Four-channel Fixed-resistance Power amplifier, High power, portable


Product features:

1: NEW MD component technology, long-term selection of devices, products stable and reliable;

2: The transistor directly contacts with the radiator, dissipates the heat quickly, the automatic variable speed fan, the optimized heat dissipation system, lets the whole machine work stably;

3: The automation of the process greatly reduces the artificial, integrated assembly, reducing the artificial damage;

4: Unique short-circuit lock and automatic determination of reset function, so that customers more reliable visual performance;

5: More than 200 items of fine test, each index is excellent;

The new F series four-channel fixed-resistance amplifier, it is outstanding performance, with load capacity, can be in full-frequency and ultra-low-frequency speakers in performance. This is a small size, light weight of the ultra-high-power amplifier, for the speaker to provide a strong and pure sound. POWER AMPLIFIER ADOPTS HYBRID TD engine structure, which can provide stable signal processing ability in the whole power range. It has the advantages of high power, portable and so on.

Accurate amplification, true reproduction of sound density.
