Beschreibung: Electronic Frequency Dividing Network
                                    The 5231 and 5232 Electronic Frequency Dividing Networks are
designed for use with studio monitor or sound reinforcement
loudspeaker systems where bi-amplification or
triamplification is desirable. The use of electronic
frequency dividing networks and multiple amplifiers results
in a cleaner signal being fed from the power source directly
to the individual loudspeakers of the system. By dividing
the audio spectrum before power amplification, treble tones
are separated from, and unaffected by, Bass frequencies. The
result is more efficient utilization of available Amplifier
power. For example, a system consisting of 100-Watt low
frequency and 50-Watt high frequency amplifiers will provide
the same low distortion performance as would a single
300-Watt Amplifier driving the loudspeaker system through a
conventional passive frequency dividing network. Direct
coupling to the loudspeakers eliminates the insertion loss
typical of most passive networks and also permits
realization of the maximum damping factor available from a
given Amplifier.

Model 5231, single channel, provides the electronic
transition for one bi-amplified loudspeaker system. The
5232. a dualchannel unit, can be used for bi-amplification
of two loudspeaker systems or to control both transition
points in a triamplified system. The latter can be
accomplished by utilizing one channel for the lower
Crossover frequency and the other channel for the high
frequency transition.

Performance and operational characteristics of the two
models are identical; they are maximally flat second-order
electronic Crossover networks utilizing active filters. They
exhibit unity gain in the pass band, provide adequate output
to drive any quality Amplifier and operate at extremely low
distortion levels at full rated output. The Crossover
frequency is determined by inserting the proper printed
circuit card into each channel’s circuitry. Inserts are
available for the following Crossover frequencies: 250 Hz,
500 Hz, 800 Hz, 1200 Hz and 5 kHz. A blank card is also
available for construction of circuitry to provide alternate
Crossover points. Each channel is provided with a level
control for high frequency shelving.
