NOTE. The male XLR connectors of instruments equipped with
Option 02 (Analog Line Output) are labeled ANALOG OUT; these
instruments do not have provision for loop-through on the balanced
XLR connectors.
The balanced XLR inputs of Option 02 instruments are unterminated
when the associated TERM switches are set to EXT. To avoid signal
degradation, always leave the TERM switches of Option 02 instru-
ments set to 110
Ω.
Refer to Appendix C: Options for more information about Option 02.
H 75 Ω BNC connectors that accept unbalanced, digital audio signals
in both professional (AES/EBU) and consumer (IEC958) formats.
These inputs have no provision for internal termination; if the 764
is placed at the end of a signal path, install a 75
Ω end-line
termination (Tektronix part number 011-0102-00) on the unused
loop-through connector.
An RCA phono plug-to-BNC male cable or adapter may be
required to input consumer digital audio. Plug is available in North
America through Markertek Video Supply,
