  • Dual stage Class-A and tube analogue preamps
  • Custom-made, fully discrete SPL Class A op-amps
  • Tube saturation level can be dialled in
  • 12AX7 LPS tube for clear, dynamic audio
  • Switchable polarity
  • 48v phantom power
  • LED level indicators
  • Switchable input impedance
  • High headroom 60V DC Audio Rail operating voltage
  • Extreme amplifier slew rate for rapid transients

Preamps such as the GainStation can amplify sources to a standard of quality that negates the need for copious EQ or compression later in the mixing process. More presence and substance is added to each signal, allowing them to cut through in a mix even at lower levels. Meanwhile lower-end signals remain transparent with clear intonation.

Three separate impedances are on offer and can be switched to match almost any microphone type from ribbon to large diaphragm condenser: 200 Ohms, 1,2 & 10 kOhms.

60V Rail Operation
GainStation1 from SPL rear view

GainStation harnesses the power of two preamplifier stages based on SPL’s own discrete op-amp design, all operating on a 60V rail. The high voltage value clocks in at almost double that of traditional preamp designs, and offers a highly superior dynamic range of 130dB.

Dual Stage Design
GS1 Gainstation features a dual stage design

The first of two stages is a super-fast Class-A clean stage built to capture sound in its purest form, while the secondary tube stage is built to offer sound shaping talents from subtle warmth all the way up to full on valve saturation.
