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 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.

Chapter 1: Introduction

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

terface 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

is a mid-size digital mixer with an intuitive in-

• 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.

The design mandate for the TT24 console user 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.

Chapter 3: Console Surface Controls

The TT24 console surface is organized into the following 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 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 and SOLO buttons, and a 100

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

Mackie TT24 Digital Live Console Owner’s Manual Console Surface Controls

3.1.3 GAIN

The GAIN knob controls the analog amplifier 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 specific behavior is discussed in

NOTE: Pre-fader Aux sends can be globally changed to pre- or post-mute from the SETUP-

GENERAL Touchscreen (see page 91).

3.1.7 Bank/Channel Description Area

This area indicates the audio signal currently controlled 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.

• assignment to groups in conjunction with the GROUP ASSIGN/SELECT controls (see

Group and Master Controls

on page 40).

Mackie TT24 Digital Live Console Owner’s Manual Console Surface Controls

Channel Linking

Pressing and holding the SELECT buttons on an odd/even pair of 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 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.

Press the RTRN button to select the RETURNS bank. The button lights red and the following inputs are controlled 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

Mackie TT24 Digital Live Console Owner’s Manual Console Surface Controls

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.

3.3 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 button. When selected, a single LED illuminates 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.

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 flow.

However, it does not intercancel with the other buttons

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.

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 example, 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.

Mackie TT24 Digital Live Console Owner’s Manual Console Surface Controls

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 channel 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:

Table 3-1 Group Faders control Aux Master Sends in AUX MODE

Group Fader 1 Group Fader 2 Group Fader 3 Group Fader 4

AUX SENDS 1–4 1234

AUX SENDS 5–8 5678

AUX SENDS 9–12 9 101112

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 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 40 for information on the normal

operation of the Group faders.

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.

Mackie TT24 Digital Live Console Owner’s Manual Console Surface Controls

It is important to note

• The only adjustable controls on the Touchscreen are buttons that toggle a value on/off and dropdown menus that allow a selection. All knobs represented on the Touchscreen are controlled by corresponding QuickMix knobs. If any of the 12 knobs are missing from the Touchscreen, the corresponding QuickMix 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:

4.1.4 AUX SENDS 1–12

These ¼-in TRS output connectors provide 12 balanced or unbalanced line-level signals for effects devices or stage monitor amplifiers.

4.1.5 LINE INPUTS 1–8 (RETURNS)

These ¼-in TRS input connectors accept eight balanced or unbalanced line-level signals from an external processor or other device. They can be used as additional line inputs or as aux returns. The LINE INPUTS appear on channels 1–8 on the RETURNS bank.

Mackie TT24 Digital Live Console Owner’s Manual Rear Panel Connectors

4.1.6 MONITOR

These ¼-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 94 for more information.

Connect these outputs to the inputs of an amplifier, powered speaker, or recording device. Typically, the L and R outputs are connected to active studio monitors and the M output to an active floor 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 unbalanced signal from a tape recorder or other signal source using standard consumer audio RCA cables. The signal can be routed to the MONITOR outputs with CD/TAPE A selected as the source in the MON. SOURCE Touchscreen (see page 94). 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.

WARNING: Selecting L/R in the STEREO INPUT Touchscreen for the CD/TAPE A input can cre-

ate 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 ¼-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 95). 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 95).

4.1.10 MAINS OUT

These male XLR connectors provide balanced, line-level 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).

4.1.11 GROUP/MATRIX OUT

By default, these eight male XLR connectors provide balanced, line-level outputs for Groups 1–8. However, when the MATRIX mixer is active, each output can provide a separate mix of virtually any input source. See

Matrix Mix

Six built-in Toslink connectors (INPUTS A–C, OUTPUTS A–C) provide 24 channels of 24-bit digital, ADAT optical lightpipe I/O at 44.1/48 kHz sample rates. At 88.2/96 kHz, the signal is multiplexed (SMUX format), which reduces the number of I/O channels to 12.

The optional ADAT I/O Expansion Card provides additional Toslink connectors (Expansion INPUTS A–C, Expansion OUTPUTS A–C) for channels 13–24 when operating at 88.2/96 kHz. The following table summarizes the channels allocated under each sample rate, with and without the expansion card.

NOTE: Expansion cards are not yet available.

4.2.2 AES/EBU IN/OUT

AES/EBU IN is a female XLR connector that accepts a stereo AES/EBU digital input. A sample-rate converter can be enabled at the AES/EBU input to convert the incoming signal to the TT24’s current sample rate. The signal can be routed from the STEREO INPUT Touchscreen (see page 95).

