do is to be able to connect my computer and my keyboard to a mixer and then send the combined sounds into my speakers. Now, ive done my research so the reason Im making this thread is to make some clarifications. First of all im thinking of buying the budget Depusheng DX400/Moukey MAMX-1 (are they undercover bombs?) . The question is what cables I need to buy/connect in order to achieve that. On some Ive seen they only take in TRS jacks while on others it doesnt matter.
Since both of the mixers have only 1 output im most likely going to need a Y splitter. Also is a Y splitter going to be needed for my computer because it has stereo output?
Thanks.
(I hope this is the correct forum)

For what reason?

For what reason?

to convert unbalanced, high-impedance signals into balanced, low-impedance signals, allowing long cable runs without hum, buzz, or high-frequency loss

Oh yeah, I dont really care about the lenght of the cables since they are going to be 3 meters max.
