Q50 STA350 Digital Power Amplifier Board Kit w/ Coaxial Optical USB Input Support 2.1 & 2.0 Modes

Q50 STA350 Digital Power Amplifier Board Kit w/ Coaxial Optical USB Input Support 2.1 & 2.0 Modes

Description:
Q50 power amplifier board adopts pure digital amplification technology. Supports audio modes, including optical fiber, coaxial and computer USB inputs. USB high-end modules are suitable for computers, LCD TVs, set-top boxes, digital boxes, Blu-ray and HD-DVD devices. Each channel outputs 50W (in 2-channel mode), which can meet the listening requirements of most people.

Q50 power amp board adopts digital power amplifier STA350BW which is specially designed for digital modulation technology products. Support any PWM modulation scheme of other brands (such as three-value incremental, phase-shift or two-value incremental modulation technology). BiCMOS-DMOS process technology manufactures this new amplifier chip. This technology allows the integration of DMOS power stages, bipolar transistors and CMOS structures on the same chip. Support all frequencies from 44.1K to 192K. There is no popping sound at special frequency points.

With treble and bass adjustment, support HIFI mode of pitch pass-through function.

Q50 amplifier board adopts FFX technology. FFX series products are characterized by high sound quality, low power consumption, and environmental protection. Simple start-up technology is used to make its circuit accurately control power supply sequence, which improves the reliability of sound system.
