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

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

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 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).

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.

3.1.9 SOLO

Press the SOLO button to solo the channel. This yellow backlit button lights when the channel is soloed. The PFL/AFL global selection is done in the Solo master section (see

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 button to select the ANALOG bank. The button lights red and the 24 analog mic/line inputs are assigned to channel 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 assigned 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 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

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.
