The TT control interface has knobs, buttons, graphs, and 

drop down menus, each described in the following sections. 

6.1.1 TT Control Knob 

The parameter value for each knob can be adjusted 

using two methods: 

•  Click on the knob, hold, and drag up/down to in-

crease/decrease the value, respectively. 

In Figure 6-1, the 

Trim

, 

HPF

, 

Fader

, and 

Pan

 knobs 

can be adjusted by this method. 

•  Double-click the value below the knob to highlight 

the field and enter a new value from the keyboard. 

The HPF field is highlighted in Figure 6-1. High 

and low limits are automatically enforced for each 

parameter. 

6.1.2 TT Control Buttons 

The TT control software has two types of buttons: 

• 

On/off or selected/unselected

An on/selected button has black letters over a 

light blue background (L/R in the GROUPS area of 

Figure 6-3). An off/unselected button has light gray 

letters over a dark blue background (

GROUPS 1–8

in Figure 6-1). Click the button to toggle its setting. 

• 

Light switch

A light switch toggles between two or more values 

located to the right of the switch. The selected 

value appears with black letters on a light blue 

background (

GATE

 in Figure 6-1). The unselected 

value(s) has gray letters on a black background 

(

EXPANDER

 in Figure 6-1). The switch position 

aligns with the selected value. Click anywhere on 

the light switch to toggle through the values (circu-

lar if more than two). 

6.1.3 TT Control Menus 

At the top of Figure 6-1, the 

Ch. 1 Analog

, 

Overview

, 

Menu

, and 

Files

 menus all have a small downward point-

ing arrow indicating menu items. Click anywhere on the 

name or arrow to open a standard Windows menu. 

In addition, the 

Ch. 1 Analog

 menu has larger 

up/down arrows on either side. Click on these arrows, 

or press the console up/down arrow keys, to increment/

decrement through the list without opening the menu. 

6.1.4 TT Control Graphs 

Graphs with numbers or letters in small diamonds 

indicate that they can be adjusted by clicking, holding, 

and dragging the points (the EQ, GATE, and Compressor 

graphs in Figure 6-1). 

In the EQ graph, each point behaves according to its 

EQ type. Since Band 1 is a shelf filter, its point (1 in 

Figure 6-1) can be dragged sideways to set the cutoff 

filter frequency and up/down to set the filter gain. The 

parametric filters can be dragged up/down to set the fil-

ter gain and sideways to set the center frequency. Hold 

the 

Alt

 key down, click on the point, and drag sideways 

to adjust the Q (left widens, right narrows). 

Each point also corresponds to numerical fields below 

the graph that display their current values. These fields 

can be set by double-clicking and typing in a number 

from the keyboard. Upper and lower bounds are auto-

matically enforced. 

6.2 Touchscreen Conventions 

The Touchscreen uses knobs, buttons, and sub 

screens, each described in the following sections. The 

FILES

 menu is the same for all Touchscreens. 

6.2.1 Touchscreen Knobs 

NOTE:

 The Touchscreen knobs cannot 

be touched and adjusted directly! They 

correspond to the QuickMix rotary encoders 

below the Touchscreen.  

Up to 12 Touchscreen knobs each with a function 

label and value field are available depending on the 

Touchscreen. The layout of these knobs corresponds to 

the QuickMix rotary encoders below the Touchscreen. 

Adjusting a QuickMix knob adjusts the corresponding 

knob’s parameter. If the Touchscreen has less then 12 

parameters, the bottom row of QuickMix knobs is used 

first, followed by the middle and top rows. Figure 6-2 

shows all three rows in use. 

Each QuickMix knob can also activate a push button 

to toggle between two values related to its primary 

parameter. For example, the push button for a channel 

Aux Send toggles it between pre- and post-fader. The 

knob’s push button capability (not active for all encod-

ers) is indicated by a white Touchscreen knob instead 

of the usual black (the bottom-left and right knobs in 

Figure 6-2).
