EV has coordinated with ATM Flyware and Polar Focus
in developing pre-designed flying hardware to support
the most common array configurations of one sub
flanked by two full-range loudspeakers. To receive

Amplifier Recommendations

Amplifier Recommendations
The EV CPS-2, two-channel power amplifier is recommended
for use with all FRi series loudspeakers, whether running
in passive or active crossover mode. This amplifier is
sufficient to operate up to two paralleled FRi series
cabinets per channel, supplying the necessary headroom
to provide appropriate long term program and instantaneous
peak power for most program materials. If array
configurations are designed as such to run in all passive
mode with more than two cabinets, an amplifier sufficient
to drive the total load requirements of the configuration
must be selected taking into consideration the individual
cabinet power requirements. For example, a 3 box array
containing two full range and one sub can be operated
in bi-amp mode with one channel of the CPS2 handling
the high frequency output of the crossover and feeding
the two full range cabinets and the other channel handling
the low frequency output of the crossover and feeding
the sub(s).
