【RMS 4x40W + Active Subwoofer ONLY】– It offers you the peak power output of 800W in total which lets you drive 2 pairs of high capacity speakers (Recommend to connect speakers with rated power less than or equal to 40W) and an ACTIVE Subwoofer. (For this S-299 amplifier subwoofer output, you have to connect with ACTIVE Subwoofer. WARNING: A PASSIVE Subwoofer is NOT ACCEPTABLE for this amplifier.)
【Hi-Fi Sound BUT NOT STEREO】– It has a high capacity transformer that gives you clear sound without any distortion. It has a harmonic distortion less than or equal to 0.04% this helps you listen crystal clear and sharp music. (NOT surround stereo sound, perfect for listening to music. Not recommended for stereo gaming.)
【Multiple Connectivity】– Latest Bluetooth 5.0 version that gives you a large operating range of 30ft. You can connect it with your music streaming devices like pc/mobile/laptop either with Bluetooth connection, 3.5mm AUX Cable or Headphone Jack. It also supports USB Port, SD/TF Card port. (NOTE: Please keep the distance within 30ft / 10m between the device and amplifier without any wall blocking. But if you are connecting with PC devices, please keep the distance within 15ft / 5m.)
【2 Separate Volume Controls】– The front panel of the amplifier has two independent volume control knobs that allow you to control the volume of two groups of speakers separately as you wish. For example, when using it in your back yard, 2 speakers around your pool area and 2 around the yard and outdoor bar area. You can have each zone at a different level. Louder at the pool where kids are playing and softer at the bar so people can talk.
【Easy Operation】– With bass and treble control knobs you can enjoy the music output as per your wish. Bright digital LED display lets you see the settings you change easily. Its remote-control feature allows you to change audio settings from distance making you less tired and more comfortable. Package comes with DC12V power adapter & remote control.
