GainStation 8 Mk2

8 Channel Microphone and Instrument Preamplifier

The GainStation 8 Mk2 is the premium recording front end featuring 60V audio rail.

This preamplifier combines Class-A Clean Gain with sound-shaping Tube Gain bring the fullest sound palette to your recordings.

The GainStation 8 Mk2 is the premium recording front end, ensuring that any microphone and instrument signal is pre-amplified with the highest quality.

The quality of your recordings has a major influence on the subsequent mixing process – good recordings require less processing in later stages. Improved transparence and understandability can be achieved with less equalization and compression if the signals are recorded optimally, often allowing individual signals to be mixed at lower levels without compromising their presence.
This cutting-edge technology ensures that signals recorded with the GainStation 8 Mk2 have more presence and substance and will easily cut through a mix even at lower levels.

Extremely low-frequency signals are tight and transparent with clear intonation. Percussive transients are interpreted more precisely, which leads to a clearer rhythmic content and in turn a more solid rhythmic performance and perception.
The GainStation 8 Mk2 Class-A preamplifier stages are based on proprietary discrete op-amps operating on a 60V rail.

That doubles the voltage of traditional preamplifier designs, resulting in a superior 130dB dynamic range and an extraordinarily alive, detailed image.
The first amplification stage is the Clean Gain stage, so-called because this is an extremely fast Class-A stage exclusively built with discrete 60V rail op-amps. This stage is designed to capture the pure sound as is.
The GainStation 8 Mk2 offers effective sound-shaping capabilities most notably via the tube stage, which can be completely bypassed or continuously added to the Class-A preamp circuit, allowing everything from subtle warmth to a noticeable tube saturation effect.
The pre-output stage Peak and/or FET mode limiters can be used to protect an AD converter from clipping, or for example to add punch to drum tracks, which in turn reduces or in many cases even eliminates the need for subsequent compression.
The GainStation 8 Mk2 offers three input impedances to perfectly match the preamplifier to the microphones. The mic impedances are 200 Ohms, 1,2 & 10 kOhms.
  • Separated Class-A and tube preamps.
  • Tube saturation from subtle to brutal
  • A tube stage utilizing premium MKP foil condensers and a select 12 AX7 LPS tube for clear, dynamic audio
  • Peak/FET Limiter
  • Polarity Reversal
  • 48-volt phantom power,
  • LED level indicators.
  • Switchable Mic Input Impedance (200 Ohms, 1,2 & 10 kOhms)
  • Custom-made, fully discrete, Class A op-amps
  • 60V DC Audio Rail operating voltage—twice as high as most common op-amps—for an extended dynamic range.
  • Extreme amplifier slew rate of <40V/µs, ensuring clean transmission of high-frequencies and rapid transients
  • All switch functions are handled by encapsulated relays with gold-plated contacts.
  • 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
The big toroidal transformer is in a separate housing. All seven voltages are derived from separately windings on the custom-made power transformer. The external housing ensures maximum isolation from electrical and mechanical hum.
Optionally the GainStation 8 Mk2 can be equipped with Lundahl input transformers – either for all or for single channels or channel pairs.