AES/EBU OUT is a male XLR connector that produces a stereo AES/EBU digital output of the LEFT and RIGHT MAINS outputs. At 88.2/96 kHz sample rates, the AES/EBU port uses the double-fast method, so the digital I/O port is clocked at twice the speed to double the transmission rate (see page 92 for more information on Digital Setup options).

4.2.3 SPDIF IN/OUT

SPDIF IN is an unbalanced RCA connector that accepts a stereo S/PDIF digital signal. A sample-rate converter can be enabled at SPDIF IN to convert the incoming digital signal to the TT24’s current sample rate. The signal is then routed to the main L/R output from the STEREO INPUT Touchscreen as needed.

SPDIF OUT is an unbalanced RCA connector that produces a stereo S/PDIF digital signal of the LEFT and RIGHT MAINS outputs.

Mackie TT24 Digital Live Console Owner’s Manual Rear Panel Connectors

4.2.4 WORD CLOCK IN/OUT

WORD CLOCK IN is a BNC connector that receives a word clock signal from another device when the Clock Source is set to Word in the DIGITAL SETUP Touchscreen. Use this connector when multiple devices must all operate from an external master word clock. Use 75 Ω coaxial cable to connect a word clock signal to WORD CLOCK IN.

WORD CLOCK OUT is a BNC connector that produces a word clock signal at the TT24’s current sample rate. Use this connector to transmit the word clock to other devices when the TT24 is operating as the system’s master word clock.

4.2.5 MIDI IN/OUT

MIDI IN/OUT are standard 5-pin DIN connectors to connect to other MIDI devices. MIDI IN can receive MIDI Time Code (MTC) to synchronize with another device, and MIDI Program Changes to recall snapshots. MIDI OUT can send MIDI Machine Control (MMC) and MIDI Program Changes from snapshot recall.

NOTE: MIDI functionality is not yet implemented.

4.2.6 USB

This standard Universal Serial Bus connector allows a PC to run the TT control software, install firmware upgrades, share files between PCs, and backup files.

4.3 IEC Power Receptacle

This is a standard three-prong IEC power connector. Connect the detachable cord included in the TT24 shipping box to the power receptacle. Plug the other end of the cord into an AC outlet.

The TT24 has a universal power supply that can accept any AC voltage in the range 100–240 VAC. This feature, which alleviates the need for voltage select switches (and setting them correctly!), allows the TT24 to operate safely virtually anywhere in the world. Fondly nicknamed “Planet less susceptible to voltage sags or spikes, and provides better electromagnetic isolation and protection against AC line noise.

Chapter 5: DSP and Internal Effect Allocation

TECH NOTE:The TT24 uses 12 SHARC DSP chips with embedded algorithms. This DSP approach

differs from conventional digital audio workstations in that the algorithms are programmed as firmware on the DSP chips. The incoming audio signal is digitized by its ADC and then routed through the DSP chip whether or not processing is engaged. This ensures equal latency for all incoming audio sources.

This chapter discusses how the TT24 allocates its DSP and Internal Effects resources.

See Chapter 6: DSP and Effects Touchscreens.

for specific information about the

on page 58 for parameter reference.

5.1 Analog, Digital, and Line Inputs

Analog Inputs

Analog input channels 1–24 route to their DSP block immediately after the ADC and before routing to outputs, groups, and auxes. The signal flow is frequency high-pass filter, adjustable gate, EQ and compressor (the EQ and compressor order can be switched for each channel), channel fader, pan and assign sections.

Digital Inputs

The ADAT Optical digital input channels 25–48 have no DSP. Their signals enter the board, pass through the channel meter and can be routed to the Mains, Aux Sends, and Groups/Matrix as needed.

variable

NOTE: The UFX II expansion card provides additional DSP for these inputs.

Line Inputs

Each Line Input can access a four-band parametric EQ. Odd/even adjacent inputs can be stereo linked (see page 27).

Mackie TT24 Digital Live Console Owner’s Manual DSP and Internal Effect Allocation

5.2 Master L/R and C/Mono

The Master L/R and C/Mono bus has the following signal path: six-band parametric EQ, compressor, and master fader.

5.2.1 L/R+Mono and LCR Modes

The TT24 has two master mix operating modes

L/R+Mono:Stereo with an independent mono output. LCR: True LCR panning from the channels and busses.

