Sure Electronics is an audio brand located in Hong Kong specialising in producing amplifiers, plate-amps, LED instruments, and other audio components. By maintaining a large stock of Sure audio equipment, we at SoundImports can serve our customers fast and reach the highest customer satisfaction. Sure Electronics develops and produces audio components for well-known manufacturers worldwide. Purchased components and parts are obtained exclusively from the respective manufacturer's official distributors, and all materials used comply with the current guidelines and regulations. The products undergo a function test before delivery, which guarantees fault-free function and minimizes the risk of failure. The boards are designed according to industrial criteria, with special attention to stability, durability, and robustness.
Sure Electronics renamed its consumer division: all printed circuit boards and finished products are sold under the brand name "Wondom".
Hereby are briefly described the amplifiers by Sure Electronics that we are offering at SoundImports. The Sure Electronics AA-AS32157 integrates a high-quality rotary encoder that employs high-quality digital volume control IC ensuring precise shaft rotation and accurate volume adjustment. This product supports dual-channel amplification, and each channel is rated at 15W. The Sure Electronics AA-AS32171, besides traditional RCA input jacks, a stereo phone jack is provided to make it much easier to use your second devices such as a mobile phone or portable players. A high-quality headphone amplifier is also provided at the front panel. It supports dual-channel amplification, and each channel is rated at 50W. They both have a built-in MCU; it can provide over/under voltage protection, low current protection, and display LED state. The Sure Electronics AA-AS32971 is a Class-D audio amplifier board that gives you 2 x 100 watts using T-AMP technology. Using PBTL (Parallel Bridge-Tied Load) topology, you get 50 watts RMS per channel with only 0.01% THD at 4 ohms.
Being a family member of the Mid Power Stereo Series, the Sure Electronics AA-AB32971 amplifier board can deliver 100W per channel into a 4 Ohm load. Sure Electronics T-AMP technology not only achieves high efficiency, up to 93% but also delivers the best sound possible from a Class-D board for your audio project. The optimized heatsink design with a temperature-controlled fan provides enough cooling for most applications and eliminates your worry over heat dissipation. Over-temperature protection, over current protection, and over/under voltage protection are also included to ensure its reliability. Mounting holes are provided, as is a 2.5 mm x 5.5 mm power jack for quick connection. Screw-down phoenix-type terminals are included for quick speaker wire connection. RCA line-level inputs are pre-attached to make this board ready to rock. The Sure Electronics AA-JA32172 is an All-in-one stereo Class D audio amplifier board integrated with high-performance DSP – ADAU1701, outputting 50W per channel into a 4Ohm load based on Texas Instruments TPA3116 chip. With the integrated DSP chip, JAB3 can be applied to various DIY audio, commercial or industrial applications such as digital crossover, bass enhancement, loudspeakers, etc. After connection with WONDOM’s programmer – ICP series, JAB3 supports programming with SigmaStudio, remote control through APP, or PC UI. The Sure Electronics AA-AB32189 is a dual-channel Class D amplifier board featuring a state-of-the-art TDA7498 IC to achieve high efficiency of up to 92%. Each channel is capable of producing up to 100W into a 6 Ohm load. A low noise cooling fan is mounted atop the robust heatsink to maximize heat dissipation. Various protection ranging from thermal, over/under voltage protection to current protection circuit ensures the amplifier board's longevity and durability. Three fixed gain settings are available to allow for volume control at the source, and stereo RCA line-level inputs are pre-attached. Mounting holes are pre-drilled to work as a 2.5 mm x 5.5 mm power jack for quick connection. The board employs screw-down phoenix-type terminals for quick speaker wire connection.
