EH6922 Russian electronic tube paired with Burr Brown's Thailand produced OPA2604AP, acquired by TI company, is a perfect match: beautiful sound, smooth high-frequency, full mid and low frequency, with strong infectivity, sweet mid frequency, round yet detailed sound, good sound field positioning, very clear hierarchy, strong analytical power, and good musical sense!
1、 Product Introduction:
1. Designed with circuit boards, the internal layout is more reasonable, tidy, and aesthetically pleasing.
The front panel adopts a silver 8mm thick aluminum alloy electroplated wire drawing process panel, a blue power indicator tube, and a unique electronic tube display upper cover grid, which has a higher grade (see the figure below).
2. Advanced sandblasting paint technology, pure aluminum alloy 3mm thick box, high gloss metal knob, and pure aluminum alloy large machine feet.
3. The use of traditional rotary switching switches to control advanced fully sealed switches has a long lifespan.
4. The input signal provides four sets of inputs, three sets of gold-plated RCA and balanced NEUTRIK high-end XLR inputs
5. The output signal provides two sets of outputs, gold-plated RCA and balanced NEUTRIK high-end XLR output.
6. The power cord adopts a three plug socket for easy replacement and upgrading of the power cord.
7. Designed with a power grid filtering and purification circuit, it can filter out clutter interference and DC components in the power grid.
8. We use antique oil immersed capacitors and imported polypropylene capacitors such as WIMA for coupling.
9. The power supply adopts multiple high-end transformers with high performance, high efficiency, no magnetic leakage, no radiation, and no noise.
10. The original imported electronic tube (paired) is used, and the original imported Thai BB company OPA2604AP (paired) is perfectly combined.
11. The pond filter capacitor and adjustable voltage stabilizing filter form a precise filtering circuit with good filtering effect, which suppresses residual noise.
12. The electronic tube filament adopts AC power supply, which is warm, moist, and durable compared to DC power supply, without causing sound hardening. At the same time, it prolongs the lifespan of the electronic tube and ensures the reduction of filament interference; The four sealed transformers achieve digital analog separation, separation of power supply and signal power supply, without mutual interference, so that the background is black and clean without interference.
