PA-1 is pure mono block power amplifier with 230W output power. It is good on the high fidelity on music performance and with fashion enclosure design. Its sound has high solution, wide sound field, balanced feeling and exactly focus. PA-1 adopts current negative feedback amplifying circuit. The current amplifying part is three grades Darlington circuit, and the output transistors are four pairs of heavy current SANKEN pair transistors, whose peak current is 68A. There are two pieces of 300W toroidal transformers. The total capacitance of the filter electrolytic capacitance for main power is 100000uF/80V. The bridge rectifier adopts four pieces of 50A square bridge in shunt-wound to decrease the internal impendence of power supply parts, increase the drive power under high dynamic. Specification: ? Output Power: 230W/channel (8ohms load) ? Input Sensitivity: 2V ? THD: <0.02% ? SNR: 100dB ? Frequency Response: 10Hz~100KHz (-1dB) ? Damping coefficient: 140 ? Power Consumption: <200W
