The 1234AC is a smart main studio monitor for use in demanding film and post production work, where perf screen or hi-res LED displays are employed.
Make accurate decisions
Designed for mixing stages and large control rooms, the directivity and SPL capability of the 1234AC is compatible with typical screen channels in commercial cinema, but with the higher performance required for professional monitoring. The 1234AC may be used in either horizontal or vertical orientation - thereby tailoring the LF directivity to both the room and the monitor placement - while precise on and off axis imaging allows you to make accurate mix decisions even when sitting outside the narrow sweet spot of most studio monitors.
Optimise for your room
The 1234AC tightly integrates with our GLM calibration application, which compensates for detrimental room influence, perf screen effects and delay, regardless of whether you work with traditional or large immersive formats. GLM also builds complete monitoring systems, so that the 1234AC can easily be combined with other types of Genelec smart monitors and subwoofers to deliver truly optimised reference monitoring - and material that translates perfectly.

Group delay
The latency at high frequencies from the input to the acoustic output, measured in the analog input:
Extended Phase Linearity in GLM set to OFF
5.2 ms
In Genelec performance graphics, the time of converting the from an electronic input signal to the acoustic output in a Genelec monitor is described by two factors – latency and group delay. The group delay factor can be read in the graphics for a specific frequency. The total frequency-specific input-to-output delay is a sum of the latency and group delay factors. To understand the significance of this total delay, consider that moving a loudspeaker away by 1 meter creates an additional delay of about 3 ms.
