Description

Fredenstein HD Reference | 2-Channel Microphone Preamp
Fredenstein
2-channel microphone preamp with 64dB of gain
Fully discrete signal path and Class A balanced output stage achieves a true-to-life sound
Current amplification circuit eliminates internal transistor capacitance, providing 920kHz of bandwidth
Experience warm, natural sound via zero-negative-feedback topology
Transformerless design won't color your sound
The Fredenstein HD Reference Microphone Preamplifier can be described as unique, revolutionary, and among the best performing mic pres of all time. Well almost unique. The internal topology was first introduced in the 500 Series Fredenstein HD PRE which features the new current mode, true Class A, zero negative feedback, 100% balanced circuit that uses 54 discrete premium transistors for gain. The HD REFERENCE goes a step further with 72 transistors and a ±24 volt power supply. The HD REFERENCE is also designed to be remote controlled (or not) and offers 1 dB gain steps shown clearly on the front panel.
Technical performance can only be described as extreme or exceptional. Extreme low noise (EIN - XX dB), exceptional low distortion (.XX% at 60 dB of gain), extreme bandwidth (-3 dB down at 900 kHz) and is can deliver +30 dBu at the outputs. And while it sports the holy grail, grand combination of high end specifications, The HD REFERENCE also outperforms typical tube preamplifiers in the area of smooth transition into saturation, due to the absence of negative feedback and the fast recovery inherent in the topology. In other words, it goes from pristine to 3 dimensional through rich and then power house depending on how hard one drives it.
Features include 1 dB stepped gain from 0 dB to +64 dB (using high reliability relays) indicated with a large 7 segment LED display. 3 high pass filter frequencies, 3 impedance settings, phantom power and polarity switching. Details like, automatic muting while phantom power is changing, to prevent thumps and damage to monitors is built in. There are also a pair of Direct Inputs for instruments with low noise discrete JFET inputs (2 meg ohm) and 0 to 40 dB of gain.
