System Tuning DSP with Digital Optical Input / 8-ch. Stereo RCA Outputs / 1 Digital Optical Output
The TwK® D8 is a state-of-the-art digital signal processor engineered to deliver world-class system tuning capabilities in an easy-to-use format. Equipped with an advanced 24-bit DSP processor, the TwK® D8 is equipped with a digital optical (Toslink) input and connects directly to our FiX® 82 OEM Integration DSP, or any 2-channel digital (S/PDIF) output, to maintain an all-digital signal path.
The TwK® D8 is also equipped with flexible output options, 80 total bands of equalization and powerful mixing tools. The included DRC-200 Digital Remote Controller offers dual level controls, toggles up to six presets, and has an LED indicator.
Control the TwK® D8's entire feature set by connecting it to your PC via USB, using the companion TüN® Software interface.
