DB25 Wiring

Apollo x8p’s line inputs and outputs can be accessed via 25-pin D-sub female
connectors. Each DB25 jack carries eight balanced line-level audio channels on the
standardized Tascam pinouts also used with Digidesign and Avid products.

DB25 Connector Pin Numbers

The pin numbers for female DB25 connectors are shown in the diagram below. When
facing the Apollo x8p rear panel, pin 1 is the upper rightmost pin.
