Universal Audio Arrow Manual page 191

• When a Unison plug-in is removed from the Unison insert, Arrow's mic input
impedance reverts to its default value of 5.4K Ohms.
• Arrow's hardware preamp controls remain active even if the Unison plug-in is
disabled.
• When the original hardware preamp being emulated by the Unison plug-in
has a Hi-Z (instrument) input and associated Hi-Z input switch, this switch is
unavailable in the Unison plug-in interface. Instead, the Unison plug-in's Hi-Z
input is automatically selected when a mono (tip-sleeve) plug is inserted into the
Unison channel's front panel Hi-Z input jack.
• A microphone, line input, or Hi-Z instrument source must be attached to the
Arrow input channel for Unison plug-in processing in the Unison insert to be
audible.
