Loudspeaker terminals
The PA 2500 R is equipped with two pairs of loudspeaker terminals. The
terminals are plated with a layer of highly conductive, corrosion-resistant
rhodium in order to ensure excellent electrical contact with minimum transfer
resistance.
Always use high-quality loudspeaker cable with forked speaker lugs to connect
your loudspeakers.
Bi-Wiring
The two pairs of terminals are ideally suited for use in the bi-wiring arrangement
in conjunction with high-quality loudspeakers. For bi-wiring mode connect the
bass range to output A, and the mid-range / treble range to output B (see wiring
diagram).
Dual-zone mode
Alternatively two pairs of speakers can be connected to the machine (dual-zone
mode). The impedance of each speaker must not be lower than 4  (DIN
rating).

The speaker outlets A and B can be switched optionally together (Bi-Wiring) or
separately (Dual-Zone). (see. chap. 'Basic settings of the PA 2500 R')

Caution!
The load capacity of the loudspeakers connected to the device must be
appropriate to the amplifier. The speaker impedance must be at least 4 Ohm
(DIN rating). Always connect your loudspeakers using ready-made,
purpose-designed speaker cables terminating in approved connectors. The
speaker cables and connectors must be insulated in accordance with
regulations, and the conductors must have a minimum cross-sectional area
of 1.5 mm².Make sure that the terminals are firmly screwed down, and that
no short-circuits are possible.
Interface for diagnosis work and computer-controlled operation of device
functions. (Home-Automations-Systems e. g. CRESTRON, AMX).
The PA 2500 R can be turned on and off by means of a switching voltage (+5
... +20 Volt) connected to this socket. If the trigger function is used to switch the
PA 2500 R on, it is automatically set to the source previously selected in the
menu (see chapter entitled 'Basic settings of the PA 2500 R').
Connector assignment (3.5 mm jack plug)

The Trigger function can be switched on and off in the Amplifier menu.
(See chapter entitled 'Basic settings of the PA 2500 R')
Control output for  devices with R2

One of the two sockets can be used as a trigger input. An adapter lead is
required for this; please refer to the  accessory range.
