Unbalanced / Balanced Connection

I'm new to gearslutz and hope I'm posting this in the right forum. I'm wanting to connect a Yamaha MSR100 powered speaker output to an H4n zoom recorder.

Documentation specs:
speaker output: –10 dB (0 dB=0.775 V) / 10 kΩ / unbalanced phone
recorder input: −10 dBm _ −42 dBm / 1 kΩ / balanced xlr

Will a passive direct box give me optimal results?
Recommendations on brand?
Does the 10 kΩ output to 1 kΩ input present issues?
Thanks for any advice!

Of course it presents a problem, idealy the input impedance of a device should be at least 10 times greater than the output impedance of the device its connected to, so basically you have it backwards!, you are connecting it to an input 1/10th the impedance of the output.....

A DI box should be enough... but youll need a pre-amp unless theres one bundled in your zoom. Just get radial JDI

The Zoom has combo input jacks. Use the unbalanced 1/4" connectors.

^^^^ As Joe said

The Zoom accepts unbalanced inputs @ 480kΩ in addition to what you stated, thus it is a "combo" input.

Use 1/4" TS cable and you're done.
