  • Page 2: General Description

    4420A is manufactured using certified sustainable methods. All essential parts of the loudspeaker can be recycled. The 4420A is available in black, white or 120 RAL colours on order. It is compatible with Genelec’s extensive range of mounting accessories for floor, ceiling, wall, or truss mounting.

  • Page 3: Packing Content

    4420A accepts AES67/ST2110 and Dante audio-over-IP streams. The streams are set up with Dante Controller or Dante Domain Manager software. Each 4420A supports reproduction of one or the sum of two audio input channels. The stream audio sample rate can range 32-96 kHz, with 16-24 bit resolution.

POSITIONING AND MOUNTING THE LOUDSPEAKER Place the loudspeaker so that the line of the acoustic axis points towards the main listening area. The AV install designers may indicate different aiming. Minimum clearance for amplifier cooling and reflex port function around the loudspeaker is 3 cm (13/16 in) behind, above and on both sides of the loudspeaker.

  • Page 5: Connecting Loudspeakers

    CONNECTING LOUDSPEAKERS To get started, connect an Ethernet cable from the PoE+ output in an IP switch to the 4420A Ethernet port. Use at least CAT5 cable or better. Press the power switch to power up the loudspeaker. To create a working system, you will need •...
  • Page 6 Example of powering the 4420A with a PoE+ enabled IP switch. With this method, the power budget available for all outputs connected to the IP switch must enable each 4420A to run at full PoE+ power. For 4 loudspeakers, the power supply must support 4 x PoE+ power level.
  • Page 7 There are several Power-over-Ethernet standards. The 4420A loudspeaker supports the PoE+ standard but also works with the lower power PoE standard. When the 4420A also works with lower PoE power, the duration of high SPL output is shortened, and long continuous output signals play at smaller sound level than when the PoE+ power level is used.
  • Page 8 API command or in response to IP audio stream. The power consumption in the ISS state for 4420A is 4 W. To save more power, the PoE+ power supply in the Ethernet switch or PoE injector can be turned off. However, loudspeaker wakeup will then take slightly longer time and the loudspeaker does not respond to any command on the IP network while it is not powered.

  • Page 9: Network Structure

    The 4420A can select one audio channel or a sum of two channels in a stream. The AES67 compatibility mode must turned ON to enable reception of AES67 or ST2110 streams.

  • Page 10: Analog Input

    Typically, 10 to 20 loudspeakers can be daisy-chained on one balanced line. Avoid connecting 4420A to the power amplifier outputs. If this must be done, use a balanced attenuator. Typically, an attenuation of about 20 dB is needed.

  • Page 11: Zone Settings

    GENELEC SMART IP MANAGER SOFTWARE Acoustic calibration, zone setup, input selection and loudspeaker management are done using Genelec Smart IP Manager software. This is a software intended for AV installers. Genelec recommends using the Application Programming Interface (API) inside the loudspeaker to be used with house automation systems for the end-user control.
  • Page 12 Figure 9. Controlling the zone with Smart IP Manager software. Editing acoustic settings The frequency response of the 4420A can be compensated for the room’s acoustical influences by editing the settings in the Acoustics tab in the Genelec Smart IP Manager. Acoustical calibration settings are specific to each loudspeaker.

    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.

  • Page 14: Safety Considerations

    SAFETY CONSIDERATIONS The 4420A has been designed in accordance with international safety standards. The following warnings and cautions must be observed to ensure safe operating conditions: • Servicing and adjustment may only be performed by qualified service personnel. • The loudspeaker must not be opened.

    The stated values are typical for music and speech signals. Maximum long-term output level can be further limited by loudspeaker system protection. Genelec recommends using PoE+ whenever possible. Using lower-power PoE can limit short-term maximum and long-term maximum, depending on the characteristics of the signal being reproduced.
