These systems are the culmination of EV's 75 years of experience in transducer design and over 50 years of experience in designing and building electronics. Please take time to consult this manual so that you can understand all the features built into your EV systems and fully utilize all their performance capabilities. Electro-Voice Plasma® Owner's Manual 2 Safety First When setting up, installing and using Electro-Voice Plasma® speaker systems, there are a number of precautions that you should follow: · When Electro-Voice Plasma® speakers are used for portable applications in which they will be stacked directly on the floor, make sure that the floor or stage is solid and secure. Make sure to: · Route cables and position the stand so that performers, production crew and audience members will not trip over the stand or cables and pull the speaker system over. Secure cables with wire ties or tape whenever possible. · If you intend to hang or fly the Plasma two-way systems, only do so safely with the correct hardware and accessories. WARNING: Suspending any object is potentially dangerous and should only be attempted by individuals who have a thorough knowledge of the techniques and regulations of rigging objects overhead. Electro-Voice® strongly recommends that Plasma speakers be suspended taking into account all current national, federal, state and local regulations. It is the responsibility of the installer to ensure that Plasma speakers are safely installed in accordance with all such regulations. If Plasma speakers are suspended, Electro-Voice® strongly recommends that the system be inspected at least once a year. Turn on the power switch and ensure that the system is receiving power by monitoring the status LED. If the system is receiving signal, the LED will illuminate green. Electro-Voice Plasma® Owner's Manual 4 P1 and 1828T Amplifiers Input Signal Electronically balanced inputs for the connection of high-level signal sources such as mixers, signal processors, etc. Establishing the connection is possible via phone or XLR-type jacks. Balanced connection is recommended to prevent noise or HF-interference. Caution: Before connecting or disconnecting any plugs, make sure to set the level control to its counterclockwise stop, which prevents the system, the audience and yourself from being stressed by nasty contact noise. Input Loop Output is full bandwidth pass through. Crossover Mode Switch Selects between 40 Hz highpass filter for Fullrange use, and 100 Hz highpass filter for use with Plasma 1828T subwoofer.
