plug. A polarized plug has two blades with one wider than the other.
A grounding-type plug has two blades and a third grounding prong.
The wide blade or the third prong are provided for your safety. If the
provided plug does not fit into your outlet, consult an electrician for
replacement of the obsolete outlet.
10. Protect the power cord from being walked on or pinched particularly at
plugs, convenience receptacles, and the point where they exit from the
apparatus.
11. Only use attachments/accessories specified by the manufacturer.
12. Use only with a cart, stand, tripod, bracket, or table specified by the
manufacturer, or sold with the apparatus. When a cart is used, use
caution when moving the cart/apparatus combination to avoid injury
from tip-over.
13. Unplug this apparatus during lightning storms or when unused for long
periods of time.
14. Refer all servicing to qualified service personnel. Servicing is required
when the apparatus has been damaged in any way, such as power-
supply cord or plug is damaged, liquid has been spilled or objects have
fallen into the apparatus, the apparatus has been exposed to rain or
moisture, does not operate normally, or has been dropped.
15. This mixer has been designed with Class-I construction and must be
connected to a mains socket outlet with a protective earthing connec-
tion (the third grounding prong).
16. This mixer has been equipped with an all-pole, rocker-style AC mains
power switch. This switch is located on the rear panel and should
remain readily accessible to the user.
17. This apparatus does not exceed the Class A/Class B (whichever is
applicable) limits for radio noise emissions from digital apparatus as
set out in the radio interference regulations of the Canadian Department
of Communications.
ATTENTION — Le présent appareil numérique n’émet pas de bruits
radioélectriques dépassant las limites applicables aux appareils numériques de
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 essen-
tial 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.
The TT24 Digital Live Console is a mid-size digital
mixer with an intuitive interface optimized for live
sound applications. We have used our extensive exper-
tise and experience designing analog mixers to produce
a powerful, easy-to-use digital console for a wide range
of applications and budgets:
• theaters and houses of worship
• permanent concert installations
• professional live music touring companies
TT24 maintains an “analog mentality,” utilizing the
engineer’s experience, while providing all the advan-
tages of digital functionality. With all the features of
high-end consoles, the TT24 is extremely cost effective.
The design mandate for the TT24 console user inter-
face 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.

1.2.1 DSP Functionality
The TT24 is loaded with DSP horsepower that is
distributed on inputs and outputs in an optimal manner
for live sound. The TT24 design team spent a great deal
of time implementing and allocating the TT24’s DSP to
satisfy the rigorous, real-time demands of live concert
applications:
24 Mic/Line Inputs

1.3 Terminology and
Conventions
The following terms and conventions are used
throughout this manual.
• Touchscreen and console controls are represented
in bold type using their exact spelling and capital-
ization (i.e., press the ANLG bank button).
• Touchscreen and console areas are represented by
capital letters in plain type (i.e., press the PAN but-
ton in the V-POT CONTROL area).
• Activate pertains to switches/buttons that toggle
between two values and means “press the button
until it lights.”
• Deactivate pertains to switches/buttons that toggle
between two values and means “press the button
until it is not lit.”
• ADC means analog-to-digital converter
• DAC means digital-to-analog converter
• Intercancel means that pushing one button simul-
taneously selects that button and automatically
deselects the previously selected button. One but-
ton is always active. For example, the Bank Select
buttons intercancel. Radio button is another term
often used to describe this behavior, originating
from the push buttons that selected radio stations
in pre-1960s cars.
The Touchscreen is a new interface to most audio
engineers that requires some new terminology.
• Touch pertains to selection on the Touchscreen
(i.e., Touch the EQ button).
• Select describes touching a button or checkbox such
that it is activated. This allows a single instruction
to describe this action without knowing the control’s
previous state. For example, if the control is not
selected, touching the control once selects it. If it is
already selected, no action is required.

4. Set the 48V switch to the down position if the mic uses
phantom power; set it to the up position otherwise.
