Implementing TQ™ Processing

At Fulcrum Acoustic, we believe that a loudspeaker manufacturer should understand the challenges facing its customers, and do everything it can to help them meet those challenges. Among other things, this means recognizing that numerous digital signal processors (DSP) are available, and that the best processor for a given application is determined by factors beyond the requirements of the loudspeakers. We have committed to supporting a broad range of processing platforms at a very high level to ensure that Fulcrum Acoustic loudspeakers are easy to work with and so our customers can achieve the best results possible.

What form does this support take? In short, we confirm that the signal processor settings used with our loudspeakers are precisely correct. Since each manufacturer implements its DSP filters differently, we have assembled an extensive collection of processors. The settings for each individual loudspeaker and processor are entered and adjusted by measuring and carefully matching the complex transfer functions to our reference measurements.

The settings are published below in the most convenient format supported by each processor model (e.g., custom blocks, plugins, macros, super-modules, etc.). In cases where there is no paradigm for bundling filters the settings are published as a table.

Processor Capabilities

The settings we provide for each processor model make maximum use of its capabilities. However, not all processors are created equal – some are capable of providing the most advanced form of TQ processing; some are not. To simplify the differences between various processors, we have defined two classes of processor settings, called “Level 1” and “Level 2”. These classes are described below; their respective settings follow.

Level 1

Level 1 settings are appropriate for processors that provide a very specific type of filter – a fully addressable, fairly large Finite Impulse Response (FIR) filter. With this filter we can implement detailed frequency response adjustments; and more importantly, we can implement the precise temporal (time domain) filters that are responsible for the most remarkable TQ benefits. Fulcrum Acoustic loudspeakers tuned to Level 1 provide a crisp stereo image, enhanced soundstage depth, excellent separation between the components of a complex mix, increased resistance to feedback, improved arrayability, more seamless transitions between distributed loudspeakers, and a less fatiguing listening experience at very high SPLs.

Fulcrum Acoustic Plug-in for Powersoft Armonía Software

TQ Level 1

A Plugin allows Powersoft's Armonía Pro Audio Suite™ software to recognize and control FA Portable Series powered loudspeakers. Armonía software may be downloaded from Powersoft's Armonía Support Forum (registration required). There are two versions of the Plugin: one for loudspeakers manufactured prior to 2016 and one for loudspeakers built January 2016 and beyond. Determine this by looking at the product serial number. The first four digits are a manufacturing date code. xx16 designates a 2016 build. xx15 or less designates an earlier build.

MediaMatrix Logo

MediaMatrix NION

TQ Level 1

Created with NWare 1.7.2 software. Filters are bundled in Plugin files (*.npp). The FIR filters in the Plugins require NION processors to be set to a 48 kHz sample rate.

Level 2

Level 2 settings can be implemented on most professional audio DSP platforms. They use the standard complement of Infinite Impulse Response (IIR) high-pass, low-pass, and parametric filters – plus delay.  With this combination of filters, Fulcrum Acoustic loudspeakers are tuned for: natural-sounding spectral balance; a pleasing aesthetic balance between highly transient sources (such as percussion instruments) and less transient sources (such as human voice); uncolored vocals; and excellent intelligibility. A Fulcrum Acoustic loudspeaker tuned to Level 2 is a high-precision tool, capable of producing high quality speech and music and suitable for a wide variety of professional applications.
