Interpreting booths are used wherever people meet and want to communicate across language barriers. Even though English is the colloquial language at most international congresses and conferences in Essen: If there are really important matters or detailed questions to be clarified, the services of simultaneous or conference interpreters are still used. Interpreters and the appropriate interpreting booths are used at multilingual congresses in Essen as well as at international specialist conferences, shareholders' meetings, EU works council meetings, board meetings or corporate events. Popular venues in Essen for this include Messe Essen, the Congress Center Essen or the various locations in the Zollverein Coal Mine Industrial Complex.

PCS supplies the organizers of multilingual conferences and meetings in Dortmund with interpreter and language booths from its headquarters in Düsseldorf. For the rental of interpreter booths, PCS relies on the Silent 9300 series from the Dutch brand manufacturer Audipack, which is now the industry standard. This also has the advantage for customers that the interpreter booths are compatible with all standard interpreting systems.