Set the channel gain
5. Activate the PFL button (right of Figure 2-2).
6. Activate channel 1’s SOLO button (above fader) to
solo the channel.
7. Provide a representative signal to the mic, watch
the meters to the right of the Touchscreen, and
listen in phones (the phones level is in the UTILITY
area).
The solo level should be between -7 and -10 dBFS.
8. Press channel 1’s SOLO button again or CLEAR
SOLO (left of PFL) to unsolo.
Route channel 1 to Main output, Group 1, and Aux 1
9. Press and hold the L/R button in the GROUP AS-
SIGN area (Figure 2-3) and activate channel 1’s
SELECT button.
All the channel SELECT buttons light, indicating
that all channels are routed to the Main output. You
should hear your mic in the speakers connected to
MAINS OUT via the master fader.
Let’s route the mic through Group 1 instead of directly
to MAINS OUT:
10. Press and hold the L/R button in the GROUP AS-
SIGN area and deactivate channel 1’s SELECT
button (so it is not lit).
Channel 1 no longer sends signal to MAINS OUT.
11. Press and hold the Group 1 button in the GROUP
ASSIGN area and activate channel 1’s SELECT button.
The mic is now routed to Group 1.
12. Press and hold the L/R button in the GROUP AS-
SIGN area and activate Group 1’s SELECT button.
Group 1 is now assigned to LEFT and RIGHT
MAINS OUT.
Use the channel, Group, and Master fader to listen
to the mic signal in the speakers connected to
MAINS OUT.

Ch 3: Console Surface Controls
3.1.1 LINE
Push the LINE button down to access the 1/4-inch
line input and up for the XLR mic input. For permanent
installations that require alternate access to mic and
line inputs in the same channel, connect both inputs
and toggle between them via the LINE button.
3.1.2 48 V Phantom Power
Push the 48V button down to supply 48 VDC phantom
power, required by most condenser mics, to the chan-
nel’s XLR mic input. The TT24 can provide phantom
power to all 24 mic inputs simultaneously. Push the but-
ton up for dynamic mics that do not require phantom
power. The line input is not affected by the 48V phantom
power switch.
3.1.3 GAIN
The GAIN knob controls the analog amplifier that ad-
justs the input sensitivity of the mic or line input signal.
The gain range of the mic input is 0–60 dB; the line’s
range is -20 to +40 dB. A unity gain indication for the
line input appears at the 10:00 position (unity gain for
the mic input is fully counterclockwise). Dual-concen-
tric labels surround the knob indicating the appropriate
levels (mic outside, line inside).
3.1.4 OL and SIG
The green SIG LED lights when the selected mic/line
signal exceeds -15 dBu. The red OL LED lights when the
signal is 3 dB below clipping the ADC. The SIG and OL
LEDs remain lit only while the signal level is above their
corresponding thresholds.
3.1.5 V-Pot
The V-Pot displays and controls one of
the following functions at a time: pan,
HPF, Aux send levels, Aux pan (for linked
Aux sends), digital trim, and channel
metering. The function is assigned from
the V-POT CONTROL area.
The V-Pot has 15 LEDs in a ring from
7:00 to 5:00. They light clockwise as the
signal level increases unless otherwise
noted. The V-Pot also has a bottom red
LED used to indicate different functions
including meter clip, default settings,
on/off, etc. The 12:00 LED is also sometimes used to
indicate a nominal setting (i.e., pan set to center). Each
function’s specific behavior is discussed in V-Pot Control
Area on page 14.

The TT24 console surface is organized into the follow-
ing areas, each of which is discussed in this chapter:
• Channel Strips
• QuickMix
• Bank Select
• V-Pot Control
• Utility
• Flex-Groups and Master
• Solo
3.1 Channel Strip
The TT24 has 24 channel strips bounded at the bot-
tom by a fader and at the top by a LINE switch. Each
channel strip can control one input at a time from one
of four banks.
