the limits for a Class B digital device, pursuant to part 15 of the FCC
Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This
equipment generates, uses, and can radiate radio frequency energy
and, if not installed and used in accordance with the instructions,
may cause harmful interference to radio communications. However,
there is no guarantee that interference will not occur in a particular
installation.
If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the
equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:

• Reorientorrelocatethereceivingantenna.

• Increasetheseparationbetweentheequipmentandthereceiver.

class A/de class B (selon le cas) prescrites dans le réglement sur le brouillage
radioélectrique édicté par les ministere des communications du Canada.

19.

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 danger­ous exposure to high sound pressure levels, it is recommended that all
persons exposed to equipment capable of producing high sound pres­sure 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.

TT24 DIGITAL LIVE CONSOLE

Ch 1: Introduction

Owner’s Manual

1.2 Summary of Features

• 24-bit/96 kHz mixing console designed for live
applications

1.1 Evolution of the
TT24 Console

The professional live sound industry has been revolu­tionized over the past few years by high-end digital con­soles. However, mid-size digital consoles have tended
to emphasize studio applications with user interfaces
encumbered by features (i.e., DAW control) not essen­tial 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 exper­tise 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 advan­tages of digital functionality. With all the features of
high-end consoles, the TT24 is extremely cost effective.

• 24 mic/line inputs with 4-band EQ/comp/gate/HPF/
polarity invert (can be stereo linked)

• Eight line inputs with 4-band EQ (can be stereo
linked)

• Instant recall of 99 snapshots with ltering

• Rear panel connections: 36x28 analog I/O (24

Mic/Line Inputs, 8 Line Inputs, 4 Tape Inputs) x (8
Matrix Outputs, 3 Main Outputs, 3 Monitor Outputs,
12 Aux Sends); 28x28 digital I/O (24 ADAT optical

I/O, 2 AES/EBU I/O, 2 S/PDIF I/O)

• QuickMix section with 5.5-inch LCD Touchscreen,
12 push-button rotary encoders, and QuickMix buttons

• 29 100mm motorized faders

• 28 multi-function V-Pots

• 12 Aux sends with 6-band parametric EQ (includes
dual kill lters) and compressor/limiter

• Left-Right and CTR/Mono outputs with 6-band
parametric EQ (includes dual kill lters), 31-band
graphic EQ, and compressor/limiter

• Aux Mode enables instant monitor mixing

• 11x8 Matrix-Plus with patchable inputs

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.

Please write your serial number here for future
reference (i.e., insurance claims, tech support,
return authorization, etc.)

Purchased at:

Date of purchase:

• Eight user-denable ex-groups

• Eight dedicated mute groups

• Dual-console linking for a maximum 96 input con-

sole (coming soon!)

• TT control software to control and view console
parameters via PC

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

• Polarity invert

• Variable High-Pass Filter

• Gate/Expander

• Compressor/Limiter

• 4-band parametric EQ

• Stereo linking

8 Line Inputs

• 4-band parametric EQ

• Stereo linking

Main Outputs (LEFT, RIGHT, CTR/MONO)

• Compressor/Limiter

• 6-band parametric EQ (includes dual kill lters)

• 31-band graphic EQ

• L/R + Mono or LCR modes of operation

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 capital­ization (i.e., press the ANLG bank button).

• Touchscreen and console areas are represented by

capital letters in plain type (i.e., press the PAN but­ton in the V-POT CONTROL area).

12 Aux Sends

• Compressor/Limiter

• 6-band parametric EQ (includes dual kill lters)

• Stereo linking

8 Flex-Groups with 8 Assignable DSP Blocks

• Compressor/Limiter

TT24 DIGITAL LIVE CONSOLE

• 4-band parametric EQ

• Mono, Stereo, LCR, and VCA modes of operation

8 Matrix Outputs

• 600 ms delay is available to matrix outputs

4 Internal Stereo Effects

• Reverb

• Gated Reverb

• Mono/Stereo/Ping-Pong Delay

• Chorus

• Flanger

• 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.

• V-Pot Control

• Utility

• Flex-Groups and Master

• Solo

3.1 Channel Strip

The TT24 has 24 channel strips bounded at the bot­tom 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

TT24 DIGITAL LIVE CONSOLE

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).

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 chan­nel’s XLR mic input. The TT24 can provide phantom
power to all 24 mic inputs simultaneously. Push the but­ton 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 amplier that ad­justs 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-concen­tric 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 specic behavior is discussed in V-Pot Control

Area on page 14.

12:00 LED

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).

True stereo compression applies to linked channels so

Owner’s Manual

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).

3.1.7 Bank/Channel Description Area

This area indicates the audio signal currently con-

trolled by the channel strip. Each channel strip can con­trol 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 Touch­screen.

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.

• 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
conrmation: “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

conrmation: “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.

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 chan­nel strips 1–24.

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 chan­nel 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 ow.

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

TT24 DIGITAL LIVE CONSOLE

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 cong­uring the user bank.

METER

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 ac­tive 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 illu­minates around the V-Pot to indicate

the pan position.

Figure 3-4 V-Pot Control Area

TT24 DIGITAL LIVE CONSOLE

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 posi­tion) and the bottom V-Pot LED illuminate.

