“The Gain Station combines a truly excellent microphone preamplifier with a musically sensitive tube stage, a high-impedance DI box and a very sophisticated limiter. It also has enough headroom to handle virtually any input or to drive any other piece of equipment without straining.” – Sound On Sound
“The GainStation 1’s solid-state and tube preamps sound very different from one another, empowering the user to sculpt a variety of hybrid tones. Combine that with the unit’s insane amount of gain and generous allotment of bells and whistles, and you’ve got a winner!” – Mix
Discrete high-end preamplifier that combines Class-A clean gain with high-sounding tube gain and operates with an operating voltage of 60 V
Class-A meets Tube
The GainStation 1 is a hybrid preamplifier consisting of a discrete Class A transistor stage and tube stage. The hybrid design of the preamplifier combines the advantages of semiconductors (high dynamics with low distortion, low noise) with the musical qualities of tube sound (pleasant high/overtone spectrum, beautiful three-dimensionality).
The Class A transistor preamplifier is based on our DMPA operational amplifiers, which operate with an operating voltage of +/- 30 V.
The preamplifier has a Butterworth Hi Pass filter, polarity inversion, impedance selection, 48 V phantom power and a limiter.
The Clean Gain stage is a balanced instrumentation amplifier built with our DMPAs (Discrete Mic Pre Amp, 60 Volt rail).
In Class A mode, both end transistors always remain in a conducting state, thus avoiding crossover distortion.
With a slew rate of over 100 V/µs, it is capable of amplifying even fast details and high frequencies cleanly and with low distortion.
The tube gain stage is equipped with a 12 AX 7 LPS. It impresses with good noise figures and an open and clear sound image.
As decoupling capacitor a WIMA MKP type is used, which is very generously dimensioned with 2.2 µF, in order to work clean and powerful also in the bass range.
Input & Output Stages
The input differential amplifiers are constructed with closely toleranced and thermally coupled transistor pairs.
The output stage operates as a current amplifier, which also offers pure class A operation with over 6mA quiescent current. DC voltage components are eliminated with an active servo circuit instead of coupling capacitors.
AD Input 2
The optional converter has two channels and can therefore convert an external mono signal in parallel with the GainStation 1.
