Resolved Known Issues

Loudspeaker Status is "OK" when the Amplifier has no Connections to Anything in the Design.

Issue: When you have loudspeakers connected to an amplifier in a Q-Sys design and the inputs to the amplifier have no connections in the design, the loudspeaker Status reports "OK".

This issue is fixed.

I/O Input Card Meters do not Work When There is no DSP Wired to the I/O Input Component in the Design.

Issue: If you have an I/O Input card (AES3, CobraNet, Mic/Line In) installed in an I/O Frame, with an audio source connected to the inputs of the card, but nothing connected to the outputs in the design, the meters in the Control Panel of the I/O Input card, do not work. All the other functions appear to work, for example Phantom Power. This situation gives the impression that the input source is not working.

This issue is fixed.

Release 2.1.452

Issue: When using the Bookmark feature in a UCI, with the Show Full Screen option checked, the screen displays in full screen, and in Touchscreen Control Mode even though Touchscreen Control Mode was not checked when the Bookmark was saved. In addition, when only the Touchscreen Control Mode was checked, the UCI did not display in Touchscreen Control Mode.

This issue is Fixed.

Issue: When the UCI has been running for 60 seconds, the screen displays a blank white page.

Workaround: Make sure you configure the AUX ports, on the backup Core, properly.

Issue: On very large, redundant systems, Q-Sys occasionally dropped a flurry of packets on all output streams, on the active Q-LAN network (usually LAN-A). This problem happened on redundant Core design when the active Core would update the backup Core (every 10 minutes) with the Global Snapshot, Page Configuration Info, and the Admin Log File. If the design is very large and the paging configuration extensive and very busy, along with other events, this periodic data-transfer between the Cores could cause intermittent Q-LAN packet drops.

This issue is mitigated to an unnoticeable level. The issue will be fixed in release 2.2.

Issue: When upgrading to 2.1, if your Core is password protected, an error would display during the media backup process.

This issue is Fixed.

Issue: Cannot update firmware to 2.1 on a password-protected Core.

Issue: Cannot deploy UCIs to a password-protected TSC-8.

This issue is Fixed.

Issue: Cannot deploy firmware to password-protected TSC-8.

Workaround: Remove the password from any TSC-8 you plan to update to the latest 2.1 release. After updating the TSC-8, add the password protection.

Release 2.1.439

• PA Router – When the product of PA Zones * BGM Inputs is greater than 4K (64*64), the BGM source select crosspoint buttons were not functional. The crosspoint buttons are functional up to the maximum PA Zones * BGM Inputs (256 * 64), or 16K.
• DAB-801 with Redundant I/O Frames – Q-Sys Designer occasionally misidentifies an amplifier when the system is switching between redundant I/O Frames with the DAB-801 Automatic Mode button OFF, and a Manual Backup Engage Button ON.
• DAB-801 with Redundant I/O Frames A 4-Channel Amplifier would occasionally lose Channels 3 and 4 when switching between redundant I/O Frames with the DAB-801 Automatic Mode button OFF, and a Manual Backup Engage Button ON
• Uploading Large Audio Files – Occasionally when you try to upload a large audio file to the Core, the process will stop without uploading the file or giving an indication that the process stopped, other than the progress bar is not moving.
• Preview Audio Files in Sub-directories – If you create a sub-directory under either the Messages or Preambles directories in the Audio Files tab, upload either .wav or .mp3 files into those sub-directories, and then attempt to preview one of those files by clicking the play button next to the file, no audio is produced.
• Access Audio Files in Sub-directories – If you create a sub-directory under either the Messages or Preambles directories in the Audio Files tab, and upload either .wav or .mp3 files into those sub-directories, then attempt to use those files in any commands, the files do not display in the list of available files.

Release 2.0.329

• This is an update from 2.0.325 and it fixes a few bugs. 
  

Release 2.0.325

• When a Q-Sys design contained at least one I/O Frame fully loaded with AES cards, and all channels on the AES cards are used, the LCD on that I/O Frame, and Configurator display for that I/O Frame may have become sluggish. In addition, this situation could have resulted in the inability to update Q-Sys Designer versions.
• Under some conditions, the Audio Player may have experienced audio dropouts.
• A memory leak in the Audio Player may have resulted in a Q-Sys design fault/restart, or various other problems. Using a greater number of Audio Players, playing for a longer period of time caused the fault to occur sooner.
• In Q-Sys Administrator, Scheduled Event – Advanced Settings features were not working.

Release 2.0.320

• In a Q-Sys system with multiple Cores, running different designs, on the same PTP clock domain, an audio engine restart on the Core with clock mastership could invoke a state where audio streams would drop for an extended period while the Q-Sys components within the clock domain attempted to resynchronize to the clock master.
• Under some circumstances, when there is a large amount of network traffic, Q-Sys would periodically drop audio packets. This issue is resolved.
• In locales using commas for numeric dividers (German, for example), the UCI panel would not display when it was clicked in the discovery list. Now, the UCI panels display in locales other than the United States.

