What are the TwK™ 88 and TwK™ D8?:
The TwK™ products are powerful, user-adjustable System Tuning DSPs. 

JL Audio TwK DSP

Do I need a FiX™ 82 or FiX™ 86 to make a TwK™ 88 or TwK™ D8 work?: 
A FiX™ 82 or FiX 86 is not required. If you are working with an aftermarket source unit with analog RCA outputs, or S/PDIF digital outputs, you can connect these directly to the TwK™ inputs.  When using a factory source unit, a FiX™ 82 or FiX™ 86 can act as the interface between the factory source and the TwK™.  Learn more about the line of FiX™ OEM Integration DSPs.

How do you set up and adjust the TwK™ DSPs?:
JL Audio offers free PC software, called TüN™ to set up and adjust the TwK™ products. It is available for download here.


On what kind of devices does the TüN™ software operate?:
TüN™ software requires a PC running on Windows 7, Windows 8 or Windows 10.  A long USB cable is included with the TwK™ to connect to a PC.

Will TüN™ work on a Mac?:
TüN™ will not run natively on any Mac OS. However, it can be operated on a Mac using emulation software. TüN™ has been successfully tested on a Macbook Pro, with "Parallels Desktop 11 for Mac Pro", running Windows 10 OS. We have not tested all possible permutations of Mac/OS X/Windows/Parallels versions, so we offer this information without any guarantee of performance. 

Will TüN™ work on my iPad, iPhone, Android phone or tablet?:
TüN™ will not operate on any iOS or Android device. It may work on a Microsoft Surface device running Windows 10, although the TüN™ interface is not optimized for touchscreen only operation.

Can I make changes with TüN™ through Bluetooth®?:
No. The computer operating the TüN™ software must be plugged into the TwK™ DSP via USB.

How many bands of equalization do the TwK™ processors offer?:
80 bands of equalization are available. Both the TwK™ 88 and TwK™ D8 offer 8 EQ banks, each with 10 bands of fully parametric (or graphic) equalization. If desired, you can apply a bank of 10 bands of parametric EQ per output channel, or you can run multiple output channels from a single EQ bank. Read more on the TwK's very flexible Parametric Equalization and Graphic Equalization functions.

I set up my TwK™ and there is no sound:
Once configured using the Set Up Tool, the TwK™ is muted as a protection measure in case signal path routing is not properly set up or matching the installation lay out.  Simply click the mute icon and signal will pass.
