Sinfoni Presto 50.2 amplifier 2-channel

It features a core function that separates the total gain adjustment of the two channels (this function is equivalent to input sensitivity, input level limiting). Experienced car audio conversion technicians, in the car with extremely complex acoustic conditions, can be used to debug the satisfactory sound effects of right and left volume balance and sound image positioning. With a supply voltage of 12V and a load of 4Ω, the QUARTORIGO presto 50.2 produces a 50W × 2 power output, which is quite sufficient for most mid-range to mid- to high-end automotive speakers.

However, the capabilities and potential of QUARTORIGO presto 50.2 are not limited to this. Under the condition that the power supply voltage is raised to 14.4V when the load is 4Ω, 72W×2 power output can be generated, and the increase of nearly 50% is quite amazing; when the load is 2Ω, it can generate 125W×2 power output. If the left and right channels are bridged, a power output of 250W × 1 can be generated under the condition of a power supply voltage of 14.4V and a load of 4Ω. As can be seen from these objective test data, QUARTORIGO presto 50.2 has a large power margin, excellent quality and deep potential.
