A REAL MIXER

Unlike standard computer I/O boxes based on a patch bay concept, the Lexicon Omega Studio is designed and built around the same paradigm as large-format recording consoles. An 8-input, 4-Bus, 2-output USB I/O mixer with inserts, instrument input, MIDI I/O and complete metering and monitoring functions gives you the freedom to record up to 4 tracks at once and mix without the need for additional mixing hardware.

This is what we're talking about. Play with the mixer and check the levels and balance. If that's ok then open up Cubase or whatever DAW you're using and check that balance as well.
