Digitally Controlled Stereo Electronic Audio Volume Control Module VC01-M62429



Mean Well SE-1000-48 48V 1000W AC/DC Switching Power Supply




This stereo audio amplifier board, based on Class D topology and Sure Electronics’ T-AMP technology, delivers high output power as 500W per channel into a 3Ohm load in 4.8’’ x 3.6’’ size, featuring high efficiency up to 95% and high sound quality with low distortion and low noise level. Easy installation, high reliability and high output power makes this audio amplifier board suitable for soundbar, home theater, DIY audio, car audio, kiosk and demanding industrial applications. A DC25V – 50V power supply is required.

High Quality Audio Performance

By means of dedicated PCB layout design and engineers’ attentive debugging, this high power audio amplifier board features high audio performance with THD+N performs well as 0.0076% @ 3Ohm, 1W, 1kHz.

High Reliability and Long Service Time

A low noise, temperature-controlled fan together with an optimized robust heatsink are mounted atop the amplifier board to ensure sufficient heat dissipation even in rough environment, so you don’t need to worry about overheat. Built-in chip protection, ESD and spike protection components used throughout input and output of the amplifier board ensure its robustness and reliability. Full protection circuit, like over temperature protection and overcurrent protection, is equipped on this board to extend the longevity of the amplifier module.

Easy for Installation

Four screw holes provided make this amplifier board easy for installation and quick for integration in any cabinet. Thanks to the pre-mounted industrial terminal interfaces, all you need to do is to plug in cables for connection, without any demand of soldering, which is swift and convenient. Power and clip indicator are provided on board for customers to have an overview of the running condition of the amplifier board. Shutdown function is offered for simple control of the amplifier board.

External Volume control

This high power amplifier board supports WONDOM plug-in volume control module (VC01). You can adjust volume through the potentiometer board.

Hi, if I connect RCA inputs to on-board RCA jacks, the noise level is unusably high (without the potentiometer board + the signal comes from hifi preamp ) - If I enable the potentimeter board, the sound becomes clean. What should I do to use on-board rca jacks? any grounding required?

Hi, Jonghwan. Connection, power supply, audio source and other elements would play a joint role in the final audio quality. Could you please send us a picture or a video of your audio system with a clear show of connection? You can send emails with pictures or videos to store@sure-electronics.com. We will give you solution and advice after we see your audio system. Wish this could help you. Have a great day~

Hi, how do I use audio input J2? is there any special terminal block parts? or can I solder 4 wires from RCA directly to J2? - then why J2 has 8 holes rather than 4? How do I input-select J2 rather than RCA jack?

Hi, Jonghwan. Thank you for your interest in our products. You can directly input audio through J2 instead of RCA jacks. The optional terminal interface for J2 is KF141V. Please refer to the silkscreen on the board for the definition of this port as CH1, GND, GND, CH2. Each two holes in a row is connected so the functions are the same. You can also solder 4 wires to J2 for audio input. Wish this could help you.

Hi, any damping factor specification for this board?

Hi, Jonghwan. Thank you for your interest in our products. This amplifier board employs Class D topology, therefore, it has sufficient current driving ability. We employ BTL architecture so the output impedance is very low. As long as the load of the speakers used in audio applications is within the recommended range, this audio amplifier can work stably and reliably. Please note that the amplifier board is designed for audio applications, so we do not provide the damping factor to retail customers. If you want to use this board for non-audio applications, please contact us with store@sure-electronics.com to send us your detailed requirements so that we can provide a solution and related specifications for you. Wish this could help you.

Hi!, Can I use this amp with 8 ohm speakers?

Hi, Jonghwan. Thank you for your interest in our products. Yes. You can connect this audio amplifier board with an 8Ohm speaker. But please note, the output power would be lower as around 144W@48V when driving an 8Ohm speaker. Wish this could help you.
