Several mounting options are available for each loudspeaker model. See Genelec Accessories
Catalogue on

for a complete list of mounting hardware options. The accessories
can come with instructions on the proper methods of installation.
4.3 Connection Analog Input
Before cabling, turn off the power in all loudspeakers.
An analogue audio input is provided using a screw-mount Euroblock connector. This enables easy
connectivity and daisy-chaining the balanced audio signal to several loudspeakers. When you
daisy-chain loudspeakers, connect a second signal cable to the plug (Figure 6).
The input impedance of the analogue input is 10 kOhm. The pin sequence of the connector is
shown in Figure 6. The number of loudspeakers that can be on the same daisy chain is set by the
capability of the source device analogue output. The daisy-chained loudspeakers appear
electrically in parallel, reducing the load impedance presented to the source device. Typically, 10 to
20 loudspeakers can be daisy-chained on one balanced line.
If there is a need to connect the analogue input of the speaker to the same circuit as a passive
loudspeaker system, please connect the Smart IP loudspeakers analogue input in parallel with the
amplifiers analogue input.
Avoid connecting Smart IP loudspeakers to the power amplifier outputs. If this must be done, use a
balanced attenuator. Typically, an attenuation of about 20 dB is needed. Beware that some power
amplifiers can provide a signal that exceeds the maximum voltage at the analogue input, and this
can result in failure of the analogue input.
