4. Description

4.1 General

The FC•3 / FC•7 is a 2-way stereo crossover with inte-
PRO PRO
gral 3-band limiter for bass, mid and high frequencies. The full-
range stereo, 2-way stereo and mono-bass modes can be selec-
ted from the back of the unit. There are two potentiometers
located on the front of the unit, which are for adjusting the bass
level to that of the mid-high loudspeaker and for horn correc-
tion.
Internal signal processing is analogue.
There are 16 digital stored subwoofer and mid-high speaker
presets available for configuring the unit to incorporate the
speakers being used. These presets were programmed during
manufacture (see table).
The CAS procedure is used when configuring the controller to
incorporate the amplifiers. The volume and the maximum out-
put power of the amplifiers are measured by an integral com-
puter via a standard speaker cable with 4-pin Speakon connec-
tor.
Measuring is carried out simply by pressing a button before the
speakers are connected to the amplifiers; no previous technical
knowledge is required, no sound is generated and the process
takes no longer than 60 seconds. The measured amplifier data
are calculated in combination with the 32 presets and are sto-
red in an EEPROM. The data is also stored after the power is
switched off and can remain stored for a minimum of 40 years.
The unit does not require a battery to store this data.
Once the measuring process is completed, a sensing line is no
longer required.
LEDs indicate which channels were measured successfully.
