When active, the indicatorbeside and above the key lights, and the commandkeys take on their shifted functions, as indicated bythe blue captions above them.See 4, "SHIFT functions" for details of these shiftedfunctions.2.5 Rear panel[32] DIGITAL (AES/EBU) INPUT/OUTPUTThese XLR-type connectors conform to the AES/EBU3-1992 standard and are used to accept(INPUT) and transmit (OUTPUT) digital audio datain that format. The INPUT connector can alsoreceive balanced IEC60958 format (SPDIF) data.The format of data received (AES/EBU or SPDIF) isautomatically detected.[33] DIGITAL (COAXIAL) INPUT/OUTPUTThese RCA connectors conform to the IEC60958standard (SPDIF), and are used to accept (INPUT)and transmit (OUTPUT) digital audio data in thatstandard. The INPUT connector can also receiveunbalanced AES/EBU3-1992 format data. The for-mat of data received (AES/EBU or SPDIF) is auto-matically detected.[34] CONTROL I/OThis 15-pin ’D’-sub connector is used for connectionto a suitably-equipped controller.As well as the mode described in the table below, thisconnector can also be used as a serial connector.Please contact your TASCAM distributor for detailsof this facility.The pinouts of this connector are given below:[35] REMOTE INThis 3.5 mm jack is used to connect the optional RC-D45 remote control unit.Do not use this jack to connect any remote controlunit other than one designed especially for use withthe tape deck.[36] Power cordMake sure that the power supply voltage matches thevoltage requirements of the tape deck as marked onthe rear panel. If there is any doubt, consult yourTASCAM dealer.[37] (BALANCED) ANALOG INPUTSThese female XLR connectors provide balancedinputs at a nominal +4 dBu level. The wiring of theseconnectors is:1 = ground, 2 = hot, 3 = cold. The nom-inal impedance of these connectors is greater than25 kΩ.[38] (UNBALANCED) ANALOG INPUTSThese RCA connectors provide unbalanced inputs ata nominal –10 dBV level. The nominal impedance ofthese connectors is greater than 50 kΩ.[39] (UNBALANCED) ANALOG OUTPUTSThese RCA connectors provide unbalanced outputsat a nominal –10 dBV level. The nominal impedanceof these connectors is less than 1 kΩ.Pinnumber SignalDirectionFunction1 STOP IN External com-mand reception;active when low(at ground poten-tial for 30 ms ormore)2 FWD PLAY IN3 F.FWD IN4 REW IN5 PAUSE IN6 REC PLAY IN7 SERIAL IN8 Ground — —9 FWD PLAYTALLYOUT Transmit trans-port status indica-tion signals inopen collector(maximum allow-able voltage 15 Vand maximumallowable current80 mA)10 F.FWD TALLY OUT11 REW TALLY OUT12 STOP TALLY OUT13 REC/PLAYTALLYOUT14 PAUSE TALLY OUT15 TAPE ENDTALLYaOUTa.