L/R+Mono

In L/R+Mono mode, the left and right stereo signals are available at the LEFT and RIGHT outputs, the mono signal from the CTR/MONO output. Channels can be assigned to both outputs. The channel sends to CTR/MONO are pre-pan, so the channel pan setting has no effect.

The L/R and Mono master levels and processing are linked by default, but they can be independent (see page 27). When unlinked, the MASTER fader controls the LR output and the C/Mono fader (channel 24 on the MASTERS bank) controls the mono output (which can also be controlled on the Master OVERVIEW Touchscreen). When linked, all processing is linked and the Master fader controls all levels. A relative offset between LR and CTR/MONO may be set using the Master OVERVIEW Touchscreen faders or the faders for channel strips 22–24 in the MASTERS bank.

LCR

In LCR mode, the LEFT, CTR/MONO, and RIGHT outputs present the LCR signal. Channels can be assigned to LR, Center, or LCR. A channel assigned to Center only is routed pre-pan, so the channel pan does not affect the Center signal. Channels assigned to LR only are routed to the LEFT and RIGHT outputs using stereo pan positioning. Channels assigned to LCR are routed to LEFT, CTR/MONO, and RIGHT outputs using true LCR panning.

The LCR master levels and processing are linked by default but can be unlinked and processed independently by pressing the LINK button in the Master OVERVIEW Touchscreen. When unlinked, the MASTER fader controls the LEFT and RIGHT outputs and the C/Mono fader (channel 24 on the MASTERS bank) controls the Center output (which can also be controlled on the Master OVERVIEW Touchscreen). When linked, all processing is linked and the MASTER fader controls all levels. A relative offset between the LEFT-RIGHT and CTR may be set using the Master OVERVIEW Touchscreen or by using the faders for channel strips 22–24 in the MASTERS bank.

Mackie TT24 Digital Live Console Owner’s Manual DSP and Internal Effect Allocation

5.2.2 Six-Band EQ

The Master outputs can each access a six-band EQ comprised of a four-band EQ and two

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

When the Master LR or C/Mono fader’s SELECT button 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.

kill filters

on page 27).

(see page 78).

5.2.3 Compressor

The Master compressor operates identically to the channel compressor (see page 79).

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 (see page 53).

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 maintaining 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.

Mackie TT24 Digital Live Console Owner’s Manual DSP and Internal Effect Allocation

5.3.1 Six-Band Parametric EQ

The Master Aux Send EQs operate identically to the Master LR and C/Mono EQs (see page 53).

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. See page 53 for operational details.

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 OVERVIEW 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 56). 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 ASSIGN 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).

Mackie TT24 Digital Live Console Owner’s Manual DSP and Internal Effect Allocation

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 available 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 Center or L/R. However, it can also be routed to LCR by assigning it to both Center and L/R simultaneously, resulting in a true LCR pan.

In LCR mode, a stereo group receives its stereo signal such that channel pan is interpreted as left-right. This results in a true LR group, maintaining the stereo image throughout the signal path. After processing, the Group’s MUTE switch, and fader, the group can only be routed to the LEFT and RIGHT or MATRIX outputs.

If a group is configured as LCR, it receives a post-pan channel signal, such that the pan is interpreted as LCR. The group maintains a true LCR image through the signal path: assignable DSP, MUTE switch, and fader. The LCR group can be routed to the LEFT, RIGHT, and CTR/MONO outputs.

NOTE: Assigning the group to LR or C automatically assigns it to the other; it cannot be

routed to just LR or C or Matrix.

VCA Mode

A VCA group allows assigning channels, each at its own relative level, to a group whose overall level is controlled by a single fader. Any input channel can be assigned to a VCA group.

The VCA group fader modifies the level of assigned channels

fader

. This means that all post-fader sends for these channels are also affected

at the channel

by the VCA group fader. Both the VCA and channel faders modify the channel’s output. For example, if the channel fader is set to +5 dB and the VCA fader is set to -15 dB, the cumulative output of the channel is -10 dB.

Mackie TT24 Digital Live Console Owner’s Manual DSP and Internal Effect Allocation

However, any fader at negative infinity or muted is not affected by a VCA fader. For example, if channel 1 is set to negative infinity, the output of the channel is muted regardless of the VCA fader setting. Likewise, if the VCA fader is at negative infinity or muted, the assigned channels are muted, regardless of their fader position.

