The DC-coupled module can encode and decode audio signals with extremely low noise, and CV signals with near-zero offset. Additionally, on-board sample clock allows for one-way ADAT output and the ability to be used standalone to interconnect eurorack systems.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eOptx v2 represents nearly two years of engineering and prototyping, and greatly improves upon the features and performance of Optx v1. The module has been completely redesigned from the ground up for the best overall performance possible in 10 HP.\u003c\/em\u003e\u003c\/p\u003e\n\u003cdiv class=\"wp-block-spacer\" aria-hidden=\"true\"\u003e \u003c\/div\u003e\n\u003ch3 class=\"wp-block-heading\"\u003eADAT Encoding \u0026amp; Decoding\u003c\/h3\u003e\n\u003cp\u003eMany computer audio interfaces are equipped with one or more pairs of ADAT expansion ports allowing for additional input and output channels. Optx v2 takes full advantage of these often unused ports, providing multi-channel connections directly to and from eurorack systems.\u003c\/p\u003e\n\u003cp\u003eThe module accepts any 8-channel ADAT encoded digital signal at the \u003cstrong\u003eRx\u003c\/strong\u003e TOSLINK jack (via lightpipe optical cable) and converts it into 8 discrete analog signals. Conversely, Optx v2 accepts 8 discrete analog signals and converts them into an 8-channel ADAT encoded digital signal available at the \u003cstrong\u003eTx\u003c\/strong\u003e jack.\u003c\/p\u003e\n\u003cp\u003eWhen used in conjunction with software such as Bitwig Studio or Ableton CV Tools, Optx v2 is an excellent interface not just for audio, but also control voltages like 1V\/oct pitch and gate signals, or LFOs, ADSRs and other modulators.\u003c\/p\u003e\n\u003cdiv class=\"wp-block-spacer\" aria-hidden=\"true\"\u003e \u003c\/div\u003e\n\u003ch3 class=\"wp-block-heading\"\u003ePrecision and Performance\u003c\/h3\u003e\n\u003cp\u003eOptx v2 has been fitted with high-performance op amp input buffers and professional-grade Cirrus Logic analog-to-digital converters with extremely low noise and distortion, maximum dynamic range, and excellent overall detail. The inputs and outputs have very precise level scaling with a range of 20 Vpp (±10 V). Thus a typical eurorack audio signal of 10 Vpp will translate to exactly -6 dBFS, while maintaining an equal amount of headroom.\u003c\/p\u003e\n\u003cp\u003eThe module’s high-quality analog outputs, \u003cstrong\u003eOUT 1-8\u003c\/strong\u003e, are DC-coupled and support both audio and CV (control voltage) signals at all times.\u003c\/p\u003e\n\u003cp\u003eThe module’s analog inputs, \u003cstrong\u003eIN 1-8\u003c\/strong\u003e, also accept both audio and CV signals. To ensure the best possible quality and precision, each pair of inputs has a front-panel switch that selects the conversion mode appropriate for each of these two signal types.\u003c\/p\u003e\n\u003cp\u003eIn \u003cstrong\u003eAUDIO\u003c\/strong\u003e mode, the selected input pair is AC-coupled by enabling high-pass filters within the ADC.
