笔者选用了目前市面上最具代表性,价格最低的以JRC M2150AD为核心的BBE电路加装板。该加装板的具体应用电路参考《家庭电子》1999年第2期第16页。加装BBE音响板非常简单,只需接入+15V直流电,将此板串接于功放系统的音调电路之后,功放电路之前即可。加装完成之后,高、低音音调旋钮均旋至中点,试听理查德克莱德曼的钢琴曲《星空》,将BBE开关拨至“ON”档。整个乐曲的清晰度大为提高,尤其是中高频段效果更为明显。另
I chose the currently on the market the most representative, the lowest price JRC M2150AD as the core BBE circuit board. The specific application of the circuit board reference “Home Electronics” 1999 the second period Page16. Install BBE audio board is very simple, just access the +15 V DC, this board connected in series with the power amplifier system pitch circuit before the power amplifier circuit can be. After the installation is complete, high and low bass tone knobs are screwed to the midpoint, listen to Richard Clayderman’s piano “Starry Sky”, the BBE switch to “ON” file. The clarity of the entire music greatly improved, especially in the high-frequency band effect is more obvious. another
