CHUBAN MP700 Fully Balanced High-Fidelity Preamplifier, HiFi Audiophile Class A Audio Amplifier for Home Use with Remote Control

MP700 is equipped with a new cast aluminum alloy shell and adopts a fully balanced design with fully independent left and right channels. It is composed of four modules. Compared with ordinary amplification technology, it has the advantages of good symmetry, low distortion, high stability, and strong driving force. The only difference is that it has very strict requirements on the matching accuracy of circuit components. The selection of parts used will be twice that of single-ended circuits. Therefore, it is mostly used in high-end audio equipment.

1. Product Introduction:
1. Designed with circuit board, the internal layout is more reasonable, neat and beautiful.
The front panel adopts 8mm thick aluminum alloy electroplating brushed panel, the upper cover plate grid, high grade and taste.
2. High-grade sandblasting paint thin steel plate box, solid metal knob, pure aluminum alloy large machine foot.
3. Use the coding switch digital mode to control the input selection to ensure no interference and high accuracy.
4. The input signal provides four sets of inputs, two sets of input gold-plated RCA and two sets of balanced XLR.
5. The output signal provides five sets of outputs, two sets of output gold-plated RCA and two sets of balanced XLR, and one set of 4-way RCA output.
6. The power supply line adopts a three-plug socket, which is convenient for replacing and upgrading the power cord.
7. The power grid filter purification circuit is designed to filter out the clutter interference and DC components in the power grid.
8. ELNA, WIMA and other audiophile audio capacitors are used.
9. The power supply adopts multiple high-performance, high-efficiency, no leakage, no radiation, and no noise high-end transformers.
10. Use original imported transistors, chip master control IC and other fever accessories.
11. The water pond filter capacitor plus adjustable voltage stabilization filter constitutes an accurate filter circuit with good filtering effect, which suppresses residual noise.

(1) Power transformation: Both are completely independent on the left and right, and are independently supplied by four module power systems.
(2) Signal filtering: Independent audio-grade filter capacitor circuit to ensure pure power supply capability.
(3) Internal circuit: Optimized design, high reliability, low dielectric constant, low loss rate, and reduced signal loss.
(4) Channel switching: Durable logic relays are used to achieve the shortest signal path switching.
