Lets take a look at the software end of the UX8. First of all, just as with all Line 6 products, the interface is compatible with Monkey, which will allow you to check if your Line 6 gear is up-to-date with the latest drivers and software. In fact, this small utility not only verifies that you have the latest version of the UX8 driver, you also have the possibility of buying supplementary sound banks (more « metal » oriented for example). As for the driver itself, it's pretty standard with it's sample rate (up to 24 bits / 96 kHz) and buffer (128 samples minimum) configuration. With my setup (Intel Core 2 Duo à 2,4 GHz / 2 Go de RAM) and latency at the minimum setting, the system didn't crackle or show the slightest sign of overload or slowing down. A good point!

By using the input tabs, you can choose a level for each one: Line, mic or even instrument for the first two. You can even create stereo pairs for inputs 1 and 2, 3 and 4, etc. Note: you can't connect a mic and a Line signal (CD, Synth...) in the same
input. The clock can be configured internally or externally.

In the ‘Output & Monitoring’ tab, you can assign an output to the rack’s two VU meters and especially the direct monitoring volume and pan adjustment of each input and also for each output. This lets you create many submixes and to assign them to the physical outs (1 to 8). This comes in handy when the singer wants more guitar in his/her headphones or the drummer more bass: this way everyone has their own output and mix, and everyone's happy. Because the UX8 has a second headphone out (outputs 3 & 4), it's really easy to make a submix for any musician who comes to your place to record.

Gearbox, the amp modeling software , also has its own adjustments for volume and pan.
