234A Operating Manual Genelec 1234A Smart Active Monitor
Genelec 1234A Operating Manual Introduction Congratulations and thank you for choosing Genelec! Since 1978, Genelec has been guided by a single idea – to make perfect active monitors that deliver neutral and accurate sound in every kind of acoustical environment. In Genelec’s quest for this ultimate goal, our unrivalled commitment to research and development has led us to continuously develop innovative driver technology, electronic circuitry, enclosure designs and more.
890 mm The monitor enclosure has its acoustical axis midway between the midrange and treble drivers. This axis should be used as the listening and measuring axis of the system. (See Figure 1 and 2). The typical listening distance varies between 2 and 3.5 m (6½ and 11½ ft) from the monitors. The monitor should be aimed so that the vertical acoustical axes of the two monitors meet midway between the standing and seated listening position (1.4 m – 4 ft 7 in from the floor).
inferior frequency response and stereo image. Ensure that the enclosure is flush with the surface of the wall. If a decorative cloth frame is used to cover the wall, make sure that the edges adjacent to the monitor are less than 20 mm (3/4 in) deep. The cloth must be very thin Tricot or acoustically transparent material, otherwise the high frequency response of the system will be adversely affected. Genelec approved cloth grilles are available.
