Inter-M PAC-5000 - Manual (Page 13)

DIGITAL PA COMBINATION SYSTEM
11 PAC-5000
- Normal broadcast state: It outputs the corresponding broadcast to HOT terminal only.
- EM and fire broadcast state: It outputs the corresponding broadcast to HOT and EM terminals in all.
- If it is under emergency broadcasting causing by the fire contacting point input, it outputs the
corresponding broadcast at a predefined level independent of a main sound volume position.
2) Wiring method for the speakers
- When wiring the speakers, separate the power cable from a wall outlet and then select proper terminals
according to speaker kinds and connecting methods that you want to use.
3) Rated output and impedance
※ Caution : Pay attention a total impedance of speaker terminals does not lower than the rated (Refer to
Table above.) in any cases.
4. AMP OUTPUT / INPUT TERMINAL
Preparing for an area where the output(120W+120W) of the internal amplifier is deficient, the output and
input terminals were built in the rear part to run external amplifiers with a higher output.
※ The input terminals and the output terminals must be mutually connected to run the internal amplifiers.
1) AMP output terminal
- It is the output terminal of the internal amplifier which is connected to AMP IN terminal.
- Pay attention to Group A,B and polarities(H,C) when connecting them.
2) AMP input terminal
- It is the input terminal connecting the amplifier output which is connected to the output(AMP OUT)
terminal of the internal amplifier or the output of an external amplifier. An input connected to it can be
transmitted to an area you want passing through the speaker ZONE selection button in the front part.
Contents A Group (12 Zone) B Group (12 Zone)
EC & Associated, JAPAN Version 100V/83 Ω (120W) 100V/83 Ω (120W)
USA/CANADA & Associated Version 70V/42 Ω (120W) 70V/42 Ω (120W)
Installing method for high impedance speaker (Same as the HOT/EM terminal)
※ When high impedance speakers are connected in parallel in each of the areas, you can wire
them up to 120W of a total summation from the all areas.
※ Caution when wiring zone output (1~24)
Wire them by the limitation that an output sum of 12 zones in each of Group A or B does not
exceed the rated output (120W+120W).
