The technically sophisticated, built-in features, allow awide range of applications at a competitive price. Further, the design features make theamplifier one of the simplest to configure and install with no internal adjustments or retrofitoptions required. Features include• 220-240Vac (at 50Hz) or 24Vdc power operation• 24Vdc phantom power, providing a means of distributing current throughaudio cables to power microphones and other equipment• volume restoration, restoring volume levels to pre-defined factory or user-defined settings when initiating communications in areas such as paging,public address, two-way radio, intercoms and music distribution systems• volume sensitivity and trim controls for all inputs, allowing adjustment to thelevel of the incoming microphone or line-level signals to match the internaloperating levels of the mixer unit• six inputs, the first five of which are balanced and featureo a ‘universal’ input allowing simple configuration via a slide switcho a switch-selectable, 18Vdc phantom power supplyo a switch-selectable, two-note chime, activated when the input priorityterminal is closedo a remote volume restoration relay able to be operated when the inputpriority terminal is closed• a priority ladder for the first five balanced inputs, whereo input 1 mutes all other inputso inputs 2 to 5 operate on a ‘first-come-first-served’ basiso input 6 has no priority(when ‘no priority’ terminal is closed, all inputs act as mixing inputs)• a switchable VOX and Siren facility on input 1; the tone is generated onclosure of the priority input• two 100V line outputs – ‘Music & Speech’ and ‘Speech Only’ (the ‘Music &Speech’ output is permanently connected, providing output of all amplifiertraffic; the ‘Speech Only’ output is only connected when a priority is closed;this can provide paging only, to areas where music is not desired)• separate bass (±8dB at 100Hz), treble (±8dB at 10kHz) and master volumecontrols, located on the front panel• compact size, taking up only 2U of rack space (the amplifier is supplied with19-inch rack mount ears).
