Qt Pro release notes

6.7.2

Released September 2019

New Features:

  • SageVue support added
    • Qt300 and Qt600 are now integrated in Biamp’s SageVue software
    • Firmware update required for use

Updates:

  • Reintroduction of Bridge Mode Cable support:
    • Previously removed when Active Emitter introduced
    • Doubles (+/- resistance) the RMS output of the Qt Standard emitter
      • Must be used with Bridge Mode Cable (sold separately)
      • *Warning, do not attempt to use with Active Emitter*
  • Qt Command Center support added for bridge mode, and SageVue
  • Bug fixes (unspecified)

6.7.1

Released January 2019

Updates:

  • GUI Updates for:
    • Time of Day Ops types
    • Auto Ramp
  • Added Time of Day type to URL address (&schedType=)
  • Initialize Auto Ramp dates to correct size to include buffer
  • Auto Ramp disables upon completion of ramps
  • Initializing Input A/B to ‘15’ for testing

Resolved software issues/bug fixes:

  • Updated MCS “Modify Mode” to reflect Auto Ramp Status
  • Added functionality to Daylight Savings setting
    • If the majority of countries within a time zone utilize southern hemisphere DST settings, the menu options change to the southern hemisphere DST calendar options
    • for instances in which a country uses northern hemisphere and the DST dropdown options reflect the southern hemisphere, CLI commands can be given to reverse the action
    • Daylight Savings CLI commands:
      • CSGET,IDST = 0, the Daylight Savings dropdowns are reflecting
      • CSGET,IDST = 1, Daylight Savings dropdowns are inverted for the Southern Hemisphere
      • CSGET,IDST = 2, the Daylight Savings dropdowns will reflect only the northern hemisphere calendar options. (Locked)
      • CSSET,IDST = 0, the Daylight Savings dropdowns function according to new changes
      • CSSET,IDST = 2, the Daylight Savings dropdowns are locked to only reflect the northern hemisphere options

6.6.1

Released January 2018

Updates:

  • Setting time/date on the RTC (Administration tab) will cause the Auto Ramp to recalculate the state and proper masking level
  • The initial masking level on Auto Ramp start and after a settings change will now be calculated and updated immediately, but all other masking level changes will occur at midnight. In version 6.6.0 it defaulted to the start level and only updated at midnight
  • Reduced the delay on an Auto Ramp settings change to get updated masking volume
  • Any masking level change from the front panel will now disable the Auto Ramp
  • CLI: When using the ENAR opcode to enable Auto Ramp it will do a validity check on the dates to make sure they are correct. The ZOSET,ENAR=1 will respond with a NAK if dates are invalid
  • Added a text alert and some text on the Auto Ramp form to inform user that Auto Ramp changes may take up to a minute to take effect

Resolved software issues/bug fixes:

  • If the ramp rate is lower than 0.5dB per day the ramp will turn into a step at the last day

6.6.0

Released November 2017

Updates:

  • Implemented a new Auto Ramp feature that allows calendar based ramping of masking with up to 3 ramps and 3 constant values. Auto Ramping will inactivate Time of Day ramping until the Auto Ramp reaches its final masking volume (Time of Day Max) which stays for a day. Added a set of CLI commands to cover this feature
  • Expanded the Min/Max Time of Day Schedule to include Audio A and Audio B. Added separate Ramp to Max/Ramp to Min times, Ramp Intervals and Min/Max levels. The feature also includes added CLI commands
  • Changing the emitter type now causes the masking equalizer to be reset back to default settings
  • Added commands to the CLI for Input A/Input B sensitivity and Masking Min increment and decrement commands

Resolved software issues/bug fixes:

