AUDIO OUTPUTS “REC” “A” AND“B”. Outputs (unbalanced, with RCA connectors) for
connecting a recording device (or other device).
Note:
the signal level is not regulated by the main outputs’ volume controls.
HIGH-LEVEL (“LINE”) AUDIO INPUTS 6÷9. Double-line inputs (RCA connectors for
stereo music sources) with -10dBu (245 mV) sensitivity. The right and left channels are
combined, resulting in a single mono signal that can be directed to one or both the audio
outputs.
MICROPHONE AUDIO INPUTS 6÷9. Balanced audio inputs for microphones (XLR
connectors).
AUDIO INPUTS 2÷5. Balanced audio inputs (XLR connectors). The “MIC / LINE” level
can be selected with the relative switches on the front panel.
SINGLE MICROPHONE AUDIO INPUT FOR ANNOUNCEMENTS; CONTROLS. Balanced
audio input (XLR connector) for announcement microphone, with terminal board having
the following commands:
- CHIME: if grounded, activates the warning signals;
- PRIORITY: if grounded, gives absolute priority to input 1;
- GROUND: earth; - VDC LED: feed output for an LED.

To avoid inductive phenomena that might give rise to hum or other disturbances and
compromise the equipment’s proper functioning, the connection cables that carry the audio
signals must not be near:
1) equipment that produces strong magnetic fields (large power-supply transformers, for
example);
2) electric-energy conductors;
3) lines that feed diffusers.
CONNECTIONS
- Do not set up the equipment in places subject to high-intensity vibrations or particularly
exposed to dust or humidity.
- The container rack must conform to the EN 60439-1 standard; in particular, the back must
be closed with appropriate panels.
INSTALLATION
WARNING:
When the equipment is fed with direct current, do not disconnect the
powersupply cord. This is in order to keep the equipment grounded. The equipment is not
equipped with a device for recharging batteries. An appropriate device should therefore be
considered.
