The sensitivity of the tranformer-balanced
floating input is +6 dBu (1.55 V). The three-
pin female XLR jack is wired in the standard
manner (pin 1 = ground, pin 2 = +, pin 3 = -).
If you are connecting unbalanced analog
sources, you will need to solder a bridge
between pins 1 and 3:
In digital mode, this same XLR input accepts
the digital signal according to the AES/EBU
specification (110 Ohm balanced).

This digital input, configured as a 75-Ohm
BNC connector, is intended to receive signal
sources in S/P-DIF or AES 3id format. The
incoming digital signal line requires one

75 -Ohm terminator at the very end, as the
O 300 D has no internal termination.
The XLR input and the BNC input are wired
in parallel across a transformer. The fact that
the termination is wired externally allows you
to make connections in a wide variety of
ways:

To obtain an output voltage of 1 Vpp at the
BNC-output connector (with 75 - Ohm
terminator), an input voltage of 5 Vpp at the
AES/EBU input is required. This complies with
the rules for AES/EBU level. If the input level
varies, the output level does so accordingly.
