SSL Station 1 + AD is a 60 V Class A single-channel microphone and instrument preamplifier with a 24-bit / 192 kHz ADC. The quality of the recorded track will determine the final result. As with the SPL GainStation 1, solving this problem in the preamplifier, with the aim of significantly improving the signal and robustly transmitting it throughout its base, requires a great deal of thought and engineering effort.

Its very compact design allows it to be placed freely outside the rack (for example, near the microphone). Musicians can easily place the GainStation 1 in a rack or amplifier.

The 1090 analog-to-digital converter module is an optional digital output for compatible SPL units (see below). It has a plug-and-play design and is easy to install.

It provides an S / P-DIF output with coaxial and parallel optical connectors. The core of the module is a 24-bit converter with a variable sampling rate of up to 192 kHz. The high-precision quartz oscillator ensures a clean, low-jitter master clock.

The internal sampling rate can be changed between 44.1, 48, 88.2, and 96 kHz. Other sampling rates (32, 176.4, and 192 kHz) are set via external synchronization. The converter can be synchronized with other digital devices via the S / P-DIF input. When there is a signal from the following devices, the internal oscillator will automatically turn off the external clock. Avoid interference.
