Interface Features
• 1 Megahertz RS-422 Mac serial interface.
• A dual 1 In/3 Out MIDI interface (2 MIDI Ins and 6 MIDI Outs - sup-
porting 32 MIDI channels in all). One of the MIDI interface channels
is connected to the modem port and the other to the printer port.
• One MIDI Out (modem port) and MIDI In (modem port) are into the
front of the Mac Syncman making it easy to plug in your master key-
board.
• Selectable MIDI routing. Mac Syncman can be set up as a 1 In/6 Out
or as a dual 2 In/3 Out MIDI interface.
• Serial Thru /MIDI switches. With these switches the Mac Syncman
MIDI interface can be bypassed, to go to the printer or modem, with-
out having to re-plug serial cables.
• MIDI In and Out indicator LED’s for both MIDI interface channels.
These indicators blink whenever MIDI is sent or received.
Note: These indicators work only if the Mac Syncman’s two left Serial
Thru/MIDI switches are in - enabling MIDI.
Sync Features
• Reads and writes with high reliability to most reasonable quality tape
recorders and media.
• Generates and reads all SMPTE formats including 24, 25, 30 and Drop
Frame. SMPTE Formats can be selected from dip-switches on the
front of Mac Syncman.
• Can generate a SMPTE stripe manually (with 0 offset), or remotely
with specified offset upon receipt of a MIDI Time Code Offset mes-
sage. This message can be sent from your sequencer or from an
appropriate DA.
• Converts SMPTE to either MIDI Time Code or Direct Time Lock (for
older versions of Performer).
• Built-in reshaper allows you to duplicate recorded SMPTE sync
stripes.
• When reading a sync stripe from tape a special Tape indicator LED
shows when sync is obtained or lost.
• Built-in automatic “Jam” Sync allows Mac Syncman to re-cover from
most normally encountered tape drop-outs.
• Built-in SMPTE regenerator. The Mac Syncman has a dedicated, high
quality regenerator which can be used to repair even badly damaged
