SPL GainStation 1 Model 2272

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 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).

• Clean Gain: Balanced instrumentation amplifier with DMPAs (Discrete Mic Pre Amp, 60 Volt rail) offering low distortion and high slew rate.
• Tube Gain: Equipped with a 12 AX 7 LPS tube for clear sound.
• HiZ/Line Input: Discrete impedance converter for instruments.
• Peak/FET Limiter: Includes a limiter for control.
• Polarity-Reversal: Allows for phase inversion.
• 48-Volt Phantom Power: Supports condenser microphones.
• LED Level Indicator: Visualizes signal strength.
• Switchable Impedance Adjustment: For microphone input (200 Ω, 1.2 kΩ & 10 kΩ).
• Discrete Operational Amplifiers: Class A technology for superior performance.
• Gas-Encapsulated Relays: Gold-plated contacts ensure reliable operation.
• Resistors with 0.1 % Tolerance: Ensures precision in the audio path.
• Power Supply with Double Shielding: Offers stable voltage regulation.
