What else you need to use it
Worked out from FIFINE’s own specifications and box contents for this model. The setup builder checks the same parts against your computer and the rest of your gear.
Check first
- For USB: a USB cable that fits your computer. The box contents are not confirmed for this model, so check which cable comes with it.
- A microphone stand or boom arm. The box contents are not confirmed for this model, so check whether a stand comes with it.
Optional
- For XLR: an audio interface or mixer with an XLR microphone input. A computer has no XLR input. The interface’s preamp raises the microphone’s signal and sends it to the computer over USB. Compare audio interfaces
- For XLR: an XLR cable. None comes in the box.
- Wired headphones with a 3.5 mm plug. Its headphone socket lets you hear yourself straight from the microphone, before the computer adds delay. Headphone test
When this model makes sense
- Record one voice over USB now, or through an XLR interface later; get the placement right before adding effects.
- Use its headphone socket to hear yourself while you set distance and gain.
- Use it with an XLR cable and an interface that has enough gain. Its USB voice effects don’t apply on XLR.
The USB versus XLR guide weighs it against the other ways to fill the same role.

Check these conditions first
Not yet confirmed from FIFINE’s documents: operating systems, included parts, dimensions, needs 48 V phantom power. The builder treats them as unknown, never as a yes.
For a microphone, set your distance and input gain before adding any processing. Speak as loudly as you will on stream, listen back to a recording and leave some headroom. Judge a USB/XLR microphone in the mode you will use: its USB voice processing does not carry over to XLR.
What is included, and what may be missing
The maker doesn’t publish a full list of what comes in the box. Check the box contents for your region before you count on a cable, stand, power supply or adapter being included.
Both cable ends and the data rating matter more than the plug shape: streaming cables and ports explains how to match them.

The diagram shows a simple USB setup. Find where the FIFINE AmpliTank K688 goes, then follow each input back to what feeds it and each output on to where it goes. HDMI and XLR gear needs a capture card or audio interface between it and your computer; it doesn’t plug straight in the way this USB example does.
The setup builder turns this into a connection list for your own computer and gear, and the pre-stream checklist covers the rehearsal once it is wired.
