CONNECTING THE OX8
OX8 Inputs
You can connect mics and direct boxes to the OX8 using the front panel XLR inputs, or the rear panel DB-25 and Euroblocks terminals.
Which input you choose to use will depend where the OX8 is located and what you are connecting to it. For instance, individual micro-
phones may be connected directly via the front panel XLRs , or a multi-channel snake may be used to connect to the DB-25 inputs
. Finally, a wall-mounted panel of XLRs may be connected to the Euroblock inputs with a multi-channel snake cable .
Connecting the Euroblock Terminals
Euroblock, or European style terminal blocks, also called Phoenix blocks, are removable screw terminal connectors. The Euroblock
connector requires no soldering to terminate. Instead, the wire is stripped, inserted into slots in the connector and locked into place
with a standard screwdriver. The connector then mates with the socket. Pin termination for the Euroblock terminals are clearly marked
on the rear panel.

Connecting the DB-25 I/O
The DB-25 connectors on the rear panel use the TASCAM pin-out standard for analog audio. Connecting the OX8 to devices equipped
with DB-25 connectors like digital multi-track recorders and mic preamps is simply a matter of using compatible DB-25 audio cables.
Radial balanced DB-25 cables are a perfect match for the OX8 and can be ordered in standard or custom lengths.
The pin-out diagram is silk-screened on the rear panel for reference and represents the panel-mount female pin-out. To make your
own interface DB-25 cables follow the pin-outs below for male and female connectors.
