GainStation 1 5
Introduction
To accommodate portability, the optionally available SPL
GainBag ensures safe transport of the GainStation 1 and offers
additional storage for cables and an average-sized micro-
phone.
For more permanent installations, up to four GainStation 1‘s can
be rack-mounted in one optionally available 3-unit rack space
mounting frame.
Main technical features of the GainStation 1
• Custom-designed and built, fully discrete, class A op-amps (no
off-the-shelf stuff here). The GainStation‘s op-amps feature
60-Volt operating voltage—twice as high as most common
op-amps—for an incredible dynamic range.
• An extremely high amplifier slew rate of 200 V/microsecond,
ensuring clean transmission of high-frequency signal portions
and rapid transients with virtually no cut-off.
• 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 switching functions are handled by encapsulated relays
with gold-plated contacts.
• 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 power supply is of primary importance to audio quality;
its importance should not be underestimated.
• A tube stage utilizing premium MKP foil condensers and a
select 12 AX7 LPS tube for clear, dynamic audio.
