Update

Updated sinewave generator to go up to 22 kHz

Improvements

  1. PSX amplifiers: Added 4-priority, 4-source backup strategy features that has 3 modes
    a Force: permanently assigns a source to a chosen input (Analog 1-4 or Dante 1-4). This source can then be applied to 1 or multiple outputs using the Matrix.
    b Signal Presence: set an input as priority 1, and an input as priority 2. When signal on your priority 1 choice drops below the threshold level (-68 dBFS for example) the amplifier will ‘failover’ to priority 2. You can repeat for priority 3 and 4 as desired. This ‘source’ can be then applied to 1 or multiple outputs using the Matrix.
    c Pilot Tone: set an input as priority 1, and an input as priority 2. This backup strategy mode has an adjustable pilot tone listening device. Inputs with a detected compliant pilot tone are granted with higher priority. Set the frequency and upper/lower threshold (in dBFS) of the pilot tone listening device. If no pilot tone is detected, the next priority (priority 2 for example) would be used. If you click ‘enable alarm T, the amplifier rear panel GPO (alarm out) can also be triggered.
  2. PSX amplifiers: added Advanced Alarms setup to amplifier properties window. These additional alarms can be sent out the rear panel GPO (alarm out) after they are configured and enabled.
    a Pilot Tone Voltage Alarm for outputs 1-4
    b Pilot Tone Load Alarm for outputs 1-4
    c Nominal Impedance Alarm for outputs 1-4 Note: No AC Mains, Thermal Stress, Standby Alarms are always on, always sending out all 4 alarm GPO outputs. Short Circuit, per output, is always on, but only sends out of the effected output channel.
  3. PSX amplifiers: added Analog Trim (-15 dB) to (+15 dB) feature to amplifier properties window to give users more adjustability.
  4. PSX amplifiers: changed Digital Sensitivity adjustment in amplifier properties window from 4 steps: 0, -12, -20, -24 dBFS to an adjustment range between -48 dB and +12 dB adding more adjustability.
  5. PSX amplifiers: added new Pilot Tone generator block to the fixed block diagram of each output. Pilot tone generators can be grouped. As one example, this Pilot Tone generator can be used in conjunction with Pilot Tone Voltage or Pilot Tone Load alarm to test the parameters.
  6. PSX amplifiers: Live impedance monitoring. The measure load test panel has been added to output blocks of PSX amplifiers. Right click the output block and select ‘measure load’ to open the measure load panel. Channel can be changed between output channels 1-4 if desired. Click ‘capture’ to capture and measure the load.
  7. PSX amplifiers: V Clip limiter can be enabled and is fully adjustable for custom presets. V Clip values can be saved to a custom preset file. V clip limiters can also be grouped if you want to apply changes to multiple v clip limiters at the same time.
  8. PSX amplifiers: updated firmware update procedure so the update provides more information during the update (sending the firmware file, XX % complete, writing the file to memory-XX % complete).
  9. PSX amplifiers: updated input matrix to add input mutes to the left side of the matrix, and removed mutes from the 8 individual input blocks (4 analog, 4 dante)
  10. EX/ESP processors: updated sinewave generator to go up to 22 kHz to support pilot tone configurations
  11. MSA12X: Added Dante to analog backup strategy with 2 modes:
    a Force: permanently assigns a source to a chosen input (Dante or Analog)
    b Signal Presence: Set Dante as priority 1, and analog as Priority 2. If Dante falls below a threshold preset threshold level, MSA12X will change to Analog. When signal is restored above that threshold in Dante, it will return to priority 1.

Bug fixes

  1. Addressed issue where some Bose Professional speaker presets had incorrect limiter settings when amplifier channel output mode was set to 70v or 100V. Effected presets such as DesignMax DM3 models were limiting too early when set for 70V/100V output mode.
  2. Resolved crashing in Windows 11 issue encountered in rare situations
  3. Defect where a mute group containing PSX Dante inputs is incorrectly muting Analog inputs on the device instead.
  4. Defect where devices with DHCP addresses are listed in batch network updates
  5. Defect where a part of the Ul on the control panel of the Limiter of the PSX amplifier may disappear, some builds of CSD 5.12 after copy/paste operation
  6. Fixed defect where notes may hide wires
  7. TCC2 GPO does not go high when the Call Status button is turned on while offline
  8. Defect where Zoom combo-box is getting narrower every time toggling system-mute
  9. Defect where EX1280C's VoIP output wiring points indicate mute state when MSA12X Dante Outputs are muted
  10. Fixed issue where Unhandled exception on changing PSX output modes after coming offline
  11. Fixed issue where Signal Generator mute of PSX is delayed immediately after going online
  12. Fixed issue where Input and Output mutes of PSX are delayed immediately after going online
  13. Fixed issue with mismatch of the Delay setting
  14. Fixed issue where PSXService throws error on PC restart when there are changes to be saved
  15. Fixed issue where Wires between logic blocks are removed by cut and paste of the logic blocks/wires
  16. Fixed issue where Unchecked devices showing active update status when "Sort" is applied
  17. Fixed issue where PSX relabeling outputs on a crossover object, output 1 assumes the label of output 2
  18. Fixed issue where PSX Audio is muted when Signal Generator is on and no channels selected in Matrix
  19. Fixed issue Mismatch of the selection of the "Audio Check" of the MSA12X. Closing audio check window will now mute audio check.
  20. Fixed PSX issue Parameters needed to be disabled may be erroneously enabled
  21. Fixed issue where Pilot Tone frequency should only show whole Hz, without decimals
  22. Fixed issue where SpeakerPEQ align delay conversion is slightly wrong
  23. Fixed issue where EX-4ML becomes unresponsive after saving/loading presets via command with CSD open
  24. Ensured ArrayEQ parameters in CSD reflect changes made via SolP

Changes

  1. Moved PM4500N from current to 'Discontinued' in device tree view
  2. Adjusted appearance and numbering of Analog/Digital inputs in project view for PSX amplifiers

Open problems

PSX Amplifiers Settings in Device

  1. PSX cannot act as RTC/Main device during phase 1
  2. PSX cannot allow parameter sets, CC-xD, CSR controls to dynamically control the amplifier when the PC is offline during Phase 1
  3. PSX cannot use timers
  4. PSX Power-On state is always ‘restore last settings’ and this cannot be toggled off
  5. All inputs wake up PSX from standby and you cannot limit it to less inputs

PSX Amplifiers Signal Processing

  1. PSX amplifier’s limiter behaves differently than PowerMatch or PowershareD, therefor custom limiter presets have been loaded in the Bose Professional Loudspeaker EQ preset files bank that come with CSD 5.13. They contain different values than PowerMatch or PowerShareD amplifiers.
