class A/de class B (selon le cas) prescrites dans le réglement sur le brouillage
radioélectrique édicté par les ministere des communications du Canada.
18. Exposure to extremely high noise levels may cause permanent hearing
loss. Individuals vary considerably in susceptibility to noise-induced
hearing loss, but nearly everyone will lose some hearing if exposed to
sufficiently intense noise for a period of time. The U.S. Government’s
Occupational Safety and Health Administration (OSHA) has specified
the permissible noise level exposures shown in the following chart.
According to OSHA, any exposure in excess of these permissible limits
could result in some hearing loss. To ensure against potentially danger-
ous exposure to high sound pressure levels, it is recommended that all
persons exposed to equipment capable of producing high sound pres-
sure levels use hearing protectors while the equipment is in operation.
Ear plugs or protectors in the ear canals or over the ears must be worn
when operating the equipment in order to prevent permanent hearing
loss if exposure is in excess of the limits set forth here.

Ch 1: Introduction
1.1 Evolution of the TT24
Console
The professional live sound industry has been revolu-
tionized over the past few years by high-end digital con-
soles. However, mid-size digital consoles have tended
to emphasize studio applications with user interfaces
encumbered by features (i.e., DAW control) not critical
for live applications. Some of these consoles conceal
their real cost by requiring the purchase of additional
cards to supplement their limited physical I/O.

Ch 2: TT24 Interface
The TT24 has an intuitive easy-to-use interface. It
maintains an “analog mentality,” which leverages off the
engineer’s experience, while providing all the advan-
tages of digital functionality.
The design mandate for the TT24 console interface is
simply stated:
Provide quick, intuitive access to any primary live
mixing function with no more than two button
presses, both within easy reach of the engineer’s
two hands.
Make the Touchscreen menu structure flat: no
“forward” and “back” buttons or menus to wade
through to access the desired function.
The following sections summarize the TT24’s major
functional categories.
2.1 Channel Strip
Channel strip means one of the 24 vertical areas
bounded at the bottom by a fader and at the top by the
LINE mic/line level switch. Each channel strip can
control one input at a time from one of four banks.
The top section of each channel strip (Figure 2-1)
has analog controls for mic/line input switching, 48V
phantom power activation, mic/line gain control, and
signal/overload LED indication.
Below that, each channel has a virtual potentiometer
(V-Pot), MUTE, SELECT, and SOLO backlit buttons,
and a 100 mm motorized fader.
The V-Pot, which performs multiple channel functions
(i.e., auxiliary sends and panning), consists of a push-
button rotary encoder surrounded by a 16-segment LED
ring (see V-Pot Control Area on page 8 for details).

2.2 Banks
The four Bank select buttons on the TT24 change the
function of the 24 channel strips to control the following
groups of channels (Figure 2-2):
ANALOG: 24 analog mic/line inputs
DIGITAL: There are 24 digital inputs from three ADAT
optical connectors on the rear panel (44.1/48 kHz).
At 96 kHz, there are 12 digital inputs from the three
built-in connectors; another 12 are available from the
optional ADAT I/O expansion card.
RETURNS:
1–8: Eight analog line inputs
9–16: Four internal stereo effects returns
17–24: Eight additional return channels from ex-
pansion card
MASTER: The masters bank uses the following channels:
1–12: Twelve Aux send masters
13–20: Eight Group masters
22–24: Left, Right, and Center/Mono Main outputs
2.3 V-Pot Control Area
The buttons to the right of the channel faders
(Figure 2-2) selects the current function for the chan-
nel V-Pots from the following:
• PAN: Left/Right and LCR panning control
• TRIM: Digital Trim has a range of ±15 dB
• METERS: High-resolution channel metering. Push
the V-Pot and the meter reverses to display com-
pressor gain reduction. Rotate the knob to control
the threshold settings.
• HPF: Push the V-Pot to engage/disengage the
HPF; rotate the knob to adjust frequency between
20–400 Hz.
• AUX SENDS 1–12: Rotate the V-Pot to control
send level; push the V-Pot to toggle pre/post fader
for that send.
• AUX PAN: Control panning of stereo linked axes
• AUX MODE: Aux mode is the only blue button on
the console and effectivelyturns the TT24 into a
powerful, dedicated monitor mixer by providing aux
mixing on the faders. In this mode, the 24 channel
faders act as channel aux sends and the 4 group
faders act as auxiliary master sends.

