[. . . ] Install in accordance with the manufacturer's instructions. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat. Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades with one wider than the other. [. . . ] 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. 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 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 -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. 46 Mackie TT24 Digital Live Console Owner's Manual Rear Panel Connectors 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 18. However, when the MATRIX mixer is active, each output can provide a separate mix of virtually any input source. See Matrix Mix on page 87 for details.

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 AC, Expansion OUTPUTS AC) for channels 1324 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. 48 Mackie TT24 Digital Live Console Owner's Manual Rear Panel Connectors Table 4-1 ADAT Digital I/O Channels at 44. 1/48 and 88. 2, /96 kHz Sample Rates 44. 1/48 kHz INPUT A INPUT B INPUT C OUTPUT A OUTPUT B OUTPUT C Expansion INPUT A Expansion INPUT B Expansion INPUT C Expansion OUTPUT A Expansion OUTPUT B Expansion OUTPUT C 18 916 1724 18 916 1724 N/A N/A N/A N/A N/A N/A 88. 2/96 kHz 14 58 912 14 58 912 1316 1720 2124 1316 1720 2124 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.
