Cambridge NMS-NG10GPX-AVB Switch by Netgear - 911.1966.900

Product Overview

The Cambridge NMS-NG10GPX-AVB (part number 911.1966.900) is a pre-qualified network switch for Qt X sound masking deployments, based on the NETGEAR GSM4212PX platform. AVB (Audio Video Bridging) networks require switches that support the protocol's time-synchronization and bandwidth-reservation features, and this model is validated for use with Cambridge Qt X control modules. Specifying a known-good switch removes network compatibility risk from multi-controller masking, paging, and music systems. It is the backbone component that lets Qt X controllers share audio inputs across a building.

Product Description

In Qt X systems with more than one control module, audio from paging stations and background music sources is distributed between controllers over an AVB media network. Standard enterprise switches do not pass AVB streams; the network must use AVB-capable hardware end to end. The NMS-NG10GPX-AVB is supplied specifically for this role, providing the switching fabric for Qt X 300, 600, and 805 controllers and NPX paging stations on the media network. Pairing the switch with the rest of the Cambridge ecosystem keeps the system on a single validated bill of materials, simplifying commissioning and support. PoE capability on the NETGEAR GSM4212PX platform also supports powering compatible network endpoints such as NPX paging stations. For the controllers, emitters, and paging stations this switch supports, see the Cambridge Sound range.

Key Features

• AVB-validated switching — qualified for the AVB media network used by Qt X control modules.
• NETGEAR GSM4212PX platform — proven managed-switch hardware supplied under the Cambridge part number 911.1966.900.
• Multi-controller audio sharing — enables paging and music inputs to be distributed across all Qt X controllers in a system.
• PoE support — powers compatible network endpoints such as NPX paging stations from the same switch.
• Single-vendor bill of materials — removes switch compatibility guesswork from masking system commissioning.

Typical Applications

• Multi-floor open offices networking several Qt X controllers
• Healthcare campuses distributing paging and masking building-wide
• Call centers combining zoned masking with networked paging stations
• Law, financial, and government facilities standardizing on validated AV network hardware

Frequently Asked Questions

Why do I need a specific switch for Qt X?
AVB streams require switch hardware that supports the protocol's time synchronization and bandwidth reservation. This model is validated for Qt X media networks, so audio sharing between controllers works as designed.

Can it power my NPX paging stations?
The GSM4212PX platform provides PoE, which supports PoE+ endpoints such as NPX paging stations. Confirm the total PoE budget against your device count with Creation Networks.

Do I need this switch for a single-controller system?
A standalone Qt X controller with local inputs does not require an AVB network. The switch becomes necessary when multiple controllers share audio or when networked NPX paging stations are deployed.

What warranty and support apply?
The switch is supplied through the Cambridge/Biamp channel under part 911.1966.900. Request a quote from Creation Networks for system design, switch configuration, and support.
