Blaze Audio Announces the PowerZone Connect V1.2 Firmware Update

Loudspeaker management, equalization enhancements, limiter functions, and more

Greensboro, NC – August 2022

Blaze Audio, a manufacturer of professional solutions for commercial audio applications and a subsidiary of Pascal A/S of Copenhagen, Denmark, is pleased to announce the Version 1.2 firmware update for the company’s PowerZone Connect ( Series of power amplifiers. Offering a combination of new functionality and feature enhancements, including hassle-free integration of PowerZone Connect amplifiers with four of the most widely specified control and automation systems (Q-SYS, RTI, Control4, and Creston), the V1.2 update is a compelling upgrade that AV system integrators will certainly appreciate.

Loudspeaker preset management is a substantial element of the new V1.2 update. For starters, loudspeaker presets can now be generated, imported, and exported, enabling installers to instantly ‘tune’ the loudspeakers of many major brands when connected to a Blaze PowerZone Connect amplifier. During export, it is possible to choose exactly which parameters (equalizer, crossover, delay etc.) should be included in the preset, and which should remain protected. Further, an internal library for storing loudspeaker presets locally within the amplifier has been added. Equally notable, all loudspeaker related settings (equalizer, driver alignment, crossover etc.) are now contained within the new loudspeaker preset function.

With the V1.2 update, several enhancements to system EQ settings have been implemented for increased flexibility and compatibility with existing loudspeaker presets. This includes Butterworth 36dB/octave and 18dB/octave high pass and lowpass filters that have been added to the crossover section, along with Low shelf 6dB/octave and High shelf 6dB/ octave filter types that have been added to the EQ and loudspeaker EQ sections. Low shelf 12dB/octave and High shelf 12dB/ octave filter types have also been added to the EQ and loudspeaker EQ sections for increased flexibility and compatibility with existing loudspeaker presets.

The V1.2 update also makes Low pass 6dB/octave and High pass 6dB/octave filter types a new addition to the EQ and loudspeaker EQ sections for increased flexibility and compatibility with existing loudspeaker presets. Additionally, an all Pass (1st order) filter type is added to the EQ and loudspeaker EQ sections to complement the All Pass (2nd order) filter for increased flexibility with loudspeaker and room tuning.

To protect the connected loudspeakers from thermal overload, the new V1.2 update introduces improvements to the amplifier’s output limiter section by way of RMS limiters to complement the peak limiters. The RMS limiter is now adjustable in both 70V and 100V modes.

The V1.2 update includes a switch that has been added to the loudspeaker EQ settings to show the combined loudspeaker EQ and crossover response. Further, each output now supports loading an FIR filter up to 512 taps (48kHz) to be included in the loudspeaker presets. The output limiter section has also been improved with a Clip limiter disable function. This is normally only used when designing subwoofer presets where the load is well known, and the designer adjusts the system to avoid overload. Integrators will also appreciate the fact that, in addition to the Web socket API, a Raw TCP sockets API has been added for systems supporting this protocol.

In addition to the aforementioned improvements provided by the V1.2 firmware update, there are also several additional enhancements. These include:

  • WI-FI client mode is now supported.
  • The maximum Q of parametric, Notch, Lowpass, and high pass filters has changed from 10 to 30.
  • The Driver alignment enable switch default has changed from enabled to disabled.
  • A Zone Compressor parameter hold time has been added.
  • The Output limiter name has changed from ‘Limiter’ to ‘Peak limiter. (The function itself remains unchanged.)
  • The (peak) Limiter maximum attack time has increased from 50ms to 100ms.
  • The (peak) Limiter maximum release time has increased from 1000ms to 2000ms.
  • A (peak) Limiter knee parameter has been added.
  • The Equalizer name has changed from ‘Equalizer’ to ‘EQ’.

Kevin Wilkin, Blaze Audio’s Executive Sales Director for the Americas, commented on the V1.2 firmware update for the PowerZone Connect Series amplifiers, “This update brings an extraordinary assortment of enhancements to an amplifier line that was already rich with features. The extent of the loudspeaker management as well as the new EQ and Limiter capabilities is nothing short of exceptional. Further, this update includes custom-made drivers for use with Q-SYS, RTI, Control4, and Creston control and automation systems. In addition to the documented improvements, there are also several other minor GUI changes and bug fixes. This update brings a dramatic upswing in overall functionality to a product group that already had a rich feature set—and it only takes roughly 2 minutes to install. I am confident that AV system integrators will find much to like with these new improvements to the PowerZone Connect Series.”
