JL Audio TwK-88 System Tuning DSP controlled by TüN software, 8-ch. Analog & Digital Inputs / 8-ch. Analog Outputs

System Tuning DSP with 8-ch. Stereo RCA Inputs / 2 Digital (Optical and Coaxial) Inputs / 8-ch. Stereo RCA Outputs / 1 Digital Optical Output

The TwK® 88 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® 88 includes flexible input/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® 88’s entire feature set by connecting it to your PC via USB, using the companion TüN® Software interface.

• Flexible input design with 8 differential-balanced, line-level analog inputs (RCA), accepting line-level signals up to 7.1V (RMS)
• Separate optical (Toslink) and coaxial digital inputs for connection to digital S/PDIF sources.
• Flexible input mixer allows input channels to be combined with full control over each input’s level and polarity.
• 8 banks of 10-band graphic or parametric equalizers with configurable EQ assignment
• Powerful crossover section with fully variable, high-pass and low-pass filters, crossover slopes are selectable from 6 dB/octave to 48 dB/octave (in 6 dB/octave increments)
• Configurable polarity and delay settings, with separate entries for speaker distance plus offset control; fully linkable with other channels, in any combination, for adjustment
• Precise output level controls, adjustable in 0.5 or 0.1 dB increments, fully linkable with other channels, in any combination
• 8 analog, line-level RCA output jacks (4V RMS)
• Optical (Toslink) output jack provides a pass-through digital audio (S/PDIF) signal from any pair of input channels, with no signal processing applied.
• Remote turn-on output (+12VDC) for activating aftermarket audio equipment.
• JLid™ Port allows connection of the included DRC-200 Digital Remote Controller to add dual configurable level controls, preset selection and LED status reporting from the driver's seat.
