Figure 10. Modifying the acoustic settings of Smart IP loudspeaker.
Factory settings
The factory setting for all acoustic settings is “OFF”, sensitivity attenuator set to 0
dB, and delay set to 0 ms. These give a flat anechoic response. Both the audio-
over-IP stream and analogue inputs are selected to play. Audio stream settings
are reset. With the factory settings, all that is needed to play audio is to provide a
signal to the analogue input or to configure an audio-over-IP stream in the stream
input. Set stream again to resume normal streaming operation.
To reset 4420A to factory settings, press the power button for more than 10
seconds. The loudspeaker indicates that the reset process starts. Then, you can
release the power button but do not disconnect power supplied by the Ethernet
cable until the reset process is complete. Once the reset is complete, the
loudspeaker again becomes available and active on the Smart IP Manager
software. This typically takes less than one minute.
APPLICATION PROGRAMMING INTERFACE (API)
4420A Smart IP loudspeaker has a set of API commands that can be used to
enable control of 4420A using a house automation system or similar IP network
connected device. The document describing the API command and how to use
them is available from Genelec. Please visit www.genelec.com.
MAINTENANCE
There are no user-serviceable parts in the loudspeaker. Maintenance or repair of
the 4420A must only be done by Genelec authorised service personnel. This is
particularly important to maintain.

‘sensitivity’ as
needed.
Click on a filter
button, select ‘filter
type’ and adjust
parameters.
