Electronic Crossover - Electro-Voice FRi+ 181S User Manual

Setting the

Electronic Crossover

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.)
All FRi full range enclosures feature very high
quality barrier strip input terminations for ease
of installation and secure connections.
