Interpreter Console

Definition & Overview

An interpreter console (also termed an interpreter desk or unit) is a specialized electronic audio interface positioned inside a soundproof interpretation booth. Governed internationally by ISO 20109 (equipment for interpretation), the console gives interpreters real-time physical control over incoming floor audio, outgoing target language feeds, and communication with audio technicians.

Unlike standard broadcasting mixing desks, an interpreter console is engineered for rapid, error-free physical switching without requiring visual distraction from the speaker and stage.

Core Hardware Functions & Controls

Professional conference consoles (such as Bosch DICENTIS, Shure DCS 6000, or Televic Confidea) incorporate standardized physical controls:

• Microphone Activation (MIC ON / PTT): High-reliability illuminated mechanical buttons that activate the gooseneck condenser microphone. An illuminated red ring on the microphone head signals live transmission.
• Cough Mute Button: A momentary non-latching switch that instantly cuts microphone output while pressed, enabling the interpreter to clear their throat, cough, or consult their booth partner silently without broadcasting noise to listeners.
• Relay Channel Selector (Incoming Routing): Allows the interpreter to toggle between the original plenary floor audio and one or more pivot language channels during relay interpretation.
• Outgoing Channel Keys (A/B/C Routing): Selects which target language channel the interpreter's voice feeds. Channel A represents the interpreter's primary native target language; Channel B is used for retour interpretation.
• Tone & Volume Controls: Independent rotary bass and treble tone-shaping dials, volume knobs, and dual headphone jacks allowing two interpreters seated side-by-side to customize their acoustic feed independently.
• Intercom & Technician Call: A private back-channel circuit allowing booth linguists to alert the chief sound engineer to audio issues, slide changes, or speaker microphone faults without broadcasting over delegate lines.

Acoustic Safety & ISO 20108 Protection

A vital engineering requirement for modern digital interpreter consoles is acoustic shock prevention. In compliance with ISO 20108, professional consoles include internal digital signal processing (DSP) brickwall limiters that clamp sudden acoustic spikes (such as dropped microphones or feedback squeals) below 94 dBA SPL. This hardware protection safeguards interpreters against permanent acoustic trauma and tinnitus. Read our technical guide to acoustic shock prevention.

Hardware Consoles vs Virtual Software Consoles

In Remote Simultaneous Interpreting (RSI) web platforms, physical consoles are sometimes replaced with on-screen virtual software buttons. However, professional conference standards overwhelmingly favor physical hardware consoles for on-site and hybrid events:

• Zero Latency: Physical consoles operate over dedicated uncompressed digital buses (such as Dante, Ravenna, or proprietary shielded daisy-chains) with zero perceptible processing delay.
• Tactile Muscle Memory: Physical switches allow interpreters to mute or switch channels by touch without moving an on-screen mouse cursor during high-speed speeches.
• Hardware Redundancy: Professional consoles operate independently of operating system crashes, browser tab freezing, or computer operating system audio driver updates.
