Bose EQ in FIR Designer: Bose Professional IIR Mode
FIR Designer DSP software can now be used to design and load EQ to Bose Professional Sound Processors and PowerShareX, PowerShare & PowerMatch amplifiers.
The new ‘Bose Professional’ IIR filter mode in FIR Designer v4.5 (& FIR Designer M) enables the design of custom EQ for loading into the IIR filter-based signal processing blocks (PEQ blocks) in Bose’s ‘ControlSpace Designer‘ professional configuration & control software.
The Bose filter emulation in FIR Designer ensures that common IIR filters, used to configure DSP functions for EQ, will produce consistent results when used in Bose products. Brand-specific IIR emulation is necessary for audio optimization because some filters produce different results when used across processor brands. Bose and Eclipse Audio have worked together to ensure that the Bose IIR filter mode in FIR Designer interprets filter parameters in exactly the same way as ControlSpace Designer. (Learn more about IIR brand emulation.)
The Bose Professional IIR filter mode contains options for parametric, low-shelf, high-shelf, notch and Butterworth (1st & 2nd order filters) high-pass and low-pass filters; all of which can be saved & exported as a *.peq file format for upload into a ControlSpace Designer PEQ block. (FIR Designer also contains Bose-emulating Bessel and Linkwitz-Riley filters, although those are currently not supported in PEQ blocks.)
Bose EQ Conversion
IIR filters developed for other audio brands can now also be converted for use in Bose processors and amplifiers (and vice-versa), using the IIR Reference Editor in FIR Designer. Including Bose Professional, there are currently sixteen branded IIR modes available:
(The generic mode is for use with processors without their own branded mode. Learn more).

Brand-specific EQ options: IIR filter modes in FIR Designer
In addition to filter conversion between brands, a measurement (in a supported file format) of an IIR response from any processor can be loaded into the ‘Target’ tab of FIR Designer , and the Bose filters can be set to match it in the ‘IIR Filters’ tab.
