SECTION 4 OPERATING INSTRUCTIONS
For the external modulation input, you can select either DC coupling or AC coupling by following the procedure
detailed below:
(1) Press the "Src" [F4] key in the Modulation menu to open
the "Audio Source" menu.
(2) Select coupling display for Ext1 or Ext2 by operating
the "↓" [F2], "↑" [F3], and "→" [F4] keys (the characters

Applying a signal at a voltage higher than ±10 V to the "Ext1" or "Ext2" connector could result in breakdown