Release 2.0.314

• An eight-channel amplifier connected to two DataPort cards occasionally caused Q-Sys Designer to detect only the first two channels of the amplifier. This issue is now resolved.
• A Core 1000 requires a minimum of 2 GB of RAM to run a Q-Sys Design with a Page Router in the design. Now, a Save to Core & Run fails, with an error message indicating the problem, if there is a Page Router in the design and the Core 1000 has less than 2 GB of RAM.
• The Pilot Tone level (Loudspeaker Component) was too low to get an accurate reading of impedance for some combinations of amplifiers and loudspeakers. The Pilot Tone level was increased to improve performance.
• A Page Station, without a numeric keypad, displayed the message "Logon Required" prior to configuration in the Q-Sys Administrator. This no longer occurs.
• The Custom FIR Filter now works in Multi-Channel mode.
• You can now save the Custom FIR Filter in a Snapshot.
• The Low-Pass and High-Pass FIR filters now work in Multi-Channel mode.
• The Audio File Player has three linked fields to specify the file to play: Root, Directory, and File. Previously, if the directory or file specified by any of these fields does not exist, Q-Sys clears that field, and those below it. Under some circumstances, the Root, Directory and/or File fields in the Audio File Player lose their settings. Now the field, and those below it, are not cleared, but turn red to indicate the situation.

Release 2.0.310

Release 1.2.242

• Q-Sys Designer cannot connect to a Core on its AUX LAN ports.
• The Audio Player occasionally causes the Core to restart the design within the first minute after starting, if the design is saved with the Audio Player in the looping state. On rare occasions, the design may restart after the Audio Player has been playing for a long time.
• When an Audio Player file selector control is placed in a User Control Interface page, it does not display properly (scale) on a remote interface.
• When a redundant network system fails over from LAN A to LAN B, the audio output starts making a"popping" sound after about 15 minutes, then is lost completely after a few more seconds.
• When a Crossover Component has more than one channel, the Master Gain, Master Mute, and Master Invert, controls only control the first channel.
• When a Graphic Equalizer Component has more than one channel, the Master Bypass button bypasses only the first channel.
• If you have, a 4-channel amplifier connected to a DAB-801, and switch from the active I/O Frame to the standby I/O Frame, with the Automatic Mode button ON, the amplifier is identified correctly but channels 3 and 4 of the amplifier are occasionally lost.
• You can assign a Custom Voicing component to a Generic Distributed Loudspeaker in the loudspeaker's Properties, but when you click away from the loudspeaker component, the assignment is lost.
• If you have an I/O Frame-redundant system, and the active I/O Frames is disconnected then reconnected, the reconnected I/O Frame becomes active for a short period of time and could cause an interruption in the audio.
• If you copy then paste a Container component, containing any Inventory component, the design is corrupted. The Container component, after pasting into your design, would no longer contain the Inventory component, but the wiring would still be in the container. In some cases, you could not wire anything to the Container component. Currently, if you copy and paste a Container with an Inventory component in it, the Inventory component is added to the Inventory list.
• Upgrading from Q-Sys Designer 1.0 or 1.1 - In version 1.1, Signal Links were replaced by Signal Names. If you upgraded from 1.0 to 1.1, the Signal Links worked, but could not be modified. Conversion to Signal Names was accomplished manually. In this release of version 1.2, you are given the option to have the Signal Links in your 1.0.x design converted to Signal Names or not. If you choose not to convert the Signal Names, they work as described above. If you choose to convert them, and there are any Signal Links in your design that are not connected to anything, they are deleted. The first channel of any multi-channel Signal Links is converted to a Signal Name, but the subsequent channels are deleted. You must rewire them manually. All other Signal Links are converted to Signal Names.
• In version 1.2, Loudspeaker Custom Voicing was moved to Inventory. If you upgraded from 1.0 or 1.1, Custom Voicing would be lost if the Loudspeaker or Loudspeaker component was selected and the Custom Voicing was not in Inventory. This release of version 1.2 automatically converts existing Loudspeaker Custom Voicing to Inventory. IMPORTANT: As in any upgrade, it is important to make a backup of your design files before upgrading.
• The limit to the Loudspeaker Custom Voicing Alignment Delay control was 10 ms, however, the underlying implementation limits the value to 2 ms. The usable and adjustable value is now 5 ms.

Release 1.1.181

• When the graphic level indicator from a Meter component is placed in a User Control Interface, it does not display the peak level, only the RMS level is displayed.
• When attempting to display a User Control Interface on a Windows PC, the connection fails. This should only be a problem on Windows networks.
• Q-Sys does not allow copies of any I/O Cards, however, if the I/O Card is inside a Container Component or a Channel Group Component, the Component can be copied multiple times resulting in more than one I/O Card in the same slot of an I/O Frame or Core.
• When you place a control in the External Control pane, then the Properties of the Component, from which the control was taken, are edited, the control is removed from the External Control list.
• Changing the Filename drop-down Control of the Audio Player, and then quickly pushing Play will sometimes result in the Audio Player not playing or in some audio from the previously loaded file being played. This probably only happens with very quick control changes issued through external control or from script.
• The limiter reduction meter was removed from distributed loudspeakers, but the limiter was not actually disabled.
• When the PWM frequency is set in the I/O Frame GPIO, the output frequency is about 6.7% higher than what was specified by the user. The output is now correct.
• Designs using the Audio Player component may experience an extreme slowdown of the Core, and loss of audio to any I/O Frames in the system. The greater the number of Audio Players in the design, the symptoms occur sooner and are more severe.
• The Current Gain, in the Gain Ramp Component, indicates the gain that is being applied to the signal. Previously, the Current Gain would show -120dB even though the actual gain was somewhere in between gains A and B. This has been corrected. The Current Gain now shows the actual gain as it is being ramped between gains A and B.
• It was not possible to edit the Signal Name of a Snake pin if the other end of the Snake also had a Signal Name.
