How to Set up Your RPB-KAR:

What’s in the Box:

  • Bluetooth speaker
  • Microphone
  • USB charging cable
  • Carry strap (included but optional to use it)
  • 3.5MM to 3.5MM aux cable
  • Owner manual

Description of RPB-KAR:

The RPB-KAR is our extra-large portable speaker with a built in mic input for Karaoke. The built in handles and included strap make it very convenient to travel with this speaker.

Sound
The RPB-KAR has incredible sound quality. It has a 20 Watt RMS amplifier built in and it goes surprisingly loud while maintaining a balanced sound with very defined and punchy bass.

Karaoke
The RPB-KAR comes with a microphone that has good sound and performance. We also added a slight amount of echo onto the mic input (The echo is NOT adjustable).  The speaker also has built in LED lights that go to the beat of the music. You can turn off the LED lights by holding the M button down which will make the battery last even longer.

USB with Powerbank!
The USB input has 2 functions. You can play music stored on a thumb drive or you can use your phone charging cable to charge your phone through the USB!

Big Battery!
The RPB-KAR uses a 7.4v/3000mAh Lithium-ion battery which supports up to 24 hours of playback at 20% volume, 12 hours of playback at 40% volume, and 4.5 hours of Playback at max volume. We also added 5 LED’s that tell you how much battery life you have left. We made sure to add this because it’s a buzzkill when you want to party and unexpectedly have less battery life then you had planned for.

Carry strap
We include a carry strap that is super useful for many situations. The strap is easy to attach or detach so when you are just listening to music in your bedroom you do not need to use it. But we included it because we thought it would be cool for school teachers who want to wear the speaker while talking into the microphone. It is also cool for karaoke because you can wear a loud LED speaker while you are singing. It is fun and useful for many applications so we included it.

Weather Resistant
This speaker is weather resistant and contains a rubber cover over the input terminals which protects the unit from rain and dust
