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 amplifi er.
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
power phase. This is an asymmetric
input through an RCA connector, with
a sensitivity of 0dB.
They are used to install a unit
(equaliser, antilarsen...) between the
preview and the power phase of the
amplifi er (see Figure 15).
If they are not used, they must
have the interconnection
positioned between them.