LR or LCR panning is available on the ANALOG, DIGI­TAL, and RETURNS banks and the eight groups (mode
dependent) of the MASTER bank.

3.3.3 HPF

The high-pass lter can remove unwanted

low frequencies from an input channel. The

lter cutoff frequency range is 20–400 Hz; the
default frequency is 80 Hz. The HPF has a
xed 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 chan­nel, 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.

In AUX MODE, the Group faders represent Aux Send
masters 1–12 in three banks:

Group

Fader 1

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 ashes

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 ash when either button
is pressed while the other two in that bank are lit solid.

The TRIM, METERS, HPF, PAN, and AUX PAN but­tons 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.

3.3.6 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 ashes) and each

channel fader is then used to control that channel’s Aux
send level.

3.4 QuickMix Area

The QuickMix area (Figure 3-5) consists of the Touch­screen, 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 rep­resented 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.

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.

To activate/deactivate Mute Groups:

Owner’s Manual

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 suc­cessfully 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

The Solo area (Figure 3-9) has two buttons: CLEAR

SOLO and PFL.

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 applica­tions 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.

Ch 4: Rear Panel Connectors

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 in­puts 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.

TT24 DIGITAL LIVE CONSOLE

The XLR inputs are wired according to the AES stan­dard:

• Pin 1 = Shield or ground

• Pin 2 = Positive (+ or hot)

• Pin 3 = Negative (- or cold)

4.1.2 LINE Inputs 1–24

These 1/4-in TRS connectors accept a balanced or un­balanced 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., com­pressors, equalizers) to an individual channel. These
connectors can also be used as post gain control, unbal­anced 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 con­nection to virtually any device.

using standard consumer audio RCA cables. The signal

Owner’s Manual

can be routed to the MONITOR outputs with CD/TAPE
A selected as the source in the MON. SOURCE Touch-

screen (see page 49). This allows cueing intermission
music through the MONITOR or PHONES outputs.

The CD/TAPE A inputs can also be routed to the
MAINS OUT from the STEREO INPUT Touchscreen.

This allows playing music between sets over the main

PA speakers. When engaged, the QuickMix Area pro­vides input level adjustment for CD/TAPE A on a rotary

encoder.

Channel Insert jack

Direct out with signal interruption to master.

Insert all the way in to the second “click.”

STEREO

PLUG

For use as an effects loop.

(TIP = SEND to effect, RING = RETURN from effect)

Figure 4-2 Insert Jack

4.1.4 AUX SENDS

1–12 These 1/4-in TRS output connectors provide 12

balanced or unbalanced line-level signals for effects

devices or stage monitor ampliers.

4.1.5 LINE INPUTS 1–8 (RETURNS)

These 1/4-in TRS input connectors accept eight bal­anced or unbalanced line-level signals from an external
processor or other device. They can be used as addi-

tional line inputs or as aux returns. The LINE INPUTS
appear on channels 1–8 on the RETURNS bank.

4.1.6 MONITOR

These 1/4-in TRS output connectors provide three
balanced line-level signals that can be used to provide
another stereo (L, R outputs) or mono (M output) main
mix output or to monitor the CD/TAPE A or CD/TAPE

B inputs. See MONITOR SOURCE on page 49 for more

information.

Connect these outputs to the inputs of an amplier,
powered speaker, or recording device. Typically, the L

and R outputs are connected to active studio monitors
and the M output to an active oor wedge.

4.1.7 CD/TAPE A IN/OUT

These RCA jacks connect to the inputs and outputs of
a CD/tape device. The TAPE IN jacks accept an unbal-

anced signal from a tape recorder or other signal source

WARNING: Selecting L/R in the STEREO
INPUT Touchscreen for the CD/TAPE A input
can create a feedback path between TAPE IN
and TAPE OUT. Make sure your tape deck is
not in record, record pause, or input monitor
mode, and turn the tape level control all the

way down.

The CD/TAPE A outputs produce an unbalanced signal
that is tapped off the MAINS OUT. Normally, these are
connected to the inputs of a recorder, but they can be used
as two additional main outputs (i.e., for another zone).

4.1.8 CD/TAPE B Input

These 1/4-in TRS input connectors accept balanced
or unbalanced line level signals from the outputs of a

CD/tape player or virtually any stereo line-level source.

The CD/TAPE B input can be routed to the MAINS
OUT from the STEREO INPUT Touchscreen (see page 49).
This allows adding the signal to the MAINS OUT or just

playing music between sets over the main PA speakers.

4.1.9 TALKBACK MIC Input

This female XLR connector accepts an external

talkback mic input. It requires a dynamic microphone

because it does not supply phantom power. Use the

Talkback UTILITY Touchscreen to route the signal to
the desired outputs (see page 49).

4.1.10 MAINS OUT

These male XLR connectors provide balanced, line­level signals representing the end of the processing
chain, where the fully mixed music is sent to the amps
and speakers. LEFT and RIGHT connectors output
the left and right stereo signals, respectively, while the
CTR/MONO connector outputs the center signal (in

LCR mode) or the mono signal (in L/R+MONO mode).
