Firmware 1.7.3

Features:

• Updated power management text to reflect compliance standards and Dante features.

• Updated BTL mode text to meet compliance standards (applicable to PowerZone™ Connect 1U series only).

Bugfixes: 

• Resolved issue preventing speaker presets from being applied from the library.

Firmware 1.7.2

Features & Improvements:

Features

• Enabling BTL mode / Bridge mode on 1U units.
  • This has always been enabled for 2U units, but it is now enabled on 1U units as well, so the installer can bridge two output channels together.  

Bugfixes

• Pop issue on SPDIF In/Out on Dante has been resolved

Firmware 1.7.2

Features & Improvements:

Bugfixes

• Input box shrinking to a very small size
  • Clearing an input box (e.g., Gain) and then clicking the “X” button is resulting in the text box shrinking to as small as it can be drawn, with X and check icons squished together
• Incorrect position of a slider
  • When clicking “Enter” on an empty input field (e.g., Gain), the slider moved. This is now fixed, so that the slider does not move if the input field is empty.
• Speaker Preset issue
  • Issue resolved with speaker presets, so that the user can load them again on the amplifier.
• Bridge mode on 2U amplifiers was missing
  • This is now resolved and 2U units are now recognized again as 2U units.

Firmware 1.7.0

Features & Improvements:

FW 1.7.0 is a bigger firmware, which firstly provides end user access to the amplifiers, while also having changes within the frontend/maintenance.

There are no bugs nor other major changes within the UI other than a small enhancement displaying e.g., “A+B” in the tabs, when combining two zones in stereo mode.

User Control

End users have now a simplified interface with essential controls:

• “All Zones”
  • Instantly mutes all zones.
• Zone Overview:
  • Adjust volume
    • Turn it up and down and adjust the volume
  • VU-meter:
    • Displays current audio output for each zone.
  • Mute Button:
    • Allows individual zones to be muted.
  • Zone/Input Selection:
    • Facilitates switching between different zones or inputs.
  • Mix Editing:
    • Permits adjustments to the audio mix.

Access restrictions:

• End users are limited to the page “User Control”.
• Installers can log in for advanced settings and configurations. This is setup through the tab “Security”, where they first setup a PIN which ensures that it is only an installer that can access the configuration of the amplifier, while the page “User Control” is accessbile to end users.

Guide to setup “User Control”

1. Update the amplifiuer with firmware 1.7.0.
2. Enter “Security” of the amplifier.
3. Enter a password and click “Apply”.
4. Enable “User Control” and select what zones to show for end user.
5. Click “Apply” in the top right corner.
6. Click “Log out” in the bottom right corner.

Code refactoring / UI Components

The Software Team has done changes in the frontend, which ensures that all buttons are based on components. The buttons therefore look different compared to versions earlier than firmware 1.7.0. The changes ensure better maintenance and improves testability of the application.

An overview of the affected areas is provided below.

Examples are chosen from each of the respected firmware, so it is easy to see the difference between the two firmware.

Area 1 – Button arrangement (EQ)

Firmware 1.6.7

Firmware 1.7.0

Primary buttons are placed towards the right, while the secondary buttons from left to right.

Area 2 – OK replaced with Close

Firmware 1.6.7

Firmware 1.7.0

Area 3 – All toggles (when toggled/enabled)

Firmware 1.6.7

Firmware 1.7.0

Area 4 – Secondary buttons e.g., “Reset” is outlined

This goes throughout the entire GUI, so all secondary buttons are marked with an outer line.

Area 5 – Speaker preset (button alignment)

Firmware 1.6.7

Firmware 1.7.0

Area 6 – Disabled buttons are “clear” (e.g., example with button “Clear”)

Firmware 1.6.7

Features & Improvements:

New features

• Speaker presets can now be generated, imported and exported. 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. The speaker preset function is located under the output settings menu.
• An internal speaker library for storing speaker presets locally within the amplifier has been added. The speaker library is located under the general settings menu.
• All speaker related settings (equalizer, driver alignment, crossover etc.) are now contained within the new speaker preset function, located under the output settings menu.
• Several enhancements to EQ settings have been made, as outlined here (secton 1-5):
  1. Butterworth 36dB/octave and 18dB/octave high pass and lowpass filters are added to the crossover section for increased flexibility and compatibility with existing speaker presets.
  2. Low shelf 6dB/octave and High shelf 6dB/ octave filter types are added to the EQ and speaker EQ sections for increased flexibility and compatibility with existing speaker presets.
  3. Low shelf 12dB/octave and High shelf 12dB/ octave filter types are added to the EQ and speaker EQ sections for increased flexibility and compatibility with existing speaker presets.
  4. Low pass 6dB/octave and High pass 6dB/octave filter types are added to the EQ and speaker EQ sections for increased flexibility and compatibility with existing speaker presets.
  5. All Pass (1st order) filter type are added to the EQ and speaker EQ sections to complement the All Pass (2nd order) filter for increased flexibility with speaker and room tuning.
• The output limiter section has been improved with RMS limiters to complement the peak limiters. (Note: RMS limiters are most typically used to protect the connected loudspeakers from thermal overload).
• RMS limiter now adjustable in 70V and 100V
  mode.

  show the combined speaker EQ and crossover
  response.

  the load is well known, and the designer adjusts
  the system to avoid overload.

  sockets API is now added for systems supporting
  this protocol.