The top section of each channel strip (left of Figure
3-1) has the following analog controls that apply only
to the Analog bank: LINE mic/line input switch, 48V
phantom power switch, GAIN mic/line gain control, and
OL (overload) and SIG signal LEDs.
Below that, each channel has a virtual potentiometer
(V-Pot), MUTE, SELECT, and SOLO buttons, and a
100mm motorized fader (right of Figure 3-1).
The V-Pot knob, which performs multiple channel
functions one at a time, consists of a push-button rotary
encoder surrounded by a 15-segment LED ring (see
V-Pot Control Area on page 14).

Owner’s Manual
Owner’s Manual
3.1.6 MUTE
Push the MUTE button to toggle the channel between
muted (button lights) and enabled (not lit).
NOTE: Pre-fader Aux sends can be globally
changed to pre- or post-mute from the
SETUP-GENERAL Touchscreen (see page 46).
3.1.7 Bank/Channel Description Area
This area indicates the audio signal currently con-
trolled by the channel strip. Each channel strip can con-
trol one channel from one of the four banks at any given
time. For example, Figure 3-1 illustrates channel strip
1. Four channel names are listed in the Bank/Channel
Description Area:
• If the ANALOG bank is selected, strip 1 controls
analog Channel 1.
• If the DIGITAL bank is selected, strip 1 controls
digital Channel 25.
• If the RETURNS bank is selected, strip 1 controls
Line Input 1.
• If the MASTERS bank is selected, strip 1 controls
Aux Send 1.
3.1.8 SELECT
When lit, the SELECT button indicates this channel
is selected for:
• display and control of its parameters on the Touch-
screen.
• assignment to groups in conjunction with the
GROUP ASSIGN/SELECT controls (see Group and
Master Controls on page 19).
Channel Linking
Pressing and holding the SELECT buttons on an
odd/even pair of adjacent channels for two seconds
links their functions. A Touchscreen window requests
confirmation: “Link Channel X and Y?” Touch YES to
link the channels or CANCEL to abort the process. To
unlink channels, press and hold both SELECT buttons
for two seconds again. A Touchscreen window requests
confirmation: “Unlink Channel X and Y?” Touch YES to
unlink them or CANCEL to leave them linked.
After linking, the odd channel’s settings are copied to
the even channel; adjusting a setting on either channel
duplicates the setting on the other. The only exception
to this rule is panning. The pans are inversely related
between linked channels: Panning one channel fully left
pans the other fully right; panning one channel to 10:00
pans the other to 2:00.
True stereo compression applies to linked channels so
the summed signal is delivered to the stereo compressor.
3.1.9 SOLO
Press the SOLO button to solo the channel. This yel-
low backlit button lights when the channel is soloed.
The PFL/AFL global selection is done in the Solo master
section (see Solo Area on page 19).
The default Solo behavior is to allow multiple soloed
channels. However, enable EXCLUSIVE SOLO mode (in
the SETUP-GENERAL Touchscreen) to have each Solo
selection deactivate the previous one. In EXCLUSIVE
SOLO mode, pressing CTRL+SOLO solos additional
channels.
3.1.10 Channel Fader
The motorized 100mm fader controls the channel
level. Its function depends on the selected Bank (see
Bank Select Area below).
In Aux Mode (page 15), the fader controls the level
of the channel Aux sends 1–12 and depends on the Aux
selection in the V-POT CONTROL area (see page 14). It
is variable from -∞ to +10 dB in logarithmically scaled
steps.
3.2 Bank Select Area
The four Bank Select buttons (ANLG, DGTL, RTNS,
MSTR) change the mapping to the 24 channel strips
(Figure 3-3). The four buttons intercancel and one is
always active. All channels retain their settings between
Bank changes.
3.2.1 ANALOG
Press the ANLG but-
ton to select the ANALOG
bank. The button lights red
and the 24 analog mic/line
inputs are assigned to chan-
nel strips 1–24.
