KUDO offers two primary methods for routing interpretation audio to external sound systems like FM transmitters or infrared (IR) audio distribution systems:

• Option 1: KUDO Audio Manager — Use a single PC to route multiple language channels directly to Dante-enabled systems. Click here to learn more →

• Option 2: KUDO Mobile Link Method (this article) — Use individual laptops per language to route audio via headphone out or audio interfaces.

   

When to Use This Setup

The KUDO Mobile Link allows attendees to listen to live interpretation via their smartphones. However, routing audio to external receivers can be beneficial when:

• Smartphones run low on battery or overheat
• Internet connectivity is unreliable
• You need a backup/compliance solution using traditional receivers (FM or IR)

Equipment Needed

• 1 laptop per language (Windows/macOS)
• Wired internet connection for each laptop
• Google Chrome browser (recommended)
• Optional: USB audio interface for better quality
• 3.5mm to RCA/XLR adapters or cables
• FM transmitter or IR audio distribution system
• Optional: Ground loop isolators to reduce hum/noise, and adapters.

Step-by-Step Setup Guide

1. Laptop & Mobile Link Setup

• Plug in each laptop and connect to reliable internet (Wi-Fi or Ethernet).
• Open Chrome and navigate to the KUDO Mobile Link for your event.
• Join the session as a listener on each laptop, selecting one language per device.
  Example:
  • Laptop 1: Spanish
  • Laptop 2: English
• Confirm that audio is playing through each laptop using headphones or built-in speakers.

2. Route Audio to the External System

Option A: Using Headphone Out (Simple)

• Connect a 3.5mm cable from the laptop headphone jack to your FM or IR transmitter input.
• Adjust laptop volume to around 70% to avoid distortion.
• Use a ground loop isolator if you hear hum or interference.

Option B: Using USB Audio Interface (Recommended)

• Connect a USB audio interface to the laptop.
• Set your system/browser audio to output via the interface.
• Use the interface’s RCA, 1/4", or XLR outputs to feed your transmitter.
• This method offers cleaner, more stable audio quality with less chance of interference.

3. Transmit to Attendee Receivers

• FM Setup: Connect each audio feed to a dedicated FM transmitter.
• IR Setup: Connect each audio feed to an IR emitter panel.
• Ensure attendees are tuned into the correct channels/frequencies.

Tips for Best Results

• Clearly label each laptop by language.
• Use wired internet when available for maximum stability.
• Disable sleep mode, screen savers, and system notifications on all laptops.
• Conduct full audio testing before the event.
• Monitor output during the session.
• Provide extra FM or IR receivers as backups for attendees.
