High-fidelity public address and translating system

This paper describes a combined high-fidelity public address and translating system which was provided for the Inter-American Congress for the Consolidation of Peace, Buenos Aires, and which has since been used with satisfactory results for other important multi-language conferences in S. America during the past 3 years. The system was designed to accomplish 2 purposes: First, to overcome adverse acoustical conditions and permit the voice of the speakers to be heard comfortably at any point in the auditorium, with the absence of "loud-speaker effect" which is generally present when the quality of the system as a whole is inferior, or when the loud-speakers are visible and improperly placed with respect to the person speaking. Second, to enable the delegates to listen to nearly instantaneous translations of the speeches in any 3 of the 4 languages used by the speakers in addressing the assembly.