3.2.2 DIGITAL
Press the DGTL button to
select the DIGITAL bank.
The button lights green and
the DIGITAL inputs are as-
signed to the channel strips
1–24.
At 44.1/48 kHz, there are 24 digital inputs from three
ADAT optical connectors on the rear panel. At 96 kHz,
there are 12 digital inputs from the three built-in ADAT
optical connectors.

3.2.3 RETURNS
Press the RTRN button to select the RETURNS bank.
The button lights red and the following inputs are con-
trolled on the channel strips:
1–8: Eight analog line inputs (TRS connectors on rear
panel) 9–16: Four internal stereo effects returns 17–24:
Return channels from expansion cards
3.2.4 MASTER
Press the MSTR button to select the MASTERS bank.
The button lights green and the following inputs are
controlled on the channel strips:
1–12: Twelve Aux send masters 13–20: Eight Group
masters 22–24: Left, Right, and Center/Mono Main
outputs
NOTE: The Left and Right faders are always linked. The Left-Right
and Center/Mono faders may be linked as needed.
3.2.5 USER BANK
A customizable user bank allows you to compile a
new bank of 24 faders containing any of the channels
included in the 4 primary banks (ANLG, DGTL, RTNS,
MSTR).
To access the user bank for mixing simply press the
ANLG and DGTL bank select buttons simultaneously.
They will both illuminate and the faders will snap to
their current settings, indicating the
TT24 is in the user bank. See section
6.13.5 for more information on config-
uring the user bank.
3.3 V-Pot Control
Area
The buttons to the right of the
channel faders assign the current
function to the channel V-Pots. These
include the four V-POT CONTROL
buttons (PAN, TRIM, METERS,
HPF), AUX SENDS 1–12, and AUX
PAN (see Figure 3-4). These buttons
all intercancel so only one can be ac-
tive at a time.
AUX PAN operates for stereo-
linked Aux sends only, and does not
deselect the selected Aux send but-
ton. When selected, a single LED illu-
minates around the V-Pot to indicate
the pan position.
The AUX MODE button is discussed in this section
because of its relevance to the other Aux buttons. How-
ever, it does not intercancel with the other buttons.
3.3.1 TRIM
Digital Trim, available only to the ANALOG bank, is
used to adjust the input level just after the ADC, and
channel meter, and before the channel DSP. This allows
setting the analog gain for the optimal A/D conversion
while still having an adjustable input level to the chan-
nel DSP. This also provides a method to lower the level
of all channel outputs and sends at once: Digital Trim is
before the Aux and Group sends in the signal flow.
The Digital Trim provides ±15 dB of attenuation or
gain, adjustable in 0.1 dB increments and is indicated by
a single, lit LED. When the Digital Trim is set to unity,
the top LED (12:00 position) and the bottom V-Pot LED
illuminate.
3.3.2 PAN
Pan position is indicated by a single, lit LED. When
the pan is exactly centered, the top LED (12:00 posi-
tion) and the bottom V-Pot LED illuminate.
LR or LCR panning is available on the ANALOG, DIGI-
TAL, and RETURNS banks and the eight groups (mode
dependent) of the MASTER bank.
3.3.3 HPF
The high-pass filter can remove unwanted
low frequencies from an input channel. The
filter cutoff frequency range is 20–400 Hz; the
default frequency is 80 Hz. The HPF has a
fixed slope of 18 dB/octave. The approximate
frequency is indicated by a single lit V-Pot
LED (frequency increases clockwise). Push
the V-Pot to toggle the HPF on/off; the bottom
red LED lights when the HPF is on. Press
the SELECT button on an individual chan-
nel, then press the EQ Quick-Mix button to
see the HPF frequency range as you turn the
V-Pot.
3.3.4 METERS
The V-Pot LEDs serve as a meter (indicat-
ing left to right) for the channel’s signal level.
