For simultaneous interpretation (SI), you need a range of specialized equipment to ensure smooth communication across different languages. Here's a breakdown of the essential equipment:

For the Interpreters:

• Soundproof Interpreter Booths: These are crucial for isolating the interpreters from the noise of the conference and ensuring their voices are transmitted clearly without interference. They typically have:
  • Soundproof walls and glass: To minimize sound leakage.
  • Ventilation system: For comfort during long sessions.
  • Lighting: Adequate for reading notes and operating equipment.
  • Tabletop space: For consoles, laptops, and notes.
• Interpreter Consoles: These are the central control units for the interpreters. They usually feature:
  • Headphone jacks: For monitoring the floor language and their own interpretation.
  • Microphone with a mute button: For clear audio transmission and temporary silencing.
  • Channel selectors: Allowing interpreters to listen to the original speaker's language feed.
  • Output channel selection: To broadcast their interpretation to specific language channels.
  • Volume controls: For adjusting the incoming and outgoing audio levels.
  • Relay function: In some setups, interpreters might listen to another interpreter's output and interpret from that language.
• High-Quality Headphones: Essential for clear and accurate monitoring of the speaker's voice. They should be comfortable for extended use.
• Microphones: Typically gooseneck microphones that allow for flexible positioning.

For the Audience:

• Wireless Receivers: Each audience member needing interpretation receives a personal receiver.
• Headsets: Lightweight headphones that plug into the receivers, allowing them to listen to the interpretation in their chosen language.
• Language Channel Selectors (on the receiver): Users can easily switch between the available language channels.

For the Technical Setup and Management:

• Central Control Unit/Transmitter: This unit manages the audio feeds from the interpreters and broadcasts them wirelessly to the audience receivers on different channels.
• Cables and Connectors: For linking microphones, consoles, and the central unit.
• Technician Support: A skilled technician is crucial for setting up, monitoring, and troubleshooting the equipment during the event. They manage audio levels, ensure clear transmission, and address any technical issues that may arise.
• Distribution System: For larger events, signal splitters and amplifiers might be needed to ensure consistent audio quality throughout the venue.
• Testing Equipment: To check the functionality of all components before and during the event.
