Description:
- The FM 255 is a new products made by weiliang audio and breeze audio ,before we have made FM155 preamplifer and FM300A FM711 power Amplifier This time we use the same method to crack the core circuit (black box). It was very successful and the sound quality was very good.But we can only think that we have succeeded 98% because there is still a problem that needs improvement. There is a slight low noise, although there will be no effect when playing music. We will continue to improve. Because we are a manufacturer, we dare to say our shortcomings. We also have the ability to change, even if it takes a long time.
- This preamplifier has two sets of balanced XLR, three sets of RCA single-ended inputs, one set of single-ended RCA tape inputs, one set of single-ended RCA tape outputs, and one set of balanced outputs (note that this pre-power amplifier does not have single-ended RCA output function, balanced seat wiring standard European standard).
- Panel Functions Introduction The 5 buttons from the left are 2 sets of balanced XLR and 3 sets of single-ended RCA input switching, phase reversal, monaural monitor, tape channel, attenuation 20dB function, left and right channel volume balance adjustment knobs, total volume Control knob
- Internal components We try to use the same as the original factory, but because some of the components are no longer found, we will use the same quality replacement. We will also constantly improve internal components. So when the goods you received are different from the components on the map, it means that the upgrade has been improved. If you can't understand this, please think clearly and then buy it.