The bottom, red LED illuminates to indicate
digital clipping (0 dBFS).
Push the V-Pot knob to toggle the meter
to show compressor reduction: the LEDs
now illuminate counterclockwise (the knob
controls the compressor threshold setting).
The bottom, red LED lights continuously to
indicate the compressor reduction mode of
the meter. This can be activated individually

per channel. Press and hold the METERS button in
the V-POT CONTROL area for two seconds to toggle the
meter modes for all channels between channel level and
compressor gain reduction.
3.3.5 AUX SENDS 1–12
The Aux send level for the channel is indicated by
multiple, lit LEDs. The level is variable from -∞ to +10
dB in logarithmically scaled steps. LEDs light from left
to right as the Aux send level increases. The maximum
Aux send level is indicated by all the V-Pot LEDs lit.
When the Aux send is set to unity (approximately 3:00),
the bottom V-Pot LED illuminates.
Rotate the V-Pot to control the selected send level for
that channel. Push the V-Pot to toggle the send pre-
/post-fader.
Press and hold consecutive Aux buttons in the V-Pot
Control area to link them for stereo operation. For ex-
ample, press and hold Aux 1 and 2, and the Touchscreen
displays “Link Aux Sends Aux 1 and Aux 2?” Touch OK to
complete the operation. Aux levels are copied from odd
to even Auxes when linking Aux sends. After linking,
adjusting one aux also adjusts the other. Pressing either
AUX SENDS button of a linked pair controls the stereo
level from the V-Pots and both AUX SENDS buttons
light. All Aux send DSP is also linked.
3.3.6 AUX PAN
Aux pan is indicated for stereo-linked Aux sends by a
single LED lit to illustrate the pan position. When the
Aux pan is set to center, the top (12:00 position) and
bottom V-Pot LEDs light.
Rotate the V-Pot to control the panning of stereo
linked Aux sends. AUX PAN does not intercancel
with the other V-Pot control knobs. When AUX PAN is
selected, the panning function corresponds with the
selected stereo Aux Sends. The pan for linked Aux sends
varies inversely: setting one to 9:00 automatically sets
the other to 3:00. If a mono Aux send is selected along
with AUX PAN, then no stereo position is displayed
on the V-Pot LEDs. Press AUX PAN again to return to
normal Aux send level operation.
3.3.7 AUX MODE
AUX MODE, the only blue button on the console,
effectively turns the TT24 into a powerful, dedicated
monitor mixer by using the 24 channel faders as chan-
nel Aux sends and the four Group faders as Aux masters.
Select an AUX SENDS button (it flashes) and each
channel fader is then used to control that channel’s Aux
send level.
In AUX MODE, the Group faders represent Aux Send
masters 1–12 in three banks:
Group
Fader 1
Group
Fader 2
Group
Fader 3
Group
Fader 4
AUX SENDS 1–4 1 2 3 4
AUX SENDS 5–8 5 6 7 8
AUX SENDS 9–12 9 10 11 12
Table 3-1 Group Faders control Aux Master Sends in
AUX MODE
For example, if AUX SENDS 3 is selected, it flashes
while AUX SENDS 1, 2, and 4 are lit solid to show their
masters are assigned to the Group faders. For linked Aux
sends, both AUX SENDS buttons flash when either button
is pressed while the other two in that bank are lit solid.
The TRIM, METERS, HPF, PAN, and AUX PAN but-
tons operate normally and still change the function of
the V-Pots.
GROUP ASSIGN buttons do not light in banks of four
in AUX MODE. However, pressing and holding a GROUP
ASSIGN button still allows Group assignment.
NOTE: See Group and Master Controls on page 19 for information
on the normal operation of the Group faders.
3.4 QuickMix Area
The QuickMix area (Figure 3-5) consists of the Touch-
screen, 12 push-button rotary encoders and eight buttons. It
also includes Snapshot control buttons, RUDE SOLO LED,
L/R and C/MONO meters, and the Engineer’s Utilities area.
