Connecting the Outputs
Connecting the Loudspeaker Outputs
The power amplifier is supplied with outputs for 4 model XCA 1500 and XCA 2000
speakers or for 2 model XCA 1000 and XCA 1002 speakers.
Each of the 2 loudspeaker outputs can also be used in the mono-bridge mode. In
fact, only one loudspeaker is powered in this mode, but the available output voltage
is higher.
Moreover, one cinch output remains for triggering other system components.
The loudspeakers must be connected with double wires. Insulate
The loudspeakers must be connected with double wires. Insulate
the naked wire at connecting terminals. Make sure that there are no
harp edges which may damage the cables.
Only use loudspeakers which have a sufficiently high loading capa-
city (see „Technical Data“).
Make sure that the loudspeakers have been connected in the cor-
rect polarity, i.e. plus and minus signs harmonize!
The connection cables of the loudspeakers are normally coded:
Some loudspeaker manufacturers indicate the (+) wire by means of
an additional colour stripe, others use a corrugated cable for the (+)
terminal and a smooth one for the (-) terminal.
This amplifier has been designed for a loudspeaker impedance of at
least 2 ohms (stereo mode) or 4 ohms (mono-bridge mode). Never
connect loudspeakers with a lower impedance.
Depending on the model and mode of operation, connect the loudspeaker outputs
according to the following schemes. Observe the minimum impedance given for the
corresponding mode of operation.
