Use RCA connectors to attach a digital effects device or another S/PDIF device
to the AUX SEND 1/2and AUX RETURN 1/2digital terminals. AUX/BUS
Fader Layer faders control the AUX 1/2 SEND andRETURN. These
connections are not analog signals.
AUX SEND 3/4, 5/6
These terminals are 1/4” TRS phone plug connectors, at a level of +4dB,
10kWUNBAL. They can be used for connecting outboard signal processing
devices, or for a studio headphone feed, or as part of a multitrack output
setup. The possibilities are limited only by your imagination. The AUX/BUS
Fader Layer is the fader control for these connections. Detailed cable
connections are shown in Appendix E, Cables and Connections.
AUX RETURN 3/4, 5/6
These terminals are 1/4” TRS phone plug connectors, at a level of +4dB,
10kWUNBAL. The AUX/BUS Fader Layer is the fader control for these
feeds. See Appendix E, Cables and Connectionsfor more information.
2-Track B Input 
This is used to connect an analog source strictly for monitoring purposes, as
it does not appear as an input to the mixer. Connect a 1/4” TRS phone plug
to the output signal from a cassette deck, for example. The input signals are
sent to the 2 TR B INLED button in the monitor section. The level is +4dB,
10kWBAL.
Monitor A Out
These terminals are 1/4” TRS dual phone plugs at a level of +4dB, 600WBAL,

Format Select Switch 
This switch is used to select the signal format of the Digital Record Output,
either AES/EBU(RS-422/110½) or S/PDIF(0.5 V[p-p]/ 75½) physically. The
status information included in the output signals is always “professional”
regardless of the switch position. 
For S/PDIF usage, an optional adapter is required(Part No. DA/ADPTF). You
must make certain that the adapter connects pin #1 and #3 together.
Clock Terminating 75 ½ ON/OFF & Out / Thru Switch
Located next to the WORD CLOCK INBNC connection, this switch should
be set to 75 ½OFFand Thruposition if the DA7 is being used to pass the
wordclock signal to other devices in the chain. 
Set the switch to 75 ½ONand OUTfor terminating the wordclock, if the
DA7 is slaved and located at the end of the wordclock chain. The 75 ½ON
and OUTposition should also be selected when the DA7is being used to
slave other devices to the DA7’swordclock. See Chapter 12, D-I/O for more
information.
Clock Input
This is used to synchronize the DA7 to an external wordclock source. This
allows the DA7’s internal clock to slave to another reference, such as a digital
multi-track deck or other device. Use a BNC connector to attach an external
wordclock source.
Clock Output
This is used to slave an external device, such as a digital multi-track machine,
to the DA7internal clock. It can also be used to relay an external wordclock
that is being used to synchronize the DA7to an external device. Using a BNC
connector, other devices can synchronize to the DA7 wordclock. 
Serial Terminating Switch 
Set the switch to ON if the DA7 is the termination point of the RS-422/485
serial transmission path. The 110½switch turns this function OFF/ON.
