Speaker limiter thresholds for Low-Z Generic Speakers in Analog mode have been raised to the full amplifier output capability of 100Vrms / 150Vpeak, providing access to the complete output range of the MPA-Q. Previously, these limiters were set to 22Vrms / 56.5Vpeak. Existing designs using Low-Z Generic Speakers in Analog mode should review their output levels to ensure compatibility with the updated limiter values.

A new Privacy Mode option in Core Manager allows administrators to replace camera preview streams with a privacy image across Q-SYS Designer, UCI Viewer, Core Manager, and Reflect without affecting active conference streams.

From Core Manager and Peripheral Manager's Access Management Security page, the Maximum Concurrent Session setting is now increased from 5 to 20. This allows administrators to configure up to 20 simultaneous sessions per user account across devices and browsers (e.g., SSH, HTTPS). Exceeding the configured limit will be blocked.

For information on this or other Sign In Security settings, see Access Management > Security.

Q-SYS Designer now includes Canon firmware v1.0.1 for NC-Pro15x cameras, delivering meaningful improvements to camera responsiveness and streaming performance. Camera streaming latency — including RTSP/RTP and Mediacast (Q-LAN) streams — has been reduced by approximately 150ms, providing smoother, more consistent control-to-movement response and improved video responsiveness. Multicast streaming reliability has also been improved.

Users who have previously added an audio delay to compensate for lip sync alignment with NC-Pro15x cameras may need to adjust or remove that delay to match the reduced video latency.

This update requires a manual firmware upgrade. NC-Pro15x camera does not support automatic firmware upgrades on design push. Detailed instructions will be documented in a Knowledge Base article. For a quick reference, see the Core Manager Utilities topic. For references to camera control and control pin details, see the Status/Control (Cameras) topic.

The NC-Pro15x now supports XLR audio input (Left / Right via Input Terminal / MIC) for NDI|HDX audio transmission. This enables microphone audio to pass directly through the NDI stream, eliminating the need for a separate Mediacast audio path and simplifying signal flow for NDI-based installations.

YUY2 USB bridging formats now use full-range quantization, significantly improving color depth and contrast when viewing bridged camera video in collaboration applications such as Microsoft Teams, Zoom, and other UC host software. This resolves a washed-out appearance previously seen when comparing USB-bridged output to the camera’s HDMI output.

A brief walkthrough highlighting major updates and notable changes.

Peripheral Management is a new suite of tools found in the System Management section of Core Manager that enables faster deployment and centralized management of Q-SYS peripherals at scale. Rather than accessing each device's QPM webpage individually, you can configure network settings, DNS, Date & Time, 802.1x, certificates, and security settings for many devices at once, all from Core Manager. The toolset includes Bulk Configuration for provisioning devices via CSV upload or in-table editing, Bulk Certificate Management for centralized certificate oversight and bulk CSR generation, and Peripheral Utilities for administrative tasks such as password export, device reboot, and system information download.

For more information, see Bulk Peripheral Management (Beta feature).

The NVM Series brings a new era of simplicity and scale to video distribution. Designed for large‑venue environments—from hospitality to entertainment—NVM transforms how video systems are deployed, controlled, and managed.

With automatic source‑to‑destination association, no‑code routing, and system‑wide control panels that update instantly, NVM makes it possible to design and deploy expansive video systems in minutes. It scales effortlessly, adapts to any number of displays, and eliminates the traditional barriers between audio, video, and control. The result: NVM Series delivers platform‑native video distribution that’s easy to design, easy to deploy, and easy to operate. It’s streamlined video integration for modern spaces.

Go to NVM Series Endpoint Application for more information.

The NV‑32‑H and NV‑21‑HU can now operate in Mediacast Encoder Mode, enabling these devices to ingest HDMI video and distribute it directly to NVM‑302D Decoders within the same Q‑SYS design. This new capability lets you extend your AV‑over‑IP workflows by bridging existing NV Series hardware with the latest NVM decoder technology, creating a seamless path for scalable video distribution.

For more information, see HDMI I/O (NV-32-H) and AV I/O (NV-21-HU).

The NV-21-HU USB Video bridge now supports 1920x1080p15 YUY2 and 1920x1080p30 YUY2 video formats in the USB 3.0 UC&C YUY2 and HD YUY2 categories.

New controls for Active Speaker Framing and Tile View give you finer control over how the NC-90 camera frames participants. Deadband reduces unnecessary reframes caused by minor subject movement, keeping the camera stable until a subject crosses the threshold. Padding adjusts the space around detected subjects for tighter or wider crops. Framing Presets (Head, Head & Shoulders, Half Body, or Full Body) let you set how tightly participants are framed in both modes. Tile View framing is also now more consistent, with uniform participant sizing across tiles.

