On-site/Hybrid Meetings

On-site interpreting still depends on physical cables: Sight-Terp Assist needs a direct feed from the Bosch console, while you keep monitoring the floor through your usual headphones.

Option 1 — 3.5mm console headphone output with KYXAIN MOMIX CAB

On-site signal path: interpreter console to laptop The console headphone output runs through a 3.5mm male-to-male cable and a 6.35mm adapter into the KYXAIN MOMIX CAB, which connects to the laptop over USB-C. Your headphones stay plugged into the console, so you keep monitoring the floor as usual. SIGNAL PATH → Interpreter console 3.5 mm headphone out 3.5 mm cable male to male Adapter 3.5 → 6.35 mm MOMIX CAB USB audio interface USB-C cable to your computer Your laptop select MOMIX CAB as the input Your headphones stay plugged into the console YOU STILL MONITOR THE FLOOR
Console headphone output → MOMIX CAB → laptop. Your headphones stay on the console.

Required Equipment:

Connection Steps:

  1. Connect one end of the 3.5mm audio cable to your interpreting console's headphone port (3.5mm)
  2. Connect the other end to the 3.5mm socket on the 6.35mm-to-3.5mm adapter
  3. Plug the adapter's 6.35mm plug into the KYXAIN MOMIX CAB input
  4. Connect the MOMIX CAB to your Mac or PC using the USB-C to USB-C cable
  5. Keep your headphones plugged into the console to monitor the floor while the MOMIX CAB captures the same feed
  6. In Sight-Terp Assist, refresh the device list and select KYXAIN MOMIX CAB as the audio source
Why KYXAIN MOMIX CAB?
  • Designed for live streaming and low-latency digital audio
  • USB-powered and optimized for mobile devices
  • Provides headphone monitoring with volume buttons and signal indicators
  • Mixes mono feeds into stereo without draining your headphones

Option 2 — 6.35mm console jack with an external USB sound card

On-site signal path: console floor input to laptop via USB sound card A 6.35 to 3.5 millimetre adapter goes into the console's floor input, then a 3.5 millimetre male-to-male cable runs to the input jack of a USB sound card, which plugs into the laptop. Your headphones stay connected to the console, so you keep monitoring the floor. SIGNAL PATH → Interpreter console 6.35 mm floor input Adapter 6.35 → 3.5 mm 3.5 mm cable male to male USB sound card 3.5 mm input USB lead to your computer Your laptop select the sound card as the input Your headphones stay plugged into the console YOU STILL MONITOR THE FLOOR
Console floor input → USB sound card → laptop. Your headphones stay on the console.

Required Equipment:

Your headphones stay plugged into the desk for floor monitoring; the USB sound card taps the console’s headphone output in parallel.

Connection Steps:

  1. Plug the 6.35mm-to-3.5mm adapter into the console’s 6.35mm headphone output (the jack carrying the floor channel)
  2. Insert the 3.5mm male-to-male cable into the adapter
  3. Connect the opposite 3.5mm end of the cable to the input jack of the USB sound card
  4. Plug the USB end of the sound card into your Mac or PC (Type-C or USB-A depending on the adapter)
  5. Continue monitoring the floor by keeping your headphones connected directly to the console
  6. In Sight-Terp Assist, refresh the device list and select the new USB sound card as the audio source

Tablet & Phone Notes

Additional adapters:

Tablet/Phone Connection Steps:

  1. Connect the 6.35mm adapter to the console’s 6.35mm headphone output and run the 3.5mm cable to the sound card
  2. Plug the Lightning or Type-C end of the sound card into your tablet or phone
  3. Keep the console's headphone monitoring chain untouched for the floor feed
  4. Open Sight-Terp Assist and pick the same USB sound card as the input source

Online Meetings

For remote interpreting on Zoom, Teams, Webex, or similar platforms, Sight-Terp Assist needs to hear the meeting audio from your computer. A small virtual audio device makes that possible by passing what you are listening to back in as an input.

On macOS, use Sight-Terp Audio — our own driver, below. It sets itself up, needs no restart, and is the option we support directly. On Windows, use VB-Cable (VB-Audio Virtual Cable); install it and restart your computer so the virtual device loads correctly.

Meeting app (speaker) Virtual audio device Your headphones and Sight-Terp Assist input

Important: Only change the speaker/output device in your meeting app. Keep your physical microphone selected in Zoom, Teams, or Webex so others can hear you.

macOS — Sight-Terp Audio Recommended

Sight-Terp Audio is our own audio driver for macOS. The installer creates both devices you need and sets them up for you, so there is no Audio MIDI Setup and no restart. Requires macOS 11 or later.

