CIRCUIT DESCRIPTION The TA-D900 is an electronic crossover network designed for use in multi-amplifier stereo systems. The input audio signal is divided into a

44、 number of different frequency bands, each band being amplified independently and passed on to individual speakers. See Fig.3 for an outline of the circuit diagram. Each set of crossover frequency filters have been incorporated into separate plug-in type units. Suitable crossover frequencies for a w

45、ide range of speakers available on the market may be set by plugging in an appropriate combination of the 4 different units. The crossover frequency of each unit is de- termined by the capacitance of the filters, and the frequency selector switches S1-S4. For 2-way to 4-way multi-amplifier systems,

46、the crossover fre- quencies are set by adjusting Sl-S4, and by re- arranging the filter units in accordance with the crossover frequencies of the speakers employed. Levels are also adjusted to match the efficiency of each speaker. Note that the following description refers to a 4-way multi-amplifier

In addition, a current-mirror loaded 2-stage differential amplifier structure reduces distortion to a very low level. Furthermore, in order to make the low channel amplifier a pure DC amplifier em

48、ploying no coupling capacitors, a dual FET differential amplifier which suppresses DC drift has been used in the first stage (Ql0l). Dual transistors have also been used in the second stage differential amplifier (Q103) and current mirror (Q105) to further suppress DC drift. By connecting the base o

49、f Ql04 to ground, the collector voltage of the PNP transistor on the left hand side of Ql03 is reduced to almost 0V, thereby equalizing the collector voltage of both PNP transistors in Q103. The dual transistor Pc (power input dc to collector) are therefore very much the same, resulting in the amount of drift in both sides being balanced. The impedanceconverted signal is then passed from the pre-buffer amplifier to CHI-CH4 where it is divided into 4 different frequency bands. 2. LOW Channel Stage (CH-l) The low-pass
