Embodiment Construction

[0039] Newer amplifiers for powered speakers offer flexibility because they use digital signal processing. This means that the cabinet calibration can be adjusted by utilizing the DSP (Digital Signal Processing) capabilities to set the correct filter coefficient values ​​into the amplifier unit's memory.

[0040] exist figure 1 A typical implementation is presented in relation to an active loudspeaker 1 comprising a cabinet 5, driver 2, amplifier electronics 3 and necessary inputs (not shown) for power and signal.

[0041] According to the invention, a memory chip 4 is built into or fixedly connected to the speaker cabinet 5, and this memory chip 4 in the cabinet contains the equalization filter for the required in order to produce a properly equalized Individual and unique cabinet-related factory calibration settings for your speaker system.

[0042] A typically serial communication link is established inside the housing 5 between the chip 4 and the amplifier electronics 3 ...

Abstract

The invention relates to a method and a loudspeaker for storing equalization settings in an active loudspeaker (1) comprising a loudspeaker cabinet (5), at least one driver ( 2) and amplifier electronics (3) including an equalizer (8), in which method the loudspeaker (1) is calibrated under controlled conditions for forming factory calibration parameters for controlling the equalizer (8), controlling the equalization The factory calibration parameters of the amplifier (8) are stored in the amplifier electronics (3). According to the invention, factory calibration parameters are also stored in a memory (4) fixedly mounted to the loudspeaker (1).

Description

technical field [0001] The present invention relates to a method. [0002] The invention also relates to a device. [0003] In general, the invention relates to active loudspeakers with built-in amplifiers, or alternatively each driver of an active loudspeaker may have a separate audio channel with its own filter and amplifier. [0004] In particular, the invention relates to methods and devices for storing and restoring equalization settings in active loudspeakers. Background technique [0005] In speaker systems where the amplifier is not built into the speaker cabinet, the amplifier is usually calibrated separately with the enclosure and its driver. This makes the cabinet and amp into an already matched pair. Therefore, it is not possible to use an amplifier from another speaker system of the same type with a given enclosure. [0006] This leads to several practical problems in installing loudspeakers. These questions include: [0007] l Amplifier-speaker pairs can ...
