ACD1
■ When using a Tn series or PC-N series amplifi er
ACD1 (REAR PANEL)
Connect the DATA PORT terminal of the ACD1 to the DATA PORT terminal of the compatible amplifi er with a LAN cable.
• Communication check
Check that the REMOTE LED of the compatible amplifi er lights up when the ACD1 and compatible amplifi er are connected.
■ Internal data
Check that the project data is stored with the system mode during normal use using the Amp Editor.
If repair has been made, start the Amp Editor after restoring the original connection, and select "Amp Editor → Device" in the
Sync Direction screen to restore the internal data.
If the ACD1 is not connected, the data will be judged as different internal data (not original data).
* If an error indication of "Amp f/ware old" is shown, it is necessary to replace the IN circuit board of the amplifi er and
upgrade the fi rmware of the amplifi er. (BU 1405)