  • MCS Password Requirements: resolved issue with certain characters, which did not show up properly if used as part of the password and were replaced with a ‘-‘. Implemented a check to make sure that these characters are not used in a password
  • The UI was allowing the enabling of fault detection on zones that were set as Qt AE zones. Since the Fault Detection is disabled on AE zones this change makes the UI match the functionality
  • Fixed bugs that were affecting the following:
    • adjustment of masking levels on the front panel of the Qt controller
    • updating of equalizer settings for Audio A and B
    • updating of Masking equalizer settings in the 6.3KHz band
    • changing from SteelCase mode to CSM mode, or vice versa, would reset all settings back to default
    • using the ZOSET commmand in the CLI to set Audio A and B equalizer settings

6.5.2

Released May 2017

Updates:

  • Re-instated temperature protection code, so that if temperature reaches 65°C the controller will shut down masking and audio
  • Enabled use of Qt Command Center version 2.1.4.5 for saving and restoring parameters including emitter type and spectrum

Resolved software issues/bug fixes:

  • CLI was not accepting Zone Set commands to set the masking equalizer 

6.5.1

Released December 2016

Updates:

  • Active Emitter Spectrum type was not previously supported in CLI, added ‘SPEC’ command to support setting and getting the spectrum type
  • Audio Input Equalizer has limited frequency bands available for STD emitter. The 2 lower bands (250Hz and 500Hz) were disabled

Resolved software issues/bug fixes:

  • CLI commands INCM and DECM were being rejected
  • Both Audio A/B inputs were affected (muted) by either one of them being muted

6.5.0

Released September 2016

Updates:

  • Support added for Qt Active emitters
    • MCS UI updated to allow selecting an Emitter Type (STD or AE) on a per zone basis
    • Emitter type indication shown on the front panel display of Qt 300/600 for masking volume and audio volume
      • will show either ‘Qt’ for Standard emitter or ‘Qt AE’ for active emitter
    • Added STD Masking spectrum to AE emitters. The user can now select between AE spectrum and STD spectrum through the MCS software.
      MCS UI updated to allow selecting the Spectrum type when selecting Emitter type. Note: this property is not yet implemented in the CLI

Resolved software issues/bug fixes:

  • Fixed issues in CLI where the INPA and INPB Audio Input levels were set and read correctly but did not take effect in the DSP
  • Fixed the A/B sensitivity controls from the MCS UI which did not work. Updated to 3 levels: Low Level (+12dB boost), Normal Level (0dB gain boost) and High Level (-12dB attenuation)

6.3.0

Released June 2015

Updates:

  • 0.5dB control of masking volumes has now been fully implemented
  • A special Mute Button has been added to the Operations Page of the web interface. This Mute Button is made available in Modify Mode, but not in Review Mode
  • Telnet Command Line Interface (CLI) has been implemented

Resolved software issues/bug fixes:

  • In previous versions, if the masking volume was changed from the Front Panel, then the Day/Night ramp settings were completely eliminated in all six zones. This has been fixed, so that only the zone for which masking volume is changed will see the termination of the Day/Night ramp setting

6.2.0

Released October 2014

Updates:

  • Bootloader version 3.0 released simultaneously with firmware release

Resolved software issues/bug fixes:

  • Qt300 fault zone naming

6.1.0

release date n/a

Resolved software issues/bug fixes:

  • Saving of Auto Ramp settings

6.0.0

release date n/a

Updates:

  • Configuration changes made via the front panel LCD are now saved immediately. In earlier versions, only changes made through the MCS were saved
  • Auto Ramping levels are now saved in persistent memory, to ensure that the duration of the ramp stays on schedule when the controller is not powered
  • Changed from "day/night" masking to "max/min" masking level concept:
    • Supports wider range of masking start times and ramping rates (24 hour time range per setting)
    • Masking level calculations changed to support new min/max concept, reversible order, and more flexible time settings
    • Adds popup warnings in MCS if user tries to submit configurations that would behave unusually or illogically. (e.g. warn against and reject a ramp interval selection that is greater than the time delta between Min start and Max start times)

Resolved software issues/bug fixes:

  • Improved Emitter Network Fault Detection process to reduce false positives
    • Added code to Short Detect to not check for shorts if paging is active
    • Examine paging levels as part of process of determining if short is present
    • Simplified screen to activate and deactivate fault detection per zone
