Informazioni

General Applications When used for two-channel bi-amplification, each channel INPUT of the 5235 receives the full-range program signal from a line level source such as a preamplifier, mixing console or graphic equalizer. Identical frequency selection modules are installed in both channels, and the dividing network, separates each of the two channel's signals into high and low frequency bands. Each channel’s LOW and HIGH outputs then feed individual power amplifiers (or discrete amplifier channels), which in turn drive their respective loudspeaker components. The 5235 also may be used as a dividing network for a single channel of triamplification. In this application, Channel 1 of the 5235 receives the full-range program signal, and separates it into two bands, one consisting of low and mid frequencies, the other of high frequencies only. The Channel 1 HIGH output then feeds the amplifier which drives the high frequency driver, while the Channel 1 LOW output (carrying low and mid frequencies) is connected to the 5235's Channel 2 INPUT. The Channel 2 crossover point is chosen to fall in the region where the low frequency loudspeaker's operating range ends and the midrange driver's operating range begins. Therefore, Channel 2's LOW output is suitable for feeding the amplifer which drives the low frequency loudspeaker, while its HIGH output is suitable for feeding the amplifier which drives the midrange driver. In this way, the CHANNEL 2 HIGH FREQUENCY LEVEL control becomes a midrange driver level control and is independent of the CHANNEL 1 HIGH FREQUENCY LEVEL control, which affects only the high frequency driver. As an option, the 5235 can be fitted with "blank" frequency dividing modules that have Jumper resistors installed in such a way that the input signal is split and fed to each channel's HIGH and LOW outputs. As such the 5235 operates as a fully buffered dual distribution amplifier. While this is not the primary purpose of the unit, the capability can be useful when it is necessary to split a signal and drive separate lines and prevent any short or noise source on one line from causing problems on the other.
