68W+68W 5534 independent op amp amplifier finished board with heatsink
LM3886 amplifier chip must use a heat sink, a 3886 chip set manufacturers 50ma static power, there is a certain temperature, it is such an important LM3886 sound better than one reason many similar amplifier chip, even more than many discrete tube line to be good, this subsection plate with a pair of bookshelf box respectively 120 watt 8-inch inside without pressure.
Power supply voltage: 15V allowable range between double to double 28V (referring to the transformer output voltage, such as 25-0-25)
board size: 155mm * 80mm
load impedance: 4-8Ω
Output Power: Max 68W + 68W
Japanese imports JRC5534DD with two double Jiang Sheng op amp amplification level as before, there is no need to spend extra money to add pre-board, amplifier board Taobao part without the previous stage on the need to spend additional hundred or so plus preamp amplifier board in order to play its due effect and power, but this one costs but also put a lot of space, we ha of integration, a one-channel amplifier, the separation is very good, sweet bass voice there is strength! Op amp supporting Sunplus gilded seat, very easy to upgrade, at no changes can be directly under the transducer numerous single-channel operational amplifier chip, such as our common OPA627, OPA604, etc., ground strict design refuses to sound loop current, the output of two Back to the midpoint of independent power strip ground, to have this purely non-transfected lines, not one more element fancy never delete a necessary element.
This section uses a DC servo plate line, eliminating the negative feedback capacitance floor, this capacitance is very large impact on the sound, designed to make work in pure DC 3886 magnification mode, the sound is very natural and transparent, there is what was asked DC servo effect? When the LM3886 canceled after landing a negative feedback output capacitance midpoint of zero drift is not prone to the phenomenon, adding servo circuit perfect solution to give the effect of other lines can not match.
PCB Immersion Gold board using military technology, PCB beautifully seductive, mainly welding easier, enhance current signal transmission performance.
imported Fairchild LM317 / LM337 voltage high current low resistance line, combined with the highest level of KZ Nichicon Nichicon audio capacitors pre-filtered power supply voltage, the sound quality of that foundation every detail.
C1237 speaker protection circuit, genuine Omron relays, power-on delay of about three seconds pull, pull before there will be music sounded, immediately shut off, no sound of impact protection DC ± 1.4v trigger off the output, the guardian expensive speakers.
