AXF-240
AMPLIFIER

5.6. LINE OUT

The unit includes a balanced audio line output though XLR connection. This
output broadcasts the audio of the whole system, general and priority inputs,
and it is not affected by Master, Bass and Treble volume controls.

5.7. PRE OUT / AMP IN CONNECTION

PRE-OUT: Preamplifier output. This is an unbalanced output through an RCA connector, with a
sensitivity of 0 dB.
POWER-IN: Input towards the power stage. This is an unbalanced input through an RCA connector,
with a sensitivity of 0 dB.
They are used to install an external unit (equaliser, feedback suppressor...) between the
preamplifier and the power stage of the amplifier (see next Figure).
If this connection is not used, the bridge between PRE OUT and AMP IN must not be removed.
