SPL Model 1090 - A/D Converter Option for SPL Mic Preamps and Channel Strips

The Analog/Digital Converter Module 1090 is an optional digital output for compatible SPL units with a plug-and- play design for easy installation. 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. Highly accurate quartz oscillators 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/PDIF input. The internal oscillators are automatically disabled when an external clock signal is present to prevent interference. An extremely effective voltage stabilizing circuit ensures that the converter continuously receives sufficient and stable voltage – an important prerequisite for clean, transparent audio.

The compact design of the input stage guarantees the shortest possible signal path to the converter. Overdimensioned grounding surfaces on both sides of the circuit board effectively reduce interference and ensure optimal separation between analog and digital components.

The converter module 1090 serves as an optional digital output for the following SPL units:

• Frontliner
• Channel One
• Track One
• Kultube
• GainStation1
• GoldMike MK2