A single input can be assigned to multiple VCA groups and it will be affected by all VCA faders. The resultant signal is the sum of the channel and its VCA faders. The maximum gain from summation is 10 dB.

The VCA group fader has MUTE, SOLO, and SELECT buttons. When the VCA Group is muted or soloed, the channels assigned to the VCA group are also muted or soloed. The channel’s MUTE and SOLO buttons blink and the VCA Group’s MUTE and SOLO buttons are lit solid.

5.4.2 Group DSP Allocation

Mono, stereo, and LCR groups can access DSP but VCA groups cannot. Eight units of group DSP are available and each Group mode requires a different number of units: Mono = 1, Stereo = 2, LCR = 3. Since the TT24 can have up to 8 LCR groups, there is not enough DSP to cover all group routing in all cases.

The Group OVERVIEW Touchscreen has a GRP DSP AVAILABILE meter that displays the group DSP (in 1 unit increments) available (see page 74 for more information).

When a group’s mode is changed, the DSP is automatically updated if necessary. If there is insufficient DSP available to make the adjustment, a warning appears: “There is not enough DSP to change the mode of the selected group. Change the mode and remove group processing?” Touch REMOVE to remove group processing and change the group mode, or touch CANCEL to leave the group in its current mode and DSP allocation.

Four-Band Parametric EQ

The Group’s four-band parametric EQ operates identically to the channel’s (see

Four-Band Equalizer

on page 76).

The Group mode setting determines the number of EQ sections: Mono = 1, Stereo = 2, LCR = 3. Stereo and LCR groups have linked EQ sections to implement their multichannel format. The Group EQ applies to all group channels.

The Group Parametric EQ can be viewed from the Group OVERVIEW Touchscreen and is adjustable from the Group’s 4 BAND EQ Touchscreen.

Mackie TT24 Digital Live Console Owner’s Manual DSP and Internal Effect Allocation

Compressor

The Group’s compressor operates identically to the channel’s (see on page 53).

The Group mode setting determines the number of Compressor sections and DSP units required: Mono = 1, Stereo = 2, LCR = 3. Stereo and LCR groups have linked Compressor sections to implement their multichannel format. The Group Compressor applies to all group channels.

The Group Compressor can be viewed from the Group OVERVIEW Touchscreen and adjusted from the COMPRESSOR Touchscreen.

5.5 Matrix Output

Each Matrix output has an adjustable delay.

5.5.1 Delay

Each Matrix output has a 600 ms delay to allow time alignment of multiple speaker groups in a large venue (see

Delay

Compressor

on page 89).

5.6 Internal Effects Processors

The internal EFX have four independent mono input/stereo output effects processors that are adjusted from the EFX Touchscreens, accessed by pressing the EFX button or from their associated returns OVERVIEW Touchscreens. Each processor can utilize one of the following effects: Reverb, Mono Delay, Stereo Delay, Ping Pong Delay, Chorus, or Flange. Each effect has a post with high- and low-shelf filter, and one parametric mid

The internal effects can be fed from any of the Aux Sends or the Matrix Outputs. By default, the four effects processors are fed by Aux Sends 9–12. Routing is accomplished on the EFX Touchscreen (see

Mackie TT24 Digital Live Console Owner’s Manual

Chapter 6: Touchscreen and TT Control

Most of the TT24’s configuration occurs on the Touchscreen and/or the TT control software. This section discusses the general conventions for both interfaces. Since the TT control software screens mirror and elaborate the Touchscreens, they will not be discussed except to define their functional differences.

In both the Touchscreen and TT control, the Ctrl key has a useful function: Press and hold the Ctrl key and adjust any TT control parameter to restore its default value. For example, press and hold Ctrl and adjust a Pan knob to set it to the center position, or adjust an EQ Gain knob to set it to 0 dB.

NOTE: The Touchscreen and TT control screens can be synchronized, so displaying a new

screen on one displays the corresponding screen on the other, or independent, allowing two engineers simultaneous access to the console. They are synchronized by default. See page 91 to toggle this setting.

6.1 TT Control Conventions

The TT control software expands the TT24’s control possibilities by providing

• Remote control of all functions from a PC connected via USB

• Improved metering and graphics than can be displayed on the Touchscreen

• Remote Venue/Preset management and console–>console backup/restore

• Console firmware upgrade capability

• Detailed Snapshot management

The TT24 connects to the PC via a USB cable (six-ft cable supplied). The minimum PC requirements are summarized below.

