TYPICAL “BI-AMPED” SYSTEM USING
PASSIVE CROSSOVERS
0.16mH INDUCTOR
(NOT INCLUDED)
SYSTEM DESIGN - PASSIVE / ACTIVE
The Cicada Audio CH COAX HORN comes with a special
12dB per octave crossover. It is HIGHLYrecommended
that this be used at ALL times - UNLESS you are using
an active crosssover set at above 4kHz. Like our
DSP125.4D amplifier or our DSP88 stand alonee processor
with amplifiers. This system, shown is “Bi-Amped”, but not
‘Fully” active. FRONT channels of this 4 channel amplifier
are driving the mid bass drivers. REAR channel are
driving the tweeters. The MIDBASS is shown with a
0.16mH inductor (not included) in series to cross
over the midbass at 4Khz with a 6dB roll-off.
NOTE: This setup makes it easier to adjust
level of the midbass versus the tweeter
by simply adjusting the levels of each
channnel. Piece of cake!!!
TYPICAL “FULLY ACTIVE” SYSTEM
CH series COAX HORN drivers can be “Bi-Amped” Or what is
commonly called FULLY active system setup. In the system shown
- the tweeter(s) are wired to the FRONT channels and the MIDBASS
driver section is wired to the rear channels. At this point you should
seriously think about purchasing a DSP processor - unless your
amplifier has a HP filter that can go to 4Khz, like our CIcada DSP125.4D
DSP Amplifier. (which has infinite filter and slope configurations!!)
Using a DSP amp/processor (or DSP processor and any amplifier)
makes it much easier to control and tune your system.
We recommend using our amplifier with built
in DSP (DSP125.4D)or a stand alone DSP like
our DSP88 Small 8 in 8 out, simple to use....and
controlled by your SmartPhone..or PC.
