Frequently Asked Questions

It's remarkably quiet for its size and price, performing admirably well against some higher-end options, though a dedicated studio preamp will generally offer even lower noise.
While technically possible, the limited gain range might make it difficult to achieve a usable signal level with ribbons; a higher-gain preamp is generally recommended.
The pad is great for taming overly hot signals from certain contact mics or instruments, preventing clipping and preserving dynamic range.