Meeting app (speaker) Sight-Terp Monitor Your headphones and Sight-Terp Assist input

Step 1: Install Sight-Terp Audio

  1. Download Sight-Terp Audio.pkg.
  2. Open the file and follow the installer. You will be asked for your Mac password, because the driver is installed for everyone who uses the computer.
  3. Sound stops for a second while the audio system restarts, and anything already playing may need to be reopened.
Not during a live assignment: installing briefly interrupts audio on the whole machine. Set it up before your meeting, not during one.
If macOS says the file cannot be opened: right-click the installer and choose Open, then confirm. You may also need to allow it under System Settings › Privacy & Security.

Step 2: Choose Sight-Terp Monitor as your output

Open System Settings › Sound › Output and select Sight-Terp Monitor. This one device sends the meeting audio to your headphones and to Sight-Terp at the same time, which is what lets you hear the speaker while the transcript is produced.

Pick the Monitor, not the Audio: the two sit next to each other in the list. If you choose Sight-Terp Audio as your output you will not hear anything, because that device passes sound to Sight-Terp only.

Step 3: Set your meeting app and Sight-Terp Assist

Application Setting Select this device
Zoom / Teams / Webex Speaker / Output Sight-Terp Monitor
Zoom / Teams / Webex Microphone / Input Your physical headset mic (unchanged)
Sight-Terp Assist Microphone / Input Sight-Terp Audio

In Sight-Terp Assist, open the microphone menu and choose Sight-Terp Audio — it is listed first and marked System sound. Allow microphone access if your browser asks.

Heads up on volume: macOS disables the volume keys and the menu-bar slider while Sight-Terp Monitor is selected. Set your listening level in the meeting app instead.
Going back to your microphone: just pick it again in Sight-Terp's microphone menu, and set your output back to your headphones. Nothing needs uninstalling.
Removing Sight-Terp Audio

Set your output back to your speakers or headphones first, then open Terminal and run:

sudo "/Library/Application Support/Sight-Terp Audio/uninstall.sh"

The Sight-Terp Monitor entry can then be deleted in Audio MIDI Setup: select it and click the – button.

Windows VB-Cable only

This method uses only VB-Cable and the classic Windows Sound Control Panel. No third-party routing apps need to run in the background.

Step 1: Install VB-Cable

  1. Download VB-CABLE from vb-audio.com/Cable and extract the ZIP file.
  2. Run VBCABLE_Setup_x64.exe (64-bit) or VBCABLE_Setup.exe (32-bit) — right-click and select Run as administrator.
  3. Complete the installation, then restart your PC — this step is crucial for Windows to initialize the virtual audio drivers.

Step 2: Route the virtual cable to your headphones

Windows must copy whatever enters the virtual cable and send it to your physical headphones or speakers so you can still hear the meeting.

  1. Right-click the Speaker icon in the system tray (bottom-right) and select Sounds, or press Win + R, type mmsys.cpl, and press Enter to open the classic Sound Control Panel.
  2. Go to the Recording tab.
  3. If CABLE Output is not listed, right-click an empty area and enable Show Disabled Devices and Show Disconnected Devices, then right-click CABLE Output and choose Enable.
  4. Right-click CABLE Output and select Properties.
  5. Open the Listen tab.
  6. Check Listen to this device.
  7. Under Playback through this device, select your physical headphones or speakers.
  8. Click Apply, then OK.

Step 3: Configure Zoom / Teams and Sight-Terp Assist

Application Setting Select this device
Zoom / Teams / Webex Speaker / Output CABLE Input (VB-Audio Virtual Cable)
Zoom / Teams / Webex Microphone / Input Your physical headset mic (unchanged)
Sight-Terp Assist Microphone / Input CABLE Output (VB-Audio Virtual Cable)
  1. In your meeting app, set the speaker/output to CABLE Input (VB-Audio Virtual Cable).
  2. In Sight-Terp Assist, refresh the device list and set the microphone/input to CABLE Output (VB-Audio Virtual Cable). Allow microphone access if your browser prompts you.
  3. Join a test meeting or play sample audio to confirm transcripts appear in Assist while you hear the audio through your headphones.
Tip: If you hear an echo, lower the meeting app volume or the Listen-tab level. Some latency between Listen routing and direct output is normal on Windows.
macOS — VB-Cable Alternative

On Mac, use Audio MIDI Setup to create a Multi-Output Device that sends meeting audio to both your headphones and VB-Cable at the same time.

Step 1: Install VB-Cable

  1. Download VB-CABLE from vb-audio.com/Cable and run the macOS installer.
  2. Approve any System Settings security prompts for the VB-Audio driver (you may need to allow the system extension under Privacy & Security).
  3. Restart your Mac so the virtual cable appears in your audio device list.

