Simultaneous interpretation systems for live events

Every seat hears every word.

Sidebar Pro is a professional live interpretation system for conferences, summits, and high-stakes productions. Your interpreter performs from a broadcast-grade console. Your audience listens on the device already in their hand.

Pre-event integration · On-site engineering available · Session recordings delivered next business day

A purpose-built alternative to receiver-based interpretation. Engineered for events where the audio path can't be the weak link.

  • —No receivers to issue, sanitize, or recover. No deposits, no missing units.
  • —Broadcast-grade signal chain end to end — booth monitor mix, lip-sync delay, room PA send.
  • —Multiple language pairs run in parallel without additional channels or transmitters.
  • —A single operator dashboard supervises every active language room in real time.
  • —Full session capture per language, delivered in broadcast format for archive.

What's delivered to your event.

A broadcast-grade interpreter console

Independent monitor faders for stage feed and listener return, configurable lip-sync delay, latching public address, push-to-talk to listeners, and hard cough mute. Your interpreter focuses on the language; the routing handles itself.

Listening on devices your audience already owns

One QR code, one tap, instant audio. No application install, no account creation, no language picker to explain. Compatible with every modern mobile browser on iPhone and Android.

Full session capture, automatically

Three parallel broadcast WAV tracks per language — interpreter mic, stage feed, listener mix — captured natively at every session. Delivered to your team within one business day for archive, compliance, or post-production.

Surfaces problems before your audience does

The console alerts the booth the instant a microphone stops carrying signal, a network path degrades, or a hardware node disappears. Issues are visible to the operator before they become visible to the room.

Pre-event integration with your AV team

Before the doors open, we run a complete dry-run alongside your interpreter and your AV crew — devices configured, latency measured, listener flow validated end-to-end, redundancy path confirmed in writing.

On-site engineering for high-stakes events

For events where the audio path cannot fail, we deploy on-site. A console operator at the dashboard supervises every active language room, every connection, every level meter — ready to intervene before anyone in the audience notices.

The engagement.

A four-stage engagement designed so your team focuses on the program while we own the interpretation infrastructure.

01

Scoping

A short consultation to scope the engagement — language pairs, dates, venue, expected audience, and existing AV infrastructure. We respond with a tailored proposal within one business day.

02

Pre-event integration

A complete technical rehearsal with your interpreter and AV lead. Devices configured, latency measured end-to-end, listener flow validated, redundancy path confirmed in writing.

03

Event day

Your team focuses on the program. Our operator monitors every language room and every connection from the dashboard, ready to act before the audience perceives an issue.

04

Delivery

Session recordings — three broadcast WAV tracks per language — delivered to your team within one business day, ready for archive, compliance review, or post-production.

Engineered to integrate with the infrastructure your AV team already trusts.

Sidebar Pro is hardware-agnostic by design. The console interfaces with the professional audio and video systems your venue already runs — Dante, AES67, SDI, NDI, HDMI — so your engineer keeps full control of the signal chain.

What event teams ask before they engage.

Does the audience need to install anything?
No. The listener experience is a web page that opens in any modern mobile browser. Audience members scan a QR code or open a short link, tap once, and they're listening. No application, no account, no microphone permission.
How many languages can run in parallel?
As many as the program requires. Each language pair runs in its own isolated audio room with a dedicated listener URL — Spanish attendees never hear the German feed, and the German feed never bleeds into the French. Our operator supervises every room from a single dashboard with live level meters and connection-quality indicators.
What end-to-end latency should we expect?
Typically 50–150 ms on our standard cloud relay — comfortable for simultaneous interpretation. For broadcast-critical or sub-30 ms requirements, we deploy a dedicated relay on the venue LAN as part of the engagement.
Do you provide interpreters?
We provide the system, not the linguists. Your event brings qualified interpreters; Sidebar Pro delivers their performance to every seat at broadcast quality. If you need help sourcing interpreters for a specific language pair, we can refer agencies we've worked with.
How does the interpreter's voice reach the room PA?
A dedicated return path sends the interpreter's voice to a Dante channel that your FOH engineer patches into the main PA or a language-specific zone. The console exposes latching public address, a separate push-to-talk to listeners, and hard cough mute — every routing decision is visible at the surface and rehearsed before the event.
What about venue Wi-Fi reliability?
Network validation is part of the pre-event integration. For venues with constrained or restricted networks, we deploy a dedicated relay on a local server so listener traffic never leaves the venue LAN. The path is confirmed in writing before the event opens.
Is the session recorded?
Yes — three parallel tracks per language room (interpreter microphone, stage feed, listener mix) captured as broadcast WAV. Recordings are delivered to your team within one business day. Recording can be disabled for venues that prohibit it; specify during scoping.
Can the same engagement support a hybrid audience?
Yes. The same listener URL serves an attendee in the third row and a stakeholder watching from another country — the audio path is identical. Hybrid and remote-attended events are part of the standard engagement.
How far in advance should we engage?
For a standard event we recommend a minimum of two weeks for scoping, integration, and rehearsal. For complex multilingual productions, four to six weeks is preferable. We accommodate accelerated timelines on a case-by-case basis.
Where is Sidebar Pro currently deployed?
Sidebar Pro is in production deployment for live multilingual events. References available on request, under NDA where required by the engaging organization.
