So, what can you do with TüN™, when connected to a FiX™ DSP?

• Apply 10-bands of user-defined Graphic EQ to each output signal. Yes, you can tune the system, after calibration. How cool is that!
• View the frequency response of all inputs from the OEM system in clear, graphical form. No need for other test equipment to troubleshoot calibration and signal issues.
• View the frequency response of the summed and corrected output signals. Get a clear view of the end result!
• Mute any input for troubleshooting and calibration optimization.
• Reverse the polarity of any input right from your laptop. Fix wiring errors with just a single click!
• Initiate a new calibration from your laptop. No need to access the FiX™ hardware!
• Defeat/Engage Delay Correction... great for demos!
• FiX™ 86 only: Apply high-pass filtering to the front and rear output signals. Creates a bandpass channel when used in conjunction with an amplifier's low-pass filter, allowing you to build 3-way active systems with any JL Audio full-range or system amplifer.

TwK Logo Thumbnail When used with a TwK™ DSP, TüN™ software controls the following features:

• Three available Project Levels: Basic, Advanced and Expert
• Preset Management: create and manage up to ten presets within each project, plus a Valet preset.
• Input and Output Channel labeling: alphanumeric entry allows you to name every input and output, for easy reference.
• Input Sensitivity for analog inputs (TwK™ 88 only): set your analog input levels for minimum noise and maximum clean level.
• Input Routing and Mixing: gives you full control over polarity and relative level, allowing for the creation of specialized channels, such as center channels and ambient rear channels.
• Eight EQ banks can be operated as eight 10-band graphic EQs or as eight incredibly powerful 10-band, fully parametric EQs, which can be flexibly assigned to multiple output channels or to a single output channel
• High Pass and Low Pass Filters: precisely control the bandwidth for each of the output channels with a choice of 6, 12, 18, 24 or 48 dB/octave slopes.
• Simplified Distance, Delay and Polarity controls: these simple-to-use tools help compensate for speaker distance and improve crossover performance and/or imaging and staging.
• DRC Setup: configures the included wired controller, just the way you want it.
• Signal Levels: allow you to fine tune the relative level of all channels in 0.1 dB increments.
