Frequently Asked Questions

How many watts does the Busker output?

The Busker's 6.5'' woofer can output in two different modes. In standard mode, the Busker outputs at 150 W peak. In Eco Mode, it outputs at 50 W Peak.

What are the inputs on the Busker speakers?

Each Busker has two Combo XLR and TRS jacks that support both balanced and unbalanced audio for channels 1 and 2.  Channel 3 is a dedicated auxiliary channel, receiving audio via AUX input or Bluetooth signal when you pair a supported Bluetooth Device.

How do I pair my Busker with a Bluetooth device?

To connect the speaker with a Bluetooth device follow these steps: 

  • Hold down the pairing button for 3 seconds to initiate pairing.
  • The blue LED on the speaker will flash indicating that it is in pairing mode.
  • Navigate to your device's Bluetooth device list and select ”Busker” to connect.
  • Once paired there will be a voice prompt stating the connection was successful, and the blue LED will be lit solid. 

Note: Pressing the pair button while in pairing mode will cancel the connection.

The Busker has a stereo link mode that will allow two Busker speakers to be paired wirelessly. To set up the stereo link mode do the following steps: 


  • Connect one speaker to Bluetooth following the steps above. This will be the primary speaker.
  • Hold the pairing button for 3 seconds to initiate stereo link. Do this for both speakers.
  • Both speakers will beep to indicate they are in scanning mode, and the orange LED will blink. When they find each other, they will link automatically.
  • Once the two speakers are successfully linked, there will be a confirmation chime, and the Orange LED will be lit solid.
  • Press and hold the pair button on either speaker to disconnect. 

Once the speakers are in the stereo link, the Bluetooth Volume knob on either speaker will control volume for both speakers


  • If you link the speakers first, only one speaker will connect to Bluetooth.
  •  If pair mode is activated on both speakers (pair button held for 3 seconds), you may encounter trouble linking until pair mode is cancelled or times out. 
  • The stereo link is only for Bluetooth signal only. 

Mix Out does not include Bluetooth signal, only analog inputs. 

Why are there Mic/Line switches, and what do they do?

The Mic/Line switches let you select your input so that you can turn up the volume without fear of overdriving your Busker. If you are unsure of whether your input is Mic or Line, start with Line first and make sure your source volume is up sufficiently high. If this is still not loud enough, turn your volume all the way down, switch to mic, and turn up until an appropriate volume is reached.

Note: The Busker is optimized to provide maximum output for your source when the volume knobs are turned all the way up (5 o’clock).

What do I do if there is a delay between my linked speakers?

If you experience a delay between two linked speakers, please first try pausing and restarting your audio. If that does not work, try powering off both speakers and then re-linking them. 

What are the included FX?

Reverb Effects 

  • HALL 1: A large, bright concert hall reverberation effect suitable for vocals and instruments. 
  • HALL 2: A large, warm concert hall reverberation effect suitable for drums, piano and other instruments. 
  • ROOM 1: A medium-sized, moderately bright reflective room reverberation effect suitable for vocals, lead guitars and other instruments. 
  • ROOM 2: A small, very reflective bright room reverberation effect suitable for drums and percussion as well as electric guitars and other instruments. 
  • ROOM 3: A large, warm room reverberation effect suitable for acoustic instruments. 
  • PLATE 1: A lush, smooth vocal plate reverb with a long decay time and warm tonality. 
  • PLATE 2: An emulation of vintage plate reverb with bright, slightly tinny tonality and a medium-length decay. • 
  • PLATE 3: A short, bright plate reverb effective for creating subtle spaces. 

Modulation Effects 

  • CHORUS: A complex, 6-voice chorus ensemble effect with short delays often referred to as a “Chorus / Doubler”. Discrete stereo signal path. Slow and watery. 
  • FLANGE: Classic stereo flange: a slow, slightly metallic sweep with a discrete stereo signal path. 
  • ROTARY: Fast rotary speaker simulator creates the classic, lush Doppler effect of an organ’s spinning horn. Effective on guitars, vocals, keyboards and other instruments. 

Delay Effects

  • DELAY 1: A simple slap-back echo with no feedback particularly effective on vocals and rhythm guitars. 
  • DELAY 2: Medium-length poly-rhythmic delay with crossover feedback. 3 to 4 ratio between L and R delay times (291 to 388ms) for 3/4 vs. 4/4 feel. Useful for solo instruments where a long, trailing echo effect is desired. 

Multi Effects 

  • CHORUS/ROOM 1: Room reverb into a slow flanging modulation creates a spacey effect. 
  • CHORUS/ROOM 2: Fast modulation provides a dramatic chorus effect in a small room for a very lush chorus + reverb sound with a discrete stereo signal path. BYPASS: Bypasses the effects processor – no effects will be heard. 

What is the power output of the USB charge output on the Busker?

The USB Charge output size is 5v, 2.1A. This output is used for charging devices, and cannot be used to stream media from storage or media devices. 

What does the "Speaker Use" button do?

The speaker use button will adjust your speaker to control the output EQ based on what is streaming through your speaker

  • With Sub: The speaker is positioned upright or horizontal on the ground (or other flat surface) facing the audience. 
  • Pole: The speaker is elevated on a speaker stand around ear level facing the audience. 
  • Monitor: The speaker is positioned horizontal on the ground facing the performer. 
  • Via App: This is the custom EQ setting selected from the ALTO Pro App. The default setting is flat. 

How do I adjust the EQ settings on the Busker?

The Speaker Use Presets provide one option for EQ adjustment. For greater control, the Alto Pro app offers a 6-band, parametric EQ for use with the “Custom via App” setting. You can manipulate the available sliders to get the sound you want, and then load it to your Busker by pressing the “Load to Speaker” button. After setting the EQ you want, you can save your favorite settings for later use.

How can I check the FX and volume levels?

Press and hold the Speaker Use button for 3 seconds to activate Volume Display Mode. Volume levels for each channel will be seen from the Speaker Use LED indicators. A channel’s SIG/LIMIT LED will flash to show the active channel. When the LED is lit red, it represents the channel volume. When the LED is lit green, it represents the FX level. The volume will also be displayed when a channel’s volume knob is adjusted. The Volume Display Mode will automatically exit after 20 seconds of no use. Alternatively, press and hold the Speaker Use button for 3 seconds to exit.

How do I turn the voice prompts off?

Press and hold the BT pair and TWS link buttons until you hear “voice off.” To turn it on again, do the same thing until you hear “voice on.”

Note: The voice prompt level is controlled by the BT volume knob.