It is important to note:
• The only adjustable controls on the Touchscreen
are buttons that toggle a value on/off and drop
down menus that allow a selection. All knobs rep-
resented on the Touchscreen are controlled by cor-
responding QuickMix knobs. If any of the 12 knobs
are missing from the Touchscreen, the correspond-
ing Quick-Mix knob has no function.
• Any Touchscreen knob colored white instead of
black denotes a dual function available by pushing
the corresponding QuickMix knob. The function
varies with the control.
The QuickMix buttons on the left are: FAT, EQ, DYN,
and GRP/AUX.
The QuickMix buttons on the right are: AUX MSTR,
SNAP, EFX, and MATRIX.
Each QuickMix button displays a Touchscreen for the
selected channel. If the selected channel does not contain
the selected function (i.e., Digital Inputs have no EQ), the
Touchscreen displays “This Channel Does Not Contain XX”
until another Touchscreen is accessed. The Touchscreens
are discussed in Chapter 6: Touchscreen and TT Control.

3.5.1 TALKBACK
The TALKBACK gain knob controls the input gain
of the rear panel TALKBACK microphone input. The
gain range is 0–60 dB. A green SIG (signal) LED and a
red OL (overload) LED behave identically to those on
the channel strips (see page 12). The talkback signal
is routed via the TALKBACK Touchscreen, accessed by
pressing UTIL and then touching the TALK-
BACK button. The Talkback signal can be
routed to any Matrix or Aux bus.
3.5.2 MONITOR
The MONITOR gain knob controls the level of
the Left, Right, and Mono monitor outputs. The
gain range is from off to +10 dB. These out-
puts contain the left, right, and monitor signal
selected in the MON. SOURCE Touchscreen, ac-
cessed by pressing UTIL and then touching the
MONITOR SOURCE button. When a solo button
is pressed, the solo signal is sent to the monitor
outputs instead.
3.5.3 PHONES
The PHONES gain knob controls the head-
phone output level, a stereo output identical to
the Monitor L/R outputs. The PHONES level is
independent of the MONITOR gain control.
3.6 Snapshots
The TT24 includes a robust snapshot feature that cap-
tures and restores the state of the console. The console
snapshot controls are in the top-right of the console
beside the QuickMix buttons (Figure 3-5). These fast
and intuitive surface controls can store/recall up to 99
snapshots. See “Appendix B: Snapshot Parameters Saved”
for a list of all the TT24 parameters saved in a snapshot.
More elaborate snapshot functionality is available on
the SNAPSHOTS Touchscreen (i.e., channel and param-
eter filtering; see page 42). This section discusses only
the console’s surface controls.
The SNAPSHOTS LCD displays the selected snapshot
(bottom-right in Figure 3-6). Use the up/down arrow
buttons to scroll through existing snapshots. The current
snapshot’s number is displayed in the SNAPSHOTS LCD
field next to the Touchscreen. The snapshot number
blinks in the SNAPSHOTS display before being recalled.
Press and hold the snapshot up or down arrows to
step through three numbers and then begin increasing
or decreasing in increments of fives to allow for faster
access to a desired snapshot.
Press RECALL to recall the blinking snapshot number
displayed in the LCD. When the RECALL button is
pressed, the snapshot parameters are loaded into the
TT24 and the LCD lights continuously. Press STORE
to save the state of the console to the current snapshot
(the last snapshot recalled).

3.7 Group and Master Controls
The TT24 has four Group strips and one Master strip
(Figure 3-8). Each Group has a V-Pot to control group
pan and the Group Mode, MUTE, SELECT, SOLO but-
tons, and a fader. The four Group strips control either
Groups 1–4 or 5–8. The currently selected Group bank is
indicated by the lit GROUP ASSIGN/SELECT buttons.
3.7.1 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.
