Model

SPL Gain Station 1

Class A & Tube Microphone and Instrument Preamplifier

The GainStation 1 is a 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.

Clean Gain

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.

Tube Gain

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.

HiZ/Line Input

The instrument input is a discrete impedance converter that also operates in class A mode. The core is a low-noise field-effect transistor, which is ideally suited as an impedance converter due to its very high input resistance.

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.

AD Converter Module 1090

The 24 bit converter module provides an SPDIF output which is available as coaxial and optical output.

The internal sampling rate can be set with switches to 44.1, 48, 88.2 and 96 kHz. Other sampling rates (32, 176.4, 192 kHz) can only be set with an external synchronization signal.
