(35) DB25 Line Inputs 1 – 8
The line inputs can be accessed via this female DB25 connector. The single DB25 jack 
carries eight balanced line-level channel inputs using standardized Tascam wiring. 
Note: For connector pinouts, see DB25 Wiring.
The DB25 line inputs are normalled to the TRS combo jacks. If a DB25 line input is 
active and a 1/4” cable is plugged into the same channel’s combo jack input, the DB25 
input is disconnected and the combo jack input is used instead.
Important: To use a DB25 line input, the channel’s input must be set to LINE and 
its ¼” connector (including Hi-Z input) must not be connected.
(36) Mic/Line Combo Inputs 1 – 8
XLR plugs are routed to the channel’s microphone input, and TRS plugs are routed to the 
channel’s line input. 
Combo jack inputs 1 – 8 are switched between the XLR and Line connections using the 
front panel Input switch (#6) or the Console application.
XLR Mic Inputs 1 – 8
The combo jack balanced Microphone inputs accept XLR plugs. Pin 2 is wired positive 
(hot).
+48V phantom power is available for the XLR inputs via the front panel switch (#6) or 
the Console application.
Caution: To avoid potential equipment damage, disable +48V phantom power on 
the channel before connecting or disconnecting its XLR input.
¼” Line Inputs 1 – 8
The combo jack line inputs 1 – 8 accept balanced ¼” TRS phone plugs. Unbalanced ¼” 
TS plugs can also be used.
