Features
● The excellent straight-line short-distance heat-closest air path design, combined with the feather-shaped aluminum foil, greatly increases the contact area with the cooling airflow.
● All power tubes are directly pressed on the copper plate, and in a vertical manner, so that the heat can be evenly conducted. The traditional duct-type heat sink will cause the last few power tubes in the air path to gather the heat emitted by almost all the power tubes in front, which is the reason why the traditional power amplifier and heat dissipation method have a high failure rate.
● The fan high-speed dust removal function when starting up, stepless speed change, overheat full-speed air cooling control circuit, provide better heat dissipation effect, intelligent pressure limiting circuit, in the case of overload, the power amplifier output is not clipped.
● Full-function protection: soft start at startup, overload, overheat, short circuit, DC output, peak pressure limiting, intelligent peak clipping protection, output zero current switch.

Q: How does the core technology of a Pro Amp (2×350W) achieve high power output stability and low distortion?
A: The professional pure post-stage amplifier (2×350W) ensures stability and high fidelity at high power through the following technologies:
Class-H high-efficiency topology: dynamically adjust the power supply voltage (such as ±50V to ±100V), use low-voltage power supply to reduce energy consumption when the signal is low, and automatically switch to high-voltage power supply for large dynamic signals, with an efficiency of more than 80%, while reducing heat loss (the full-power operating temperature is 35% lower than Class AB).
Fully balanced signal path: differential amplification design is used from input to output to suppress common-mode interference, signal-to-noise ratio ≥115dB, THD+N (total harmonic distortion + noise) ≤0.003% (1kHz, 4Ω), frequency response range 20Hz-20kHz (±0.05dB).
Intelligent protection system: includes overcurrent, overheating, DC output and short-circuit protection, equipped with a dual-speed temperature-controlled fan and aluminum heat sink fins, supporting continuous full-load operation in a 40℃ environment.