Step 2: Create a Multi-Output Device in Audio MIDI Setup

  1. Open Audio MIDI Setup (Applications > Utilities > Audio MIDI Setup, or search with Spotlight).
  2. Click the + button at the bottom-left corner and choose Create Multi-Output Device.
  3. In the device list on the right, check both:
    • Your physical output (e.g. External Headphones or MacBook Pro Speakers)
    • VB-Cable (may also appear as VB-Audio Virtual Cable)
  4. Enable Drift Correction on VB-Cable (clock source should stay on your physical output). This keeps both outputs in sync.
  5. Optionally rename the device (e.g. "Meeting + VB-Cable") by double-clicking its name in the sidebar.
  6. Right-click the Multi-Output Device and choose Use This Device For Sound Output, or set it as the system output in System Settings > Sound > Output.
Heads up on volume: macOS disables the volume keys and the menu-bar slider while a Multi-Output Device is selected. Set your listening level inside Audio MIDI Setup — select the Multi-Output Device and adjust the slider next to your headphones — or keep your meeting app’s own volume control handy. Switch the system output back to your headphones when you are done to get the keys working again.

Step 3: Configure your meeting app and Sight-Terp Assist

Application Setting Select this device
System / Zoom / Teams Output / Speaker Your Multi-Output Device
Zoom / Teams / Webex Microphone / Input Your physical headset mic (unchanged)
Sight-Terp Assist Microphone / Input VB-Cable (VB-Audio Virtual Cable)
  1. Ensure your Mac's system sound output is set to the Multi-Output Device (meeting apps usually follow the system default).
  2. In Sight-Terp Assist, refresh the device list and select VB-Cable as the input source. Allow microphone access if your browser prompts you.
  3. Play test audio or join a brief meeting to verify you hear participants in your headphones while Assist transcribes the same feed.
Note: If VB-Cable does not appear after installation, open System Settings > Privacy & Security, allow the VB-Audio system extension, and restart again.
Alternative: hardware capture path (TRS splitter)

If virtual routing is not available on your machine, you can capture meeting audio with a physical TRS splitter and USB adapter instead of VB-Cable.

TRS splitter + USB adapter:

  1. Plug the male jack of a TRS splitter into your computer's headphone output port.
  2. Plug your headphones into one of the TRS splitter's female ports so you can continue monitoring.
  3. Connect the other female port to a TRS audio cable.
  4. Plug the other end of the TRS audio cable into the microphone port of a USB adapter.
  5. Insert the USB adapter into your computer's USB port.
  6. In Sight-Terp Assist, select the USB adapter as the audio input source (refresh your device list if needed).
  7. Verify that your headphones and microphone still work correctly in your video conferencing software.
Set the level before you rely on it: a headphone output is far hotter than a microphone input expects. Start with your computer volume at roughly 20-30% and raise it only until Assist reads the audio clearly — running it wide open clips the signal and costs you transcription accuracy. Most built-in mic inputs are mono as well, so expect one mixed channel rather than stereo. Where you can install VB-Cable, the virtual route above avoids both issues.

Troubleshooting

Common Issues and Solutions

No Audio Detected

  • Check all cable connections are secure (on-site setups)
  • Verify the correct audio source is selected in Sight-Terp Assist and refresh the device list
  • For online meetings: confirm VB-Cable is installed and you restarted after installation
  • Test audio output from your interpreting console or play a test tone in your meeting app

Online Meetings (VB-Cable)

  • CABLE Output not visible (Windows): In Sound Control Panel > Recording, enable Show Disabled Devices, then enable CABLE Output
  • No transcript in Assist: Meeting speaker must be CABLE Input (Windows) or system Multi-Output Device (Mac); Assist input must be CABLE Output / VB-Cable
  • Can't hear the meeting: Windows — check Listen tab on CABLE Output; Mac — confirm headphones are checked in the Multi-Output Device
  • Echo or double audio: Lower meeting volume; on Windows, reduce the Listen-tab level
  • Browser blocked mic: Allow microphone permission for sightterp.net in your browser site settings

Low Volume After Connection

  • This is normal when splitting an audio signal across two paths
  • Turn up volume on your console or meeting app
  • Ask the technician to increase volume from the stage audio mixer (on-site)

Audio Quality Issues

  • Check for loose connections
  • Try different audio cables
  • Ensure proper grounding on external USB sound cards and interfaces
  • Check for interference from other devices

Software Issues

  • Restart Sight-Terp Assist
  • Refresh the webpage if using the browser version
  • Reboot your device after installing audio drivers or VB-Cable
  • Check system audio and microphone permissions
  • Update audio drivers
