Aux1 And Aux2 Inputs; Emergency Input; Line Out; Pre-Out / Power In Connections - Optimus AXD-30 Operating Instruction

6.4. AUX1 and AUX2 inputs

These are asymmetric inputs through RCA connectors.
They have a sensitivity that can be adjusted by means of a rear
potentiometer (from -10dB to 0dB)
For their connection, see Figure 12.

6.5. EMERGENCY input

This is an asymmetric input through a RJ45 connector, with a
sensitivity of 0dB.
Pin number 3 of the emergency connector supplies a voltage of 24V
DC (maximum 100mA) which can be used to supply low
consumption devices (MD-94, MD-94R consoles...)
It has a speech preference contact which is activated by joining pin
no. 6 with pin no. 8 of the connector, while it supplies 24V DC
(maximum 100mA) through the RELAY ACT strip.
This input has priority over any other input of the amplifier.
It does not have a volume control. The output level of the
emergency signal will always be at maximum volume.
It is especially suitable for receiving emergency announcements,
which take priority over any other signal (e.g. evacuation
messages).
Cable STP of Cat 5 must be used for its connection (see Figure 13).

6.6. LINE OUT

This is an asymmetric preview output through a male XLR
connector, with a sensitivity of 0dB.
For its connection, see Figure 14.

6.7. PRE-OUT / POWER IN Connections

PRE-OUT: Preview output.
This is an asymmetric output
through an RCA connector,
with a sensitivity of 0dB.
POWER-IN: Input towards the
power phase. This is
asymmetric input through an
RCA connector, with
sensitivity of 0dB.
They are used to install a unit
(equaliser, antilarsen...)
between the preview and the
power phase of the amplifier
(see Figure 15).
If they are not used, they must
have the interconnection
jumper positioned between
them.
