The 1235A brings the sound and heritage of the iconic 1035 into the modern recording age. High SPL capability and precise imaging come together in a main monitor that adapts to your room.
Classic heritage
The original 1035 became the hallmark of prestigious studios around the world who demanded a wall-mountable full-range monitor that could deliver true reference performance at high SPLs and over long listening distances. Now, with 96 kHz processing and all the power of our Smart Active Monitoring technology, the 1235A is available both complete or as a retro-fittable upgrade kit for owners of 1035A or B models.
Cutting edge performance
With outstanding on and off-axis response and superb directivity, the 1235A delivers a very wide and stable sweet spot that can be trusted by multiple listeners within a room. And through its integration with GLM software, the 1235A can be configured, controlled and calibrated for any type of acoustic environment, providing a truly optimised listening experience – and mixes that translate perfectly to other rooms and systems.

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.
