    The 1090 24-Bit / 192 kHz AD Converter Module from SPL is the optional converter module for adding digital capability to a number of SPL processors. 

    These are the: Frontliner, Channel One, Track One, Kultube, GainStation1 and GoldMike MK2 

    The 1090 Analog/Digital Converter Module is a plug-and-play module. It offers an S/P-DIF output with both coaxial and optical connectors in parallel. The heart of the module is a 24-bit converter with a variable sample rate of up to 192 kHz. Quartz oscillators help ensure a clean, low-jitter master clock. The internal sample rate can be switched between 44.1, 48, 88.2 and 96 kHz. Other sample rates (32, 176.4 and 192 kHz) are set by external syncronization.The converter can be synced to other digital devices via a S/P-DIF input. 

    The internal oscillators are automatically disabled when an external clock signal is present to prevent interference. The voltage stabilizing circuit ensures that the converter continuously receives sufficient and stable voltage - an important prerequisite for clean, transparent audio. The compact design minimizes the signal path to the converter. Grounding surfaces on both sides of the circuit board effectively reduce interference and ensure optimal separation between analog and digital components.
