JL Audio TWK-88: 8-Channel DSP Processor with Analog and Digital Inputs/Outputs for Precision Audio Tuning

Description

System Tuning DSP 8-ch. Analog + Digital INPUTS / 8-ch. Analog OUTPUTS

System Tuning DSP with 8-ch. Stereo RCA Inputs / 2 Digital (Optical/Toslink and Coaxial) Inputs / 8-ch. Stereo RCA Outputs / 1 Digital Optical (Toslink) 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 lets you add dual configurable level controls, preset toggle, plus LED status reporting, all from the driver’s seat.

Connect your TwK™ via PC to the companion TüN™ Software Interface to take advantage these powerful features:

• Flexible input design:
  – 8 Differential-balanced, line-level input jacks (RCA) accept most line-level signals up to 7.1V (RMS)
  – Separate optical (Toslink) and coaxial digital inputs connect to any digital (S/PDIF) output.
• Flexible setup features:
  – Individual level trim, linkable for tuning
  – Individual polarity controls, linkable for tuning
  – Powerful input mixing tools
• 8 Powerful 10-band equalizers with flexible assignment capabilities:
  – 10-band graphic full octave EQ
  – 10-band parametric EQ
• Configurable EQ assignment delivers simple to complex tuning options:
  – Individual EQs may be assigned to each output
  – Multiple outputs may be combined and assigned to a single EQ
• 8 analog, line-level RCA output jacks (4V RMS), each with a full-featured tuning set:
  – Fully variable, high-pass and low-pass filters with selectable slopes from 6 dB/octave to 48 dB/octave (in 6 dB/octave increments)
  – Configurable delay settings, with separate entries for speaker distance plus offset control; expressed in time or distance units and fully linkable with other channels
  – Polarity control, fully linkable with other channels
  – Comprehensive level controls, fully linkable with other channels
• Optical (Toslink) jack provides a pass-through digital audio (S/PDIF) output from assignable input channels, with no signal processing applied.
• Provides a dedicated remote turn-on voltage output for activating aftermarket audio equipment.
• JLid™ Port allows connection of the included DRC-200 Digital Remote Controller to add dual configurable level controls, plus LED status reporting from the driver’s seat.
