INSERT I/O (1 to 8) are unbalanced phone jack connectors. Both
the nominal output and input levels are +0 dB. Wiring is
sleeve–ground, tip–out, and ring–in. Connect external dynamic
processors and other analog devices here.
9. POWER switch
This is a push-type power switch. It is recessed to prevent
accidental operation. Press once to power ON; press again to
power OFF.
10. METER connector
This 15-pin Dsub connector sends the meter information from each
of the input channels, tape and effect return channels, auxiliary
channels, etc., to the optional meter bridge (MB02).
11. TIME CODE INPUT
SMPTE connector
This phone jack is a nominal –10 dB/10k connector. It accepts
standard SMPTE timecode to synchronize the 02R to an external
timecode source.
MTC connector
This is a standard 5-pin DIN-type MIDI connector. It is used to
connect the 02R to a MIDI timecode source for external
synchronization.
12. STEREO OUT DIGITAL connectors
The COAXIAL output is an RCA/phono jack. It outputs the main
stereo signals for recording, and can be connected to DAT, MD,
and DCC digital recorders via a 75 coaxial cable. The output
format is IEC958 Part 2 (S/PDIF - Consumer).
The AES/EBU output is an XLR-3-32 type connector. It also
outputs the main stereo signals for recording. The output format is
IEC958 Part 3 (AES/EBU - Professional).
13. MIDI connectors
These are standard 5-pin DIN-type MIDI THRU, OUT, and IN
connections. They are used to connect the 02R to external MIDI
devices for sequencer synchronization and control.
14. WORD CLOCK connectors
These are TTL/75 BNC connectors for transmitting (OUT) and
receiving (IN) word clock signals. A switch is provided to apply a
75 terminator to the signal if the 02R is the last device in the
chain.
15. TO HOST connector
This 8-pin Mini DIN connector is to plug a Macintosh or PC into
the 02R for dedicated external system control.
