Frequently asked questions
What problem does each unit solve?
The AFS2 eliminates feedback by targeting and suppressing specific problem frequencies with up to 24 filters per channel. The DI4 solves the problem of connecting unbalanced instruments and keyboards to balanced XLR systems and provides multi-channel mixing and routing capabilities.
Which is better for a small live band setup?
The DI4 is more practical for typical band setups because it consolidates four instruments into one rack unit with independent monitor mixing and XLR outputs to the FOH engineer. The AFS2 is only needed if you have persistent feedback problems that EQ alone cannot solve.
Can these units work together?
Yes. You could use the DI4 to route and convert multiple instruments to balanced signals, then send those through an AFS2 if feedback suppression is needed before the mixing console.
What skill level do I need to operate each?
The DI4 is straightforward for beginners—simply plug in and adjust levels and pans. The AFS2 is designed for intermediate to advanced users who understand frequency-based feedback suppression and can interpret real-time metering on the LCD display.
