The F601A from Fredenstein is a high-performance professional microphone preamplifier. Its Zero-Negative-Feedback design improves low-frequency and transient reproduction. In addition, the F601A delivers detailed high-frequency information without being harsh. Its fully discrete Class-A gain stage with its high-performance Lundahl LL1578XL input transformer outperforms "classic" microphone preamplifiers by a wide margin. This combined with the F601A's low noise will provide professional sonic results.
