Input set for 2 AUX sources connections ( FM/AM Tuner, CD player etc..) through RCA input or Eurobloc
removibile terminal
Dip-switch:
PIN1 pos. ON = input AUX2 active
pos. OFF =input AUX1 active
PIN2 pos. ON = no attenuation for both AUX inputs
pos OFF = AUX input selected is 10 dB attenuated
PIN3 pos ON = high pass filter active in input
pos OFF = no pass filter active in input
PIN4 pos ON = input sensibility set at -10dbV
Pos OFF = input sensibility set at a 0dbu
6. Input AMP IN – OUTPUT PRE OUT
Standard configuration MAIN IN input is connected to
PRE OUT output throughout a bridge.
It is possible to optimize the amplifier signal setting an
external unit ( so as un equalizer processor, etc..)
between the two terminals .
For connections revert to the following fig.
7. TAPE OUT output
8. AM Antenna or loop input
9. FM Antenna input
10. Priority functions activation terminal
When PRIORITY and COM terminal are short circuited, INPUT2 INPUT3, INPUT4 e INPUT5 are
automatically attenuated for the signal present in INPUT1 Priority status.
11. SIREN TERMINAL
A tone chime with priority on all signals is generated when the two terminals are short circuited. Siren
volume level can be set from MASTER control
12. TEL.PAGING Input
Set to receive a high level telephone central audio signal (600
Ω)
( balanced or unbalance) . The signal level is set through GAIN trimmer.
The fixed and EUROBLOC removal terminals are then in parallel .
13. Loudspeaker output line terminal
These Terminals are used for 4Ω, 8Ω, 16Ω, 50 V, 70 V and 100 V loudspeakers connection
14. Grounding Screw
When there is no grounding on the power socket, such screw allows grounding connection of the
mechanical unit parts .
Attention.
Grounding Screw connection must be done by qualified person.
15. Gain
Sets the gain of the TEL input
16. Priorità Priority on Input 1
Remove the metal jumper to release priority function from input 1
Note: even when the jumper is in place, Input 1 does not have priority on the TEL PAGING input.
