SPL GainStation 1 Microphone and Instrument Preamplifier with ADC

spl The SPL GainStation 1, is a compact high-quality single channel microphone preamp that features a generous range of recording settings for its price and size. There is a dual stage gain input, featuring both solid state and tube circuitry, 50Hz filter, a three stage variable impedance switch, phantom power, peek/FET limiter switch and an output level encoder too.

SPL GainStation 1 Features:

  • Separated Solid state and tube preamps. The tube preamp can be added to the solid state stage to add varying amounts of tube saturation from subtle to brutal
  • Peak/FET Limiter
  • Switchable Mic Input Impedance (200 Ohms, 1,2 & 10 kOhms)
  • Custom-made, fully discrete, class A op-amps (no off-the-shelf stuff here). 60V Rail operating voltage—twice as high as most common op-amps—for an incredible dynamic range.
  • All switch functions are handled by encapsulated relays with gold-plated contacts.
  • An extremely high amplifier slew rate of <40V/µs, ensuring clean transmission of high-frequency signal portions and rapid transients with virtually no clipping
  • An almost entirely DC-coupled signal path, making signal-degenerating condensers unnecessary.
  • An optimized layout guarantees the shortest possible signal paths, while generously proportioned grounding surfaces ensure low impedance and maximum shielding.
  • All resistors are within 0.1% tolerance and were selected after extensive listening tests.
  • A no-compromise power supply with extensive additional shielding and seven separately wound and regulated voltages.
  • A tube stage utilizing premium MKP foil condensers and a select 12 AX7 LPS tube for clear, dynamic audio.
  • Includes 24/192 AD converter and Lundahl input transformer
  • Made in Germany
