Page 5: Installing And Looking After The Product
Processed Active Speaker Installing and Looking After the Product Connection to the electrical mains Before connecting the device to the mains, make sure that the mains voltage is the same as that marked on the rear panel (max. tolerance ±10%) and that the POWER supply switch is in the off position.
Page 6: Optional
Proteus 180A is an active speaker that combines technology, experience and good taste in the ideal combination of sound quality, power and user-friendliness. The core of the system is a special 10” loudspeaker, realized following the Voice Systems Lab specifications for an excellent reliability and constancy of diffusion.
Page 7: Controls And Connections
Processed Active Speaker Controls and Connections Located on the rear of the device, the control and connector panel is user-friendly and versatile in its connection options. The panel is recessed to protect the trimmers and other components even during transport 1.
Page 8 Processed Active Speaker 6. GND LIFT: ground separator. Press this key to separate the ground of the inputs from that of the internal circuit. In practice, ground separation can be useful for reducing or eliminating the buzzes and disturbance which often occur when several devices are connected together (generally caused by “ground loops”, differentials and interferences between ground references, etc.).
Page 9: Processing And Amplification
Processed Active Speaker Processing and Amplification The Proteus 18A has a signal processing and amplification chain that optimises control of the system PROCESSING The processing chain comprises an initial section for general signal processing, with pass-band filter, high frequency equalisation corrector and level compressor/limiter; the chain is completed by a specific section for each way, with crossover pass-band filters.
Page 10: Guidelines For Use
Processed Active Speaker Guidelines for Use The acoustic characteristics of the room/environment in which a sound system is used have sometimes very significant effects on the overall sound produced. Thanks to its special technical features, using a Proteus 180A some of the most common problems can be reduced or prevented.
