13 - Rear panel & connections—Digital I/O13–3[62] 2TR RTN 1/2 switchThis switch is used to select which of the 2-trackmastering recorder inputs ([57] and [58]) is usedwhen the 2TR monitor select key [22] is active.When this switch is pressed in, the balanced XLR-type inputs are active, and when out, the unbalancedRCA inputs are active.[63] CR LEVELThis is used to control the level of the signal selectedusing the monitor select keys [22] sent through thepair of CR output jacks [61].[64] DIM key and indicatorThis switch is used to “dim” (attenuate) the level ofthe CR output by 30 dB. When the CR output isdimmed, the indicator is lit.[65] STUDIO/PHONES levelThis is used to control the level of the signal selectedusing the monitor select keys [22] sent through thepair of CR output jacks [61] and also through thePHONE jack.[66] MONO keyThis latching key puts the CR output into mono. Ithas no effect on the PHONE output or the STUDIOoutputs.[67] TB LEVEL controlThis is used to adjust the level from the talkbackmicrophone [70] before it is routed to its destina-tions.[68] STUDIO keyThis latching key is used to route the signal from thetalkback microphone [70] to the STUDIO outputs.The CR output is dimmed, and the other studio out-put is cut while the talkback is continuing.[69] PHONES jackThis stereo 1/4-inch jack is used for connecting astandard pair of headphones (40 Ω). The maximumoutput power is 50 mW + 50 mW.The headphones should be wired: tip=left,ring=right, sleeve=ground.[70] Talkback microphone (unlabeled)This microphone is used in conjunction with theSTUDIO key [68] and the SLATE and AUX 1-2 keys[24] for talkback to the in-studio talent and for tapeslating purposes.13.4Digital I/OWARNINGOnly use TASCAM-supplied and TASCAM-approved cables when making digital audioand control connections to the TM-D4000.Though the cables and connectors mayresemble computer cables, they serve differ-ent purposes, and meet a different set ofspecifications. The use of cables other thanTASCAM cables will at best cause the equip-ment to work erratically, and at worst causedamage to the equipment.If the use of cables other than TASCAMcables causes or results in damage, the war-ranty is voided.[71] DIGITAL OUTPUT (XLR-type)This XLR-type connector outputs the STEREO OUTsignal in the format selected for stereo digital output.The word length and format, along with ditheringoptions, are selected from the DIGITAL I/Oscreen (see 3.1.1, “STEREO OUT settings”).[72] DIGITAL OUTPUT (RCA)This RCA coaxial connector outputs the STEREOOUT signal in the format selected for stereo digitaloutput.The word length and format, along with ditheringoptions, are selected from the DIGITAL I/Oscreen (see 3.1.1, “STEREO OUT settings”).[73] D IN 2 (RCA)This RCA coaxial connector accepts digital audiosignals in IEC60958 format (SPDIF).This stereo signal may be routed to any combinationof the following: input channels 7-8, input channels15-16 and ST-IN 2, using the I/O SETUPscreen accessed through the DIGITAL I/O key (see3.1, “I/O setup”).Regardless of the channel assignment, the signalreceived here may always be selected for monitoringusing the D-IN 2 key of the monitor select keys [22].Using the DIGITAL I/O screens, this mayalso be used as a clock source.[74] D IN 1(XLR-type)This XLR-type connector accepts digital audio sig-nals in AES3-1992 format (AES/EBU).