2.4 QuickMix Area
The upper right of the console, below the 5.5-inch
Touchscreen, is called the QuickMix area (Figure 2-3).
It consists of 12 push-button rotary encoders and eight
buttons, which provide fast navigation of the QuickMix
section
It is important to note:
• The only adjustable controls on the Touchscreen
are buttons that toggle a value on/off. All knobs
represented on the Touchscreen are controlled by
corresponding QuickMix knobs. If any of the 12
knobs are missing from the Touchscreen, the cor-
responding QuickMix knob has no function.
• Any Touchscreen knob colored white instead of
black denotes a dual function available by pushing
the corresponding QuickMix knob. This function
varies with the control.
The four QuickMix buttons on the left instantly dis-
play information for the selected channel:
• FAT: overview of all parameters of a selected
channel
• EQ: detailed control of equalizer settings
• DYN: detailed control of compressor/limiter and
gate/expander settings
• GRP/AUX: Group routing and Aux level control and
pre/post selection
The four QuickMix buttons on the right access con-
figuration mixing tasks:
• AUX MSTR puts all 12 Aux master sends on the
12 knobs.
• SNAP provides detailed control of the 99 snap-
shots including naming, locking and filtering. All
elements can be filtered out of a snapshot. For
example filtering out all but mute will provide mute
groups via snapshots.
• EFX accesses parameters and setup of the four
internal effects processors.
• MTRX accesses the 11x8 Matrix-Plus.
2.5 Snapshots
The TT24 includes a robust snapshot feature that
captures the state of the console:
• 99 snapshots
• fast store/recall surface control
• detailed snapshot filtering to store/recall only
selected parameters and channels
The snapshot controls are in the upper right area
beside the QuickMix buttons (Figure 2-3).

2.6 Flex Groups and Master
The TT24 has four Group channel strips and a master
strip (Figure 2-2). Each Group has a V-Pot (to control
group pan), MUTE, SELECT, SOLO buttons, and a
100 mm motorized fader on the console surface. The
four Group strips control either Groups 1–4 or 5–8.
The currently selected Group bank is indicated bythe
GROUP ASSIGN/SELECT buttons.
Changing the Group Bank
Press any of the GROUP ASSIGN/SELECT buttons to
select that Group bank. The GROUP ASSIGN/SELECT
buttons illuminate 1–4 or 5–8 and cause the faders and
buttons to snap to their previous Group bank settings.
Group Assignment
Press and hold a GROUP ASSIGN/SELECT button
and press the channel SELECT buttons to add/subtract
channels from that Group. This method is used for all of
the GROUP ASSIGN/SELECT buttons (Groups 1–8, L-R
and CTR/Mono).
Group Parameter Control
Press a GROUP SELECT button to access that
Group’s settings and controls in the QuickMix section
just like an input channel.
2.7 Matrix-Plus
Matrix-Plus is a unique and powerful 11x8 matrix
mixing tool that delivers extremely flexible matrix mix-
ing. The matrix can only be activated by pressing the
MATRIX button on the right side of the QuickMix area
(Figure 2-3).
Once activated, the matrix uses the Group outputs.
Like most 11x8 matrices, the 11 default inputs to each
matrix are Groups 1–8, Left, Right, and Center. However,
Matrix-Plus provides the unique ability to patch other
signals into the matrix. Press the desired Group Quick-
Mix knob to display the screen in the right side of Figure
2-4 to select the desired signals.
The available matrix input signals are:
• Analog inputs 1–24 pre/post fader
• Digital inputs 25–48 pre/post fader
• Line inputs 1–8 pre/post fader
• Internal effects returns 1L-4R pre/post fader
• Groups 1–8 Mono, Left, Right, Center (if available)
• Main Left, Right or CTR/Mono post fader
• Expansion card return 1–8
• Stereo inputs Left and Right pre/post fader
Each matrix also has up to 600 ms delay for delayed
stack applications.
2.8 Utility Area
At the top of the console, the UTILITY area contains:
Talkback: Mic preamp gain setting knob; signal (SIG)
and overload (OL) LEDs
Monitor: Analog level control for the Left, Right, Mono
TRS rear panel outputs
Phones: Analog level control for the front-mounted

2.9 TT Control Software
The TT control software expands the control possibili-
ties for the TT24 console by providing:
• Remote control of all TT24 functions from a PC con-
nected via USB.
• Improved metering and graphics than can be seen
on the Touchscreen.
• Remote Show/Venue/Preset management and con-
sole–>console backup/restore.
• Console firmware upgrade capability.
The TT24 connects to the PC via a USB cable (six-ft
cable supplied). The minimum PC requirements are
summarized below.
Table 2-1 Minimum PC Requirements
Screen Resolution Processor Speed Operating System
1024 x 768 600 MHz Windows 2000 or XP
The main screens of the TT control software mir-
ror and elaborate the Touchscreens. The TT control
screens can be set to operate independently or to track
the Touchscreen. When they are independent, two
users may control the TT24, one from the console and
one from the computer. To adjust this setting from the
Touchscreen (can also be adjusted from TT control):
press the QuickMix SETUP button, touch the GEN-
ERAL button from the MENU SELECTION screen, then
touch to select PC AUTO FOLLOW to synchronize the
TT control software with the Touchscreen (deselect the
checkbox to make them independent).
