These unbalanced inputs are provided as a convenience for use with unbalanced signal sources.

Whenever possible, we recommend using XLR connections instead. Connecting to an unbalanced source

is handled in the same way an XLR balanced source.

The input numbers from left to right, looking at the back of the Altair II are:

IMPORTANT NOTE: To preserve true dual-mono operation, the Altair II uses a symmetrical circuit

layout. This configuration requires that the Altair II's back panel connections be laid out a little

differently from those on most preamps. For example, the left-channel connection for Input 5 is at the

far right side of the back panel, and the right-channel connection is at the far left side. Connecting the

cables in the usual side-by-side fashion will result in an incorrect installation and the mixing of sounds

from different source devices.

3. XLR outputs

The inner six XLR connections on the rear of the Altair II are outputs. The signal at these outputs is the

same—it does not matter if you use output 1 or output 2. To remove an XLR plug, push on the tab on

the connector body and pull the plug out.

From left to right, looking at the back of the Altair II, the outputs are: 1

, 2

Be sure to match the output to the correct channel on your amp. As you are looking at the back of the

Altair II, the outputs on the left side are for the right channel, the outputs on the right are for the left

channel.

When XLR connections are used to connect the Altair II preamp with the Centaur or Hercules

amplifiers, the Constellation Link is created—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.