Table 6-1 Minimum PC Requirements

Screen Resolution Processor Speed Operating System

1024 x 768 600 MHz Windows 2000 or XP

The TT control interface has knobs, buttons, graphs, and drop down menus, each described in the following sections.

Mackie TT24 Digital Live Console Owner’s Manual Touchscreen and TT Control

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 increase/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.

Figure 6-1 TT Control software screen

Mackie TT24 Digital Live Console Owner’s Manual Touchscreen and TT Control

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 (circular 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 pointing 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 filter 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 automatically enforced.

Mackie TT24 Digital Live Console Owner’s Manual Touchscreen and TT Control

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 corre-

spond 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 encoders) is indicated by a white Touchscreen knob instead of the usual black (the bottom-left and right knobs in Figure 6-2).

Figure 6-2 6-Band EQ Touchscreen

Mackie TT24 Digital Live Console Owner’s Manual Touchscreen and TT Control

6.2.2 Touchscreen Buttons

There are two types of Touchscreen buttons:

• On/off or selected/unselected

An off/unselected button has black letters over a white background (SOLO in Figure 6-3). An on/selected button has white letters over a black background. Touch the button to toggle its setting.

•Light switch

A light switch toggles between the values located to the right of the switch. The selected value appears with black letters over a white background (ALL ACTIVE in Figure 6-3). The unselected value has white letters over a black background (ALL OUT). The switch position aligns with the selected value. Touch the switch to toggle the value.

Figure 6-3 MATRIX MIX Touchscreen

6.2.3 Touchscreen Name and Channel/Function

The name of the current Touchscreen is displayed in the top-center of the screen (MATRIX MIX in Figure 6-3). Some screens are specific to the selected channel or function. For example, the Analog and Effect Return OVERVIEW screens are different. The currently selected channel/function appears in the upper-left of the Touchscreen (Mtx C in Figure 6-3). Up and down arrows appear on either side of the selected channel that can be touched to increment or decrement the selected channel. Pressing the up/down QuickMix arrows also increments/decrements the field.

Mackie TT24 Digital Live Console Owner’s Manual Touchscreen and TT Control

6.2.4 Sub Screens

Some functions require one or more sub screens to adjust all parameters. These screens are accessed by touching a button or an area, such as an EQ graph. After viewing and adjusting parameters on the sub screen, return to the previous screen by pressing the hardware button that displayed the original Touchscreen.

6.3 Overview Touchscreens

There are seven variations on the OVERVIEW Touchscreen: Analog, Digital, Line, Effect Return, Aux, Group, and Master. To display these screens, press the FAT QuickMix button and

• select the desired channel’s bank and press its SELECT button;

6.4 Four-Band Equalizer

Figure 6-12 Analog Channel 4 BAND EQ

The 24 Mic/Line inputs, eight additional Line Inputs, and eight Flex-Groups can each access a four-band EQ. The four bands can be configured in two ways

• Bands 1–4 are identical with standard parametric controls: Gain, Frequency, and Q.

• Bands 2 and 3 are standard parametric filters while bands 1 and 4 can be individually set to be low- and high-shelf filters, respectively. This configuration is common on many analog consoles.

The entire EQ function can be switched in/out of the DSP chain from the Touchscreen, allowing an A/B signal comparison.

Select an analog channel and press the EQ QuickMix button to display the 4 BAND EQ Touchscreen. The Band 1 and 4 types are toggled from light switch buttons. The graph summarizes the EQ settings.

Gain

Each of the four filter's GAIN is adjustable ±15 dB in 0.1 dB increments. Each band defaults to zero gain.

Frequency

The FREQ parameter determines the filter’s center frequency, at which the gain setting is applied. FREQ is adjustable from 20 Hz to 20 kHz in scaled steps. For shelf-filter bands, the FREQ setting designates the half-power frequency: the frequency at which the power has decreased to half its maximum.

Mackie TT24 Digital Live Console Owner’s Manual Touchscreen and TT Control

The default frequencies for each band are

•Band 1: 80 Hz

•Band 2: 500 Hz

•Band 3: 2 kHz

•Band 4: 10 kHz

HPF Freq

The HPF FREQ field displays the value of the HPF set from the V-POT CONTROL area.

Q (Bandwidth)

The Q control adjusts the

width

of a parametric filter band and allows a wide or narrow boost and cut. Q is measured from the half-power points of the filter on both sides and is adjustable in the range 0.1–2.0 octaves in scaled steps.

