A FEW DEFINITIONS
PROJECT: The entire configuration file that you are working on, encompassing
all your created PRESETs and the PROJECT level information. A PROJECT can
contain from one to eleven PRESETs, including one VALET PRESET.
The PROJECT is the file that will be saved in your computer, and the file that
is uploaded to, and stored in the TwK™ DSP. TwK™ PROJECT files have the
extension "*.twkproj" when viewed in your computer's file browser.
PRESET: A specific configuration of DSP settings that is saved within a
PROJECT.
PRESETs are designated as "Disabled" or "Enabled". When Enabled, they are
available to be activated via the TüN™ software when the PC is connected, or via
the TwK's connected DRC controller when no PC is connected. PRESETs may
also be activated by pressing the Preset Toggle button located on the top of the
TwK™. When "Disabled", a PRESET is dormant and not able to be activated. It
must first be Enabled via the TüN™ software. A maximum of six PRESETs may be
Enabled at one time, plus a special preset called "VALET". A total of 10 PRESETs,
plus the VALET preset may be stored in a PROJECT file. Only one Enabled
PRESET may be Active at any time.
Each PRESET is shown in the TüN™ interface as a rectangular button along the
top edge of the dark gray frame. A new, blank PRESET can be created by clicking
the
symbol to the right of the PRESET button(s).
Each PRESET button also has a pull-down menu, which allows a PRESET to
be enabled/disabled, renamed, duplicated or deleted. The "Duplicate" function
allows you to create an exact copy of an existing PRESET, which you can then
modify without disturbing your previous PRESET.
You will also assign a color to each Enabled PRESET. This color will be displayed
on the DRC's LED when you activate that PRESET. This permits the user to easily
identify the PRESET being activated.
The order of the PRESETs can be rearranged at any time by selecting, dragging
and dropping the PRESET's button into the desired position.
VALET: a special PRESET that is called up by grounding the "Valet In"
connection located on the TwK's power connector. This allows you to install a
switch or an automatic relay trigger to activate this special PRESET, overriding
all other PRESETs while that connection remains grounded. This is useful for
creating a limited "VALET" mode with restrained output levels, for example.
Another example would be a special tuning that is automatically activated when
opening the roof on a convertible. You decide what you want this special PRESET
to do, and how it is activated.
DRC: An abbreviation for "Digital Remote Controller". Refers to a JL Audio
accessory which connects to the TwK™ (or other JL Audio products) via the
"JLid™ Port" on the JL Audio hardware. The TwK™ 88 and TwK™ D8 each include
a DRC-200 controller with indicator LED. This controller has an outer knob and
an inner knob, with push-button functionality. It can be discreetly mounted
within reach of the vehicle's driver. The LED can be located separately, so that it is
visible for PRESET identification.
