Crossover

Typical FRi Input Panel
All FRi full range enclosures feature very high
quality barrier strip input terminations for ease
of installation and secure connections.
The active crossover centerpoint is 1600 Hz
with a crossover type of 4th-order (24 dB/oct)
Linkwitz-Riley, recommended.
The full range active crossover should be set for 1600 Hz;
however, if adjustments are made or variations are
implemented do not use frequencies below 1480 Hz!
Crossover slope should be 24 dB/octave. Should budget
allowances permit, limiters may prove a useful and an
appropriate addition to the signal path, especially for the
high frequency section. For more rudimentary clusters we
recommend the EV EX23 Active Crossover which contains
a 4th-order (24 dB/oct) Linkwitz-Riley and a stereo two-way
section with continuously variable crossover frequencies
from 80 - 8000 Hz. Each of the two outputs per channel
has separate mute switches and level controls. For
bi-amping the FRi Series in more complex array
configurations with delays and a greater need for
equalization, we recommend the EV Dx38 Digital Sound
System Controller, which incorporates all necessary
crossover, parametric EQ, shelving EQ, low- and high-
pass filters, alignment (delay), compressor and limiter
functions. (Settings for the Dx38 are available on the
EV Web site: www.electrovoice.com.)
