a)
Spare Channels Input
The equipment has 8 input back-up amplifier channels
per each internal amplifier. Each connection has two
ter and – where the redundant amplifier output
will be connected. The redundant amplifier must be a
100V line public address amplifier with a minimum
power equal to the nominal channel amplification
power of the equipment. For more information about
the connection of back-up amplifier, see chapter 4.5
The connection is made with a 2-pin female euroblock
connector and pitch 5.08 mm (supplied with the unit).
The wire size range for each pole of this connector is:
0.5
→
2.5 mm2 (22
→
12 AWG).

Speaker Line Output
The equipment has between 4 and 8 amplification channels, each channel has two
speaker line outputs marked as A and B. The rated power of the amplifier channel is
divided between both output lines. For more information about the connection of the
speaker lines see chapter 4.6. Each line connection has two + and - terminals for
connecting speakers to 100V or low-impedance depending on the model.
