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.