3.7.2 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.
The SELECT button for channels assigned to a
group light when a GROUP ASSIGN/SELECT button
is held down.
A selected channel can also be assigned to groups by
selecting GRP/AUX in the QuickMix area to view the
Group/Aux parameters on the Touchscreen.
3.7.3 Group Parameter Control
Press a GROUP SELECT button to access that
Group’s settings and controls from the QuickMix section
just like an input channel.
3.7.4 Mute Groups
Eight dedicated mute groups are available for applica-
tions where muting groups of input channels quickly
with a single button is required. All channels from the
ANLG, DGTL, and RTNS bank can be included in a mute
group. Outputs are not available for mute groups.
The Mute groups on the TT24 use the group assign
area of the mixer’s control surface to assign channels to a
mute group as well as to activate/deactivate mute groups.
To assign input channels to a Mute Group:
Press and hold the CTRL button in the QuickMix area
and also press any one of the GROUP ASSIGN 1-8
buttons. When this is done, the Group Assign button il-
luminates and the Group Mute button blinks, indicating
the TT24 is in Mute Group Assign mode. Simply press
the channel mute button for any input to be included
in the Mute Group. You can press other Group Assign
buttons to configure any of the eight mute groups when
in this assign mode. Pressing the blinking Mute Group
MUTE button or lit Group Assign button will exit the
assignment mode.
To activate/deactivate Mute Groups:
Press the Group Mute button while holding the Group
Assign button to activate and deactivate mute groups.
All channel mutes will light when a mute group is suc-
cessfully activated.
Note: TT24 Mute Groups are unlike those on an
analog console in that they are destructive. When a
Mute Group is engaged, you can unmute an individual
channel with the channel mute button. This allows for
easier muting of groups and individual channels.
3.8 Solo Area

Ch 4: Rear Panel Connectors
4.1.2 LINE Inputs 1–24
These 1/4-in TRS connectors accept a balanced or un-
balanced line level input signal from almost any source.
The LINE button on the console surface should be in
the down position when using these connectors. The
LINE inputs appear on the ANALOG bank.
A balanced line level signal must be wired as follows:
• Tip = Positive (+ or hot)
• Ring = Negative (-or cold)
• Sleeve = Shield or ground
An unbalanced signal must be wired as follows:
• Tip = Positive (+ or hot)
• Sleeve = Shield or ground
4.1.3 INSERTS 1–24
These 1/4-in TRS connectors provide each channel
an analog send and return point. Use the INSERT jacks
to connect external serial effects devices (i.e., com-
pressors, equalizers) to an individual channel. These
connectors can also be used as post gain control, unbal-
anced channel direct outputs.
The INSERT points are after the GAIN control, and
just before the ADC. The send (tip) is low-impedance
and the return (ring) is high-impedance, allowing con-
nection to virtually any device.
Cables for this type of insert send/return function
must be wired as follows:
• Tip = Send (output to effects device)
• Ring = Return (input from effects device)
• Sleeve = Common ground (connect shield to all
three sleeves)
4.1 Analog I/O
Figure 4-1 shows the rear panel analog I/O connectors
except for the Group/Matrix outputs, which are shown
in Figure 4-3.
4.1.1 MIC Inputs 1–24
The TT24 microphone preamp was based on our
extensive knowledge and experience with those used in
the Digital 8•Bus, VLZ Pro, and Onyx Series mixers, but
optimized for a digital mixer.
These female XLR connectors accept a balanced
microphone input from almost any type of microphone.
The LINE button on the channel strip should be in the
up position when using these connectors. The MIC in-
puts appear on the ANALOG fader bank. Phantom power
(48 VDC) can be switched on for condenser mics setting
the 48V button to the down position.
The XLR inputs are wired according to the AES stan-
dard:
• Pin 1 = Shield or ground
• Pin 2 = Positive (+ or hot)
• Pin 3 = Negative (- or cold)
