DESCRIPTION

C5212-96 belongs to RCF ACUSTICA - NEW COMPACT SERIES and is a
full range extremely versatile wide-dispersion, two-way loudspeaker system
offering substantial power and efficiency for several professional applications
that include main sound systems for permanent installations, plus portable
systems and supplementary fill for larger systems.

RCF exclusive ‘Constant Matching Design’ technology helps guarantee an
optimal transition between the high frequency horn polar pattern and the low
frequency woofer directivity.
The horn can be rotated, allowing to install the loudspeaker either vertically or
horizontally.
The hi-frequency transducer is a 1.4” RCF PRECISION compression driver with
a 2.5” voice coil.
The low-frequency transducer is a 12” RCF PRECISION woofer with a 3” voice
coil.

The system includes a high-level crossover network that features markedly
lower (than conventional) induction values in series with the woofer. This
innovation is named LICC (‘Low Impedance Compensated Crossover’: its
benefits are delay reduction, reduced phase shift and superior transient
response.
Dynamic high-frequency driver protection is accomplished with a new RCF
exclusive - ‘Active Mosfet Compression Driver Protection System’ (AMCDP),
chosen to complement the driver power curve.
The internal crossover can be easily bypassed for bi-amplification.

The cabinet is made of Baltic birch (heavy duty painted) and allow different
installation options, as it is equipped with top and bottom ‘Multiplates’ for
either wall or suspended mounting with chains.
Installation points are available on its rear panel as well.
The steel front grille is protected with a double layer polyurethane fabric.
The front RCF logo is easily rotatable.

Connections are made through two Neutrik Speakon NL4 connectors (audio
input and parallel link
output).
