How To

If you create a Stereo Pair using the JBL Portable App and you come within range of additional PartyBoost compatible speakers while they are ON, the app will find these speakers. This will break the stereo pair and create a mono PartyBoost group that includes all active speakers that are in proximity. This only happens when the JBL Portable App is actively running on the source device, including when it is running in the background, and when these other speakers are ON. To avoid this scenario, make sure the app is completely closed, without running in the background before coming near any additional PartyBoost speakers that happen to be ON.

NOTE: The Portable App does not need to be running in order to enjoy Stereo sound from two speakers

The new PartyBoost does not support the previous Connect and Connect+ features. For example: You will not be able to successfully connect the new PartyBoost enabled Flip 5 with a Connect+ enabled speaker like the Pulse 3 or Flip 4. You will not be able to connect the Boombox 2 to the original Boombox speaker.

If you are experiencing sound fading in and out (pumping) or volume levels changing while playing your instrument, this is known as limiting. The sound being sent into the PARTYBOX may be too loud which will cause the limiter in the speaker to kick in. This can cause the volume levels to dip. This is done to protect the speaker from playing louder than it’s rated output, and it likely means that the instrument input level on the PARTYBOX is set too high. Please perform these steps to calibrate your input level and to prevent pumping:

1.  While music is playing via BT or line input, set the volume on the PARTYBOX to a comfortable listening level.
2. Stop playing the music.
3. Turn the instrument/guitar input volume on the PARTYBOX all the way down.
4. Connect the instrument to the instrument/guitar input on the PARTYBOX.
5. Set the volume on your instrument to max.
6. Start playing the instrument and begin turning the instrument/guitar volume on the PARTYBOX up. The instrument should sound perfectly normal without any pumping or swelling. Continue to turn up the volume until you start to notice pumping or swelling. When you hear this, turn the volume back down a little bit until the pumping completely stops. You have now calibrated the input level for that instrument. During this step, as you are turning up, if it gets too loud, turn down the main volume on the PARTYBOX to a comfortable level, and then continue.

You should now use the main volume on the PARTYBOX to set the loudest volume for your instrument and can use the volume control on your instrument to adjust the level up or down.

NOTE: Whenever connecting a different instrument, you will likely have to repeat this process as all instruments (guitar pickups) have slightly different output levels. This is how you can ensure maximum performance out of your PARTYBOX.
