AES67 to AES3 Converter Buyer’s Guide 2026 — Latency, PTP & Channel Density
AES67 has won as the open IP-audio interoperability standard. Dante, RAVENNA, Livewire+ and Q-LAN all interchange AES67 streams on a managed network, and every broadcast facility built or refit since 2022 includes AES67 in the design. The remaining engineering question is the bridge to legacy AES3 / XLR balanced infrastructure — and the converter you choose either makes or breaks the rebuild budget.
This guide covers what to look for in 2026, how to map specs to deployment scale, and where SUPERCAN’s 4-channel AES67 to AES3 converter fits relative to broader category tiers.
The Five Specs That Actually Matter
- End-to-end latency — anything above 1 ms breaks live in-ear monitor (IEM) chains, broadcast intercom, and theatre foldback. Marketing sheets often quote one-way latency only; ask for round-trip.
- PTPv2 sync compliance — AES67 mandates IEEE 1588-2008 PTPv2 with a defined profile. Older AES3-clocked converters will free-wheel and drift; this is a real on-air fault.
- Sample rate & bit depth — 48 kHz / 24-bit is the floor for broadcast; 96 kHz / 24-bit is required for high-end music production. Pre-2020 converters often cap at 48 kHz / 20-bit.
- Channel density per RU — 16 channels in 1 RU is the broadcast-truck benchmark; 4–8 channels per box is the install / theatre benchmark.
- Form factor & power — fanless and PoE-powered units survive in stage-box and IT closet installs; rack units with hot-swap PSUs survive in broadcast trucks.
How Deployment Tier Maps to Product Class
| Deployment | Typical channel need | Latency budget | Form factor | Price tier (per unit) |
|---|---|---|---|---|
| Live touring / theatre foldback | 4–8 channels | < 1 ms (IEM-critical) | Fanless half-rack | $100–$2,000 |
| Studio / post-production | 2–8 channels (96 kHz) | ~1 ms | Fanless half-rack | $500–$2,500 |
| Broadcast truck / master control | 16+ channels per RU | < 1 ms, ST 2022-7 redundant | 1 RU rack, redundant PSU | $3,000–$15,000+ |
| Cinema / DCP audio | 32 channels (7.1 + Atmos beds) | not published | 1 RU rack, dual PSU | $5,000+ (cinema OEM) |
Where the SUPERCAN AES67 Converter Fits
The 4-in / 4-out SUPERCAN AES67 to AES3 converter targets the install, theatre, and small-truck deployment tier:
- End-to-end latency < 1 ms — both stages of conversion combined, IEM-safe
- 44.1 / 48 / 96 kHz at 16–24 bit — covers broadcast-floor through music-production ceiling on the same unit
- PTPv2 sync with auto-negotiation against any AES67-aware PTP master on the network
- AES67 native + AES67-mode interop with Dante, RAVENNA, and Livewire+ — the same protocol coverage list as units 10× the price
- Fanless half-rack form factor — survives stage-box vibration and silent install racks
- From $129 — pricing that makes carrying spares affordable, which matters more than channel count on tour
The 4-channel form factor is engineered specifically for the deployments where channel density matters less than per-unit cost: theatre foldback, monitor world IEM chains, intercom routing, small location-recording trucks, and studio post-production rooms.
When to Look Outside the SUPERCAN Range
Two situations call for a higher-density rack unit:
- 16+ channel broadcast trucks needing ST 2022-7 dual-network redundancy and 1 RU density. Pay the broadcast-class premium — the rack-mount converters in this tier are engineered for hot-swap PSUs and dual GigE failover that the install tier does not require.
- Cinema DCP workflows with 32-channel 7.1+Atmos beds. The cinema OEM converters in this class are purpose-built for the SMPTE DCP environment and integrate with cinema-specific timecode and routing protocols.
For everything else — the “I need 4–8 channels of AES67 to AES3 with safe latency and PTP sync at a price that lets me put a spare in the trunk” brief that fits most install and live-sound work — the SUPERCAN unit is the right answer.
Why “Latency Under 1 ms” Is Not Marketing Fluff
Two real-world failure modes drive the <1 ms requirement:
- IEM ear-fatigue — beyond ~3 ms one-way (ear to brain), singers reflexively pull a monitor ear to escape the comb-filter effect. The AES67 hop is one segment of a longer chain (mic preamp + Dante + AES67 + cans), so each box must keep its bite below 1 ms.
- Broadcast intercom round-trip — director ↔ camera op cue exchange degrades if total round-trip exceeds 60 ms. Two AES67 / AES3 conversions plus IP routing plus DSP can easily eat 30 ms if any single bridge is sloppy.
Treat any spec sheet that omits latency entirely as a red flag.
Frequently Asked Questions
Q. Is AES67 the same as Dante?
No. Dante is a proprietary Audinate transport that supports AES67 as an interoperability mode. A native AES67 device can exchange streams with Dante hardware running in AES67 mode, but it cannot use Dante’s native discovery or control protocols. Plan for both if your facility is mixed.
Q. Do I need an AES67-aware network switch?
You need a managed gigabit switch with IGMP snooping and PTPv2 support. Generic unmanaged switches will deliver audio but PTP sync will drift, causing periodic clicks and dropouts.
Q. Can AES67 carry video too?
No. AES67 covers audio only. The companion standards for video are SMPTE ST 2110-20 (video essence) and ST 2110-40 (ancillary data). A facility designed around ST 2110 will use AES67 (or ST 2110-30) for the audio leg.
Q. What’s the difference between AES67 and ST 2110-30?
ST 2110-30 is a profile of AES67 with stricter constraints on stream format (L24, 1 ms packet time, 48 kHz default). Every ST 2110-30 stream is by definition a valid AES67 stream. Most modern converters now advertise both labels.
Q. How do I test the latency of a converter I’m evaluating?
Send a sine wave from a Dante / AES67 source into the converter’s IP input, take the AES3 output to an AES3-capable interface, and measure round-trip in a DAW with a click track. Subtract your AES3 capture interface’s own latency.
Price ranges and channel benchmarks listed reflect general 2026 market observations across the AES67 converter category. Confirm specifications for any unit critical to your application directly with the manufacturer before purchase.
