Mean Well LRS-350-36 36V 350W AC/DC Switching Power Supply




This Class D stereo mid-power audio amplifier board employs TDA7498E amplifier IC as the driver and delivers 160W output power per channel into a 4Ohm load. It features high efficiency up to 95% and high sound quality with low distortion and low noise level. Easy installation, high reliability and mid power output makes this audio amplifier board suitable for home audio, DIY audio, desktop amplifier, car audio, home theater and demanding industrial applications. A DC15-36V power supply is required.

High Quality Audio Performance

By means of the dedicated PCB layout design and engineers’ attentive debugging, this mid-power audio amplifier board features high audio performance, whose SNR reaches 87dB and THD+N performs well as 0.032% @ 4Ohm, 1W, 1kHz.

High Reliability and Long Service Time

An optimal heatsink along with a low noise cooling fan is mounted atop the amplifier board to maximum the heat dissipation, which improves its stability. Mute and Standby functions are offered with this amplifier module for easy control. Full protection circuit, like over temperature protection and overcurrent protection, is equipped on this board for high reliability and long service time.

Easy for Installation

Four screw holes provided make this amplifier board easy for installation and quick for integration in any cabinet. All the necessary terminals for power supply, audio input and audio output are pre-mounted on the board. Therefore, you only need to plug in the cables and enjoy music without any need of soldering. If you want all the terminals to be mounted for your applications, please contact us. MOQ would be required.

Four Stages Gain Adjustable

This audio module provides four stages gain for customers’ choice as 23.6dB, 29.6dB, 33.1dB and 35.6dB. You can select the most suitable stage for your application. The switch among the four stages gain is achieved by the different combination of the two switches on the board, no need of complex operations.

Can the gain on the channels be individually adjusted or do both channels share the same gain controls?

Hi, Jeffrey. Thank you for your interest in our products. The gains of the two channels are the same and share the same gain controls. You can adjust the gain through the switch provided on the board. Wish this could help you.

Can the channels on this item be bridged?

Hi, William. Thank you for your interest in our products. This board do not support parallel bridge tied load mode. You can check this info on the 'Basic Information' session of the product detailed page. Wish this could help you.
