Split a balanced jack to two unbalanced jacks

Hi
I will soon get a Mackie 802 VLZ4 mixer.
It has an AUX output via one jack "bal/unbal".
I wish to split/double that aux signal into two mono jacks on a recording device.

My question is:
Can I use a regular Y adapter/insert cable (stereo jack to two mono jacks) to split the balanced aux output into two unbalanced jacks?
Is it safe to do it like that, since it's a balanced signal?

An "insert" cable will connect the tip of the TRS plug to the tip of one TS plug, and the ring to the tip of the other. Not really what you want in this situation.

The "BAL/UNBAL" output is also likely only impedance balanced, which means there is no signal on the ring, just a resistor to ground. A simple MONO Y-cord (all TS plugs) will do what you want. Or even a TRS Y-cord (like you would use for splitting a headphone feed) would work, although it's likely more expensive.

Ok thanks.

Sounds like I could then lift the ring wire and solder it to the tip wire, in the TRS end of the insert cable, right?

Would it not add signal loss or alter the tone to split a signal like this?

Also, what do you mean by "a simple mono Y-cord"?
I have trouble finding it

No. It is dodgy to use a TRS connector when connecting to or from a mono signal, especially if one end is balanced and the other end is unbalanced. You run the very real risk of having your signal disappear under mysterious circumstances.

Not unless the gear was broken.
