The Trulli Bass50 is designed to be intuitive, but under the hood, it’s full of power and precision. This guide walks you through every control on the unit so you can confidently operate your Bass50 in any setup.
For remote and app-specific details, check out our full Trulli App Guide and our Using the Bass50: Vehicle Upgrade Setup application guide.
Main Control Panel
All primary controls are located on the front face of the Bass50. The LED ring wraps around the – button, Trulli button, and + button, providing live visual feedback as you make adjustments.
A. Trulli Button (Center Button)
- Turn On: Press and hold for 1 second, then release
- Enter Standby: Tap once
- Turn Off: Press and hold for 7 seconds
Tip: Use standby mode when stepping away briefly. It conserves power but keeps the system ready.
B. - and + Buttons
Volume Controls
- Increase Volume: Tap or hold the + button
- Decrease Volume: Tap or hold the – button
Bass Gain Controls
- Increase Gain: Hold + and the Trulli Button together
- Decrease Gain: Hold – and the Trulli Button together
C. LED Ring Feedback:
- Gain up = fades out from the right
- Gain down = fades out from the left
- Volume increases = clockwise sweep
- Volume decreases = counterclockwise sweep
Tip: Bass gain adjusts the strength of low frequencies, not the overall loudness. For the full breakdown, see: What is the difference between Volume and Gain?

SKAA Wireless Controls
The SKAA controls are located beneath the right-side rubber flap on the Bass50. These allow you to cycle through different SKAA connection modes and optimize wireless performance based on your setup.
SKAA Control Panel Overview
Cycle Mode Button
You can cycle through connection modes by pressing the cycle mode button. LED indicators will illuminate to indicate which mode you are in
Host Mode
The Bass50 acts as the main speaker (transmitter).
Connect your device to the Bass50 via Bluetooth, AUX, or USB, and the Bass50 wirelessly transmits audio to SKAA-enabled speakers.
Common Use: When using the Trulli Vehicle Kit or linking multiple SKAA speakers.
Bypass Mode
SKAA wireless transmission is turned off.
Common Use: When using the Bass50 as a standalone sub via AUX or USB input.
Receiver Mode
The Bass50 receives audio from another SKAA-enabled transmitter (such as a second Bass50 or a SKAA transmitter like the Dani).
Common Use: Part of a larger wireless setup with multiple speakers.
Tip: Most users will stay in Host Mode for wireless setups. If the Bass50 isn’t sending sound to another device, double-check it’s not accidentally set to Bypass or Receive

Final Notes
The Bass50’s onboard controls give you full command over its behavior, without needing an app, remote, or screen. Whether you’re setting up in a car, on stage, or at home, understanding how each button functions helps you dial in the perfect experience.
