| Features: 1. Power Toroidal Transformer and high resistance capacitors, allows supplying, charging and releasing transient more easily and stably, leading to more headroom margins. 2. Premium high wattage transistors, powerful yet accurate, while significantly reduce heat occurred in conventional amplifier. 3. Professional design of panel, more delicate and elegant. 4. Optimum cooling and ventilation system. Heat tunnel structure, effective heat sink. What's more, the smart fan can adjust the speed according the temperature, allowing more tranquility and reducing unnecessary power consumption. 5. Unique limiter control circuit, preventing the amp from distortion destroy. 6. Other protections: overload, thermal, short circuit protection. 7. The combination of international standard parts, well-crafted PCB and constant temp. dip soldering make a more reliable integrated circuit. This power amplifier adopts symmetric, complementary and bi-differential circuitry, increasing the CMRR considerably, while zero-crossing and zero-distortion. Original 150W triodes with powerful output work in parallel to reduce output impedance, damp the excursion efficiently under good, tight control. What's more, the comprehensive protections include soft start, middle-point DC output drift(+/-1.02V), output short circuit, temp, overload and auto limiter circuitry. Else, two built-in low noise, high flow cooling fans for heat dissipation makes this amplifier more reliable and durable. This amplifier features multi-outputs : 1.Full range L.R. output. 2.Full range BTL output. 3. Subwoofer L.R. output. 4. Subwoofer BTL output. The LF is full of power and bounce, while HF transparence and clarity.
