Product Description

Features

 

The original main capacitor is the original NICHICON 100000UF, and it is currently upgraded to a new imported original NICHICON 150000UF. The reserve capacity reaches 600000UF total capacity. The A-75 is the successor to the classic A-60. The new technology of accu-phase has been integrated and some circuits have been improved, and the components have been upgraded accordingly. This advanced stereo rear stage uses Mosfet field effect tube, with Class A amplified output, rated output up to 480 W× 2 (1Ω ), 240 W× 2 (2Ω ), 120 W× 2 (4Ω ), 60 W× 2 ( 8Ω), and can output 240W (8Ω) in BTL connection mode. Two-channel uses 10 sets of balanced "electric Mosfet" amplifier modules.
Compared with ordinary amplification technology, the fully balanced amplification technology has the advantages of better symmetry, less distortion, higher stability, and strong driving force. A75 has continued many excellent designs, but has made new upgrades and improvements in many key technologies, including an upgraded MCS+ circuit equipped with MCS, a primary buffer amplifier circuit, an improved multi-stage parallel circuit design, and current return. The output design ensures the linear response of each level, connects the amplifier circuit in parallel to reduce noise, and is equipped with a DC stable power supply in the driving section and MCS+ circuit to increase the S/N ratio and improve the purity of the sound.
In order for the machine to have sufficient and stable power supply, the power supply part uses a 1200VA high-efficiency large-scale transformer with two 82000μF filter groups to provide sufficient and stable power supply. The substrate with low dielectric rate and low loss rate is used, and the main parts such as the input terminal are gold-plated to improve the sound purity. Ultra-large speaker output terminal, convenient for access to fever speaker wire. The front panel adopts a fully digital display of the working mode of the machine, and is calculated by a DSP digital circuit to display the output power and working status.
