1 Lineout and Preamp audio outputs — Connect an audio output device to
either connector for line level audio outputs. The Lineout and Preamp audio
outputs are simultaneously active. Therefore, two devices can be connected at
the same time (one to each output).
• The Lineout connector outputs a fixed level audio signal that is not
affected by the audio adjustments listed in the table below. A tape
recorder or assistive listening device would typically be connected here.
• The Preamp connector outputs a variable, line level audio signal for use
with a powered amplifier. The volume can be controlled (attenuated)
via the front panel knob, RS-232, or Ethernet/IP communication. The
volume range is 0 (mute) through 40 steps (0% through 100% of the
maximum volume).

* Lineout is not affected by any of the adjustments listed above.
After the audio inputs and outputs are connected, see chapter four for
instructions on how to adjust the per-input and preamp audio levels.
Lineout and Preamp outputs can both be wired as unbalanced or balanced
(see diagram). Only the Preamp output has the -10 dBV/+4 dBu options.
• Unbalanced, -10 dBV (-8 dBu, 320 mVrms) — the default, for consumer
level devices such as VCRs, DVD players, and stereo receivers
• Balanced, +4 dBu (+6 dBV, 1.23 Vrms) — for professional devices such as
mixers, signal processors, and power amps
