  • Page 20 Connection The 3400-Orator II system can be interconnected via one or two loop circuits. The first loop circuit called the 3400-loop is controlled by the Gent 3400 fire panel, where one or more DAUs are connected to the loop. The second loop circuit is the audio loop connected to the master ACU .

    Because of the narrow beams it is important to carefully align the loudspeakers. If repeater units are used for example to cover a long church the loudspeakers should be adequately spaced (12 to 15 metres) or use signal delay lines. System 3400 Orator II Application 13499-36 Issue 1_7/97...

  • Page 41: Loudspeaker Cable Losses

    Loudspeaker cable losses Cable power loss Loudspeaker cable losses Where appropriate refer to designers notes, cable types, amplifier module. Cable power loss Having identified the amplifier zonal requirements the cable power loss must be considered. This is ensure that power can be distributed effectively along the cable length and an allowance is made any power loss.
  • Page 42 Cable power loss Loudspeaker cable losses NOTE: There are some PA companies that allow for power losses of up to 3dB at the end-of-line. This effectively lets the drive voltage drop from 100V to 70V. This however is not good practice as only half of the amplifiers power can be used to drive the loudspeakers.
