Connections
1. BAL input
Use this XLR balanced input for connection to balanced-
output preamps of other brands. To select this input, set
the input switch to BAL (left position). To remove the XLR
plug, push on the tab above the jack and pull the plug out.
2. Direct input
Use this XLR balanced input only for connection to the
Constellation Audio Virgo or Altair preamp. This connection
forms the Constellation Direct—an audio interface that is,
in essence, perfectly balanced. The positive- and negative-
going halves of the signal will exhibit near-zero difference
except for their polarity. To select this input, set the input

switch to Direct (middle position). To remove the XLR plug,
push on the tab above the jack and pull the plug out.
3. RCA input
This input is provided as a convenience. You can use it if
you elect to feed the amplifier with an unbalanced signal
source. To select this input, set the input switch to RCA.
However, to get the best performance from the Hercules II
you must use an XLR input.
