SPL Audio Gain Station 1 AD w/Digital Output

Microphone and Instrument Preamplifier

SKU: SPL00053 Categories: , , , Tags: ,


The GainStation 1 is a single channel high-end preamplifier featuring a 60V audio rail.

This preamplifier combines Class-A Clean Gain with sound-shaping Tube Gain in a compact design that allows for free placing close to the microphone or on top of an amplifier.

The GainStation 1 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.