These controls are accessible in Q-SYS Designer Software under the camera's Auto Framing settings and take effect immediately — no restart required.

For more information, see Status/Control (Cameras)

A new Outline Body toggle is available in both Tile View and Active Speaker Framing modes on the NC-90-G2. When enabled, detected participants' bodies are outlined in the video output, helping verify framing accuracy and troubleshoot detection behavior.

This control replaces the legacy Outline Faces control in Auto Framing mode. The legacy control is grayed out for backwards compatibility. If you currently have it wired to a control script, it will remain functional. The legacy control will be removed in a future release.

For more information, see Status/Control (Cameras).

Face Count on the NC-90-G2 now operates independently of the active AI mode and works across all modes of the camera, including normal operation when no framing or AI modes are enabled. Previously tied to Auto Framing, Face Count polling can now remain active while using Active Speaker Framing, Tile View, or standard camera operation, enabling room occupancy monitoring and analytics at all times.

The new Face Count control replaces the previous Face Count control in Auto Framing mode on the NC-90-G2. The legacy control has been deprecated and is grayed out for backwards compatibility. If you currently have it wired to a control script, it will continue to function and remain in sync with the new Face Count control. The legacy control will be removed in a future release. NC-PTZ and NC-110 camera are not affected by this change and will continue to use the existing Face Count control in Auto Framing mode.

For more information, see Status/Control (Cameras).

USB Video Bridges wired to the new Mediacast Router now present a streamlined control panel with three tabs — Camera Controls, Bridge Controls, and Status. The Bridge Controls tab brings together privacy and auto-privacy features in one place: All Cameras Privacy places every camera on the connected Mediacast Router into privacy mode, while Camera Privacy controls the selected camera individually. Auto-privacy behavior is now more configurable with dedicated AP Calibrate and AP Reset Router buttons. When auto-privacy triggers after the AP Delay timer expires, you can choose whether cameras recalibrate and whether the router resets to input 1. USB Video Bridges wired to a Camera Router continue to show the legacy camera control tabs.

For more information, see USB Video Bridge.

The new Mediacast Router expands video routing capabilities beyond camera-to-bridge workflows. Route Mediacast streams to NVM displays and distribute video across separate Q-SYS systems using System Link — all from a single crosspoint routing component. Output Enable controls let you mute individual outputs without changing your routing selections. The original Mediacast Router has been renamed to Camera Router and continues to work alongside the new component in the same design.

For more information on the new Mediacast Router Component, see Mediacast Router.

Q‑SYS Designer Software 10.4 allows for the Sennheiser TeamConnect Ceiling Medium (TCC M) Plus to be used as a QDS component. Available under Audio – Other in the Inventory, the TCC M Plus integrates directly into Q‑SYS designs with no plugin required. The Sennheiser TCC M Plus now features Q‑SYS Extension for Sennheiser PartnerLink, an enhancement that allows for direct integration with Q‑SYS Designer to be used as a component for streamlined audio routing and control.

For more information, see Status (Sennheiser TCC M Plus). For setup and configuration through Sennheiser Partner Link see the Quick Start Guide.

The Voice Activity Detector now delivers full‑bandwidth Voice Output signal, upgraded from the band‑limited output of the previous version. A new user‑adjustable, Look‑Ahead Delay control (0–100 ms, default 64 ms) provides precise alignment between the gated audio and detection events, giving designers greater flexibility and more natural‑sounding transitions.

For more information, see Voice Activity Detector.

You can now obtain a list of UCIs, page names, layer names, and layer visibility on a running design:

• Uci.GetLayerVisibility returns a table of UCI, page, layer names, and layer visibility status. Optionally returns the visibility status for a specified layer within a UCI page.

• Uci.GetUcis returns an array of UCI name tables.

• Uci.GetUciPages returns an array of page name tables in a specified UCI.

• Uci.GetUciPageLayers returns an array of layer name tables in a specified UCI and page.

For more information about usage, see the Q-SYS Extensions to Lua > Uci topic.

Q-SYS Designer Software now provides a Select All / Deselect All option for managing control pin visibility in the Control Pins panel. Instead of toggling pins one-by-one, users can select or deselect all control pins, or a subset, in a single action. When deselecting pins that are currently wired, a confirmation dialog protects against accidentally removing wired pins to prevent unintended design changes.
