Both the Q-SYS NV-32-H and the Crestron DM-NVX line transport 4K60 4:4:4 video over standard Gigabit Ethernet, but their bandwidth profiles differ enough to matter at scale: the Q-SYS NV-32-H Network Video Endpoint can consume up to 800 Mbps per encoder depending on its bitrate setting, while Crestron's DM-NVX defaults to a recommended 750 Mbps and can be fixed anywhere from 200 to 950 Mbps, with 350 Mbps as the practical minimum for genuine 4K60. Neither system runs on an unmanaged switch. Both require proper multicast configuration, IGMP snooping and PIM-SM on the Q-SYS side, a fully nonblocking network fabric on the Crestron side, which is why the actual constraint on a multi-room AV-over-IP deployment is almost always the switching infrastructure, not the encoders and decoders themselves. Trianze specifies the switch fabric and multicast configuration alongside the encoder platform on every corporate rollout, since a technically correct single-room installation often fails to scale once a second or third boardroom joins the same network without this planning done up front.
Bandwidth Per Stream: Q-SYS vs. Crestron NVX
The Q-SYS NV-32-H's bitrate range runs from 10 Mbps up to 800 Mbps per encoder, while Crestron's DM-NVX CBR setting spans 200 to 950 Mbps, with both systems recommending a value close to the top of that range for true 4K60 4:4:4 with minimal compression artifacts.
Per Q-SYS's own NV-32-H documentation, every additional 4K60 source on either system adds roughly 750-800 Mbps of sustained traffic to the network, which is a meaningful fraction of a single 1GbE link's total capacity. A boardroom with two or three simultaneous 4K sources, a room camera, a laptop input, and a content share, can saturate a single Gigabit uplink on its own before accounting for any other traffic on that switch. This is the specific gap Trianze's boardroom design process checks first: how many simultaneous 4K60 streams a room actually needs, not just how many endpoints are being installed.
Multicast Routing: Why It Matters More at Scale Than Per-Room
A single-room AV-over-IP install rarely stresses a network, but a campus rolling out AV-over-IP across 10 or more boardrooms needs multicast routing configured correctly from day one, or streams start colliding on shared switch backplanes.
Q-SYS's NV-32-H supports creating a multicast stream of 4K60 4:4:4 that many decoders can subscribe to simultaneously, which is efficient for distributing the same source to multiple displays but requires IGMP snooping enabled on every switch in the path so multicast traffic doesn't flood ports that never asked for it. Crestron's DM-NVX ecosystem has the equivalent requirement built around its own multicast addressing scheme. Both approaches need a managed switch fabric with multicast support as a hard prerequisite, not an optional upgrade, for any deployment beyond a single room. Our Enterprise IT Infrastructure practice audits existing switch fabric against these requirements before specifying either platform for a multi-room rollout.
1G vs. 10G: When the Uplink Becomes the Real Bottleneck
A single Gigabit Ethernet port handles one 4K60 stream comfortably on either platform, but the switch's uplink to the core network needs 10G capacity once more than a handful of simultaneous streams are aggregating through it.
| Deployment size |
Typical uplink need |
Key consideration |
| 1-3 rooms, single streams |
1GbE per endpoint sufficient |
Standard nonblocking managed switch |
| 4-10 rooms, mixed sources |
10G uplink recommended |
IGMP snooping/PIM-SM mandatory |
| 10+ rooms, campus rollout |
10G+ core, dedicated AV VLAN |
QoS prioritization, switch stacking |
Underestimating uplink capacity is the most common reason a technically correct single-room AV-over-IP install doesn't scale cleanly to a full campus deployment. Trianze specifies switch infrastructure alongside the AV-over-IP platform itself, not as a separate IT project handed off after the encoders are already ordered.

Frequently Asked Questions
How much bandwidth does 4K60 AV-over-IP actually use?
The Q-SYS NV-32-H uses up to 800 Mbps per encoder, and Crestron's DM-NVX defaults to 750 Mbps with a 350-950 Mbps adjustable range. Both figures are close to the practical limit of a single Gigabit Ethernet link, so multiple simultaneous streams need real network capacity planning.
Do I need a special network switch for Q-SYS or Crestron NVX?
Yes. Both platforms require a managed switch with multicast support, IGMP snooping and PIM-SM for Q-SYS, a nonblocking fabric for Crestron NVX. An unmanaged switch will not handle multicast AV-over-IP traffic correctly at any scale beyond a single point-to-point connection.
When do I need a 10G network uplink instead of 1G?
Once a deployment exceeds roughly 3-4 simultaneous 4K60 streams aggregating through one switch, a 1GbE uplink starts running out of headroom. Campus-scale rollouts across 10 or more rooms should plan for 10G core connectivity from the start.
Is Q-SYS or Crestron NVX better for a multi-room boardroom rollout?
Both handle 4K60 4:4:4 over standard Gigabit Ethernet with comparable bandwidth profiles. The deciding factor is usually the broader control and audio DSP ecosystem each platform brings, not a meaningful difference in video bandwidth efficiency between the two.
Does Trianze Tech design the network infrastructure alongside the AV-over-IP system?
Yes. Trianze audits existing switch fabric, multicast configuration, and uplink capacity as part of any Q-SYS or Crestron NVX deployment, rather than treating network readiness as a separate project from the AV install. This includes confirming IGMP snooping, PIM-SM, and nonblocking fabric requirements are met before any encoder or decoder hardware ships to site.
