1. Overview

Linguabox controls one interpretation cabin: a floor/source feed and two interpreters (A and B) tag-teaming the same booth. It's a single window with two views you switch between — the Operator Console, where devices, routing, and distribution are configured, and the Interpreter Desk, the day-to-day screen interpreters actually work from during a session.

Listeners never install anything — they connect over Wi-Fi from their phone's own browser and pick their language.

2. Installation & Activation

System Requirements

Installing

  1. Download Linguabox-Setup.exe from the Linguabox product page.
  2. Run the installer. Windows may show a SmartScreen warning — click More info → Run anyway to proceed.
  3. Follow the installer prompts. Linguabox installs to Program Files\CueCongress\Linguabox by default.
  4. Launch Linguabox from the Start menu or desktop shortcut.

License Activation

  1. On first launch, the license activation window appears. Enter your license key and click Activate.
  2. Linguabox connects to the CueCongress license server to verify your key. An internet connection is required for the first activation.
  3. Once activated, the app works offline for up to 7 days between checks. Your license is tied to the current device.

Deactivating (Moving to Another Device)

Click the CueCongress logo in the top-right corner to open the About dialog, then click Deactivate This Device. This frees the license so you can activate on a different machine.

3. Interface Overview

Every screen shares one header: branding, a system online/offline indicator, an on-air/standby indicator, an alert-active indicator when an emergency alert is live, and a button that switches between the two views.

Interpreter Desk

Shows both interpreter columns side by side — mic level, the language-switch toggle, floor/relay buttons, personal monitor mix knobs, and a shared Hand Over button between them.

4. Audio Setup

Assigning Inputs

  1. Switch to the Operator Console.
  2. In the Audio panel's Audio Inputs section, pick a device for Floor, Interpreter A, and Interpreter B from their dropdowns.
  3. Click Start Capture.

Every device picker lists None at the top to leave a channel unassigned, and shows one entry per physical device rather than duplicating the same interface across Windows' different audio drivers.

Gain, Low Cut & High Cut

Each input has a gain slider (0 to +18dB) for boosting a quiet mic, plus LC (low cut) and HC (high cut) toggle buttons on its channel strip to remove rumble or tame hiss.

Monitor Out

Assign an output device per booth so each interpreter hears their own personal mix, then click Start Monitor. Bass, treble, volume, and gain for each booth's mix are set from the Interpreter Desk's knobs.

Tip: If a mic and its monitor headset are the same physical USB device, that's fully supported — capture and playback are buffered independently so they don't drift against each other.

5. Interpreter Desk & Handover

Interpreters A and B are paired automatically. Only one of them is on-air at a time; the other is standing by.

Handing Over

  1. Click the shared Hand Over button between the two columns, or press Space (disabled while typing in a text field, so it never fires by accident).
  2. On-air status flips immediately to the other interpreter.

A quiet "on duty" timer nudges a swap around 25 minutes and flags it more visibly past 35 — a reminder, not a lockout.

Floor vs. Relay

Each interpreter has an F (Floor) and R (Relay) button. Floor means listening to the original speaker; Relay means listening to the other interpreter's channel instead — used when interpreting from someone else's translation. The Relay button is labeled with the other interpreter's actual name.

6. Bidirectional Language Output

Linguabox has two independent language output slots. Whichever one is currently targeted receives the live on-air audio; the other stays silent until it's targeted.

Switching Languages

  1. On the Interpreter Desk, click the large language toggle above either interpreter column.
  2. Both the Wi-Fi stream and any hardware Language Output follow the switch instantly.

Listeners already connected to the language that just went silent see a brief "Switching…" notice instead of dead air with no explanation.

Naming Each Language

Set each language's display name from the Operator Console's Language Output section — this is what appears on the listener page's language buttons.

7. Wi-Fi Distribution

  1. Make sure the machine running Linguabox is on the venue's Wi-Fi network.
  2. In the Video · Streaming panel, click Start Streaming.
  3. Share the displayed URL or QR code with listeners — they open it in any phone browser, no app required, and tap their language.
Note: The URL is tied to the current network's IP address. If you switch networks before the event, reopen the panel to get the updated URL and QR code.
Tip: For larger audiences, don't rely on generic venue Wi-Fi — bring your own professional router with a dedicated local network for Linguabox. It gives you far more reliable capacity and range than shared venue Wi-Fi, which is usually the deciding factor in how many participants can actually connect at once.

8. Multi-Cabin Setup

Running interpretation into more than one language at once from separate cabins? Start Linguabox and Wi-Fi Distribution on each cabin's laptop, on the same network. Each cabin discovers the others automatically — no server or manual configuration — and listeners see every cabin's languages as buttons on one shared page.

Tip: A standard license activates on 2 devices, so a standard purchase supports up to 2 cabins running at once.

9. Video on the Desk

In the Operator Console's Video · Streaming panel, choose a camera or capture card from the Video Input dropdown and click Start Video. The live feed appears on the Interpreter Desk, giving a remote or visually isolated cabin context on the room or the presenter's slides.

10. Recording & Emergency Alerts

Recording

Click Start Recording in the Audio panel to save the on-air interpreted audio to a WAV file. Recording runs independently of Wi-Fi streaming — it works whether or not any listener is connected. Choose the save folder from the same section.

Emergency / Technical Alert

Type a message in the Alert field and click Send Alert to push it to every connected listener's screen immediately — for evacuation notices or urgent technical announcements. Click Clear to dismiss it.

11. Troubleshooting

An interpreter's mic sounds jittery or robotic

Device picker shows duplicate entries

Listener can't connect

License activation fails