NOTE: Bandwidth and Q are often used as synonyms but are a source of frequent

confusion because their values are inversely related. As the bandwidth widens and increases in value, the Q value decreases.

The graph summarizes the compressor’s parameter settings.

Mackie TT24 Digital Live Console Owner’s Manual Touchscreen and TT Control

Threshold

The THRESH control adjusts the level above which attenuation begins. It is adjustable in the range -60 to 0 dBFS in increments of 0.1 dBFS; the default value is 0 dB.

Ratio

The RATIO control sets the rate of gain reduction applied to the signal as it exceeds the threshold. The ratio can vary between gentle compression and peak limiting. The ratio range is 1:1 (no gain reduction) to the maximum of ∞:1 (peak limiting). The default setting is 1:1.

Attack

The ATK control varies the time the compressor takes to begin gain reduction after the signal exceeds the threshold. The ATK time range is 1–300 ms and the increments are scaled such that the faster attack settings have finer adjustments. The default setting is 15 ms.

Release

The REL controls the time the compressor takes to stop applying gain reduction after the signal decreases below the threshold. The REL time range is 50 ms to 3 s. The default setting is 200 ms. REL is scaled such that the faster release settings have finer adjustments.

Gain

The GAIN control sets the gain applied to the signal after the compressor. This allows GAIN range is 0–20 dB in increments of 0.1 dB. The default setting is 0 dB.

The THRESH control adjusts the level below which attenuation begins. It is adjustable in the range -60 to -1 dBFS in increments of 0.1 dBFS. The default threshold value is

Range/Ratio

In Gate mode, the RANGE control sets the amount of attenuation that occurs when the signal drops below the Threshold. The RANGE is variable from

100 dB to -1 dB in increments of 0.1 dB. The default is -100 dB.

In Expander mode, this setting is called RATIO and sets the expansion gain reduction ratio from 1:1 to 1

Hold

∞. The default is 1:∞.

The HOLD control adjusts the time the Gate/Expander stays open after the signal drops below the threshold before gain reduction begins. HOLD is adjustable in the range 0–5 s; the default is 0 s.

Mackie TT24 Digital Live Console Owner’s Manual Touchscreen and TT Control

Attack

The ATK control adjusts the time for the gate to open and pass the signal through once the signal exceeds the threshold after reduction has occurred. ATK is adjustable in the range 1–30 ms. ATK is scaled such that the faster settings can have finer adjustments. The default ATK is 1 ms.

Release

The REL control adjusts the time for the gate to close and begin gain reduction after the signal drops below the threshold and the hold time has passed. REL is adjustable from 50 ms to 3 s and is scaled such that faster settings can have finer the adjustments. The default REL time is 250 ms.

Expander/Gate Mode

The EXPANDER/GATE switch toggles from Gate to Expander. It is accessible only from the GATE/EXP Touchscreen, not from DYNAMICS. In Expander mode, the, HOLD, ATK and REL controls operate the same as in Gate mode but the RANGE control is displayed as RATIO. This can produce smoother sounding gain reduction in many situations.

In Expander Mode, RANGE is replaced by RATIO that sets the rate of gain reduction as the signal drops below the Threshold. Ratio is variable between 1:20 (maximum gain reduction) to 1:1 (no gain reduction). As RATIO approaches to 1:1, the resolution between values increases.

PRE FADER AUX SENDS GLOBAL

Pre-fader Aux sends can be globally changed to pre- or post-mute. This feature facilitates using the TT24 for both FOH and monitors. For example, the monitors are normally fed by pre-fader Aux sends. During a set change, to reset the mics for the next band, they must be muted in the monitors. This requires the pre fader Aux sends to be pre-mute.

PC AUTO FOLLOW

The TT control software can be set to operate independently from the Touchscreen or to the TT24, one from the Touchscreen and one from the PC.

6.13.1 MONITOR SOURCE

Figure 6-29 UTILITY MONITOR SOURCE

The MONITOR SOURCE Touchscreen assigns a source for the monitor outputs and the headphones. The monitor analog gain controls are located in the UTILITY area (see page 38). Choose among these sources: L/R, C/MONO, DIGITAL, TAPE/CD A, or TAPE/CD B.

The L, R, and C meters mirror the hardware meters and display the L, R, and C/M Monitor outputs. Each meter has an overload LED at the top.

The SOLO LEVEL adjusts the level of the solo group. It varies ±15 dB in 0.1 dB increments and its default level is 0 dB. The RUDE SOLO LED lights when a channel is soloed.
