5.2.2 Six-Band EQ 

The Master outputs can each access a six-band EQ 

comprised of a four-band EQ and two 

kill filters

 (see 

page 38) and a 31-band graphic EQ (see page 39). 

EQ Linking 

The Master LR and C/Mono is actually three EQs: LR 

is stereo linked (two EQs) while the Mono EQ (one EQ) 

can also be linked with LR. To link, hold down the LR 

and C/Mono channel 

SELECT

 buttons for two seconds 

(see 

Channel Linking

 on page 13). 

When the Master 

LR

 or 

C/Mono

 fader’s 

SELECT

 but-

ton is pressed with the EQ or OVERVIEW Touchscreen 

displayed, the EQ (and compressor) displayed on the 

Touchscreen is LR. If the LR and C/Mono are linked, 

changing the LR EQ also affects the Mono EQ. If they 

are not linked, the C/Mono EQ is independent. 

5.2.3 Compressor 

The Master compressor operates identically to the 

channel compressor (see page 40). 

The Master LR and C/Mono compressor is actually 

three compressors: the LR compressors are stereo 

linked while the C/Mono compressor can be linked, if 

desired. 

The Master compressor can be viewed from the 

Master OVERVIEW Touchscreen and adjusted on the 

COMPRESSOR Touchscreen. 

5.2.4 Fader Position in Signal Path 

The Master LR or LCR fader position is adjustable 

from post- to pre-compressor. In the pre-compressor 

position, the user can ride the master fader while main-

taining the output level protection of the compressor. 

The master fader position can be adjusted from the 

Master OVERVIEW Touchscreen. 

5.3 Aux Send 

Each Aux Send has the following signal path: six-band 

parametric EQ, and compressor. The position of the EQ 

and compressor can be reversed. 

5.3.1 Six-Band Parametric EQ 

The Master Aux Send EQs operate identically to the 

Master LR and C/Mono EQs (see page 39). 

If a pair of Aux sends is linked, their EQs are also 

linked: adjusting the EQ of one aux of a linked pair 

adjusts the other’s EQ. 

The Aux Send EQ can be viewed from the AUX 

MASTER and Aux OVERVIEW Touchscreens. The EQ is 

adjusted from the 6 BAND EQ Touchscreen. 

5.3.2 Compressor 

The Master Aux Send compressors operate identically 

to the channel compressors.

If a pair of Aux sends is linked, their compressors are 

also linked: adjusting one aux’s compressor parameters 

also adjusts those of the other aux. 

The compressor for the selected Aux Send Master is 

displayed from the AUX MASTER and the Aux OVER-

VIEW Touchscreens. Its settings are adjusted on the 

Aux Master COMPRESSOR Touchscreen. 

5.4 Flex-Group DSP 

There are a total of eight DSP blocks available for the 

Flex-Groups so each of the eight groups can use a block 

of DSP except VCA types (see page 26). Not all groups 

can use DSP at once if they are in multichannel group 

mode. The Group DSP contains a four-band EQ and 

compressor. The default order is EQ into the compressor 

but they can be reversed. 

5.4.1 Flex-Group Modes 

Each group can be configured as mono, stereo, LCR (if 

in LCR Mode), or VCA. The group type is set by a toggle 

button in the Group OVERVIEW Touchscreen. Each 

group’s mode can be configured independently. 

Mono Mode 

If the TT24 is in L/R+Mono mode, all groups are mono 

by default. Mono groups operate similarly to groups on a 

typical analog console: pre-pan mono signals are routed 

from the channels to the Groups using the 

GROUP AS-

SIGN

 switches. After group processing, the signal passes 

through the group 

MUTE

 switch, fader, and can then be 

routed to the Mono or LR Master outputs. A group pan is 

available for L/R positioning. Group signals are available 

to the Matrix (if enabled). 

Stereo Mode 

Stereo groups do not have a pan control. Signals 

are routed from channels to stereo groups using the 

GROUP ASSIGN

 switches but the signal is post-pan and 

the stereo image is maintained throughout the group 

signal path. After any group processing, the stereo group 

signal can be routed to the main 

L/R

 output after the 

Group’s 

MUTE

 switch and fader. Stereo groups can also 

be routed to the 

C/Mono

 output but the stereo signal is 

summed to mono. 

LCR Mode 

In LCR mode, the same three group modes are avail-

able along with LCR group mode, but they operate 

slightly differently. A mono group still receives its mono 

signal from the assigned channel, and can be routed to
