30W Dynamic Power in a Compact Cabinet

Despite its compact dimensions, the BA30 delivers 30W of dynamic power through a 4" / 30W full-range speaker. JOYO has professionally tuned the cabinet to provide a tight and punchy low end while maintaining clear midrange and high-frequency response.

The compact cabinet incorporates an internal reinforcement structure and sound-dampening materials, helping minimise unwanted cabinet coloration and maintain a more controlled, focused sound.

At only 2.7kg, the Vibe Cube is easy to transport for practice sessions, rehearsals, recording and portable playing.

Built-In Compressor

The BA30 includes a built-in Compressor effect designed to help balance playing dynamics and smooth out harsh attacks.

The adjustable compression control can help produce a fuller and more even bass tone, making the BA30 particularly approachable for players developing their dynamic control.

Flexible 3-Band EQ with Mid Frequency Control

The Vibe Cube features a dedicated EQ section with:

• BASS – Low-frequency tonal control
• MIDDLE – Midrange tonal control
• TREBLE – High-frequency tonal control
• MID FREQ – Selects the centre frequency of the midrange adjustment

The MID FREQ control provides a frequency range of 200Hz–2000Hz, allowing more precise control over the area of the midrange being shaped.

Bluetooth 5.1

Built-in Bluetooth 5.1 provides a convenient wireless connection for playing music and backing tracks through the BA30.

The high-fidelity Bluetooth system is suited to practice sessions, allowing backing tracks, tutorials and other audio content to be played through the amplifier without requiring a wired connection.

OTG Audio Interface for Recording & Streaming

The BA30 doubles as a compact OTG audio interface through its Type-C USB connection.

Connect a compatible smartphone or computer to use the Vibe Cube for applications such as:

• Recording bass tracks
• Live streaming
• Content creation
• Vlogging
• Music composition
• Playing backing tracks

The dedicated OTG VOL control provides independent control over the OTG recording output level, helping manage recording levels and reduce the risk of clipping caused by excessive input levels.

Silent Practice

For quiet practice, the BA30 features a 3.5mm stereo headphone output with support for headphones with a 32Ω impedance.

The headphone output allows the full-range sound to be monitored privately, making the Vibe Cube suitable for late-night practice and other situations where keeping the amplifier speaker silent is preferred.

Flexible Power Options

The BA30 is supplied with a DC 20V/2A power adapter and also features a USB PD2.0 power interface supporting 65W or higher updated versions.

This provides additional flexibility for portable setups when using a compatible USB PD power source.

Important: When using the DC power input, use the supplied JOYO power adapter or an appropriate replacement matching the specified voltage, polarity and power requirements.

Compact & Portable Design

The Vibe Cube's compact cabinet measures just 182.5 × 165 × 215mm and weighs 2.7kg, making it substantially easier to transport than a conventional bass amplifier.

Its compact format makes it suitable for:

• Bedroom and home practice
• Bass beginners

• Outdoor use with a suitable power source
